Work done in the Department of Physics and Astronomy was presented at the 2012 European Materials Research Society meeting in Strasbourg, France. Physics students Pragalv Karki, Ravindra Regmi, Tom Mooney, and Andrew Larson worked with Dr. Ananda Shastri to analyze proton motion in the sodium thio-hydroxogermanate proton conductors. Understanding these materials may lead to better fuel cell performance. The results have been accepted for publication in the international journal Solid State Ionics.
