Undergraduate researcher Megan Gillespie taught local high school students during the week-long Materials Science and Engineering annual Materials Science Camp! Megan’s role involved preparing materials for slip casting and sand-casting demonstrations, teaching the students about poster design, and mentoring. The high school students also toured the Scintillation Materials Research Center, with graduate students Bethany Claes, Kaden Anderson, and Chris Fritz as tour guides.

Last week, PhD students Sarah Longworth and Rebecca Lalk drove out to Texas A&M University to attend the NNSA’s Office of Defense Nuclear Nonproliferation Research and Development University Program Review (UPR), 2024.

Sarah Longworth, a fellow of the Nuclear Science and Security Consortium (NSSC), presented a poster titled “Investigating Gd2Al2O7 as a Scintillator Candidate.” What Sarah enjoyed most about UPR was connecting with researchers who use scintillators for their own work and learning more about how her research fits into the diverse field of nuclear security.

Rebecca Lalk, an affiliate of the NSSC, presented a poster titled “Thermoluminescence Investigation of High Entropy GYTLAG Garnet Scintillator.” Rebecca says that what she most enjoyed about UPR was hearing about all of the other students’ research and realizing what a large number of fields are research areas make important contributions to the nonproliferation mission.

They would like to extend their gratitude to Texas A&M for hosting, to the NNSA for funding the university consortia, and to the conference organizer. Also, thanks especially to the NNSC for providing many opportunities to connect with the nonproliferation mission and to their advisors who support them in such interesting work.

Last week, PhD student Rebecca Lalk traveled to Daytona Beach, FL, to deliver a talk titled "Scintillation Mechanism in a GYTLAG Single Crystal" at the 48th International Conference & Exposition on Advanced Ceramics & Composites (ICACC).

This trip was made possible thanks to a travel award from the Center for Materials Processing (https://cmp.utk.edu/) at UT as well as a student registration fee waiver granted by the conference organizers.

In addition to attending exhilarating talks and enjoying the beach, Rebecca met a few SMRC alumni, including previous undergraduate researcher Madeline Loveday and previous graduate student Dr. Josh Smith. Rebecca says that this conference was a great experience. She's also thankful to her coauthors and other SMRC coworkers who supported her.
