Author: MSE Graduate Student Discovers Career Path During Difficult Times

By Harrison Raskin

MSE graduate student Marco Echeverria

Third year MSE graduate student Marco Echeverria spent a second highly productive summer at the Lawrence Livermore National Laboratory (LLNL).

Echeverria says his research focused on using simulations to model the generation of metal ejecta from high-energy experiments with metals and lasers.

“The focus of the simulation effort is to provide an atomistic insight on the process, and to study the microstructural and defects effects on the ejecta formation. Results such as strength values, dominant dislocation types and free surface morphology can be then used in higher length-scale simulations, such as continuum mechanics, to fill the gaps these models have due to their larger scale”

LLNL physicist Alison Saunders, Echeverria’s internship supervisor, said that gaining a better understanding of ejecta interactions has a broad range of applications including spacecraft shielding, cold-spray welding, additive manufacturing and understanding material strength at small scales.

These findings will contribute to LLNL’s primary responsibilityof ensuring the safety, security and reliability of the United States’ nuclear deterrent. The research laboratory is focused on using applied scientific and engineering advancements to support breakthroughs in counterterrorism, nonproliferation, defense and intelligence, energy and environmental security; a few of the many ways in which work such as Echeverria’s can improve the world beyond the laboratory.

Echeverria likes that his work with LLNL is now a direct component to his PhD research. “My (PhD) work focuses on the behavior of materials under extreme environments, such as laser excited shock loading and piston loading. The ejecta studies with LLNL are another type of outcome in similarly extreme mechanical environments, so it all fits together well.” At UConn Echeverria works under the guidance and advice of MSE Associate Professor Avinash M. Dongare, principal investigator of the Dongare Computational Materials and Mechanics research group. Echeverria says that Professor Dongare recommended he attend the 2019 Stewardship Science Academic Programs (SSAP) conference in Albuquerque where he connected with scientists from LLNL. Marco’s graduate research at UConn is part of the Center for Research Excellence on Dynamically Deformed Solids (CREDDS) that is funded by the Department of Energy’s National Nuclear Security Administration (DOE/NNSA). Dongare notes, “One of the top priorities of CREDDS is the ability of the students to engage with NNSA labs.

Marco has been a success story for the center wherein he has worked with the scientists at LLNL to build a strong direction for his PhD research. This is truly impressive for a graduate student.”

Echeverria was one of millions of American students who found their academics restructured by COVID-19. Despite a shift to virtual research jeopardizing positions in most laboratories, Echeverria was able to obtain a completely remote internship.

“My work is in molecular dynamics, so I can do that even if I only have a computer and internet connection. LLNL did an amazing job with all the interns, especially with the tech-support and being remote.”

The laboratory prioritized virtual communication by implementing weekly team meetings and daily interactions with mentors.

Returning to UConn this fall, Echeverria describes some difficulties with virtual research.

“It makes it a little complicated giving it 100 % while always staying in the same environment. Personally, I like to have a place of work and another of leisure. Now, after so many months, I’ve gotten used to having an agenda while working from home, although it is always hard not to take a nap after lunch!”

The positive internship experience also has Echeverria considering working within a national laboratory as a career option.

“I really like the close connection between experimental work and modeling that’s possible in a national lab research environment,” Echeverria said. “It’s exciting to be able to reverse-engineer simulation codes based on experimental results.”

Echeverria received his bachelor of engineering degree in mechatronics engineering from the Central American Technological University of Honduras in 2015, and his master’s degree in mechanical engineering from the University of Puerto Rico (Mayaguez) in 2018. Echeverria joined UConn in the fall of 2018 as a graduate student pursuing a PhD in the MSE department, and is currently the secretary of the UConn Materials Research Society Chapter. His research focuses on the atomic scale modeling of the deformation and failure response of multiphase metallic materials under shock loading conditions.

Digging Into a More Cost-Effective Solar Technology

 

Author: Diving Deeper Into Her Hobbies Sparked an MSE Sophomore’s Passion For Learning About Materials

By Ben Crnic

MSE Sophomore Elise Bessette

For sophomore Elise Bessette, materials science was always intertwined with her hobbies and interests. Being passionate about 3-D printing, Bessette was already familiar with various materials exhibiting different properties. She became fascinated with learning more about why they behaved the way they did, leading her to MSE.

“I don’t think it was any single material that got me interested in MSE. Rather, it was the breadth of materials that grabbed my attention,” Bessette said. Polylactic acid (PLA) is commonly used with 3-D printing because it can be annealed to increase part strength due to its somewhat crystalline nature. Acrylonitrile butadiene styrene (ABS), on the other hand, is sensitive to temperature changes and produces fumes during the printing process.

Learning about MSE also aided Bessette with her robotics team experience while in high school. She was fortunate enough to take some UConn engineering classes at the Storrs campus during this time, giving her some knowledge about plastics which she applied to the robots developed by her team. In particular, she advocated for the use of polycarbonate instead of aluminum for a certain assembly due to its availability, price, and desirable properties. This assembly ended up lasting the entire competitive season. From this experience, Bessette knew she had a passion for studying materials.

Now an MSE undergraduate at UConn, Bessette works in the lab of her advisor, Assistant Professor Lesley Frame. She helps with projects focusing on failure analysis and process improvements, many in connection with the Industry Affiliates Program (IAP)  which is run by the Institute of Materials Science. The IAP assists regional industry with short-term materials-related research and production projects, especially providing tools and expertise which companies may not have. She is also enjoying her MSE classes–her favorite this Spring was “Introduction to Structure, Properties, and Processing of Materials II (MSE 2002)” taught by Associate Professor and Director of Undergraduate Studies Serge Nakhmanson.

“The lectures are always good, and the homework always helps to reinforce the course content. It is also structured so that you have to go and find out further details for yourself,” Bessette said. Of course from the faculty’s perspective, that’s a key part of being an engineer—utilizing what you’ve learned, discovering and applying more, and then assimilating it to achieve a goal.

As for what comes next, Bessette wants to return to her initial passion for materials and begin researching 3-D printing. 

“It is a big hope of mine to be able to work with 3-D printing in the future. While it’s rewarding doing it as a hobby, I would love to be able to advance the science and applications of this rapidly evolving field,” Bessette said. She encourages other MSE students to contact faculty about research regarding their interests.

“If you see an opportunity for research in your email that sounds interesting, reply! There are plenty of professors who are looking for undergraduate students to assist in research,” Bessette said.

Author: To Megan Hurley, MSE is a Close Community As Well As a Fascinating Major

By Ben Crnic

MSE undergraduate student Megan Hurley

Megan Hurley was drawn to engineering and materials science from a young age. In 4th grade, she was already carefully inspecting the different materials inside rocks she had broken open, and in high school she found chemistry and math appealing. When it came time to pick a college major, she knew she wanted to be involved in something to do with materials, and she began to explore UConn’s MSE department. When she discovered the camaraderie and how tight-knit the department was, she knew that it was a perfect fit for her.

“I really like the community and the smaller class sizes. You get to know people and what they like to do, and there is better interaction with the faculty as well. They are all enthusiastic about what they teach, and everyone is nice,” Hurley said.

She was made aware of the MSE department while she was participating in UConn’s BRIDGE program before her freshman year, a five-week summer program designed to prepare students for the rigor of the engineering curriculum at UConn. During this time, she spoke with her tutor at the time, Francis Almonte, who she credits with helping her make the decision to become an MSE major.

Now a junior, Hurley is certain this was the right decision, and is heavily involved in the MSE community. She volunteers for the Engineering Ambassadors, a network of students dedicated to inspiring the next generation of engineers through volunteering at events that promote STEM. She volunteers at events held by the Society of Women Engineers as well, which supports the professional interests of female engineering students as they pursue their degrees at UConn. Hurley also helped younger MSE majors through working with incoming freshmen at the BRIDGE program during one of her summers, and currently assists them through her position as The Major Experience (TME) Mentor for the MSE department. Incoming students are able to reach out to her and ask questions about the major, and she will be assisting with further outreach activities in the future. 

Hurley finds it easy to be involved in the community for her major. She is fascinated by her classes, and there has never been a dull moment throughout her time at UConn.

“I think everything I’ve learned so far is cool, even if it’s a less exciting topic to me,” Hurley said.

One such course that struck her interest was MSE 3004 Mechanical Behavior of Materials, which was taught by Assistant Professor Seok-Woo Lee. In one class, Professor Lee gave a demonstration of the effects of shear force on a single crystal created at the nano-scale, which is a sample where the crystal lattice is continuous throughout. The demonstration involved a tensile tester which pulled apart the dog-bone shaped sample and recorded how the individual atoms in the crystal responded to the applied shear forces. Hurley was captivated by this demonstration.

“I’ve always liked how slight changes to a material can alter a multitude of its properties and characteristics,” Hurley said.

Once the UConn campus opens again for research after being closed due to the COVID-19 pandemic, she intends to perform a nanoindentation study on shock-compressed magnesium single crystals. The investigation will focus on the hardness of the material, specifically how it is influenced by the presence of twin boundary defects that form from prior mechanical shock. Studying the hardness in this way is valuable because it provides knowledge of the connections between materials properties, processing, and applications. The shock loading will be performed at two different speeds and will impact the samples with two different orientations, which should create a variety of defect distributions in the structure for further analysis.

Such research is essential because single crystals are often used in engines or turbines, where uncontrolled defects can be disastrous. It is therefore crucial to understand how the material responds to stresses similar to those encountered during normal operation in the typical environment, and how the properties of the material are altered as a result of this stress.

Hurley has some advice for the newer MSE majors she mentors: they should not be afraid to reach out to professors about their own research interests in order to explore ways to pursue such subjects.

“Just reach out, it might seem daunting and scary but once you start talking to professors after class it can open doors. Suddenly, you’ll find yourself doing research,” Hurley said.

She would also like to share her life motto, which she repeats to herself when she faces difficult challenges and urges others to do the same:

“You got this, even when you don’t think you do.”

Author: Thanks to the Work of MSE Alumnus David Wikholm, Robots May Become Lab Assistants

By Ben Crnic

MSE Alumnus David Wikholm (2013) holding a Rover lab automation robot.

MSE Alumnus David Wikholm (2013) is used to being on the front lines of innovation: he currently works on pioneering robotics technology in his position as Product Manager and Research Engineer at Formulatrix Inc. in Bedford, MA, a company that develops laboratory automation solutions, including the next generation of liquid handlers using microfluidic technology. Wikholm considers his MSE background invaluable in preparing him for his professional life and giving him a unique perspective on the engineering problems he encounters during his projects, as well as giving him the skills needed to make breakthroughs in his work.

“The MSE department emphasized engineering problem solving as a process in the context of materials science. Through my studies in the department, I learned an approach to solving engineering problems that is transferable to any division of engineering. I would say that this, combined with the research-oriented nature of materials science, prepared me well for a career in research and development in any engineering field,” Wikholm said.

One of the projects to which Wikholm is applying his problem solving skills is called the Rover, a mobile robot that helps with lab automation and serves to connect instruments together to move materials between them. The Rover assists with moving experiments between the different instruments, and is packed with sensors that make it smart and aware.

Another project Wikholm is developing is called the FLO i8 liquid handler, a robotic pipettor that transfers specific volumes of liquid to perform experiments in labs. Wikholm contributed to one of the first major developments on this project, which was a novel pipette tip design with two conductive strips down the sides and resistance-based sensing to enable real time tracking of the liquid level as it rises and falls in the container.

The Rover, a lab automation robot that David Wikholm (2013) is working on with Formulatrix

During his undergraduate career, Wikholm carried out research in the lab of his academic advisor, MSE Professor Puxian Gao, which centered on evaluating the behavior of certain cells when exposed to nanomaterials.  He also explored methods to create uniform growth of zinc oxide nanowires on microbeads for use in the cell biology experiments.

The focus on biology fit Wikholm’s interests, as he first became fascinated by MSE through biomaterials, and was interested in the concept of creating 3D structures to grow tissues or entire organs in a lab. Professor Gao looks back fondly on Wikholm’s research and is proud of his work.

“David is one of the very dedicated students who got involved in our materials research during his sophomore year. I am very glad to see the continued devotion and success in his young career,” said Gao.

Ultimately, Wikholm ended up choosing MSE as a major because he viewed it as an essential field.

“I saw that materials science and engineering as a subject is quite fundamental and relevant to many fields of engineering, especially in various fields of cutting-edge research that I find interesting. I am captivated by the ability to unlock totally new applications and solutions by creating new materials,” he said. His favorite course during his time at UConn was MSE 3002, Transport Phenomena in Materials Processing, taught by Professor Harold Brody.

“This course really taught me how to navigate any real-world engineering problem and work through a solution. It was a major challenge, but it was rewarding,” Wikholm said.

Wikholm ended up completing a 5-year dual degree program called EUROTECH, which leads to BA in German and BS in engineering and is designed to emphasize national strengths in particular engineering fields.  In order to complete this program, he spent a year abroad in Stuttgart, Germany, taking classes for one semester and working as a research intern at the Fraunhofer Institute for Interfacial Engineering and Biotechnology for the other semester.

“I had always wanted to study abroad and had also been interested in learning and using a second language. It seemed like a great opportunity to achieve both of those goals,” Wikholm said.

At his internship at the Fraunhofer Institute, Wikholm worked in the materials lab to research methods and materials to disperse nanoparticles in a solution, and carried out experiments to lay the groundwork for a study of the toxicology of nanoparticles. He credits his work in Germany as giving him the ability to recognize and navigate cultural differences, especially in a professional and technical environment.

“Ultimately, I believe this has helped me be successful in my role at Formulatrix, where I manage and work with teams of engineers based in Indonesia,” Wikholm said. After his work at Fraunhofer, he took another internship at Precision Combustion, Inc. in North Haven, Connecticut, where he assisted with preparing, performing, and analyzing experiments to evaluate new catalytic formulations.

Wikholm views all of these experiences as crucial for his success, and he believes the field of MSE is vital for the whole of engineering.

“I see the UConn MSE program as a hidden gem. It is a fundamental crux to almost any engineering field. It’s great for learning the essentials of engineering problem solving,” he said.

He recommends that other students interested in engineering consider becoming an MSE major.

“An MSE background can bring new perspectives to develop solutions for problems in other engineering fields,” Wikholm said.

Author: A Single Class Paved the Way for MSE Alumnus Ryan Noraas to Discover His Field of Study

By Ben Crnic

MSE Alumnus Ryan Noraas (2016)

During his time at UConn, MSE alumnus Ryan Noraas decided to take MSE 5310 DFT Materials Modeling, and became fascinated with predicting fundamental material properties using atomistic simulations. This budding interest carried him to the field of machine learning and artificial intelligence, and ultimately led him to his current projects in his position at Pratt & Whitney. He is currently a staff engineer in the Materials and Processes Engineering lab.

“Sometimes, all it takes is a single spark to help you find a field of study,” Noraas said.

At Pratt & Whitney, Noraas works with the United Technologies Research Center (UTRC) on projects related to machine learning algorithm development. He also focuses on materials modeling and quantification of process-microstructure-property relationships for jet engine applications, especially with titanium and nickel-based superalloys. He enjoys the teamwork that comes with the position, in addition to the flexibility to work in a wide variety of interesting projects.

“In general, most of our engineers are in a unique position to not only develop technology for the future, but also to support critical production and field issues as they arise. It’s an interesting work environment that always keeps you on your toes. It provides a unique opportunity to network and learn about many different materials systems,” Noraas said. 

Noraas cites UConn’s proximity to Pratt & Whitney as a reason for choosing the school to complete his master’s degree.

“Pratt & Whitney and UTC have a great working relationship with UConn, so it was a natural choice,” Noraas said. He graduated from UConn in 2016 with a Masters in MSE, and his advisor was MSE Department Head Bryan Huey

Similar to the way he discovered machine learning, Noraas can trace his introduction to MSE to a single experience that ignited his passion for the subject. During a high school field trip to Pennsylvania State University, he witnessed an experiment where two heat-treated ball bearings, one rapidly quenched and one cooled in a furnace, were dropped simultaneously on a solid surface. The furnace-cooled bearing bounced once or twice before coming to rest and produced a dull sound upon impact, while the quenched bearing bounced up and down like a rubber ball and produced a high pitched ring. The starkly different effects of heat treating provoked Noraas’s interest, and from that day on he knew he was to be an MSE major.

He encourages current MSE students to take a wide variety of classes with topics that may be unfamiliar to them, as they may find a new direction just as he did with machine learning through taking MSE 5310.

“One of my favorite quotes is ‘You don’t know what you don’t know.’ So strive to keep learning, and try new things–you may discover entire fields of study and opportunities that were ‘invisible’ or unknown to you at the time,” Noraas said. He also has some more specific, practical advice for MSE majors:

“Learn how to code. Materials engineers work with a ton of different types of data, so learning how to code and automate things with Python or Matlab will assuredly save you and your company a lot of time and money,” Noraas said.

 

Author: MSE Professor Inducted Into Young Academy

By Ben Crnic

MSE Assistant Professor Stefan Schaffoener with Ph.D. candidate Sharon Uwanyuze (left).

MSE assistant professor Stefan Schaffoener was recently inducted into the Young Academy, which was established by the Academy of Sciences and Literature | Mainz in Germany  to support promising young scientists as they pursue their careers. The academy seeks to assist young scholars in developing their scientific talent and expanding their scientific networks, as well as to promote dialogue across both disciplinary borders and generations.

Schaffoener is looking forward to working with people in disciplines outside of engineering on his future research projects.

“Because humanity has been involved with materials for a long time and MSE is a rapidly advancing field, we can connect it to a lot of other research that has a large impact on society,” Schaffoener said. He cited as one example of these connections how research into changes in geographic mobility overlaps with research on how changes in transportation affect greenhouse gas emissions, as well as the demand for certain enabling materials and other technologies, thereby bringing together investigators from a variety of fields.

Membership in the Young Academy is limited to a period of 4 years. Due to the COVID-19 pandemic the induction ceremony has been postponed to November.

On his hopes for the next 4 years, Schaffoener said, “I would like to do excellent research at UConn and work on projects that go beyond my field, which hopefully will improve the well-being of other people.”

Author: Congratulations to the 2020 MSE Senior Design Project Winners!

On May 1st, 13 teams of MSE seniors virtually presented their Senior Design Projects for the annual Senior Design Day. These capstone projects, each sponsored by industry, state, or federal grants, demonstrate the engineering skills students have learned throughout their undergraduate careers.

The ultimate aim of the grant is to strengthen UConn MSE’s relationships with the other participating universities, as well as to promote collaborative research and joint publications.

“I’m very excited because this grant gives us more opportunities to collaborate with experts from Norway, Germany and the United States. It also gives our students more perspective with their research and more opportunities to exchange ideas and research, as well as more opportunities to attract students to UConn,” Schaffoener said.

Schaffoener joined UConn MSE in the fall of 2018 after his postdoctoral fellowship at NTNU in Trondheim. He earned his doctorate in 2015 from TU Bergakademie Freiberg in Germany, a premier STEM university in Germany.

Author: MSE Graduate Student Reaches Out to Help High Schoolers Transition to College

By Ben Crnic

MSE graduate student Jessica Maita

After graduating from the Rochester Institute of Technology, Jessica Maita came to UConn as a master’s student in MSE. After her first year here, however, Maita was instead determined to pursue a Ph.D. She is now a doctoral student in MSE professor Seok-Woo Lee’s group, where her research focuses on the multi-scale microstructural characterization and mechanical properties of nanocrystalline magnesium aluminate ceramics, materials that are of special interest for transparent armor applications.

When she is not spending time on her research or serving as president of the UConn Materials Research Society (MRS) Chapter (https://mrs.engr.uconn.edu), Maita volunteers for outreach activities that assist high school students in the process of applying to college. These activities are conducted with the help of the UConn School of Engineering’s Bridge to the Doctorate (BD) Fellowship Program, which supports African American, Hispanic and/or Native American students pursuing graduate degrees in STEM.

As one example of her outreach efforts, Maita participated on a BD-organized graduate student panel that addressed low-income, underrepresented students in the Connecticut Collegiate Awareness and Preparation Program (ConnCap) Program at Danbury High School.

“Previously being in their position, I knew the students could benefit from advice we could provide. It is common for students from this background to feel pressured into specific career paths but we were able to provide information on the many career options they have as well as all the opportunities they should take advantage of while being an undergraduate student,” Maita said.

Awarded the Materials Research Society (MRS) 2019 Special Projects Grant, a group of UConn MRS members took a tour of the research facilities at Brookhaven National Laboratory in Upton, NY.

Maita believes that it is crucial to reach high school students before they move on to college.

“Though I am a strong supporter of the programs available at the university level, I believe support needs to be provided sooner. The earlier you can reach students the sooner they can prepare for success,” Maita said.

Her background makes her sympathize with students who may be in a position similar to the one she was once in, and it motivates her to participate in these outreach activities.

“I know how it feels to have to go through the college experience with very limited help from your family. Their minimal English and elementary level education made it difficult for my parents to help me, whether that be financial or emotional help. I want to provide the information students need to be successful, so that they can take advantage of the opportunities I didn’t know about,” Maita said.

Maita herself received The National Science Foundation Louis Stokes Alliance for Minority Participation (LSAMP) BD Fellowship award.

“This fellowship made it possible for me to pursue my graduate degree without the financial burden I was originally going to shoulder,” Maita said.

After joining MSE, Maita formed a close bond with other BD fellows.

“Not only did I receive financial support but I also gained a family at UConn. All current BD fellows meet on a biweekly basis to discuss our professional and personal development. BD provided a group of friends that are experiencing similar issues as me and which I know I can turn to when I need help,” Maita said.

Maita plans to continue with her outreach activities in the future.

“When an opportunity presents itself, I make an effort to help,” she said. Ultimately, after completing her Ph.D., Maita would like to work in industry.

Professor Lee wants other MSE students to learn from her example.

“Jessica is a truly wonderful student who takes care of others a lot. She has already made a significant contribution to outreach as well as university-level service more than any other student I know. I hope that many students will look to Jessica as their role model and follow Jessica’s career path. I really appreciate her considerate leadership.”

Author: Professor Hebert Leads Successful Research Collaboration Between UConn MSE and Industry

By Ben Crnic

Rainer Hebert, MSE Associate Professor; Castleman Professor in Engineering Innovation; Director of Additive Manufacturing Innovation Center; Associate Director of the Institute of Materials Science (IMS)

MSE professor Rainer Hebert recently led a study in collaboration with the Collins Aerospace Center for Advanced Materials at the UConn Tech Park. Collaborating partners also included Pratt & Whitney, Schlumberger Reservoir Completions Technology Center, and UTC Additive Manufacturing Center of Excellence. The study, entitled “Novel Al-X alloys with improved hardness,” centers on high-strength aluminum-based materials for use in 3-D printing, an additive manufacturing process. 

This research is of strong interest to the aerospace industry because materials such as aluminum that are light and strong are used to manufacture small aircraft parts with complex geometries that are difficult to produce with traditional manufacturing.

“Working with Collins and Pratt & Whitney helped us remain focused on the end goal of aerospace applications, and their input is invaluable for bridging the gap from fundamental research to applications,” Hebert said.

The Collins Aerospace Center, established in 2016 and directed by MSE professor Pamir Alpay, is the result of continuing collaboration between UConn and Collins Aerospace, one of the world’s largest suppliers of technologically advanced aerospace and defense products. The center offers funding for studies that focus on areas related to materials development and characterization. It also provides an opportunity for firsthand interactions with an industrial partner whose technologies are used in advanced aerospace and defense applications.

This study is one of several related to 3-D printing that UConn MSE has conducted with the help of the Collins Center. Hebert expects that more collaborations will occur.

“We will continue on this trajectory and have new initiatives underway to collaborate with industry,” Hebert said.

Nakhmanson that has become one of the top 100 most downloaded papers on physics published in 2019, according to a list compiled by Scientific Reports. The paper is entitled “Electronic and Magnetic Properties of Lanthanum and Strontium Doped Bismuth Ferrite: A First-Principles Study.”

The study focuses on using first-principles theory to investigate the effect of A-site dopant (lanthanum and strontium) on the changes in the electronic and magnetic properties of bismuth ferrite (BFO), which is a well-studied multiferroic material. The correlation between these properties of transition-metal oxide materials such as BFO has many technological applications, including tunable multifunctional spintronics, magnetoelectric random access memory devices, and various kinds of electronic sensors and optoelectronic devices. Since BFO thin films exhibit low electrical resistivity which limits its application in designing novel multifunctional non-volatile random access memory devices, the research featured in the paper contributes towards understanding how dopants like lanthanum and strontium can help overcome these shortcomings.

The research was performed in collaboration with Honchul Choi and Jian-Xin Zhu, both scientists from the Theoretical Division of Los Alamos National Laboratory (LANL). This collaboration grew from a mutual interest in working on a perovskite material such as BFO, as well as Ghosh’s visits to LANL in 2017 when she was hired as a graduate research intern. Both Ghosh and Trujillo are currently also working on other projects and publications together.

On being a part of one of the top 100 most downloaded papers on physics, Ghosh said, “It is good to know that this paper is well-received by the research community and gaining attention. It will be great to see a few extensions of this research in the future as well.”

Trujillo said, “It was amazing to be recognized for our work and to see that people were interested in our research. It validates the hopes we have from the beginning of any project that our work will be well received and have some impact on the community.”

“Both Professor Nakhmanson and I have enjoyed working on this project with Ayana and Dennis who have done a great job with the calculations, the analysis, and the presentations of the results,” Alpay said.

Author: MSE’s Metalworking Club Offers a Unique Experience for MSE Students

Author: MSE Professor’s Research is More Than What Meets the Eye

By Ben Crnic

Dr. Seok-Woo Lee and Gyuho Song (5th year Ph.D. student) conduct an in-situ micro-mechanical measurement.

Many of the materials that UConn MSE Assistant Professor Seok-Woo Lee works with in his research are invisible to the naked eye. In order to even see them, an electron microscope is required. Some samples are more than 100 times thinner than a human hair. Despite this, the nanomaterials that Lee researches are crucial to producing mechanically robust devices and structures.

According to Lee, creating resilient small materials is important for smaller machines.

“In order to develop a mechanically reliable robot or machine at the nano-/micro-meter scale, we need to know how to create a strong and tough ‘small’ material,” Lee said. His research group is working on understanding how characteristics of materials can influence mechanical behaviors of substances including metals, ceramics, intermetallic compounds, and polymers.

One such way to control mechanical behavior is reducing the size of materials. As a material’s size decreases from macro to nano-/micro-meter scales, it usually becomes much stronger and tougher. However, this can change as temperatures become more extreme. Part of Lee’s research involves exposing micromaterials such as metals to very cold temperatures, where they become brittle and fracture easily. Lee is attempting to find a way to avoid this. 

It is important to understand how materials may respond in extremely cold environments for applications such as the vacuum of space. One example is called a cryogenic shape memory material, which can recover its original shape even after being largely deformed. The process of recovering its shape by expanding or contracting can be used to create mechanical motion.

“This long-range motion can turn on an electrical switch for a cold, dormant satellite in deep space once it meets a heat source such as a star. Also, this material can be used to move a mechanical component to control a robotic arm or telescope lens that is used under cold environments such as the shadow area of the moon,” Lee said.

Although Lee is dedicated to his research, he mainly sees himself as a teacher.

“Teaching is very important to me because I have always believed that I am basically a teacher. Once a student receives a good lecture, they can remember what they learn for a longer time,” Lee said.

Lee has received multiple awards for his teaching, including the UConn Mentorship Excellence Award in 2019 and UConn MSE Teaching Excellence of the year in 2017 and 2018. Lee is proud of being recognized for educating.

Lee has both undergraduate and graduate students, and over time, he has learned that they both require different approaches. According to him, the major difference is independence when it comes to performing research.

“A graduate student can design and perform experiments by themselves. However, I usually assign a simple and relatively straightforward research topic to undergraduate students because they are very busy due to their classes. I usually give step-by-step instructions to an undergraduate student, then they can learn the details of the research even without much prior experience,” said Lee. The graduate students Lee works with handle the microscopic material that he researches and are able to “pull and push a sample with an extremely precise control of force,” Lee said. An electron microscope has to be used in order to see these samples, as they are too small to be visible in a regular optical microscope.

According to Lee, it is fun for him to work with the three undergraduates and five graduate students who are part of his research group. He feels his MSE students should be especially proud of their major.

“I want to tell our MSE students that their decision to study MSE is a great choice. More and more I see that technological breakthroughs require the development of new advanced materials. Creating high-performance engineering devices such as micro-processors, airplanes, satellites, etc. requires sophisticated materials design and processing. Because of this, studying MSE becomes more important in overcoming our technological limits. So, I really think they should be proud to be MSE majors,” Lee said.

In addition to his work with students, Lee also collaborates with other faculty members on research. One such project is a cold spray project for the US Army, which he is working on with MSE professors Avinash Dongare, Mark Aindow, and Harold Brody. Lee enjoys these collaborations, which helped influence his decision to come to UConn.

“I chose UConn because of great people here. All of the faculty and students I met during the interview were very nice and friendly to me. I always believe that working with wonderful people is very important, and I thought (and still think) that those people are here at UConn,” said Lee. 

Lee discovered materials science when he was in high school. He always wanted to combine his love of physics and chemistry with “making something useful,” which was fulfilled by materials science and engineering.

“I found that materials science and engineering is the best program because I can do both science and engineering! Also, I always wondered how matter was formed after the beginning of the universe, and I thought that it would be wonderful if I could design and create a special matter under my own control,” Lee said.

This interest followed Lee to his current career, and he is optimistic about his students also being a part of the MSE field.

“They can use this knowledge of materials to improve our world,” Lee said.

Author: An MSE Undergrad’s Interest in Corrosion Led Him to the Perfect Research Project

By Ben Crnic

MSE Senior Alex Perkins pictured with the simulated seawater baths used in his research project. Steel coupons are placed in the water baths and corroded.

When UConn MSE undergraduate student Alexander Perkins was in the spring semester of his junior year, he noticed he had some free time in his schedule. He decided to fill this open spot by joining a research project. This led him to MSE Assistant Professor Lesley Frame, and a corrosion research project that caught his attention. Perkins, now a senior, is working on predicting material loss rates for active corrosion on bridges.

According to Perkins, the main goal is to identify corrosion products as a function of environment and time for different steel compositions and with different protective coatings. Frame’s group is looking at specific corrosion products and characterizing them in order to understand the material loss rates better. They are collaborating with CEE assistant professor Arash E. Zaghi and MSE Associate Professor Serge Nakhmanson’s research groups on aspects of this project.

“This project will help us understand how to better protect against corrosion of the steel that is used in bridges and how that corrosion impacts the lifetime of the bridge,” Perkins said. 

Perkins’ specific role in the project is preparing samples for corrosion tests, as well as planning the designs of the experiments for these tests.

Because corrosion is something that is often commonplace, it is Perkins’s main research interest.

“It’s something you see every day, so I want to know more about it and what causes it,” Perkins said.

This fascination was influenced by his MSE classes. Perkins’s favorite class so far has been MSE 3020 Failure Analysis, which he took with MSE alumni (Ph.D. ’02) and Adjunct Professor Daniel Goberman. Corrosion, in addition to being widespread, is a common cause of failure in materials. This makes Frame’s project a perfect fit for Perkins’ academic interests.

Perkins became interested in materials science right before he arrived at UConn. While he was in high school, he attended an open house and talked to one of the students at the MSE booth. The demonstrations at the booth caught his attention and MSE seemed more interesting to him than other forms of engineering. 

Now towards the end of his undergraduate career, Perkins is starting to look towards the future. After graduation, he plans to enter either the medical device or aerospace industries.

For MSE students who want to start researching but do not know where to begin, Perkins has some straightforward advice. 

“Just go talk to any professor who you think you’d like to do research with. All the professors in MSE are really approachable and support undergraduate research in their labs. If their lab doesn’t end up being a good fit they can recommend another professor to talk to,” Perkins said.

Two MSE students, Ayana Ghosh and Lucas Enright, won awards at the 11th annual Electronic Materials and Applications (EMA) Conference. The conference was organized by Electronics and Basic Science Divisions of the American Ceramic Society and was held in Orlando, FL at the end of January 2020. Ghosh, a graduate student, was awarded Best Poster for her research on organic ferroelectrics, and Enright, a senior, was recognized as the Best Student Speaker for his talk in the session devoted to 5G telecommunications.

Both Ghosh and Enright attended the conference as part of a larger group of UConn MSE students, and were accompanied by MSE faculty including Associate Professor Serge M. Nakhmanson (Ghosh’s Ph.D. advisor) and MSE Department Head Bryan Huey.

Ghosh’s winning poster was dedicated to designing novel organic ferroelectrics. Her research focuses on understanding the mechanisms governing the emergence of ferroelectricity in these materials. She uses machine learning and data-driven approaches both to search for potential novel organic ferroelectrics and to establish design principles for achieving new functionalities.

“I try my best to understand what type of information is the most important/suitable to share during poster presentations that would engage the listeners and stir interest surrounding my research,” said Ghosh.

Meanwhile, Enright’s award-winning talk was on a project he conducted on the measurement of dielectric properties of ceramics at low-millimeter (W-band) frequencies. Originally, his research investigated heating in these materials occurring during the absorption of millimeter waves, but the focus was later shifted to applications in 5G technologies.

Enright’s research was conducted in collaboration with the Air Force Research Laboratory’s (AFRL) Directed Energy Directorate in Albuquerque, New Mexico, where he was an intern during the summer of 2019.

On winning the Best Student Speaker Award, Enright says “I am honored and flattered. It is really touching to be so well accepted by what seems to be a close-knit technical community who have been extremely welcoming and helpful.”

Associate Professor Nakhmanson says “I am delighted by how well our students represent UConn and the MSE department at the annual EMA conferences, which are increasingly becoming a premier international venue for cutting-edge research in ceramics. We go to that conference in numbers pretty much every year and have been fortunate to receive some awards before. However, I consider this visit especially successful, bringing home the best poster award, as well as a special award received by an undergraduate student. This sort of peer recognition clearly shows that UConn MSE is a good place to get your graduate or undergraduate degree in materials science.”

Author: How Working with NASA Led Theresa Nosel to Major in MSE

By Ben Crnic

MSE Sophomore Theresa Nosel has had two internships with NASA

Before even coming to UConn, MSE sophomore Theresa Nosel was already very much accomplished. After all, she had two internships with NASA under her belt before transferring to the university from Manchester Community College (MCC) for her sophomore year, an achievement that anyone would consider impressive. Ultimately, she put the experience she gained with NASA to good use, as these internships set her on a path to majoring in MSE.

Nosel was able to get her first internship with the help of a program called the NASA Community College Aerospace Scholars program. Even though this was an online program, Nosel was able to go on-site in Virginia, to the NASA Langley Research Center, and then to the NASA Wallops Flight Facility, for a week each as a continuation of the online program. At the latter facility, she met an employee from the NASA Stennis Space Center in Mississippi who was helping with the program. Nosel applied to be an intern there for the spring 2019 semester, and was accepted.

During this internship, Nosel worked in the Office of Education, where she would speak to the community about STEM and the different programs NASA has available for students.

In her summer 2019 internship at NASA, Nosel delved more deeply into research and was first exposed to materials science. In an organic chemistry laboratory at the Glenn Research Center in Ohio, her research focused on making a material called polyimide aerogels and their use  in  additive manufacturing processes.

“To be honest, materials were never something I thought I would be interested in, but then I worked with aerogels and I got a small taste of the incredible things that can be done with materials,” Nosel said.

After her internship at Glenn, Nosel transferred to UConn from MCC, where she was originally a chemical engineering major. However, after her experience researching aerogels, she was interested in adding a minor in MSE at UConn. She managed to change her schedule so that she could fit in an introductory course, MSE 2001 (Introduction to Structure, Properties, and Processing of Materials I), which was taught by MSE assistant professor Yuanyuan Zhu. As her first semester at UConn went on, she realized more and more that she wanted to work with materials as well as chemical engineering, and become a double major.

“The MSE class was very interesting and my professor was wonderful, and the more I looked into the applications of materials science, the more I wanted to learn,” Nosel said.

Last month Nosel became an MSE major. She thinks her internship programs prior to UConn prepared her for her MSE classes. 

“I went back to Glenn over the winter break to continue research for a few weeks, and going back I felt more confident in what I was doing than before. I knew a lot more about the fundamentals with what was happening in my research than over the summer because of the classes I had taken during the fall semester,” Nosel said.

As for now, Nosel is not currently involved in any research at UConn but hopes this will change soon.

 “I think being an undergrad is an excellent time to really explore as many options for research as possible so as to make the most informed decisions on what you want to do afterwards,” Nosel said. 

When it comes to her plans beyond her undergraduate career, she expects to pursue a doctorate degree, although she still has to decide her preferred field of study. Currently, she is interested in polymer science.

In addition to inspiring her choice of major, Nosel’s internships have influenced her possible career choice as well, as she would be interested in continuing her work at NASA.

“I really enjoy everything I have done at NASA and would be very happy if I could continue that,” Nosel said. “In the end, I want to do research and advance science in terms of exploration and sustainability.”

From her experiences at NASA, Nosel has also gained some valuable lessons.  She encourages other students to seek out opportunities that they might be interested in, and go for them when they find them, even if they have doubts.

“When I first applied to NASA (and actually every time I have applied for something with NASA) I had every doubt in the world. I never imagined I would be accepted, and I actively prepared myself for the rejection I thought was inevitable. I am still in shock with the opportunities I’ve been lucky to have been given with NASA, and it is all because I pressed that ‘submit’ button.”

Author: Lesley Frame Voted Vice President of Heat Treat Society

By Ben Crnic

Lesley Frame

Assistant Professor Lesley Frame, Ph.D.

MSE Assistant Professor Lesley Frame was recently voted Vice President of the Heat Treat Society (HTS). HTS is a professional organization that serves members who specialize in thermal processing, whereby metals, ceramics, and other materials are heated and cooled to improve their performance and durability. HTS is an affiliate society of ASM International, one of the largest associations of materials engineers and materials scientists in the world.

According to the November/December issue of Advanced Materials and Processes (AM&P), an ASM International publication, Frame is the first woman in an HTS Officer role. Frame is also the immediate past chair of the HTS Technology and Programming Committee and current chair of ASM’s Women in Materials Engineering Committee. 

As Department Head Bryan Huey notes, “Lesley’s election is another great example of UConn MSE faculty being recognized by their professional peers for their leadership and expertise.”

Four students represented UConn MSE in the Fluxtrol Student Research Competition at Heat Treat 19, an event in Detroit organized by the Heat Treat Society (HTS) Technology and Programming Committee. Seniors Indranie Rambarran, Kevin Sala, and Cameron Sanders, as well as 2nd year Ph.D. student Kevin Zhang, each presented posters of their research to international professionals in thermal processing from both academia and industry.

Indranie Rambarran, MSE Senior, presents her research poster in the Fluxtrol Student Research Competition at Heat Treat 19.

Indranie Rambarran was one of six students selected by the panel of judges for the semi-finalist round of the competition, and one of only 2 undergraduates who made it this far from the entire nationwide field. In her ensuing oral presentation, Rambarran presented research she is conducting with her advisor Lesley Frame. They are focusing on examining residual stresses in a Titanium alloy (Ti 6Al-4V) following heat treating and machining. It is crucial to understand such stresses especially because such titanium alloys are widely used by the aerospace industry. Undesirable residual stresses can result in premature failure of critical parts. “Residual stresses are notoriously difficult to measure accurately, and Indranie’s hard work over the summer allowed her to identify ways to reliably measure these stresses in the experimental samples,” says Frame.

Her presentation focused on comparing two methods of characterizing the residual stresses. Rambarran first spent a summer collecting X-ray diffraction measurements on the Rigaku SmartLab at the UConn Tech Park. She then spent the fall 2019 semester collecting measurements with a Pulstec X360s X-ray analyzer. The Rigaku used the sin2ψmethod, while the X-ray analyzer used the cos α method. She then compared the two approaches to determine which one measured stresses most effectively.

Rambarran discovered that the cos α method allowed more accurate measurements of residual stresses in the titanium samples than the sin2ψ method. This is partially because it takes the texture of the material microstructure into account.

“I would personally like to thank Dr. Frame because without her, none of this would have been possible! Although I did not win the final prize, making it as far as I did was enough for me to know my research meant a great deal,” Rambarran said.

“I am thrilled that UConn made such a good showing at Heat Treat 2019 and I am very proud of Indranie. She was up against Ph.D. students presenting their dissertation research and she did very well in the final presentation round,” says Frame.

Author: MSE Undergraduate Interns at Oakridge National Lab

By Ben Crnic

UConn MSE Sophomore Ryan Gordon

MSE sophomore, Ryan Gordon, has been offered a competitive summer internship at Oakridge National Lab in Tennessee as part of the Science Undergraduate Laboratory Internships (SULI) Program. As an intern, Gordon will be conducting research on the use of molten salts as coolants for nuclear power plants. Specifically, he will investigate the corrosive properties of these salts.

The SULI program offers undergraduate students 10-week summer internships at one of 17 participating laboratories. Students select their preferences for laboratory assignments when they apply to the program. Once they are accepted, they are assigned to a mentor at the lab they are sent to. Since the program is offered to undergraduates, students without extensive prior research experience can still obtain internships.

Gordon will be performing his research alongside Dr. Stephen Raiman and his team. As part of his internship, he will be presenting his work at Oakridge National Lab in front of other SULI participants. His internship culminates with a final written laboratory report detailing his findings.

 “I would just really like to thank Dr. Lesley Frame. She was able to offer me research last year as a freshman with absolutely zero experience. Because of the opportunity she gave me, I was able to learn a tremendous amount and really grow as a student. If it was not for this research position, I never would have been able to get this outstanding internship, and I am extremely grateful,” said Gordon.

Author: How a Materials Scientist Steps Out Of His Comfort Zone by Conducting Diverse Research Projects In a User Facility at NCSU

By Ben Crnic

Chung with one of the three X-ray diffractometers at AIF

Ching-Chang (“BB”) Chung, a 2014 alumnus of UConn’s doctoral program in Materials Science and Engineering (MSE), recently became a laboratory manager at North Carolina State University (NCSU) in the Analytical Instrumentation Facility (AIF). As lab manager, Dr. Chung manages X-ray diffraction (XRD) and micro/nano-CT laboratories. He also trains students on the instruments in the lab and assists them with their research, allowing him to work on a wide variety of materials with researchers from diverse fields.

Since Chung is exposed to a wide array of research topics, he constantly learns about new materials. Since becoming lab manager, he has worked with materials ranging from semiconductor thin films to insects.

“On a lucky day, I could be characterizing the crystallinity of polymer fibers in the morning and working on CT imaging of a dinosaur fossil in the afternoon,” said Chung.

Dr. Chung notes that transitioning from researcher to lab manager certainly had its challenges. Because he is often involved in fields that are completely outside his background, Chung struggled at first with tackling problems in areas of materials research with which he was unfamiliar.

“In the beginning it was very challenging, but with the accumulation of experience, I have become more confident with different materials,” he said.

Chung also enjoys the networking opportunities that his exposure to a diverse range of research projects affords him. He collaborates with researchers from across the globe, many of whom he now regards as friends.

Chung describes his work as “a perfect way to build a strong international network.”

As lab manager, Chung doesn’t only learn about new materials. He also teaches researchers about how to work with their materials.

“It is fairly important to help people, especially those without an engineering background, to understand the principles of XRD and micro-CT, the limits of their materials and what their data means, etc.” said Chung.

Of course, explaining the theoretical underpinnings of XRD and micro-CT to those with no materials science and engineering background is no easy task. Since only a certain number of researchers who use his lab have such background, Chung is constantly trying to improve the way he explains the applications of these techniques.

Chung typically spends half of his day in the laboratory interacting with researchers and explaining to them how to use the XRD equipment. He also helps them design their experiments and perform measurements, and even assists them in interpreting their results. He devotes the rest of his time to his own research and collaborative projects.  Much of this research focuses on functional oxides, especially ferroelectrics. Eventually though, Chung wants to shift about 50 percent of his research to the applications of XRD and micro-CT analytical methods to other materials.

During his time at UConn as a graduate student, Chung’s research also focused on ferroelectrics, but he also had a passion for materials characterization. Since UConn’s MSE faculty are well known for their research on both ferroelectrics and analytical materials characterization techniques, UConn was a natural fit for Chung when the time came to select a graduate school. He ultimately chose UConn because of the active research environment, as well as because of its beautiful campus.

Chung believes that he learned many important skills at UConn.

 “Aside from the knowledge and technical skills I obtained during my Ph.D. training, the most important transferable skills that I gained that helped me transition to the real world were critical thinking and problem solving,” Chung said.

He also benefited from his experiences as a teaching assistant. Indeed, teaching is an important aspect of his duties in his current position.

Chung still keeps in touch with his UConn mentors, especially his dissertation advisor, MSE Associate Department Head George Rossetti

 “So many years after, we still keep in close contact with each other and continue to collaborate on research projects,” said Chung.

After graduating from UConn, Chung joined the research group of Professor Jacob Jones , who directs the AIF at NCSU, and was one of Rossetti’s research collaborators at the time.

“BB’s doctoral dissertation research work was especially challenging, involving ceramic processing, analytical characterization, electrical property measurements and the phenomenological theory of ferroelectric materials,” said Rossetti.  “Given that BB excelled in each of these areas, it was no surprise that he was immediately snapped up for a post-doctoral position in Professor Jones’ group at NCSU.”

At first, Chung spent half of his time as a postdoc in Jones’s lab, and the other half at AIF managing the lab. Working with Jones exposed Chung to a wide range of research projects and expanded his professional network.

Chung’s decision to stay at NCSU was motivated by the school’s research opportunities. NCSU has an excellent School of Engineering and research there is only expected to grow. Yet, Chung still looks back fondly on his days at UConn. He even has advice for future students:

“Find out what you want to do with your MS/Ph.D. degree early on at graduate school and have a plan in mind as to how to get there.”

Chung also believes that students should take advantage of the many resources UConn provides and attend career fairs to make important connections.

“Reach out to alumni, network and talk to people that hold positions that you might be interested in, ask about their career pathways,” Chung said.

As for the future, Chung wants to stay involved in many different research projects and to continue learning new characterization techniques.

“Working with broad research topics will push me out of my comfort zone and diversify my knowledge and analytical skill set.”

He doesn’t have a specific position at NCSU that he is working towards.

“Rather than aiming for a job title that sounds impressive, I am more interested in the science itself,” said Chung.

As a sports fan looking for a college major, Ryan Keech became interested in the design and processing of football helmets and baseball bats in high school. Materials Science and Engineering (MSE) stood out as the right profession for developing improved materials for sporting goods. Then, Ryan learned that UConn has an MSE program, and applied. He completed his bachelor’s degree at UConn in 2011 and received his Ph.D. in Materials Science and Engineering from Penn State University in 2016. Today, he works on developing new materials for Intel, a leading technology corporation.

As a Module Integration and Device Yield Engineer at Intel’s Portland Technology Development campus in Oregon, Ryan works in a state-of-the-art nanofabrication facility developing new materials to “optimize transistor device performance.” With new materials and processing techniques showing performance improvements, he then has to ensure they be manufactured in high volume. Though he’s far from his original goal of developing new materials for sporting goods, Ryan has found his true passion.

“It has been most exciting to me to work at the leading edge of science and technology. I work with other experts in various fields across electrical engineering, materials science, and materials characterization to extract as much data and learning as possible from an experiment to position our team for success in our program goals.” Ryan and his teams at Intel have already received numerous U.S. patents and filed invention disclosures for the materials and devices at the core of the processor chip technologies used today for communication, travel, and medicine.

“Learning the fundamentals through undergraduate study at UConn MSE was necessary to be prepared for professional work, but there was much more afforded to me and my classmates in the MSE program,” Ryan said.

UConn MSE alumnus Ryan Keech, Ph.D.

When Ryan first learned that UConn, his preferred school, had an MSE program, he immediately applied. Then, after hearing Professor Bryan Huey present about the field in his freshmen Intro to Engineering course, he knew he chose the right major.

“I just loved the campus, the sports programs, and opportunities which UConn offered. Once I found my interest in MSE, UConn was the clear and perfect fit for me,” he said.

While Associate Professor Rainer Hebert was his advisor, Ryan built relationships with all of his professors. One thing he liked about the program was that professors designed open-ended assignments with real world applications and opportunities for team work.

“Professor Brody taught me how to be an engineer – how to solve a problem when you don’t have all of the information given to you. Professor Alpay and Professor Hebert challenged us to define our own problem statements (and find their solutions) from general, open ended questions. Professor Huey encouraged thinking outside the box to link various methods of problem solving together,” Ryan said.

Overall, Ryan and his classmates learned the materials processing and characterization techniques that are the foundation of their field.

But even with such thorough preparation for the professional world, there was a learning curve at Intel.

“At a major company like Intel, there is emphasis on collecting and sharing data and ideas as quickly as possible,” Ryan explained. There are many acronyms and project-specific terminologies used to accelerate experimental planning and interpretation, which can be confusing for new hires. “But overtime you become fluent in the new shorthand language just like the rest of your colleagues,” Ryan said.

One practical outcome of Ryan’s work is improving clock speed, drive current, and power consumption for chip architects at Intel to have the “best materials and transistors available as building blocks” for their computer processors. “Those chips deliver new capability to innumerous technological efforts around the world,” Ryan said.

His time at UConn was filled with countless memories from the lifelong friendships he made. Perhaps the most valuable thing Ryan learned as a student in UConn’s MSE program was learning to ask “why,” and then finding a way to answer that himself.

“The loop of questioning what I thought I knew and then proving it to myself helped me understand the classroom lessons from different perspectives. The sooner a student starts down that path, I think the more success they’ll have,” Ryan said.

Abhinav’s cover image shows the reactive spray deposition technology (RSDT) process he used to synthesize Pt-free electrocatalysts described in his research article.

Congratulations to recent MSE graduate Abhinav Poozhikunnath, Ph.D! Just five days after defending his dissertation, his work was selected by Journal of Materials Science for publication as the cover article for the print issue to appear in February 2020.

The journal cover shows the reactive spray deposition technology (RSDT) process Abhinav used to synthesize Pt-free electrocatalysts described in his research article titled “Characterization and evaluation of Fe–N–C electrocatalysts for oxygen reduction directly synthesized by reactive spray deposition technology.” The article has already been published online.

“There is no greater joy for me than to see my students doing well,” his advisor and Vice President for Research, Innovation, and Entrepreneurship, Radenka Maric, said in an email. “Seeing the cover page of the journal with our equipment and the flame spray process, one we built from scratch with my students in the Center for Clean Energy Engineering, I cannot express how grateful I am to Leonard Bonville for keeping our students safe and teaching them the best engineering practices while I am serving as a VPR.”

“Talk about perfect timing,” Abhinav wrote when he shared the news on LinkedIn. “This cover picture represents the culmination of 5 years of research at UConn as part of the Maric research group! It has been a thrill working with Radenka Maric, Leonard Bonville and the team. Now, it’s time for me to start the next phase of my career!”

Author: Why the Honors Program was ‘Worth the Challenge’ for Andrew Levin

By Amanda Song

Andrew Levin wanted to research technologies that could combat climate change. Majoring in Materials Science and Engineering united his interests in nature and technology. Joining the honors program provided him with an opportunity to build on those interests. Now, he’s investigating materials for renewable energy.

As a seventh semester senior in the honors program, Andrew has had research and internship experiences that helped him to narrow his interests in materials science and engineering (MSE), and to advance his career goals. One thing he wants students to know about the honors program is that it “better prepares you for the future.”

The honors program has helped Andrew transition from a student who consumes information, to one who acquires knowledge as an aspiring research scientist.  He is now pursuing graduate study and applying to Ph.D. programs. His long-term career goal is to use advanced materials characterization techniques to improve solar cells, batteries, fuel cells, and thermal energy devices that can enable more sustainable sources of energy. 

Andrew uses a glove box and spin coater to fabricate thin film perovskite samples.

“Nature has always inspired awe in me, and I want to do all that I can to both understand and protect it. Materials science and engineering allows me to study the physics, chemistry, and fundamental sciences of what controls materials, and to apply the fundamental science to solve real-world problems.”

Andrew entered the honors program when he was admitted to UConn. However, rising sophomore and junior students can also apply to join the program, which provides research, funding, and other enrichment opportunities that enhance the student experience. 

Participation in the honors program comes with challenges. “It has been a good challenge being an MSE honors student. Each semester, one MSE course is designated as an honors course, and I have to complete an honors thesis,” Andrew said. 

Nevertheless, the work is rewarding. Andrew has become more confident in his understanding of MSE concepts. “Honors classes generally involve some sort of long-term project that builds upon course material. The projects have consistently improved my understanding and knowledge over course material,” he said. For his honors thesis, he chose to write a comprehensive research paper. “It required hard work and was very beneficial in bettering my technical writing skills.”

“Andrew is one of the most self-motivated students I have ever seen,” said his advisor, Assistant Professor Seok-Woo Lee. “He knows what he needs to do for his career. I hope that he becomes a leader who contributes to the development of new renewable energy materials and leads advances in energy technologies.”

The summer after his junior year, Andrew completed an internship at the National Renewable Energy Laboratory (NREL) in Golden, Colorado. As part of the Science Undergraduate Laboratory Internship (SULI) program, funded by the U.S. Department of Energy (DOE), students are paired with scientists at a DOE laboratory to guide them through a research project related to the students’ interests. Andrew worked with a mentor to research perovskites, a class of materials that are of intense interest due to unique properties that make them suitable for applications in solar cells, light-emitting diodes, and other electronic devices.

“I gained experience working with a wide range of advanced fabrication and characterization techniques. A research environment such as a national lab promotes constant learning, through discussion with fellow scientists and a constant spreading of knowledge,” he said.

The DOE internship, as well as other unique experiences Andrew had as an MSE honors student, really helped him to focus on his future career goals.  Going into the MSE honors program, Andrew struggled to clearly define his goals for combatting climate change, and to find ways to achieve them. But after taking honors classes and completing challenging research, he began to see that graduate school is one way to get there.   

“The UConn MSE environment has made me confident and directed in my career goals. I feel that my foundational knowledge in MSE is strong and that I will be ready for the more advanced coursework in graduate school,” he said.

Currently, Andrew, a Holster Scholar, is drawn to working with renewable energy materials and technologies, including solar cells, fuel cells, and thermal systems. “I am enticed by the mysteries of energy materials and their future potential. I aim to complete a Ph.D. in materials science, concentrating in advanced characterization techniques,” he said.

For students considering the honors program, Andrew added: “It is a challenge but it is well worth it. It will be stressful at times, but in the long-term your learning experience is enriched and you are better prepared for future challenges.”

Author: How One Student’s Bladesmithing Hobby Launched a Metalworking Club with over 200 Members


By Amanda Song

Two hundred years ago, one could find a blacksmith in every town or village in America. Handcrafting metal objects, from cooking utensils and candle holders to nails and weapons, was the only way to supply these commodities. Today, machines manufacture most of these products. Shows like Forged in Fire and YouTubers who provide tips and tricks about metalworking stoke the lingering interest in this craft for most. Nevertheless, blacksmithing remains a niche hobby.

Sam built a homemade forge using an old grill and some tricks he learned from the MSE program, and from YouTube.

Sam built a homemade forge using an old grill and some tricks he learned from the MSE program, and from YouTube.

However, one student at UConn is trying to expand interest in the historic trade. UConn Materials Science and Engineering undergraduate Sam Bedard launched the Metalworking Club this year to teach people about the craft of blacksmithing and casting in an environment where they can get hands-on experience, and learn about MSE at the same time.

“People within and outside of MSE are thinking about blacksmithing again,” Sam said. “It’s rewarding to work with your hands and make something, and I think this is part of the overall maker movement.”

With the help of Assistant Professor Lesley Frame, who has experience with metals processing and manufacturing, Sam started the Metalworking Club (also known as the Blacksmithing Club) in spring 2019. “It has been wonderful working with Sam on this club.  He is so motivated about blacksmithing.  All I do is provide the conduit for access to department and other University resources and Sam does just about everything else!” says Frame.  This semester, they have over 200 interested students and 50 active students in majors as diverse as business and CLAS. It has been necessary to limit club activities and projects to small groups of students at any given evening meeting due to space constraints in the MSE Foundry – where the blacksmithing and casting activities take place.  As the student interest grows, the Club has been working with the MSE department to find creative ways to expand to accommodate more students.   

Sam, a former environmental science and English double major, became interested in blacksmithing around the same time he switched to an MSE major. He realized he wanted to major in something more hands-on, where he could see the products of his work. He got a research position in Professor Mark Aindow’s lab and learned more about metalworking, then enrolled in a summer class.  “I set up my own tools and equipment from watching YouTube videos and started making tools and knives on my own,” he said.

However, blacksmithing requires a specific set of tools, and these days, things like anvils are a lot harder to come by.

“Getting an anvil is extremely expensive because most of them were melted down for steel production during World War II,” Sam said. “Now they sell for $500 each.” Theirs cost $450 and weighs 150 lbs. Sam invested his own resources the first semester, but the cost did not stop Sam from putting together a makeshift forge in his own backyard to practice at home.

With more than 40 active members in the Metal Working Club, students are split up during meetings. Here, a group of students heat and hammer a bottle opener into shape.

“A charcoal forge is a lot easier to set up than a propane forge,” Sam said. He began with an old grill he had at home. He cut an opening so he could drill a steel tube inside and use it for the central unit airflow. Then he added insulation and refractory cement to withstand the high heat it takes to forge steel. “I ordered some items from Amazon, and got the rest from home,” he said.

On campus, they build and borrow equipment for projects.  In fact, prior to purchasing a propane forge, Sam and the Club members built their own forge from scrap pieces and a propane burner. Professor Hal Brody has worked with the students to provide access to the MSE foundry, and even critiques of their work. Because of the high-interest from students, they usually need to divide group members during meetings: one group works on heat treating, one does metalworking. In addition, they hope to collaborate with the School of Fine Arts to borrow their ceramic heater. While waiting for funding approval from the Undergraduate Student Government (USG), the MSE department has provided funding for startup items like the anvil and a propane forge, and Sam is providing tools from his own resources.

“Once I’d been doing that for a while, showing lab mates, friends and family my work, they recommended I do the bladesmithing competition at TMS,” Sam said, referring to the annual meeting of The Minerals, Metals & Materials Society.

While managing meetings with 30-40 group members requires working out a lot of logistics, Sam has experience as the vice president of UConn Material Advantage Chapter. He also participated in environmental campaigns with UConn PIRG (UConn’s chapter of the Public Interest Research Group)and the Husky Ambassador Program.

“I’d be doing all this stuff on my own anyway, so I kind of like teaching people and it’s nice seeing others interested in this stuff. We’re all having fun. It’s a good group.”

Sam, a fifth-year senior, hopes the group can make it to the annual TMS bladesmithing competition, even if it means he won’t be around to see it.

Author: How MSE Prepared Michelle Such to Enter a Growing Industry

By Amanda Song 

Michelle Such

MSE undergraduate Michelle Such

MSE undergraduate Michelle Such is searching for ways to create aircraft parts more efficiently using 3D printing. Since 3D printing has grown to a multi-billion dollar industry, Michelle’s research is right on the money. But exploring new ways to use additive manufacturing for aerospace parts also enables engineers to create custom aircraft parts faster and more cost-effective than before. Ultimately, this allows for lighter aircraft with reduced carbon emissions, and helps speed repairs for older aircraft. Below, Michelle explains how MSE guided her toward this career path. 

What first attracted you to the UConn MSE program? 

The welcoming faculty attracted me to the MSE department. The professors and lab staff welcome students and encourage us to learn, do research, and find what interests us most in the MSE department. I chose to study Materials Science and Engineering because there are many different career opportunities and industries one can go into with this degree. One acquires a wide range of scientific skills that will help you grow as an engineer.  

How did research help you find a specific interest within MSE?   

Casting has really caught my interest in the Materials Science Department. Professor Harold Brody provided his expert advice on the subject during my independent study project and I gained a wealth of knowledge in his alloy casting course (MSE 4038).  

During 2018, I conducted research under the advisement of Dr. Harold Brody and Adam Wentworth. I researched additive manufacturing technology, capabilities, and limitations, focused on applications in the local aerospace industry with a case study and hands-on experience with FDM 3D printing. Additionally, I researched the investment casting process including: work piece preparation, investment mix processing, mold design, casting defects, microstructure, surface finish, and post processing techniques. 

How did your experience as an MSE undergrad student prepare you for industry?     

As an MSE undergraduate student, we complete a great deal of hands-on projects in the Materials Laboratory. These projects assist with student learning because we work in teams to solve complex engineering problems. For me personally, these projects and the MSE department as a whole have helped me to excel as an engineer, making my undergraduate experience challenging but exciting.  

Parts for airplanes have been investment cast for many years. However, some companies are now researching ways to additively manufacture parts to obtain them with feasible geometries.   

What are your career goals, and how has UConn MSE helped you achieve them?   

After graduating in May 2020, I will be going into industry to be exposed to Materials Science and Engineering in a different environment. Ideally, I would prefer to go into the aerospace industry since my independent study research is heavily used in this industry. I plan on getting a Master’s Degree part-time while working in industry full-time. The MSE department has helped me gain experience in multiple areas of Materials Science while being placed in challenging situations. 

How else have you been involved in the community? 

Earlier this year, I was inducted into the Materials Science and Engineering Honors Society, Alpha Sigma Mu. I am Vice President of Alpha Sigma Mu and I am a member of Materials Advantage (UCMA). For volunteer work, I am The Major Experience (TME) Mentor for MSE which involves actively answering undecided students’ questions about MSE and advise if the major will be a good fit for them. I have also volunteered for YESS (Young Engineering Science Scholars) and the Explore Engineering Programs, where I presented to high-schoolers about 3D printing and investment casting, instructed and supervised them in the Materials Laboratory, and gave presentations on material classes and applications. 

How was your overall experience as an MSE undergraduate? 

The UConn MSE department strongly promotes student learning. Professors are always eager to answer student’s questions and frequently hold office hours for students to go for extra help. The MSE faculty are truly motivated to help students learn and want to see everyone succeed.

Author: Grad Student Sharon Uwanyuze Wins a Rare Scholarship for Her Work on Refractory Ceramics

Sharon meets George Gower (President of Refractory Minerals Inc.), to discuss the raw materials on the banner which his company supplies.

Sharon meets George Gower (President of Refractory Minerals Inc.), to discuss the raw materials on the banner which his company supplies.

Sharon Uwanyuze, a Ph.D. candidate in Assistant Professor Stefan Schaffoener’s lab, was one of three students nationwide who received The Refractories Institute Award at the 2019 Fall Institute Meeting in Columbus, Ohio November 6-7.

The award includes a one-time grant of $5,000. They are given based on academic merit and the student’s interest and experience in the field of refractories, according to The Refractories Institute (TRI) announcement.

“My thesis is closely tied to TRI’s mission: advancing and supporting students who want to further their knowledge in refractory ceramics and then apply that in industry,” Sharon said. “They are called ‘refractories’ because they have great high temperature performance.”

Currently, Sharon’s research focuses on materials processing of refractory ceramics for titanium metallurgy, with an emphasis on corrosion and mechanical behavior at high temperatures. When she was looking at graduate programs, Sharon spoke to three professors at UConn’s MSE department. One of them was Stefan Schaffoener, who works with ceramics and composites focusing on corrosion, and high-temperature materials processing for aerospace applications.

“He works at the interface of ceramics and metals during titanium alloy casting,” Sharon said. “At high temperatures, molten titanium can oxidize rapidly.” This is a problem for Schaffoener’s lab group, because current ceramic casting molds do not sufficiently limit oxidation. Once titanium picks up more than 0.2 wt% oxygen, the toughness at the metal’s surface is drastically reduced and it will no longer be suitable for most aerospace applications. Therefore, this surface layer is currently milled away mechanically or chemically. However, if researchers could sufficiently understand and control the melting process and the refractory ceramic composition, this oxidation problem could be mitigated.   

“That challenge initiated the research I’m working on. I synthesize the materials of the ceramic casting molds that titanium is melted in and analyze their properties and performance,” Sharon said. For instance, if they use a ceramic mold that forms a barrier between titanium and the ceramic material itself, that prevents further diffusion of oxygen from the mold into titanium, and vice versa. While zirconium oxide-based molds work well with other metals, zirconium  tends to diffuse into highly reactive metals like titanium alloys and contaminate the metal.

“We’re now working on other ceramic materials such as calcium zirconate. Zirconia has a high melting temperature and excellent stability. By doping it with other elements we can make it even more stable with titanium,” Sharon said.

Earlier this year, Sharon completed a summer internship at Oak Ridge National Laboratory (ORNL), working on ceramic matrix composites for energy-producing (nuclear) applications. She used her knowledge of ceramic processing and properties to work alongside Dr. Stephen Raiman, a Research & Development Associate in Corrosion Science at ORNL.

But her path to the TRI scholarship wasn’t always this clear.

“It was exciting to win. I had tried to apply for that scholarship as an undergraduate while working in an Advanced Ceramics laboratory, but I didn’t get it. Now they can see I’m truly focused on refractory ceramics.”  

As an undergraduate at the University of Alabama at Birmingham, Sharon was a research assistant in an advanced ceramics lab, which was unique in their metal-focused program. She worked on synthesizing yttria-stabilized zirconia for ceramic applications.

“While working as an undergrad research assistant, I was encouraged by my advisor to pursue grad school because I was research-driven and had good grades. It was great advice, and I like to speak to undergrads and show them that grad school is a great possibility,” Sharon said.

She had the chance to speak directly to undergraduates when she participated on a panel at UConn’s chapter of the National Society of Black Engineers (NSBE) in October. 

“It’s important to me because I was shocked to learn that on average, less than 5 percent of Engineering bachelor’s degrees go to black students. Our undergraduate program is very diverse, but I think a lot of students may think graduate school is not an option, especially if they’re first-generation college students.”

Sharon is the first in her family to do a Ph.D., and feels that UConn is a great institution for her. “Here, we have a lot of library resources, top-notch equipment, and a whole building dedicated to characterization and microscopy,” she said, referring to the UConn Tech Park. “So we want to encourage undergraduates to look into that too.”

Sharon added that the professors in the MSE department are very approachable and willing to mentor students. “In Dr. Schaffoener’s group, we currently have three undergraduate research assistants, one of whom I help mentor. I was once in this position as an undergrad, and having research mentors is truly a phenomenal resource,” she said.

Sharon plans to use the grant money to invest in a high-power desktop computer for her lab, so she can improve her studying and experiments.

Author: Undergraduate MS&T Awards Include $1750 and Grad School Prep

The UConn undergraduate team at MS&T 2019


By Amanda Song

Materials Science and Engineering undergraduates won awards totaling $1750 for dome design and research presentations at the annual Materials Science & Technology conference in Portland, Oregon September 29 to October 4.

UConn Materials Advantage (UCMA) goes to MS&T each year to provide undergraduate members with the opportunity to explore MSE topics they might be interested in, and to see what kinds of research and research teams are out there.

UCMA undergraduates Amanda Agui, Samuel Bedard, Lucas Enright, and Justin Hewitt competed in the Geodesic Dome Design Competition against eight teams from universities across the U.S, with a 3D-printed ABS plastic dome.

“Winning best in destruction was not our objective, but I suppose it shows that we optimized our dome for the criteria of the competition,” Lucas said.

The domes were judged based on aesthetics, strength-to-cost and strength-to-weight ratios, a presentation and poster, and overall mechanical strength. While they weren’t aiming for it, the UCMA team’s dome shattered in an impressive explosion that earned them the Best in Destruction award for $500, while the weight-cost-strength ratio of the dome earned them Runner up for $750.

“We realized the advantages of 3D printing and the design created by the 2018 team, which included Zachary Putney, Iwona Wrobel, Jordan Gomes, and Justin Hewitt (also on this year’s team). We modified their design and optimized the processing parameters of the dome after printing,” Lucas said.

Modifying the prior years’ design turned out to be a major advantage. “Many teams casted their domes from molds or had other one-and-done sort of solutions and if they discovered a weakness in their design, it would be expensive and time consuming to correct. We, on the other hand, could tweak our CAD file over and over,” Lucas said.

MSE senior Victoria Reichelderfer won the Undergraduate Student Speaking Contest at MS&T, with a presentation titled “Phase Field Modelling of Corrosion.”

Additionally, Victoria Reichelderfer, a seventh semester MSE undergraduate, won first place in the annual Material Advantage Undergraduate Student Speaking contest. The contest is designed to encourage undergraduate students to present technical papers and to improve their presentation skills.

The award, which includes $500 for first place, recognizes Victoria’s presentation on “Phase Field Modeling of Corrosion.” In addition to the award, Victoria gained an invaluable experience that will prepare her for her future in graduate school and beyond: she got to present her research in a professional setting for the first time.

“I’m applying to graduate schools now, and I wanted to expose myself to the experience of presenting at a conference,” Victoria said. “It was a good experience because I’m going to have to do that in the future.” It was her first time attending a conference as an undergraduate.

Her presentation was the culmination of a project she started last spring, while taking her advisor Professor Serge Nakhmanson’s graduate level course on phrase transformations of materials. Traditionally, it is challenging and computationally expensive to model phase transformation and corrosion. Victoria’s research aims to address this by using computational models to track phase transformation, which helps researchers deepen their understanding of the process.

“Professor Nakhmanson gave me some general advice about presenting. Another grad student, Lukasz Kuna, is a great presenter and he gave me a lot of tips about the look of the presentation, and presenting in a professional setting,” Victoria said. Moe developed a video simulation of dendrite corrosion that Victoria used in her presentation, which she believes helped her stand out from the others.  

“I have an interdisciplinary goal. I like biomaterials, but I’m also really interested in the cell biology side and what happens when cells and tissues interact with materials,” Victoria said.  While her list of six potential graduate school programs is not yet solidified, Victoria plans to use some of the $500 award to fund her applications.

“Our work in MSE was practically everything that lead to this win,” Lucas said. “Our collective backgrounds in materials science gave us knowledge of materials processing and the engineering process as it applies to materials. We knew the properties of the dome we were trying to maximize, and our MSE background made 3D printing a brittle polymer an intuitive choice.”

After spending four consecutive days with her peers at the conference, Victoria feels grateful that the MSE program’s small class size helped her bond with her classmates.

“I’m excited for what comes after graduation, but I’m going to miss UConn. I chose MSE as a major because the program was small. I know everyone in my classes and there’s always someone I can study for an exam with or ask for advice. I hope to find this kind of community again,” she said.

Victoria used a video in her presentation that demonstrates the modelling of phase transformation and corrosion. Her labmate, Moe Daeipour, created the video.

Author: From Failure Analysis to Blade Design

By Amanda Song

MSE alumna Rheanna Ward

After spending years analyzing the reasons why helicopter parts broke, Materials Science and Engineering (MSE) alumna Rheanna Ward has learned that failure is rarely the end. In fact, many successful designs and products have resulted from failure. After being involved for several years with analyzing why parts break, Rheanna wanted to transition to the front of the problem by designing blades which can operate under harsh conditions and help rescue people.

“My personal goals are intertwined with work so it would be difficult for me to separate the two. I put a lot of effort into my work and I want to make an impact on the engineering community,” Rheanna said.

Since graduating UConn with her BSE in 2015, Rheanna has worked at Sikorsky, a subsidiary of Lockheed Martin, first in Materials & Processing (M&P) conducting failure analysis on aircraft parts (identifying how and why part of an aircraft broke during test, flight, or development), and now in Blade Development designing blades for commercial and military use. Throughout her four years working at the company, she has continued to build on lessons learned in MSE, forge relationships with her coworkers, and learn “more than she could have imagined.”

“I enjoyed working on composite failures the most because they were different and not as well documented or understood as metal failures,” Rheanna said. “We looked at parts under the light microscope, in the SEM, and pieced everything together to come up with a story on how parts failed.”

 “There are people who understand the processing, performance, and structure for composites in depth, but the knowledge is not as widespread as it is about metals,” Rheanna said.

During her time in M&P, Rheanna often worked with the Blades Engineering Department, and got to know the manager and team there well. When a position opened up in Blades Development, the manager approached Rheanna and asked her to join their department.

“I had never designed anything before, yet he insisted I would learn how and thought I would like the group. I’ve been in this position for about a year,” Rheanna said, adding that she’s happy she stepped out of her comfort zone to delve into blade designing.

In Blades Development, Rheanna and her team take broad requirements about new developmental aircraft and design blades for the appropriate lift and operating conditions. “We rely on other groups to give us input such as how much the blade must lift, if the aircraft will be in a harsh environment (excess sand or saltwater), and if there are certain materials to use,” she said. “It’s pretty neat to see all the new technologies emerge and see the final product you worked on in the end.”

Rheanna credits the group work her MSE instructors assigned as some of the best preparation for industry work. By working together to dissect challenging problems and work out the solution, Rheanna got her first taste of what it would be like after graduating.

“No one designs anything alone, and learning to talk to people and respectfully disagree and present facts on why things should be done a certain way is important.” This collaborative effort has enabled her to come up with new ideas for designs or materials. “These new discoveries are allowing us to push the limits of materials and design better, longer lasting parts. I look forward to when we can design parts that have an infinite life.”

Rheanna’s cohort while in MSE comprised about 30 people per class—today, it’s grown to 40 students per class. This small group of students all knew each other well and worked on homework together. “I was able to have class with my best friends every day which was really special. Some of my best memories were sitting in E2, studying with our group, and ordering wings and watching YouTube videos to take a break from our work,” Rheanna said.

“My advisor, Professor Alpay, was always there to support me and give me direction whenever I was questioning myself. I owe a lot of my success to him because of all the positivity he offered me when things got tough.” Such advice is particularly useful to Rheanna today, as she is pursuing a master’s degree part-time, while also working full-time. Rheanna thinks of it as “short-term pain for long-term gain.”

After earning her MS and becoming a better designer with CATIA, the design software suite she uses for computer-aided engineering at Sikorsky, Rheanna wants to manage a development program and become an Integrated Product Team lead for the entire helicopter rotor system, which extends beyond blades.

“When I think of where I started four years ago, I believe in five years I will be ready for a whole new set of challenges. We are lucky that Lockheed Martin (who owns Sikorsky) has so many different divisions. I can see myself rotating to Lockheed Space or Missile and Fire Controls at some point,” she said.

Since graduating UConn, Rheanna has remained involved in the UConn community. She helped develop senior design projects on behalf of Sikorsky, gave tours to Bridge students—a five-week intensive summer program to prepare students underrepresented in engineering fields for their studies in UConn Engineering—and helps recruit at UConn whenever Sikorsky attends a career fair. She looks forward to Material Advantage Banquets as an alum as well, an event close to her heart because she helped initiate the annual banquet when she was Vice President for Material Advantage in 2014.

When asked what advice she would give future undergraduates, she said, “I try so hard to do everything perfect the first time that sometimes it’s difficult to accept I may fail. Ask your peers and teachers for help when you can’t figure something out. Not everyone expects an answer immediately. If I don’t know the answer to something, I know enough to say, ‘I don’t know, but I can find out.’ And my MSE degree gave me the foundation to then go and solve the problem.”

Author: MSE Alumnus and Small Business Entrepreneur Brings a Unique Perspective to the External Advisory Board

Neal Magdefrau in Electron Microscopy Innovative Technologies’ new office in Tolland, CT


By Amanda Song

As one of the first graduates of the newly-formed MSE program in 2005, and a subsequent MS and Ph.D. graduate of the program in 2013, Neal Magdefrau has watched UConn’s MSE department grow from five students and a few faculty, to 41 faculty and over 250 students.

In the coming year, he will return as the newest member of the External Advisory Board, joining ten other industry partners in working to strengthen the visibility of the UConn MSE Department at the university, state, and national level, and to assist with strategic planning.

During his 12 years at UConn, Neal served as President of the UConn Material Advantage (UCMA), and as a member of ASM and TMS. He completed his Ph.D. thesis titled “Evaluation of Solid Oxide Fuel Cell Interconnect Coatings: Reaction Layer Microstructure, Chemistry and Formation Mechanisms” under the advisory of Professor Mark Aindow. 

The three-time MSE graduate is now a small business entrepreneur and staff engineer and research scientist in the Measurement Science Group at UTRC. He works part-time at UTRC while cultivating his company Electron Microscopy Innovative Technologies, which is the first and only business in the U.S. offering rentals of desktop Scanning Electron Microscopes (SEMs).

“I believe the technology industry in Connecticut is at the beginning of a resurgence, and small technology startups are going to have a major impact in repairing the state’s stagnant economy,’ Neal said. His business has grown “about 30 percent year-over-year,” he said, adding two new SEMs to their rental fleet and recently opening a second office location in Tolland, CT.

Neal has spent most of his time at UTRC working on high temperature materials and coatings for ceramic matrix composites, as well as running programs at UTRC in the areas of bulk metallic glasses (BMGs) and atomic layer deposition (ALD). But what excites him most is working with cutting-edge equipment to solve problems.

“The best days are those where I can help a customer solve an issue that they haven’t been able to resolve without using advanced materials characterization.  The reason I started my business is to put more powerful microscopes in the hands of more companies to help them address their R&D and manufacturing needs.”

In 2012, Neal received the Senior Vice President’s Award, given by the CTO to their small service group for outstanding service. He holds eight patents and has more invention disclosures pending.

In September, Neal was invited to join the External Advisory Board after alumna Alexandra Merkouriou stepped down to continue her research at UConn’s Airforce Research Laboratory—Research in Advanced Manufacturing, and to pursue a Ph.D.

Sergey Galitskiy examines the fracture of nanocrystalline material due to laser irradiation in Associate Professor Dongare’s lab.

Sergey Galitskiy examines the fracture of nanocrystalline material due to laser irradiation in Associate Professor Dongare’s lab.


By Amanda Song  

Exploring ways to strengthen lightweight structural materials in order to withstand deformation and survive under extreme environments is understandably complex. But this scientific process motivates Sergey Galitskiy, Ph.D. student in Associate Professor Avinash Dongare’s lab, to continue his research on modeling the material response of metallic systems under conditions of impact/shock loading. When he does produce results, the chance to share that with the Materials Science and Engineering community is thrilling.  

Sergey’s research focuses on investigating the mechanisms of fracture for Al and Mg based materials under shock loading conditions that result in very high strain rates (~107 – 1010 s-1). His primary focus is examining how these Al and Mg structures react on the atomic scale to plate impact or laser induced shock, which has not previously been theoretically investigated. The work uses classical molecular dynamics (MD) simulations to investigate the evolution of defects (dislocations) and phase transformations (melting) during failure.  

“What we’re doing is modeling the irradiation of a thin film by an ultra-fast laser, generation of a resulting shock wave, and usually the consequential fracture of the material,” Sergey said. “There are pros and cons of investigating a material’s strength with laser-induced shock. On the one hand, very high temperature leads to material ejection. On the other hand, in comparison to high-velocity flyer (explosive) approaches, lasers provide precise control of the energy deposition which can more readily be compared to our theoretical work.”  

Sergey’s research titled “Dynamic Evolution of Microstructure During Laser Shock Loading and Spall Failure of Single Crystal Al at the Atomic Scales” featured on the cover of the Journal of Applied Physics.

Sergey’s research titled “Dynamic Evolution of Microstructure During Laser Shock Loading and Spall Failure of Single Crystal Al at the Atomic Scales” featured on the cover of the Journal of Applied Physics.

The understanding of material behavior (fracture) in such extreme conditions can be useful for the defense and aerospace technologies. For instance, if they can create an aluminum-based structure that is both lighter and stronger than what is already used to build airplanes, they could potentially reduce fuel costs and enhance maneuverability.   

Sergey’s first article, highlighted on the cover of the Journal of Applied Physics, demonstrates the ability to model the spall failure under laser shock loading. He and Dr. Dongare were able to investigate how laser loading conditions and crystal orientation result in variations in dislocation density evolution and failure behavior.  

“One challenge in the applicability of the MD method is that one can usually only model systems with sizes of a few hundred nanometers,” Sergey said. But his advisor developed a technique that scales the MD simulations to model large systems, up to tens of microns. This method, Quasi Coarse Grain Dynamics (QCGD), is able to retain the atomic scale characteristics of the defect evolution, phase transformation behavior, and failure behavior, all for a fraction of the cost of running MD simulations. 

We have extended the capability of the QCGD simulations to model laser interactions with metals, allowing the modeling of systems and phenomena that are relevant for laser shock loading and additive manufacturing. 

Building on some of his predecessor’s work is part of what makes the scientific process exciting for Sergey. The opportunity to meet and work with pioneers in the MSE field, including the chance to work with his advisor, Dr. Dongare, was a major factor in his decision to join UConn’s MSE program as a Ph.D. student.  

Before coming to UConn in 2016, Sergey earned a Bachelor’s and Master’s degree in Physics from South Federal University in Russia, and was working as a Research Assistant at the University of Kassel in Germany, experimenting with organic atomic systems.  

During my last project in Kassel, I worked in modelling the processes in neuron cells on the atomistic level There, I gained experience in MD simulations, and I wanted to continue my scientific work with this method,” Sergey said. 

When Sergey discovered that Dr. Dongare’s group is also doing MD simulations—with metallic, rather than organic, systems—he knew he had to join them. When he eventually joined the lab, he got to build on his experience working with a Two-Temperature Model (TTM), which describes laser radiation interaction with matter on an atto – femto second scale of (10 ^-18 – 10 ^-15 seconds), and extend the model to some metallic systems. 

But transitioning from Physics to MSE, and from consuming others’ research to meeting the researchers and producing his own theories, isn’t easy. Sergey credits UConn’s MSE program for helping him develop as a scientist, providing him with the training and MSE courses to become successful in his research, and providing professional development opportunities.  

 When I started my scientific career in Russia and Germany, I never spoke to the scientists who came before me. I just read their books,” he said. “But here, at TMS conferences, for instance, scientific book authors came up to my peers and were introducing themselves. Those people who created the field, who are on the tip of the science, you get to meet them,” he said. 

 “To me, appreciation is one of the best gifts in scientific society.”   

Author: MSE Grad Student Commended in 3-Minute Thesis Competition

By Amanda Song

Byung Jun

Byung Jun, Ph.D. student, Materials Science and Engineering

Byung Jun, Materials Science and Engineering Ph.D. student, received honorable mention in this year’s 3MT® Three Minute Thesis Competition, for presenting his research to a general audience.

“My presentation discussed the effect that sand in the air can have on jet engines and their durability,” Byung said. “My work is on analyzing this interaction between contaminants in the air and specifically, the high temperature resistant coatings that the jet engines have.”

Each year, the UConn Graduate School hosts the school-wide competition, encouraging doctoral students to present their research in an impactful and condensed three-minute version. The winning presentation is then submitted to the global competition to compete against universities from around the world.

Condensing years of research and, often, many complex scientific terms into a three-minute speech for a non-technical audience is a challenge. But it’s an invaluable experience and a beneficial skill for many STEM researchers.

“The biggest benefit is in improving one’s ability to communicate with the rest of the world. It’s no use if you can’t tell people what amazing work you’re doing, right?” Byung said. “It’s hard to take that step back if you’re always surrounded by the same professionals who share that same language with you.”

Byung hopes to work in a teaching position in the future, where “any public speaking practice is good practice.”

“The notion of parsing through the content to adjust to your audience is an important lesson that I believe is applicable anywhere,” Byung said. 

This year’s winner was Pharmaceutical Sciences doctoral student Koyel Sen with her presentation on custom-built drug dosages using 3D printing techniques.

By Marlese Lessing

Sean Ketchum, a 2008 UConn MSE alumnus and director of metallurgy at Ulbrich Stainless Steels & Special Metals, was one of the first UConn MSE graduates to work at the world-renowned Wallingford steel company, and he certainly won’t be the last.

Sean, along with Samantha Brantley (B.S. 2015), Samuel Guerra (B.S. 2017), Allie Kelley (B.S. 2015), and Keith Grayeb (B.S. 2009), are all alumni of the Department of Materials Science and Engineering, and are all working full-time at the company with their degrees in materials science.

Keith, currently senior process metallurgist at Ulbrich, was the first intern at the company, working there over the summer between his sophomore and junior year in 2007. When he graduated, he worked at Sikorsky for a year before Ulbrich reached out to him with an offer, where he has been working for eight years since.

Sean, on the other hand, started his position as he graduated, based on a recommendation from a professor.

“I really liked the flexibility of Ulbrich, in terms of being able to chart my own course,” he said.

The other graduates began to trickle in, as the company began to have a greater presence in UConn’s career fairs, and began supporting Senior Design projects for MSE. 

Allie Kelley, an associate process metallurgist at the company, was hired at Ulbrich after the company funded her Senior Design project.

“When they interviewed me for the job, I realized I loved the group I was going to be working with,” Allie said.

Since Keith’s internship and Sean’s hiring, the two have made an effort to include UConn in hiring new graduates, and in including Ulbrich in UConn’s growth as a premier STEM-based university and research hub for Connecticut.

“It feels that the UConn presence has grown with the materials science program size,” Sean said. “From there, we’ve followed the progression of the program. We’ve funded more Senior Design Projects, we’ve hired more interns from MSE, we’ve recognized our need to have young, technically-educated people in our company. MSE has grown to meet that need.”

“We’ve developed this manufacturing-academic relationship with UConn MSE,” Sean said. “We know the professors, we get to know the students through their Senior Design projects and internships, it’s been an interesting progression.”

It’s not just projects and hires that Ulbrich is looking at now, Keith said. Soon, the company will start to use UConn MSE’s new resources at the Innovation Partner Building.

“We’re expanding beyond just a pipeline of internships,” Keith said. “UConn has a lot of resources in analytical equipment, like AFMs, to test new products. Now with the Innovation Partnership Building, we’re hoping to form a further partnership with UConn for using, and training with, the analytical equipment MSE has to offer. This equipment will help Ulbrich be able to better adapt to the market.”

“In order to best serve our customers, we need to look at things the same way our customers do- and they often have the analytical equipment that UConn does,” Keith said.

As the University continues to adapt and expand towards Connecticut’s industry needs, companies like Ulbrich are given more opportunity to partner with the university for R&D, creating a two-way road between businesses and the academic world, Sean said.

“UConn MSE’s expansion into market and company services is beneficial to Connecticut-based manufactures like Ulbrich,” Sean said, “that may not have the room or resources for the analytical equipment they need. UConn funding so much equipment and expertise at the IPB is a great fit, which means we can begin to create that knowledge here.”

As Ulbrich continues to look to expand its relationship, the company plans to keep on hiring interns and MSE grads—both in due to the quality of MSE’s education.

“We all had different backgrounds and internships, but we’re all in the same kind of mindset,” Sean said. “When we come into manufacturing, we’re able to bounce different ideas off of each other. We have a desire for connectivity. We all just want to exchange information.”

Even though many of the alumni have different ideas and experiences, many of them have gone through the same courses that Sean and Keith went through 10 years ago. “Those classes are a way of proving that an applicant has an acceptable work ethic,” Keith said. “Hard classes that we all took have a way of breeding critical thinking, which help foster the mindset that we’re looking for.”

Sean added that many of the concepts and contexts that his fellow MSE graduates are taught are easily relatable, even though many of the graduates are in different departments of the company.

“Being able to reference a common experience or example that a professor taught us, really helps with understanding,” he said.

For many of the alumni, their professors and advisors were a keystone in their development as engineers and dedicated students.

“Professor Harold Brody is the fundamental reason I began at Ulbrich,” Sean said. “Professor Brody knew directly of an opening at Ulbrich that fit what I was looking for. By Friday morning of that same week I had an interview, and by Friday afternoon I had an offer. Our small graduating class reflected as we parted MSE on how our advisors had all worked to support our professional or academic transitions.”

For Samantha, the support her advisor, Professor Pamir Alpay, gave her during her time at UConn helped her through her journey as an MSE student, and have her contacts for her career in Ulbrich.

“Professor Alpay always encouraged me when the MSE curriculum tested my stamina,” Samantha said. “If I had a month of rigorous workload ahead, he would frequently check-in and even schedule weekly meetings for support. Pamir has a well-established network and would often recommend that I get in contact with his colleagues currently in industry. The professionals I met through his guidance made the differences between academia and industry clear, providing me with the confidence a minority in STEM needs. By creating an open and honest mentorship, Professor Alpay truly influenced my career path for the better.”

Overall, Sean said that he is grateful for the experiences that MSE was able to provide for him and his team of MSE graduates. Sam Guerra, associate process metallurgist, said that without the University, he wouldn’t be as successful as he is today.

“The MSE program was able to give us so much stuff we wouldn’t be able to access normally,” Sam said. “It’s really great to see my company hiring people from the same program, and to see that they’ve been able to keep up with the industry.”

Sean agreed.

“The MSE department is really positioned to care about what happens to alumni after they graduate,” he said. “They get students ready to enter, and succeed in, the workforce.

Author: Undergraduate Victoria Reichelderfer Develops Skills as Legacy Leadership Student

Marlese Lessing

MSE junior Victoria Reichelderfer

MSE junior Victoria Reichelderfer

MSE junior Victoria Reichelderfer is paving new paths for interdisciplinary leadership through a ‘Legacy Leadership’ experience, connecting her love of biology, teaching, and materials science and engineering through the opportunities provided by this prestigious program.

UConn’s Legacy Leadership Program aims to help students deepen their abilities as leaders, develop their connections with both peers and alumni in their given career paths, and prepare to make a better future for themselves and others as selfless, practical, responsible, and forward-thinking individuals. The program requires nomination by a faculty member and an extensive interview process to be accepted—in this case, she was nominated by MSE department head Professor Bryan Huey.

It’s a well-deserved position for Victoria. With a passion for biomaterials, she’s devoted her time to doing research in Professor Serge Nakhmanson’s lab since her sophomore year working on simulations for nanomaterials.

Professor Nakhmanson calls Victoria an “exceptional, very hard-working student.”

“I was involved in the Legacy Leadership Program nomination process for Victoria and I am very happy to hear that she finds this program enjoyable and useful for the development of her career,” he said. “Considering how closely we work now on multiple research topics, plus with Victoria currently taking my graduate-level class on phase transformations in materials, it is amazing how she finds extra time to participate in all of these outreach and leadership activities – and that is without drinking any coffee…”

On top of her research, Victoria also teaches prisoners physics at a correctional institute since her freshman year through the ‘Second Chance Educational Alliance.’

The prison education program helps reduce recidivism, Victoria says, and gives the prisoners a goal to work towards. Aided by two teaching assistants, Victoria visits her students once a week.

“That’s probably my favorite thing I’ve done in college,” Victoria says. “I make all the homeworks, and I get notes from my previous teachers and professors. It’s a little different than a traditional school environment, but we make it work. The prisoners love it. They are amazingly smart and motivated, which motivates me, and it’s why I like it so much.”

As a member of the Legacy Leadership Program, Victoria further develops those skills through meetings and activities. Once every two weeks, she meets with other members of the program to discuss the obstacles they’re facing.

“We talk about things that challenge us. We try and push ourselves out of our comfort zone,” Victoria said. “It does a good job of encouraging personal development, and showing you how you have opportunities to grow every day. We also learn to understand others and appreciate and develop empathy as a leader.”

Earlier in February, Victoria and her fellow leaders visited the Connecticut Forum in Hartford.

“We got to see Julia Gillard, the former Prime Minister of Australia, and Samantha Power, the youngest-ever American ambassador to the United Nations. She gave a talk on America in the world, how we as a country are a leader in the world, and the kind of responsibility which comes with that. It was cool to get her inside perspective and see how it really works,” she said.

All Legacy Leaders are paired with a faculty advisor and an alumni advisor to help with academic and career guidance. Because of her interest in working with biomedicals, Victoria chose molecular and cell biology assistant professor Thomas Abbott, whom she had taken several classes with before.

“It’s nice to have somebody who has a different perspective to add to my engineering rigor,” Victoria said. “We just get along very well. We talk about leadership, the challenges of it, how to be a good leader.”

Dr. Abbott said working with Victoria has gone so well because they share a similar value system in terms of leadership.

“Victoria is quite passionate about her interests, and it shows. On top of everything else she does, this spring she is a peer mentor instructor for my Biology 1107 course. As expected, her session has been going very well,” he said. “What impressed me when she was a student in my class continues, and I look forward to our future Legacy interactions.”

Victoria said she went into materials science to combine both her love of biology and human medicine with her passion of engineering and analytics. When she graduates, she plans to study and develop biomaterials that act as drug delivery systems to the body.

“I love materials science because I can’t make up my mind. I was almost a pre-med, but with materials science, I can incorporate that by working with biomaterials,” she said. “My favorite one is the PLGA polymer, poly(lactic-co-glycolic acid), which degrades into chemicals that your body can handle. They make it in wafers and fill it with a drug for glioblastoma, a type of brain cancer. They open your head, cut out the tumor, leave the wafer, and it delivers the drug. It increases your life expectancy by 20 percent that way.”

Victoria said she wants to go into biomaterials engineering to continue doing what she’s doing as a leader and as a teacher: helping others.

“I want to know that every day when I’m going to work, I’m helping someone,” she said. “It’s helping people, and engineering systems, and biomaterials. It’s everything I want.”

Author: MSE Department Celebrates Accomplishments, Looks to Future at 2019 Banquet


By Marlese Lessing

The Department of Materials Science and Engineering enjoyed an evening of food, science jokes, celebration, reflection, and mingling at the sixth annual MSE Banquet in April. Held at the UConn Alumni Center, attendees included undergraduates, graduates, professors, administrators and alumni from Lockheed Martin, M Cubed Technologies, and more.

Organized by UConn Materials Advantage (UCMA) president Kenna Ritter for three years running, and presented by UCMA Social Chair Amanda Agui, this year’s banquet was a smashing success, combining a professional atmosphere with fun activities and light-hearted chatter from attendees and speakers alike.

“The goal this year was to involve more engagement and mingling,” said Amanda, who incorporated several science puns into her opening speech. “I want to make this night positive and light-hearted.”

To do this, the tables, which were named after periodic elements such as cesium, cobalt, and nickel, were seated with a mix of graduate students, professors, alumni, and undergraduates.

“We try and make it a nice event,” Kenna said. “We want to make it conversational and inviting.”

Before the dinner line was opened, the order of each table was determined in a team “Race-to-Taste” competition, which involved each table working as a team to answer questions about engineering, physics, and science. The winners were invited to line up first for their food.

While the activities offered a sense of fun, the banquet was also a time for celebrating and reflecting on the accomplishments of the MSE department over the past year.

Department Head Professor Bryan Huey highlighted the recent accomplishments of MSE’s faculty, such as Dr. Lesley Frame’s Heat Treat Award, Dr. Avinash Dongare being named UTC Professor in Engineering Innovation, and Dr. Seok-Woo Lee’s award for teaching excellence. Professor Huey also commented on the bright future of the MSE department, especially with UConn’s new Science1 complex providing future opportunities as MSE and the IMS continue to expand.

The event was also attended by special guest Dr. Diana Lados, a distinguished professor in mechanical engineering at Worchester Polytechnic Institute and Vice President for the Alpha Sigma Mu International Professional Honor Society. Diana helped Professor Hal Brody celebrate the induction of over a dozen new graduate and undergraduate members into this prestigious group.

Undergraduate students and graduate students were also honored and recognized for their hard work and accomplishments. Associate Department Head Dr. George Rossetti presented awards acknowledging outstanding contributions by graduate students in research, teaching and leadership activities.

“As an instructor for several of the core MSE graduate courses, I have the opportunity to interact with most graduate students as they first enter our program,” Rossetti said. “When evaluating and selecting candidates for awards, I am consistently impressed by the scope and strength of their research accomplishments and professional achievements during the course of their graduate studies.”

Associate Dean for Undergraduate Education & Diversity Dr. Daniel Burkey, who also attended, said seeing the accomplishments of the MSE department has been exciting.

“It’s gratifying to celebrate what students are doing,” Burkey said. “It’s been great to work with the MSE department. It’s not a department many people know about, but UCMA is wonderful about informing our freshmen about it.”

The evening ended with a classic materials science and UCMA demonstration: freezing marshmallows in liquid nitrogen for a special frozen treat as attendees left the Alumni Center.

Alumna Alexandra Merkouriou, who is a member of MSE’s advisory board, founded the banquet in 2014. She noted how it is gratifying to see the event grow and expand over the past several years.

“I’m really proud of where it’s come,” Alexandra said. “I hope it continues years into the future.”

MSE undergraduate student Hetal Patel has been awarded not one, but two fellowships – the National Science Foundation Graduate Research Fellowship Program (NSF GRFP) and the National Defense Science and Engineering Graduate Fellowship (NDSEG), the first undergraduate to do so in the history of the fellowship at UConn.

Hetal is a senior in the UConn Honors Program, a STEM scholar, a 2018 University Scholar, and the recipient of numerous awards and scholarships while at UConn. She has been conducting research in Dr. Seok-Woo Lee’s lab since her freshmen year and in Dr. Avinash Dongare’s lab since 2018. She is also the President of the Materials Engineering Honor Society, Alpha Sigma Mu, and the Vice President of UConn Materials Advantage. As an undergraduate, she has accumulated an impressive research and community outreach profile which has led her to win the two nationally prestigious graduate fellowships.  Hetal said she was “shocked” when she found out she had won NDSEG.

“I found out from the UConn Office of National Scholarships and Fellowships that I might be the first undergraduate that has ever managed to secure the NDSEG fellowship in the history of UConn and that I am definitely the first NDSEG fellow we have had in the last five years!” Hetal said. “I am also very happy and grateful to have received the NSF fellowship as it is a nationally recognized program for graduate students. I try very hard to submit my best work and had been working on the applications several months beforehand, so it feels good for all the hard work to pay off.”

Hetal thanks Dr. Seok-Woo Lee, Dr. Avinash Dongare, and Dr. Bryan Huey for writing her letter of recommendations. “My application would have been incomplete without the extremely strong letters of recommendation and I am very grateful to all the professors in the MSE department who have helped me get this far in my materials career.”

The NSF GRFP, which is the country’s oldest STEM graduate fellowship, recognizes graduate students with outstanding work in the STEM field to do Ph.D. work. The NDSEG is funded by the US Department of Defense to students pursuing a Ph.D. in a field that advances US defense science and engineering. Those who earn it display a high aptitude to advanced study and scholastic enterprise. It is sponsored by the Air Force Office of Scientific Research, The Army Research Office, and the Office of Naval Research, all of which falls under the Director of Defense Research and Engineering.

Like nearly all Ph.D. students in MSE, at UConn and elsewhere, tuition, fees, and a monthly stipend are provided. Recipients of these special fellowships earn a slightly higher stipend, and with the NDSEG there is also a generous travel allowance. Both of these awards are very hard to earn, with less than a 15% success rate for the NSF, and a 10% success rate for the NDSEG. Since she can only accept one fellowship, Hetal says she will accept the NDSEG because of its selectiveness and benefits.

“I have chosen to accept NDSEG as it is more selective, extremely prestigious, and has better financial package,” Hetal says. “NDSEG will fully fund my research as I head to UC Berkeley this fall to pursue a Ph.D. in materials science and engineering in the field of computational materials science. I will be utilizing atomic-scale quantum mechanical modeling methods and high-performance computing technology to accelerate the design and discovery process of materials for battery and other energy storage technologies.”

Her advisor, Professor Lee, says Hetal is “certainly one of the most brilliant, creative and productive undergraduate students I ever met at UConn.”

“She deserves all of the fellowships that she has received,” he says. “I have no doubt about her future success. I wish her all the best in her endeavors as a materials scientist.”

This year at UConn 11 students have won the NSF GRFP are highlighted in the UConn Today article

Author: MSE Seniors Reach for the Stars with NASA Senior Design Project

MSE seniors Zachary Putney, Jonathan Gager, Ryan Wrobel and Spencer Matonis are currently elbows-deep in the opportunity of a lifetime: Helping building the next generation of 3D printing in space.

The four are working on developing a recyclable polymer composite for 3D printing objects for NASA astronauts. In March they visited their Senior Design sponsor at the George C. Marshall Space Flight Center in Huntsville, Alabama, where they met some of the aeronautics engineers and researchers, toured the facility, and dropped off some of their samples for further testing.

“We’re really thankful and happy to be able to be working on this,” Spencer said.

The group’s efforts are a part of their Senior Design Project, a two-semester course that partners senior MSE students with industry sponsors to use their materials science knowledge, creativity and problem-solving skills to tackle real-world engineering issues and tasks. Throughout, they’re mentored by MSE professors, industry professionals and experts from their sponsor company.

NASA has been collaborating with the MSE department for eight years now, focusing on 3D printing. which has become ubiquitous in the world around us and even beyond—it is now also an essential part of living and operating in an enclosed microgravity environment such as the International Space Station.

“This is an opportunity for the students to work both with each other and with a groundbreaking agency,” the group’s advisor Dr. Volkan Ortalan said.

“Our student team has taken on a big challenge—development of novel feedstocks for in-space manufacturing utilizing 3D printing,” Dr. Ortalan said. “I have observed our students bringing their ideas and engineering designs to life. I have seen them working on several technical presentations and reports, working on novel filament development for 3D printing, collaborating as a team, and working diligently to meet the numerous NASA deadlines.”

The students’ Senior Design project is ultimately focusing on creating a printing material that’s both light and durable– perfect for crafting tools needed to operate a space station, without sacrificing strength for weight economics. This is critical when sending materials to the ISS, or to possible future human colonies on the Moon or Mars.

“We’re looking at how we can create stronger plastics that can match the properties of metals,” Zach said. “We also need to be able to replicate the properties of some specialty items.”

The properties include dielectrics, which effectively store a charge and can be incorporated into batteries. One of the team’s current challenges is efficiently integrating dopants into the matrix material so it still retains the properties and the printability of plastic, while supporting that electric charge. Currently, the group is using Ultem, a highly-durable 3D printing material, as a base.

“A lot of this project has been figuring out how to get the dopants into the Ultem,” Spencer said.

The group’s current methodology is to use strong solvents to dissolve small pellets of the Ultem into a gel, mix them with a powder form of the dopants, and cast this into wafer molds. These can then be fed into a high-temperature extruder and wound onto a spool for transport before it’s loaded into a fiber-fed 3D printer.

As part of the Design Project, the group has already sent several of the wafers to a professor at Auburn University, who will be working to characterize the material and see if the dopants are working as expected.

“So far, NASA has been super happy with our results,” Spencer said. “We’ve encountered our share of problems, but we work through them and have been able to stay on track.”

For all four students, the opportunity to work with NASA is an exciting prospect, especially as they’re establishing connections and helping solve issues as part of their Senior Design. Ryan said he wants to work at NASA as an engineer after he graduates, and sees this as a way to get his foot in the door.

“Ever since I was young, I’ve been fascinated by space,” Ryan said. “Even if we’re not directly contributing to what NASA is doing, we’re still a part of it.”

Spencer is grateful that he’s able to contribute to the “Second Space Race.”

“I’m a little remiss to miss the first space race, but now I get to work on the second one,” Spencer said. “You might not get that opportunity ever again.”

For Jon, the ability to gain hard experience on the project is one of the most valuable things for him.

“This is the first open-ended project I’ve ever had,” he said. “I get to find and develop solutions and work with others. You can’t learn that from a classroom. It’s very rewarding.”

While the team is wrapping up their project for Senior Design Day at the end of the semester, they are eagerly awaiting the characterization results from their collaborators.

Ryan said working with NASA’s engineers has been great, as the agency is open with their communication and enthusiastic to work with students.

“I remember we went to Huntsville to take our samples over, and we met with the engineers,” he said. “When we gave them the samples, one of the engineers replied ‘It feels like Christmas….’”

While it is a student-based project, the team is expected to meet the expectations of the agency they’re working with, Dr. Ortalan said.

“This project was treated like a regular NASA approved project and necessitated maintaining a budget, meeting numerous requirements, and communicating with NASA officials,” he said. “This work can have an important impact on current and future NASA research and programs. It is truly fulfilling to see what students can achieve when presented with an opportunity and given the support to explore their curiosities.”

By Marlese Lessing

Kyle Crosby earned his undergraduate degree, master’s degree, and his Ph.D. in materials science at UConn after spending nearly a decade working and researching in the department. He now works for ZEISS Microscopy, the German company behind MultiSEM, the world’s fastest scanning electron microscope which is used to scan everything from mouse brains to microchips to shale rocks. A Pennsylvania native, Dr. Crosby came to UConn MSE both to experience something new, and to receive a top-notch engineering education.

To start, tell us about your work.
Imaging and spectroscopy, specifically electron microscopy, are subjects I’ve been interested in since I worked with these tools at UConn. I’m currently in a business development role supporting sales and service colleagues from an applications and product marketing perspective. While I’m not directly operating a microscope much of the time, the hands-on experience from the MSE department and from my experiences as a research assistant are a huge help in understanding customer challenges and showcasing products to potential clients. The work I’ve done with MultiSEM, which is a highly unique multiple parallel-beam electron microscope, has allowed me to interact with leading researchers at Harvard, Sandia National Lab, and other innovative institutions around the world. I also coordinated sponsorship and served as an industry advisor on an MSE Senior Design project for students doing work that relates to this technology, so the journey from student to mentor has truly come full circle.

What was your time at MSE like?
In terms of coursework, compared to the intro to Bio and Chem courses, MSE student/faculty ratio was very beneficial. I had eight to ten students in a typical class, thus having a one-on-one type relationship with the professors was highly productive. I first got the opportunity to work as a summer research assistant casting metal for Professor Hal Brody. This turned out to be a very enriching and informative experience and one of the main reasons I later took on a research position in grad school.

Why did you choose UConn MSE for your undergraduate and, later on, graduate education?
There were a lot of incentives for me, both in terms of quality of education and overall college experience. The MSE faculty had outstanding credentials, including numerous awards for excellence in education, research, and professional service. They offered hands-on lab courses and sponsored Senior Design research projects to build practical skills. I received scholarships from UConn which made my cost burden as an out-of-state student similar to what I would’ve paid as a Connecticut resident, and later I was awarded a Graduate Research Assistantship which motivated me to continue on. Also given that Storrs is the basketball capital of the world, it was an easy choice with respect to extracurriculars.

How did you first get into materials science?
I’ve always been a big sports gear enthusiast, especially with golf, ski, and snowboarding equipment. I’ve especially marveled at how materials can affect a player’s performance. In high school I took college-prep courses to narrow down my interests as it relates to potential STEM careers. Materials science kept popping up, and UConn was flagged as having one of the few dedicated materials science programs in the northeast at the time [and still]. I never expected that I would get into imaging and spectroscopy, but life worked out that way for the best given my current opportunity with MultiSEM.

What got you into electron microscopy in particular?
Certainly, the MSE program as a whole. The characterization courses involving microscopy always sparked a strong interest in me. As an undergrad and graduate student, I had user access to some fantastic characterization equipment, which I now know is non-standard for many university settings. I worked with Professor Aindow and Professor Carter in my graduate years taking advanced courses on the subject, so feel I got a thorough philosophical and hands-on academic experience in that way.

What compelled you to attend graduate school?
After four years of undergrad I honestly had no intention, however, UConn MSE strongly encouraged their homegrown students to stay and help build the program. The opportunity was too attractive to turn down because I was offered a graduate stipend as a research and teaching assistant, which meant my continuing education was essentially free and I was getting a paycheck every two weeks to boot. Of course, that’s normal now at UConn for Ph.D. students.

What did your graduate years entail?
Grad school took me a total of five and a half years, during which time I served for three semesters as a teaching assistant in the undergrad MSE characterization lab. At a recent IPB event I saw some former students who are now working in industry. It was really fulfilling to see them succeed and use skills I helped pass on. On the research side, I focused mainly on powder processing under the guidance of Dr. Leon Shaw. My master’s project, which was funded by the Department of Energy, involved developing solid-state hydrogen storage materials for mobile fuel cell applications. After two years I transitioned to my Ph.D. project, which was funded by the National Science Foundation, involving additive manufacturing (3D printing) of next-generation biomaterials for orthopedic implants.

What did you do after you earned your Ph.D.?
Before I had even defended my dissertation, ZEISS interviewed me and had a position waiting. When I finished school, I jumped straight into work—it’s hard to believe it’s been five years since then. Moving forward, I feel like I have a lot of opportunities within the company because of the breadth of our portfolio and the breadth of my materials science knowledge. I frequently have the opportunity to travel to ZEISS HQ in Germany, and I have many opportunities to work internationally as part of the greater MultiSEM team. This makes for a dynamic work week to be sure.

How else has the MSE department helped you in your career?
The MSE department is filled with really knowledgeable and supportive people. The experience I had up and down the board, with faculty and staff, with other students, with research tools, has been excellent. Even though MSE has grown significantly since my time, professors truly do try to maintain close personal relationships with students past and present. I learned to communicate, interact, and work within a team effectively thanks to them. It was a top-notch education, and the value of my degree just continues to climb as the department and university continue to rise in the rankings. Working closely with other prestigious universities in the northeast, I can honestly say that UConn is definitely making itself known, particularly in the materials science field.

Graduate student Ayana Ghosh has been honored with the prestigious John Tanaka Fellowship Award for her extensive work and research into Computational Materials Design 


By Marlese Lessing

MSE graduate student Ayana Ghosh has been named as the recipient of the prestigious John Tanaka Graduate Student Fellowship award, which is given annually to a UConn graduate student in the United States’ oldest honor society, Phi Kappa Phi.

The award, which was established in 1993, is named after chemistry professor emeritus and former Director of the Honors Programs, Dr. John Tanaka. Professor Tanaka led Phi Kappa Phi at UConn for many years during his 45 year career at UConn. He also taught inorganic chemistry, and advised many undergraduate and graduate students. Although he passed away seven years ago in April 2012, his name lives on in this prestigious award. 

Ayana said she is “very pleased” to have won the award.

“This type of recognition always acts as a catalyst for me to continue my daily efforts in research, learn more, and perform better,” she said. “I am extremely grateful to receive exceptional mentorship from my advisors at UConn, Pfizer Inc. and Los Alamos National Laboratory as well as my previous institutions that have shaped my academic career to date. I wish to continue performing cutting-edge research on a wide-range of materials with present-day and prospective technological and medical applications while being engaged in events to encourage younger individuals to pursue careers of their choices, especially in STEM fields.”

Candidates for this award are judged based on their research, career goals, academic success, achievement, and rigor, and service and leadership skills and activities. 

Ayana has achieved many of these markers, winning Best Design for her poster in the third annual School of Engineering Poster Session in 2017, and departmental first place in the 2019 competition.  She came to UConn in 2016, starting work in Professor Serge Nakhmanson’s lab working on evaluating Machine Learning methods to accurately predict the crystallization of pharmaceutical compounds, a project funded by Pfizer Inc and UConn MSE.

She is currently studying Computational Materials Design using Density Functional Theory (DFT), Machine Learning and Data Mining in Professor Nakhmanson’s lab. Ayana has previously been a graduate student at New Mexico University. She earned her Bachelor of Science in physics and abstract mathematics from the University of Michigan-Flint in 2015.

“Obviously, I am extremely happy about Ayana receiving this well-deserved award,” Professor Nakhmanson said. “The Tanaka fellowship emphasizes excellence in research and academics, and therefore is a great match for Ayana’s numerous accomplishments. She managed to complete not only a bunch of projects with me, but also collaborated with Pfizer researchers and did multiple internships at the Los Alamos National Laboratory working on something else entirely. She published extensively on all of these efforts and will surely publish more before she graduates.”

In honor of his outstanding excellence in mentoring and supporting undergraduates in the MSE Department, Assistant Professor Seok-Woo Lee has been awarded the UConn Mentorship Excellence Award from the Office of Undergraduate Research.

The award recognizes professors who help develop their mentees’ education and goals through continued guidance, push and support student research and growth, help their students develop a broader understanding of the field they are working in, connect students with resources for research, educational, and career-related endeavors, and overall aid students in becoming well-rounded, educated, and driven scholars within the University of Connecticut.

“This is a great honor for me. This award gives me a lot of meaning much more than any other awards related to research and funding,” Dr. Lee said. “I have worked with UConn undergraduate students for the last four years, and I was always amazed by their positive mind, enthusiasm, and creativeness. I will keep working hard to provide the best MSE education with our precious MSE undergraduate students.”

Dr. Lee has been a part of the MSE Department for five years, joining the department after completing his Kavli Nanoscience Institute postdoc fellow position at California Institute of Technology and earning his Ph.D from Stanford University. He has won numerous awards for his research and teaching, including the UConn Research Excellence Award in 2016 and 2018, MSE Teaching Excellence of the Year in 2017, and the NASA Early Career Faculty Award (CAREER) in 2016. Not surprisingly, he has also received the “undergraduate teaching excellence” four times based on student’s teaching evaluation since 2015 when he started to teach at UConn. He was also selected as the MSE Teaching Excellence of the Year in 2017 and 2018.

His lab, which hosts four Ph.D. graduate students and two undergraduate students, focuses on the mechanical behavior of advanced structural materials at multiple length scales. They are using the state-of-art in-situ nanomechanical testing system to understand the role of crystalline defects in plastic deformation of metals, ceramics, polymers and intermetallic compounds. Undergraduate students in his laboratory usually use an ex-situ nanomechanical testing system and explore mechanical behavior of materials at the nanometer scale.

One of his undergraduate students, MSE senior Hetal Patel, nominated Assistant Professor Lee for the award because of his continued and outstanding support of her and her research throughout her time in MSE.

“Having Dr. Lee as my research advisors is the best thing that happened to me at UConn. He is the highlight of my day and a hallmark of my UConn career,” Hetal says. “Overall, Dr. Lee had changed the trajectory of my career through his kindness, his passion for science, and his dedication towards a student’s success. Coming into UConn, I knew nothing about research, and if I hadn’t met Dr. Lee, I would have never thought of applying to be a University Scholar, have decided to pursue a Ph.D. or would be going to a top graduate school.”

Dr. Lee was honored at the Frontiers in Undergraduate Research Poster Exhibition reception on April 12, 2019. Hetal Patel gave a poster presentation for her work on the effects of tip radius on mechanical behavior of single crystal tungsten under spherical nanoindentation. Hetal Patel’s speech for Dr. Lee’s mentorship is available at the webpage of UConn Mentorship Excellence Award

Frontiers in Undergraduate Research is an annual poster exhibition of student research, scholarship, and creative projects. Frontiers is a chance for students to share their work with the UConn community and with visitors to campus. This is one of the largest events for UConn undergraduate research, which several hundred undergraduate students from the entire campus participate in.

MSE alumna, Dr. Jacquelynn Garofano

A highly accomplished and distinguished MSE alumna, Dr. Jacquelynn Garofano (M.S. ’09, Ph.D. ’11), has been named Program Manager of the prestigious Margaret Ingels Engineering Development Program at United Technologies (UTC). The program is named after Margaret Ingels, the first American woman to receive a professional degree in mechanical engineering (B.S. 1916; M.S. 1920, University of Kentucky) and the first female engineer at Carrier where she spent a distinguished technical career and was a close associate of Willis Carrier.  

Jackie began her career at UTC as a senior research scientist at the Research Center (UTRC) in 2011. For more than seven years, she worked to solve technical challenges, provide failure investigation and develop innovative technologies for UTC’s aerospace and building industries, leveraging her materials engineering expertise. Now, she draws on her solid technical foundation, leadership competencies and social impact to lead UTC’s newest leadership program.

“In my new role, I have the privilege of cultivating and leading the next generation of engineers who will shape our future. I can’t wait to welcome our first cohort into UTC this June!” Jackie said.

The Ingels program is a two-year, entry-level engineering development program designed to build engineering, leadership, and business acumen through a challenging, fast-paced rotation experience. Program associates will receive a holistic view of United Technologies through four six-month rotations at Pratt & Whitney, Collins Aerospace and UTRC across engineering disciplines that exposes them to the product life-cycle: design, manufacturing, testing & validation, operations, delivery, and so on.

Jackie is responsible for recruiting top engineering talent for UTC and is actively seeking engineers for the second cohort, which starts in 2020. In addition to the Ingels program management, she says, “I also have an opportunity to support UTC’s strategic initiatives in STEM education and workforce development to ensure that we are fostering a diverse and competitive technical engineering workforce and pipeline.”

Dr. Garofano was named a 2011 Women of Innovation by the Connecticut Technology Council, as a recipient of the Collegian Innovation and Leadership Award, capping off an exceptional career at UConn. Early in her professional career, she earned the unique distinction of landing on the Forty Under 40 outstanding young professional list for Connecticut Magazine (2013) and Hartford Business Journal (2015). Most recently, she was recognized as a 2018 Future is NOW awardee by the CT Women’s Education and Legal Fund for her work to advance women and girls in the STEM field.

Congratulations to Jackie for all her accomplishments, for promoting the next generation of emerging leaders in engineering and, above all, for being an exemplary leader for the Margaret Ingels program.

By Marlese Lessing

Senior student Joseph Podbielski spends his school days helping manage labs for engineering students, and his summers helping design helicopters for Sikorsky. An Avery Point transfer and a Mystic native, Joe’s dream is to work at Sikorsky like his father.

His supervisor for the lab, Francis Almonte, calls Joe a “natural leader” within the MSE department.

“The best students are those who demonstrate academic success and pursue information. The best leaders are those who exhibit an initiative to learn and real energy to serve the community,” Francis says. “Joseph is a natural leader whose persistent habit is volunteerism, and through these efforts he has gained a level of mutual respect from UConn’s Materials Science and Engineering community.”

We sat down for an interview with Joe about his experiences in the MSE department as both a student and an experienced lab technician.

How did you become interested in materials science?

My dad was an engineer for Sikorsky, and as a kid I was always playing with Legos and K’NEX. My dad always pushed towards that and encouraged me to pursue it.

For me, it was when I took ‘Mechanical Behavior of Materials’ with Dr. Seok-Woo Lee and Adam Wentworth, who was my lab instructor. In that class, we were getting into real-world scenarios and doing hands-on experiments. Both of my teachers were excited about what they were teaching, and that rubbed off on me. My personal favorite module from that lab was when we did a geopolymer project and used a custom concrete blend to try and reduce CO2 emissions. I feel like I apply what I learn in class right out the door. I’ve always loved working with my hands, working with stuff and fixing things. I’d definitely like to go into mechanical behavior, seeing why things break, how they can break and how they can be improved.

How did you find a way to stay in the lab?

Last fall I started working as a laboratory technician for the undergraduate labs. I also work as a teaching assistant for Dr. Volkan Ortalan in his Mechanical Behavior class. Right now, his students are testing the mechanical properties of wood, and the tensile properties of certain types of guitar strings. I help prepare samples, run the samples and collect data. For the undergraduate labs, I help prepare modules and labs for the students. I now spend about 15-20 hours a week in the lab on top of a full class schedule, which I manage with a lot of coffee!

What do you enjoy about managing a lab?

I get good attitudes from the students I work with. Generally, they’re very excited to get into the material. In the junior labs, they’re given a lot of freedom—they have a material they’re working with, and it’s up to them what to do with it, how they’re gonna test it. I just guide them. It helps foster a positive attitude. I do my best to get them enthusiastic and help them enjoy the experience.

I also love using the mechanical testing machine. We use the dog bones and see how a material can withstand stress. It’s really cool seeing what something can take and how it breaks.

Which professors and mentors have helped you in your journey?

Adam Wentworth, for sure. Dr. Lee and his excitement for MSE has truly inspired me. I get to work with people who are excited to do what they do, which is a motivating experience. It helps to have people who are enthusiastic about they do. All of my lab classes have been extremely helpful, since it’s something you can see and apply to your work. At one point, I was helping Dr. Lee do some research, and he had thumbtack-sized cylinders of magnesium. We were doing strength tests on them, and it was amazing how much weight these tiny little cylinders could hold—thousands of psi.

Tell me about your work with Sikorsky.

I’ve interned there every summer since my freshman year, in 2015; I think I’ve logged about 600 hours every summer since I’ve started there. I started doing basic design checks for the helicopter parts. The senior engineers would draw up designs and send them over to me, and I’d check them for any errors before sending them off to our boss. Now, I draw the designs myself, and help train new interns to do design checks like I did. We’re working on ways to upgrade the aircraft we’re producing. I’ve worked on Blackhawks, Seahawks, and some commercial aircraft.

It’s something I enjoy. To actually be handed responsibility and have a say in aircraft that people will use for decades to come, it’s unique. My coworkers are wonderful to work with, and it’s awesome to see the designs I helped put together as they literally take off. During Lockheed Martin day, I got to see one of the helicopters I worked on, a Blackhawk, and I talked to the flight crew who had just flown in from North Carolina after rescuing people from the recent hurricane. Seeing that, and seeing people use the mechanics I worked on, which have had an impact on people, well, that has been priceless. I hope I can work full-time there after I graduate.

What advice would you offer to undergraduates looking for an internship like yours?

Apply yourself. Talk to your professors, talk to industry people. Senior Design really helps, especially if you do a good job and show a good work ethic.

What is one challenge you had to overcome during your time in the MSE Department?

Moving away from home. I used to commute to school at Avery Point and go home every night. When I moved here, it was a new place, with new people, and a brand-new world. I was a little overwhelmed, but I buried myself in my work and my studies. I spent as much time as I could in the lab and got to know as many people there as I could. Now I always have a home in the lab. I have a great group of lab mates, and I’m happy to be a part of it.

Zach Stone was one of the first undergraduate students to join the Materials Science and Engineering program back in 2001. Starting with a class of only five students, his skills in metallurgy landed him work with Sikorsky and UTC Aerospace Systems. Now, he works at Vuzix Corporation, one of the leading companies in breakthrough augmented reality technology, paving the way for new innovations in the video game, medical, business, and educational fields. Recently, he appeared at the UConn Science Salon series to discuss the future of AR and VR with students and faculty.

What started you off on materials science?

I originally started in computer science, which I quickly realized I was woefully unprepared for. At the time, UConn was trying to get their materials science program up and running, and I decided to give it a try after seeing some of the demos they had on display during an informational meeting. In my graduating class, there were five people, which meant there was a great student-professor ratio. We were all really close, and I still keep in contact with everyone I graduated with.

What appealed to you about the program?

We had a truly unique experience. Like I said, we had a low student-to-teacher ratio. The professors were developing the courses as we went along. I felt like everyone wanted this undergraduate program to succeed, and we rose to the occasion. The classes were tough, but we learned so much from them.

One of my favorite courses was our casting course. We were casting aluminum in one of the physics buildings, and the casting facility had all these CRT monitors around it. When we worked on the aluminum foundry, the magnetic field would distort all the monitors and they’d have to turn them off. So every time we melted aluminum, everyone in the building would get mad at us.

What were some unique experiences you had in the program?

In my senior year, I undoubtably learned to step outside my “safe zone,” so to speak. My senior design project was studying recycled aluminum and removing impurities from it, like iron and steel contamination.  This is genuinely important for airplane and automobile recycling and reprocessing. We took bars of aluminum and tried different methods to remove impurities. It was me and one other student, and we were sponsored by Bodycote, a metallurgy company. Our research did end up having an impact, and I believe Bodycote even sponsored follow up projects with UConn to verify our findings. 

Where did you go after UConn?

I was at Sikorsky for five years as a member of the failure analysis team. Later on, I was with UTC in their Operations Leadership Program for two years, and then as a materials manager in Orange County, California. In 2008, I went to the University of New Haven for my MBA/MSIE. After working in the world of engineering for a while, I got the opportunity to work with a startup company in Rochester, Vuzix. That was three years ago. I started as a quality manager for products, but I’m now vice president of operations there.

Tell me about your work.

Our products are augmented reality (AR) glasses. We implement video and camera technology into wearable items, allowing people to see through a camera or into a video input. One of our products, Blade, is a pair of sunglasses that pulls up your phone apps, call and information right in front of your eyes, so you aren’t looking down at your phone all the time.

How do you bring materials science into it?

One of my current jobs is overseeing the supply chain and manufacturing of the products we sell. Part of the reason I’m able to do what I do is because I have a strong engineering background. It’s a whole mindset behind how you can use the materials at hand to make what you need. So, I can look at costs, strengths and weaknesses, implementation, and the overall effect a material can have on the product. I use these advanced material concepts to my advantage—and, of course, it helps to have a broad base. It’s been a lot easier that way, for me to expand into different roles.

What influenced you the most during your time in the MSE department?

Definitely my advisor, Dr. Brody. He taught me how to be flexible and how to roll with the punches, which has been critical throughout my time in the department and after I graduated. My time as a student was a nonstop group of challenges that I had to adapt to, and that level of demand shaped me and how I handled it. Really, though, every professor I had was engaged in our success. We got a lot more facetime than most students, which I hear is still the case now for current MSE students. I look back at my time there fondly. It really was a good program.

Author: 40 Under 40 Entrepreneur Uses Engineering Skills To Bring People Affordable Glasses

By Marlese Lessing

The daughter of an optometrist and a Farmington native, MSE alumna and Connecticut businesswoman Stephanie Higgins Bealing is using her materials science and engineering experience to push the gauntlet on the eyeglasses industry, winning her numerous awards, getting herself named as one of Connecticut’s 40 under 40, and netting her national recognition for her business, Replacement Lens Express. Her previous jobs have included being a fuel cell engineer for Rolls Royce, a technology developer for UTC Aerospace and a project lead for an MCHX coating project at Carrier Corporation.

What inspired you to get into engineering?

I was really into Stephen Hawking as a kid. My dad definitely pushed me into the sciences, and after I graduated high school, I got a degree in physics, with a focus in geophysics, from Hamilton College. I got the opportunity to go to Antarctica and study the geochronology of underwater volcanoes through the United States Ocean Drilling Program, using alpha-decay spectroscopy. We actually discovered a new underwater volcano on that trip. 

While I was in college, I took a class in ceramics, and it inspired me to learn more about the physical and engineering aspect of it. I wanted a college with a good engineering program and that was close to home, so UConn was ideal. I pursued my masters in solid oxide ceramics soon after I got my Bachelor’s, in 2004.

What struck you about your time at the MSE department?

I was here for two years, but I got to work with so many excellent people. I worked as a graduate assistant at the Connecticut Global Fuel Cell Center (now C2E2), and it was a wonderful master’s experience. The faculty opened up so many opportunities for me, especially to travel internationally and collaborate with some of the top industry experts in the field. I got to visit Imperial College in London for a conference about solid oxide fuel cells.

Professor Mark Aindow and Professor Pamir Alpay were both especially helpful. They connected me with a large range of people in the field, which helped me land a job working with fuel cells for Rolls Royce in London, and later with UTC Power (now called UTC Aerospace). When I graduated in 2006, I left UConn MSE with such a great mindset about industry and collaboration.

What are some of the other resources the MSE Department offered you?

I was blown away at the exposure and opportunity I was offered. I felt like I was an entrepreneur with my projects. I got to design my master’s thesis project as I wanted to, and work with measurement equipment that I never could have imagined getting access to. I made a ton of great connections and got a lot of lifelong exposure to a field that holds a very dear place in my heart.

At one of the conferences I was sent to in Denmark, I was asked to talk about my master’s thesis in solid oxide fuel cells. I got to network and talk about my project with some of the top people in the field, which was incredible.

Where are you right now?

After working in the engineering world for a while, I decided to pursue my master’s in business administration from Carnegie Mellon University in 2008. In 2010, I launched online, home-delivery eyeglass lens replacement service, Replacement Lens Express, as a side-project. The popularity exploded after just one year, and I continued to pursue it to this day.

The company offers prescription glasses at an affordable rate to people who need replacement lenses. The prices are 30 percent less than commercial prices for most major brands, and we’re even offering our own in-house lens. We’re the only female-owned online optical lens company, and we’re bringing in a great amount of new and repeat customers in over 55 countries. It’s a new way for people to get affordable glasses.

How did your experiences in the MSE Department help you get to that point?

My master’s experience really taught me how to put myself out there, to be assertive and to stand up for myself. As a businesswoman now, it’s a crucial skill.

Dr. Aindow’s microscopy class was also a great help. It was very writing-intensive, and he wanted to help us, the students, improve our writing. It helped me learn to communicate my ideas clearly and effectively, which is a skill I use all the time now.

Materials Science and Engineering graduate students let their communication and presentation skills shine at the 2018 Fall Graduate Student Speaking Competition on Friday, Nov. 16. Four students, Benjamin Bedard, Douglas Hendrix, Thomas Moran,and Tyler Flanagan, were selected by the MSE Graduate Committee to participate in the annual contest, which is part of the MSE Seminar Series.

Each graduate student had 12 minutes to present his topic, with time given for questions form the judging panel afterwards. The graduate students were evaluated based on their presentation’s quality, scientific and engineering merit, originality and other criteria by a panel of three faculty members and two graduate students.

Douglas Hendrix, an MSE Ph.D. student who graduated from UConn in 2015, emerged victorious, taking first place with his presentation on “Characterization of Dispersion Quality of Nanoparticles in Cementitious Materials.” He is currently studying the effects of nano-sized particles in cement, co-advised by Professor Bryan Huey and Associate Professor Kay Wille from the Department of Civil and Environmental Engineering.

“The quality of all 4 of the presentations impressed me the most. Each speaker succinctly described their research, made it interesting to the audience, and answered questions with authority,” Professor Huey said. “In fact, these talks would fit in perfectly at any major materials conference, and thus set a great example to the students in the audience. I’m especially pleased for Doug whose work is inherently interdisciplinary, as is much of what we do in MSE.” 

Congratulations to Douglas, and to those who participated in the competition!

From Undecided to Dean of Engineering at Michigan Tech

Author: Alumna Alexandra Merkouriou Talks Outreach, Career, and Semiconductors

By Marlese Lessing

Alexandra Merkouriou

MSE alumna Alexandra Merkouriou, Development Engineer at M Cubed Technologies

After graduating with a B.S. from the materials science and engineering program at UConn in 2015, Alexandra Merkouriou went on to complete the Edison Engineering Development Program at GE Industrial Solutions. She currently works at M Cubed Technologies making silicon carbide ceramic composites for the semiconductor industry and has returned to UConn part time as a graduate student to pursue her M.S. in materials science and engineering. She accredits her success and passion for materials science to her professors here at UConn and her colleagues at her current workplace. Alexandra was recently invited to join the MSE Industrial Advisory Board.

What projects do you currently have running?

I’m working on a new product introduction for a product that will help create higher density flash memory. This product is a great opportunity not only to work with the custom to develop a successful design, but also to push the boundaries of precision manufacturing.

I’m also developing a diamond silicon carbide material called Thermadite. I’m fortunate enough to be working on characterization of a new formulation of Thermadite. Hopefully soon after that work is completed, we’ll be able to slowly introduce it into the industry. It’s really great to see my research applied in the industry almost as soon as I discover something new.

My Master’s project is through my company, which is great, and very busy. It’s a balance of working and researching. My thesis is due at the end of the year, so it’s very much crunch time for me right now.

 What inspired you to join the MSE Industrial Advisory Board?

Professor Bryan Huey invited me to the Industrial Advisory Board earlier last year. I had participated briefly in some Industrial Advisory Board student feedback meetings as an undergrad and I was honored to be able to be part of the committee. Our goal is to help guide the Materials Science and Engineering program and provide insight into current and future industry needs and expectations. I have always enjoyed finding the opportunities that allow me to help others grow in their careers and being part of the Industrial Advisory Board gives me the chance continue that work and also to give back to the program (UConn MSE) that has gotten me to where I am today.

How did you first get into materials science and engineering?

In high school, I found out about UConn’s Explore Engineering program over the summer. It was a week-long program where they introduced me to all the different fields of engineering offered here at UConn, and I was immediately drawn to the materials science portion of the program. One of the demos they showed us was a superconductor. As soon as I saw the magnet hovering in midair I was hooked, I knew I had to do that right away. After talking to Professor Huey, who ran the demo, I worked in his lab during my undergraduate career. 

What experience do you think has influenced you the most at the University?

Alexandra Merkouriou (sixth from the left) meets with Governor Malloy to celebrate the final approval of Next Generation Connecticut legislation in Oct. 2013. MSE students were excited to meet Malloy and conducted experiments in magnetic levitation using ceramic superconductors produced in MSE undergraduate labs. (From left to right) Zachary Thatcher, Nathan Martin, Rheanna Ward, Governor Dannel P. Malloy, Alexander Reardon, Alexandra Merkouriou, Nicholas Poulos, Steven Onorato, Dr. Bryan Huey, Terry Ng.

I was part of UConn Material Advantage, an outreach club that talks to high school and middle students about engineering and the sciences. I loved teaching younger kids about the world of engineering and STEM, and showing them the opportunities available to them as scientists and engineers. I started in my freshman year, and I was lucky enough to be elected President for my last two years until I graduated. I saw this position as a way to help members make connections and networking collaborations that could help them with their future careers. My hope was to communicate all the things I wish I had known going into engineering – like when, how and where to look for internships or undergraduate research, how to make a resume and what to expect from an interview. 

One experience that was very important to me was tutoring two seniors at South Windsor High School in materials science and engineering for a STEM competition they were competing in. I came up with lesson plans incorporating some of my demos from Material Advantage and gave them an introductory lesson to a lot of the topics in our introductory materials engineering classes.  I loved the teaching aspect of it.

Who helped influence your path at the Department?

There are so many professors that helped me get to where I am now. Working with Professor Pamir Alpay was great. I met him through Material Advantage because he was the department head at the time. He helped guide me through the program and opened up so many opportunities in terms of my career.

Dr. Daniel Goberman taught the first materials class I ever took and showed me that materials science can always be exciting. He works at Pratt and Whitney Research Center. He did an excellent job of introducing us to materials science and telling us why it matters, how it influences our lives and peoples’ lives, and how we can change the world that way.

Even though some of my classes weren’t easy, I use what I learn in them every day at my job in M Cubed Technologies. Professor Brody taught two of the hardest classes in the MSE course set, thermodynamics and materials transport. He also did a fantastic job of connecting it to industry and market needs. Professor Aindow in my senior year also gave a phenomenal class on materials characterization. As a materials engineer, it’s so important to know the tools you have at your disposal. It’s had such a huge impact on my work.

What advice would you give to yourself from four years ago?

Make mistakes now. It’s ok to fail, it’s ok to change your mind. UConn has a huge support system to help you when you fall. I’m using everything I learned from my mistakes and failures in college, and the support system at the MSE department helped me pick myself up again and go back at it. It’s such a huge booster to have something like that, but it’s one of those things that you don’t realize you have until its gone.

In sum, how do you think the MSE department helped you to your current career?

The Department has been my home throughout my undergraduate career. I got to test my limits as a scientist, learn how much I love research and forge a path to a career I’m in love with. They were a phenomenal support system, all the professors, all the office staff. When I come back here, it’s a sense of freedom. I know there’s people who are here who will let you try just about anything. It’s been such an encouraging environment.

Author: 2018 ASM Conference Allows MSE Undergraduates to Meet and Compete

By Marlese Lessing

The 2018 Materials Science and Technology (MS&T) Conference in Columbus, Ohio brought thousands of scientists and innovators from around the globe to celebrate and collaborate on the latest breakthroughs in materials science. Perhaps most excited of all were 10 UConn MSE undergraduates who attended the event both to represent UConn and to take part in the myriad of activities the conference offered. This included Kenna Ritter, Hetal Patel, Grace Quinlan, Iwona Wrobel, Michelle Such, Zach Putney, Joe Tracey, Jordan Gomes, Alex Perkins, and Justin Hewitt.

Senior Kenna Ritter, president of the UConn Materials Advantage chapter and member of the ASM International Student Board of Trustees, helped draft plans for the student board to provide more resources to MSE students who are part of ASM International. She also helped organize the 2018 Domesday Competition, which invited students from several prestigious universities to bring their best ‘dome’—a structure built to withstand compression. Points are also awarded for aesthetics, durability, design,and other criteria. UConn’s Justin Hewitt, Jordan Gomes, Iwona Wrobel and Zach Putney all took part with their polymer-based structure.

Joe Tracey and Hetal Patel competed in the Undergraduate Speaking Competition and the Poster Presentation Competition, respectively. These contests reward the presenter for the scientific content,  public performance, and the author’s composition skills. The Keramos Ceramic Mug Drop, for which Alex Perkins and Grace Quinlan made (and sacrificed) ceramic mugs, tests ceramics skills by dropping lab-designed and crafted mugs from progressively greater heights. Until they break…

The Keramos Ceramic Frisbee Competition, however, is where UConn truly shone. Michelle Such’s midnight-dark frisbee won first place for the Aesthetics competition among all of the universities competing at this annual MSE conference. This was followed by the ceramic Frisbee toss, judged on a strange combination of resilience and aim, in which Zach Putney, among others, naturally competed since he’s also a member of UConn’s ultimate Frisbee club.

“UConn MS&E has a proud history of our students winning recognition at MS&T and other scientific conferences,” says department head Bryan Huey. “We are very pleased to cosponsor this annual undergraduate delegation, especially since the officers and members of Materials Advantage work so hard year-around with outreach, recruiting, programming, and social events. “

As one of the four major annual meetings for the MSE community worldwide, UConn’s undergraduate delegates also mingled with like-minded engineers, faculty, and students from all corners of the globe. Conferences like these enable engineers to learn how others tackle academic and real-world problems, network with each other, and gain leadership skills.

“Students were also able to attend normal conference proceedings and attend talks on a wide variety of materials topics,” Kenna said. “We were able to network with students from other colleges and universities at various social events that were held throughout the week.” 

Says professor Huey: “To me, the best part of a conference is being reminded of just how broad, how important, and how interesting is the field of materials science. There is no shortage of challenges to solve, clever solutions, or career paths.”

The STEAM (Science, Technology, Engineering, Art, and Mathematics) Night is the annual event that invites more than 200 elementary school students and immerses them in the exciting world of STEAM, taking a multifaceted approach in order to encourage young thinkers to work and collaborate across the disciplines.

The Material Advantage Student Chapter ran several demonstrations, showing the students the weird and wonderful ways different materials can be manipulated.

Their famous liquid-nitrogen frozen marshmallow trick drew a crowd. The undergrads dunked the sweet treat into a nitrogen bath and shattered it in front of the students’ eyes, showing how temperature can affect the structure and behavior of an everyday material.

The group also demonstrated how certain metals can become liquid—without the need for a smelter or a blowtorch.  Gallium is liquid at 30°C, and will melt in your hands, which drew gasps and giggles from the students. MSE Advantage’s 3D printed figurines also attracted kids with their innovative custom designs.

Dr. Seok-Woo Lee helped the kids visualize the world of the microscopic by having the students build 3D crystalline structures. Using marshmallows and toothpicks, the students started with the structure for graphene. However, after some additional construction, it morphed into a very complex, very sweet and yet-to-be-discovered crystalline structure.

Other groups that participated included the UConn Farmington Health Center and the Farmington High School Robotics team, who used their know-how to, along with Material Advantage, help foster the builders, shakers, and movers of the future.

Garvit Agarwal is a Ph.D. student studying atomistic and mesoscale modeling of dynamic defect structure evolution during high strain rate loading. He is the recipient of the 2018 Graduate Student of the Year Award, for his exceptional work and dedication to the field of materials science and academic excellence since he joined us in 2014.

“I feel really honored to win the graduate student of the year award,” Garvit said. “I am extremely thankful to my adviser, Dr. Dongare, who not only gave me the opportunity to work on the novel research project but also constantly guided me and taught me a lot of things during the past four years of my graduate career at UConn.”

Associate Professor Avinash Dongare, Garvit’s advisor, said Garvit’s passion and work ethic helped contribute to his accomplishments.

 “It’s great to see Garvit mature and grow as a researcher over the last four years,” Dr. Dongare said. “He is very passionate about learning new skills and is keen to put in the hard work required. It is very important for students to get as much exposure as possible while they are still in graduate school and Garvit is certainly making the most of it. His hard work and perseverance has opened up a lot of opportunities for my group to collaborate, and he is a leading researcher in the making. He certainly deserves the Graduate Student of the Year Award.”

Garvit was given the award after being chosen by a group of faculty and staff for his outstanding work in the field, which focuses on atomic scale and mesoscale modeling of the deformation and failure behavior of metallic materials under shock loading conditions.

This photo is of Garvit’s research subject, which depicts the capability of L2-QCGD and L4-QCGD to accurately capture the wave propagation and spall failure behavior of 100 nm grain sized polycrystalline Al microstructure subjected to impact loading at a piston velocity of 1 km/s.

This photo is of Garvit’s research subject, which depicts the capability of L2-QCGD and L4-QCGD to accurately capture the wave propagation and spall failure behavior of 100 nm grain sized polycrystalline Al microstructure subjected to impact loading at a piston velocity of 1 km/s. The MD simulation consisted of ~700 million atoms while the same system is modeled using only ~89 million R-atoms in L2-QCGD and ~11 million R-atoms in L4-QCGD. The reduced number of R-atoms allows for modeling system sizes at the micron length scale at a fraction of computational cost using the QCGD method.

“The most interesting thing about atomistic modeling techniques like molecular dynamics (MD) simulations is that it gives us the capability to design experiments virtually on a computer screen and study the effects of different operating environments in a systematic way,” he said. “It also gives us greater flexibility and the ability to study phenomena at the atomic resolution which are difficult to study using experiments.” 

He joined UConn in 2014 to pursue his Ph.D. here at the Department of Materials Science and Engineering.

“In four years of my graduate career at UConn, I got numerous opportunities to attend conferences as well as visit national labs such as the Army Research Laboratory and Los Alamos National Laboratory,” Garvit said. “It allowed me to interact with a number of scientists and researchers from diverse backgrounds which gave me greater exposure to cutting edge research and state-of-the-art research facilities which is really important for a graduate student in order to grow into a successful researcher.

Garvit earned his Bachelor’s in metallurgical and materials engineering in 2011 from the Indian Institute of Technology in Roorkee, Uttarakhand. After he graduated, he worked at Jindal Steel and Power Limited, an India based steel plant, as Assistant Manager, before moving to the United States in 2014.

During his time at UConn, Garvit had to pick up a totally new skillset in order to pursue his research in materials modeling. 

“Since I had no previous training/background in the field of atomistic modeling of materials, I not only learned a lot of fundamental material science concepts but also developed good analytical and programming skills,” Garvit said.

“I believe that it is a really fascinating time to be in the field of computational materials modeling. The progress in computational modeling methods are accelerating researchers’ ability to accurately predict the properties of new materials even before experimentally synthesizing them,” he said.

After earning his Ph.D., Garvit said he plans to continue pursuing knowledge and excellence in the field.

“I wish to continue doing research in field of computational material science and I am actively looking for postdoctoral opportunities,” he said. “The department of material science and engineering at UConn offers a unique mix of experimental and computational faculty members which opens up opportunities for a number of collaborations within the department. All the faculty members in the department are very helpful and motivating and the interactions with them has really helped me grow and develop as a researcher and student.”

Undergraduate students from the department of Materials Science and Engineering proved victorious in a friendly soccer match against Chemical and Biomolecular Engineering (CBE) undergraduates on Sunday, as the two groups competed and mingled with each other given the overlap in their majors.

The game, organized by student outreach clubs UConn Material Advantage (UCMA) and the UConn chapter of American Institute of Chemical Engineers (AlChE), helped the students in both organizations learn more about each other, said UCMA president Kenna Ritter.

“We figured that Chemical Engineers and Materials Engineers have a lot of similarities between our fields so joint events just made sense to us,” Ritter said. “We happen to have some competitive people in our major too, so both clubs jumped at the chance for a friendly game.”

Department Head Bryan Huey showed up to enjoy the competition and, in the end, celebrate the victory.

“It’s natural for MSE and CBE to meet up over an oversized Bucky ball, since traditional soccer balls look just like a C60 molecule, Huey said. “Probably the best part of all was how this connected students four years apart, across majors, and drew men and women on both sides. Next time we’ll see what sport gets arranged—and instead of sitting at the sidelines, I might even sub in. Regardless, I hope this will become an annual tradition—winning the trophy, that is.”

Ritter worked with AIChE president Alex Olivera to put together the event, which attracted students from freshman to senior years. She added that with the success of this weekend’s game there will be more collaborations to come between the two groups.

“I was especially happy to see a lot of freshman come, I love seeing people get involved with clubs early on in their time at UConn,” Ritter said. Undergraduate MSE senior Justin Greenwood and undergraduate CBE senior Michael Castelpoggi were instrumental in getting this game started. Alex and I both hope to plan more joint UCMA-AIChE events this year- social or otherwise. Everyone had a great time!”

Author: MSE Faculty Article on Piezoelectric Ceramics Featured in August 2018 MRS Bulletin

MRS Bulletin CoverBy Marlese Lessing

MSE professor Dr. George A. Rossetti, Jr., in collaboration with Dr. Dragan Damjanovic (Swiss Federal Institute of Technology in Lausanne), has published an article in the August 2018 issue of the Materials Research Society (MRS) Bulletin. The paper, “Strain Generation and Energy-Conversion Mechanisms in Lead-Based and Lead-Free Piezoceramics,” analyzes the origins of piezoelectric activity in technologically important ceramic materials used as actuators and sensors. Concepts discussed in the paper are featured on the journal cover.

Piezoelectric ceramics (piezoceramics) convert electrical into mechanical energy, and vice-versa. They are found in many products encountered in everyday life, including spark igniters, buzzers, ultrasonic cleaners, inkjet printers, fuel injectors and medical ultrasound diagnostic equipment, just to name a few. They are also vital to the sonar systems used in submarines and other undersea vehicles.  

For over 60 years, the most important piezoceramic materials have been based on the ferroelectric solid solution lead zirconate-titanate (Pb[Zr1-xTix]O3or PZT). About 15 years ago, however, legislation in Europe and elsewhere restricting the use of lead-containing materials in electronics triggered an effort to find lead-free piezoceramics that could replace PZT in many, if not all, applications.

Doing so has proved to be a difficult task. The mechanisms of piezoelectricity in ceramic materials involve complex electrical and elastic interactions spanning length and time scales, from intrinsic mechanisms involving the motion of atoms within a unit cell, to extrinsic mechanisms involving the motion of ferroelectric domain walls. The lone-pair ion Pb2+ in PZT is a key factor in its superior electromechanical performance, since it produces a large distortion of the unit cell, enhances the material’s electric polarizability and increases the stability of the piezoelectric properties to changes in temperature. Because lead is so unique in this way, it’s hard to duplicate its advantages with other materials.One strategy for achieving high piezoelectric activity in lead-free ceramics is to exploit intrinsic mechanisms involving the extreme softening properties that occurs near structural phase transitions, wherein the electric polarization vector changes from one crystallographic direction to another.

For example, in lead-free solid solutions emulating the phase diagram of PZT, such as barium-calcium titanate-barium zirconate-titanate (BCT-BZT), compositions near the tetragonal – orthorhombic phase boundary produce strong increases in shear elastic compliance and transverse dielectric permittivity that result in piezoelectric coefficients exceeding those in many lead-based systems. 

Another strategy involves doping lead-free materials with carefully chosen ions that can modify the mobility of ferroelectric domain walls. The dopants may either enhance domain wall motion and increase the strain response, or impede it and reduce energy losses. Doping can thus improve the piezoelectric properties for particular applications, such as for actuators where a large mechanical strain is needed, or for high-power, high-frequency transducers where improved electromechanical energy conversion efficiency is more important.

These approaches have so far been only partially successful. As with lead-based piezoceramics, there are tradeoffs that may prevent the substitute material from being used in certain applications. The MRS Bulletin article by Damjanovic and Rossetti provides a detailed analysis of what has been learned so far regarding the mechanisms of piezoelectric activity in ceramic materials – and clues for promising areas of future research.
