March 02, 2020: Physics faculty and students participate in the 2020 Stewardship Science Academic Programs Symposium
Freimann Professor Ani Aprahamian, Research Assistant Professor Khachatur Manukyan, and graduate students Stefania Dede, Ashabari Majumdar, Jordan Roach, and Jacob Galden participated in U.S. Department of Energy’s National Nuclear Security Administration (NNSA) 2020 Stewardship Science Academic Programs (SSAP) Symposium held February 26-27, 2020 in Washington, D.C. Aprahamian presented the progress of last year’s research activities of the “A Novel Technique for the Production of Robust Actinide Targets” grant funded by NNSA. Students presented their research results as poster presentations. This project brings together expertise from material science, radiochemistry, and nuclear science. The aim of the project is to develop new ways to prepare thin actinide targets for research in nuclear science and stockpile stewardship. This grant provides exciting opportunities for carrying out cutting-edge research while educating the next generation of STEM scientists capable of exploiting the developed techniques. This project expands the scope with novel techniques and the training of new personnel that can satisfy national needs at both Los Alamos and Lawrence Livermore National Laboratories. The project is also featured in the 2020 Stewardship Science Academic Programs Annual Report Journal (DOE/NE-0109).

August 28, 2019: Nuclear Science Laboratory researchers publish an article on the surface manipulation techniques of Roman denarii
A team of researchers and undergraduate students at Nuclear Science Laboratory, Department of Physics at Notre Dame, published an article in the Applied Surface Science journal on the characterization of a set of Roman denarii, ranging from 136 BCE to 240 CE. The work presents the results of macro, micro, and nanoscale surface characterization of coins using several different X-ray based spectroscopic and electron microscopy methods. This enabled the surface, the subsurface, and volume composition of these coins to be probed to better understand their production techniques, surface treatment methods, and corrosion patterns. The results also provide evidence that a particular surface treatment method, amalgam silvering, had been used to make authentic Roman coins as early as the third century CE.

April 18, 2019: Laura Richter was awarded the 2019 Radwan and Allan Riley Prize in Art History for her research paper within Medieval Art History. Additionally, she has received a summer research grant through Notre Dame’s Institute for Scholarship in the Liberal Arts (ISLA) to carry out a photogrammetry project at Mesa Verde National Park this August. She will be working to create 3-dimensional digital models of the celebrated Puebloan cliff dwellings across the site.
