The Geophysical Laboratory's weekly seminar series continues with Peter C Burns of  University of Notre Dame. 

Dr. Burns is Director of the Energy Frontier Research Center Materials Science of Actinides. This EFRC, which is funded by the Department of Energy, includes senior researchers and students at six universities and three national laboratories.  The Center research emphasizes basic research in actinide chemistry and materials science to help create the foundation of knowledge needed for an advanced nuclear energy system of the future.  The Center emphasizes complex actinide materials, the control of actinides at the nano-scale, and actinide materials under extreme environments of pressure, temperature, and radiation field.

Dr. Burns’s research focuses on the solid state and environmental chemistry of heavy metals, especially actinides including uranium, neptunium and plutonium. Studies of natural crystals coupled with synthetic approaches are being used to develop the structural hierarchical relationships in actinide compounds. Aggregation of metals in solution, and subsequent crystallization of molecular clusters, is examined using conventional crystallographic techniques coupled with synchrotron X-ray scattering. Current emphasis includes studies of the structures and stabilities of uranium, thorium and plutonium clusters containing as many as 120 metal atoms. Much of this research is applied to nuclear waste disposal and understanding the mobility of actinides and heavy metals in the environment. The structures, compositions, stabilities, and thermochemistry of uranium compounds is studied in relation to the evolution of a geological repository for nuclear waste, as well as natural uranium deposits.

The Geophysical Laboratory's weekly seminar series continues with Peter C Burns of  University of Notre Dame. He will present, "Electron backscatter diffraction in materials and planetary sciences: From welds to iron meteorites."

Coffee, tea, and a light breakfast will be served before the lecture, at 10:30 a.m.
