Welcome Message from the Department Head Dear MSE alumni, students, parents, and friends, As another academic year is underway, I am pleased to share many recent accomplishments of our department’s students, faculty, staff, and alumni. In May, we celebrated the achievements of our most recent graduates at the MSE Diploma Ceremony. Seeing this new group of MSE alums who are so very bright, determined and excited to start their next chapter after much hard work is always a joyful event. Many of the graduates are continuing their education and moving onto M.S. and Ph.D. programs, while others have chosen to enter the workforce at companies including Pratt & Whitney, Texas Instruments, Microvast, Apple, Intel, Samsung and the Lawrence Livermore National Laboratory to name a few. No matter the path they are on, we know they will do great things with the foundation they received in MSE at CMU. Our MSE faculty and students continue to expand the forefront of materials science research, as evidenced by new multidisciplinary research programs highlighted in this issue of our newsletter, including the NASA Space Technology Research Institute for Model-based Qualification and Certification of Additive Manufacturing led by Professor Tony Rollett. We are also excited to highlight Professors Cohen-Karni’s and Feinberg’s research on self-sustaining bio-actuators within a new Department of Defense Multidisciplinary University Research Initiative (MURI), and Professor Pistorius’ research on steel manufacturing decarbonization in collaboration with Professor Valery Karplus in CMU’s Department of Engineering Public Policy. These research initiatives, among others highlighted in this newsletter, showcase the incredible creativity of our faculty, and these programs provide our students unique and rich opportunities to drive cutting-edge science and engineering. As our students take what they learn from their education into the world as alumni, they continue to innovate in a variety of fields. I think you will enjoy hearing about the incredible achievements of several alumni featured in this newsletter. As I continue to interact with our alumni community at events such as Spring Carnival and the Saltminers’ Dinner, I am impressed by their individual and collective accomplishments and readiness to assist fellow alumni and students. The members of our Alumni Advisory Council featured in this issue highlight the dynamic cross-section of the careers that our graduates pursue. I encourage our alumni to shine a light on their successes within our CMU MSE community, whether by emailing us, mentioning our social media pages, or sharing a post on our LinkedIn Alumni group. By sharing your successes, you inspire our students, the next generation of materials science leaders, to pursue a variety of career and research paths. Thank you for your ongoing interactions with and commitment to the MSE department at CMU and as another year comes to a close, I wish you all a joyous and happy holiday season and a healthy and prosperous 2024.
Sincerely,
Beth Dickey Teddy & Wilton Hawkins Distinguished Professor and Department Head of Materials Science & Engineering

desired properties and performance can be achieved. The MCF provides a series of state-of-the-art tools that allow researchers to visualize the internal structure of materials at very high spatial resolution, which enables them to understand and eventually improve material behavior. “The past 25 years have seen a tremendous increase of computerized characterization tools which benefit all MCF users,” said Marc De Graef, Faculty Director of the Materials Characterization Facility.
“This collaborative model, which has been very successful at attracting users from local industry and research labs, will continue to impact local industry by making advanced X-ray characterization capabilities available,” said De Graef. The Xeuss SAXS 3.0 boasts automation capabilities that include robotic sample handling for high-throughput data acquisition in solution studies and the ability to utilize remote operation. Additionally, multiple sample holder options are available for powders, solids and gels as well as a multi-refillable capillary holder with temperature control (10°C to 80°C).

While offering conventional micro Computed Tomography (CT), the ZEISS Xradia CrystalCT® is a crystallographic imaging system that can transform the way polycrystalline materials, such as metals, alloys, and ceramics can be studied, as it can map larger volumes and a wider variety of sample geometries at higher throughput. “Researchers can see the internal structure of materials non-destructively with the CrystalCT system,” said MCF Managing Director Betsy Clark. “They can perform an experiment, for instance a heat treatment, and then come back to the instrument to see how the microstructure changed by a simple direct comparison.” While the MCF provides extensive research support, the equipment available in the facility also offers a range of training opportunities for students across engineering disciplines. “A student can learn a great deal in this space because X-ray diffraction involves crystallography, microscopy covers imaging, and between the two, you really apply a lot of material sciences concepts on a wide range of equipment,” said Jason Wolf, who held the role of x-ray lab supervisor in the facility from its opening until 2015.

These procedures can be painful and require anesthetics, limiting how frequently they can be performed. Ingestible sensing capsules that perform diagnostic tasks as they travel through the digestive system are a promising alternative to endoscopic procedures. While there are currently rigid ingestible diagnostic capsules on the market, a team of researchers in the College of Engineering led by professor of materials science and engineering and biomedical engineering

professor of mechanical engineering to improve the strength, lifespan, and control of biohybrid actuators. Researchers from Northwestern University and The Georgia Institute of Technology will also contribute to the project, supported through a $6.25 million Multidisciplinary University Research Initiative (MURI) grant from the Department of Defense. Over the course of five years, the project aims to identify how to combine living materials, protein-based materials, and engineered materials to build larger scale, self-sustaining bio-actuators; understand how to keep these materials alive in a real-world environment, and determine how to leverage computational design strategies to improve peak performance. “Right now our bio-hybrid robots run around in petri dishes and in sterile incubators,” explained Webster-Wood. “Through this project we hope to leverage our understanding of living muscle to create stronger, more useful muscle-based actuators.”
With support from researchers across labs at the Department of Defense and the Department of Energy, the team intends to keep the idea “how do we move toward translation” at the center of the project to make sure that their work is constantly progressing toward real-world use. “We are excited to work with this cross disciplinary team to push the boundaries of soft robotics towards new applications, such as bio prosthetics,” said Feinberg. “Our lab will contribute our FRESH 3D bioprinting technology to build muscle tissue and soft materials together into integrated living machines with novel capabilities.” Additionally, Cohen-Karni’s lab will develop materials and tools to monitor the biohybrid robots’ health and state. Working closely with Rivnay group from Northwestern University, his research group will identify ways to sustain engineered tissues for a prolonged period through locally produced nutrients.

work with University of Sheffield’s School of Management in partnership with their department of materials science. Their research was a life cycle assessment of ceramic tile production in the United Kingdom, which involved breaking down the manufacturing process into its component steps and calculating the energy and CO2/water emissions at each step. “I now have a greater knowledge base in both ceramics and spreadsheet-based modeling/data manipulation,” said Hung. “This experience has shown me the different kinds of work that MSE majors have available to them post-graduation, and thus will help me focus my future courses and commitments.” Junior student Melinda Chen applied for the program because she wanted to gain experience doing hands-on laboratory work with electronic materials for an extended period of time, particularly as she decides whether to pursue a graduate degree. Her work on characterizing potential lead-free ceramic dielectric materials included synthesizing, processing, and running tests (e.g. X-ray diffraction, capacitance measurements, impedance spectroscopy, scanning slectron microscopy) to identify both the underlying structure of the material as well as its electrical properties.

sport, which can be confusing to participants as they try to determine which lines are meant for their activity. While some facilities are able to use LED lighting to remedy this issue, the costs associated with this option are prohibitive. An undergraduate materials science and engineering team advised by MSE Professor Vincent Sokalski used their capstone project as an opportunity to demonstrate a more affordable solution to making multisport courts less confusing, creating a model that showcases the feasibility of the idea. Senior students Alan Gallardo, Kacy Liang, Abby Ngowe, and Justin Ryu used a polymer-dispersed liquid crystal (PDLC) film, which is part of a special class of materials known as electrochromics whose optical properties can be changed by exposure to an electric field, to showcase this approach. PDLC films embedded into a stack of conductive polymer layers allow for its changing from transparent to opaque with the flip of a switch. Traditionally used in privacy glass, the team used this
The capstone class, a requirement for all undergraduates, affords the opportunity for students in their senior year to take what they have learned thus far and apply it to a hands-on learning project. “This project was the best practical application of classroom taught knowledge obtained from past courses,” said Liang. “For example, we utilized American Society for Testing and Materials (ASTM) standards to structure our material tests and conducted tensile testing on the Instron, a machine we used in a previous lab course.” Using a compression test apparatus, the group found that PDLC fails when pressure exceeds about 7000 psi - far more pressure than the court’s typical use would be exposed to. The team also examined the change in optical properties as the material was exposed to more force, as well as the impact on opacity when stacking layers of the material.

“THIS PROJECT WAS THE BEST PRACTICAL APPLICATION OF CLASSROOM TAUGHT KNOWLEDGE OBTAINED FROM PAST COURSES.” - KACY LIANG, MSE’23
Following these initial tests, the group members developed a two-court version prototype that had basketball court dimensions scaled to an NBA court, as well as a pickleball court. Using maple hardwood along with PDLC film lines connected to a battery, the model examined the differences between one and two layers of PDLC. “This experience taught me about the high-level planning that is required to bring a project from ideation to execution,” said Ngowe. “It helped me advance my skills in setting long-term and short-term deliverables that would resemble those encountered in a professional environment.” Lastly, the group conducted a feasibility study reviewing patent novelty, environmental impact, installation, maintenance and cost considerations. They proposed developing a mold for the line shapes and dimensions in order to contain costs and covering with polyurethane and wax to best maintain the lines over time. Participating in the capstone course effectively prepares students for their next step after completing their degree, whether it is in continuing their education or entering the workforce. “It is important for undergraduates to gain experience working with peers in a project setting to build effective and productive mindsets and habits that will prepare them for whatever professional endeavors they choose to take,” said Gallardo. This project will continue to be further developed as future capstone classes work with faculty to identify solutions that have potential for real world application.

MSE ALUMNA NAMED TO FORBES “30 UNDER 30” IN ENERGY
MEET THE 2023 MSE ALUMNI ADVISORY COUNCIL
Forbes recently named Olivia Dippo BME/MSE ’15 to its 30 Under 30 in Energy list for her innovative developments as CEO and co-founder of Limelight Steel. Dippo recalls how her undergraduate Introduction to Materials Science class combined “hands-on lab experience with the theory to understand how atomic-scale phenomena affected human-scale materials behavior.” After gaining an initial interest in steel and metallurgy from her professors and Pittsburgh’s rich history, she joined professor Tony Rollett’s lab. She credits him with being an encouraging mentor who inspired her to follow in his footsteps and secure a job at Los Alamos National Laboratory. Dippo and her co-founder and friend, Andy Zhao, discussed their initial ideas for Limelight Steel at weekly meetups over coffee. Together, their expertise in their respective fields allowed them to realize they had a solution for lowering CO2 emissions in the iron and steel industry by targeting the blast furnace that is currently used for steelmaking. The current method is responsible for 8-10% of global CO2

“Steel demand continues to grow as the world continues to industrialize, so it’s imperative that we decouple the steel that’s used for infrastructure, automobiles, and so many more applications in our daily lives, from CO2 emissions,” Dippo says. Limelight Steel’s laser furnace technology uses approximately 40% less
