Materials Synthesis

The Radiological Materials and Technology Development group has accumulated experience in synthesis of a large variety of glass, ceramic, and metallic materials. Our core expertise lies in the materials we produce in the oxide Glass Development Laboratory (GDL) and the Non-Oxide Material Synthesis Laboratory (NOMSL). Additionally, we work closely with other groups who steward specific capabilities, such as different specialized thin film deposition methods, for example. Our scientists have been involved with a large number of projects involving specialized materials including recent work in:
