Actinide Research Laboratory

Peter C. Burns

Description

Our research emphasizes the mineralogy and solid state chemistry of actinides, with applications in energy and environmental management.  Uranyl peroxide nanoclusters with well-defined structures are synthesized and characterized by the Burns group. The syntheses of several nano-scale cage clusters have been optimized and the characterizations of these materials are underway. Uranyl peroxide nanoclusters will be examined to determine their interactions with solutions and their own energetics.  The Burns group is exploring other uranyl materials that may contain cation-cation interactions through the synthesis of uranyl germanates, sulfates, selenates, tungstates, and arsenates.   We are also looking at the incorporation of neptunium into rock-forming minerals such as calcite and gypsum.
