DTRA’s advancements in nuclear and radiological detection
A new, more complex nuclear age has begun. Echoing the tensions of the Cold War amid rapidly evolving nuclear and radiological threats, preparedness in the modern age is a contest of scientific innovation. The Research and Development Directorate (RD) at the Defense Threat Reduction Agency (DTRA) is charged with winning this contest.

The work function change of Li4SiO4 and Li2TiO3 were measured in atmosphere of various gas compositions with a high temperature Kelvin probe. The work function change of Li4SiO4 was found to be composed of two steps: one was caused by the formation of oxygen vacancies and the other corresponding to the population change of OH− at the surface. While, a single step of the work function change was observed for Li2TiO3. That was attributed to the adsorption/desorption processes at the surface. It was suggested that oxygen vacancies are formed in near-surface bulk of Li4SiO4, it is not in the case for Li2TiO3.
