Analysis of Defects in Physical Vapor Transport Grown 4H-SiC Substrates and Chemical Vapor Deposition Grown Homo-Epitaxial Layers Using Synchrotron X-ray Topography
Synchrotron White Beam X-ray Topography studies are presented of dislocation behavior and interactions in 4H-SiC wafers grown using Physical Vapor Transport under specially designed low stress conditions. Such low stress growth conditions have enabled reductions of dislocation density by two or three orders of magnitude compared to the lowest previously reported levels.
Engines, Fuels, and Aftertreatment

Groundbreaking engine research that advances the use of conventional and alternative fuels and the design of advanced technology vehicles

Energy Systems Analysis

Consumer behavior, economic conditions and market forces interact on many levels to influence the acceptance of new technologies and their potential impacts on energy efficiency and the environment. The Argonne National Laboratory analysis team includes a diverse group of engineers, technology analysts, economists, policy analysts and planners who work with the U.S. Department of Energy and other sponsors to assess programs and develop tools for the public to use in calculating potential energy, resource and emissions savings from implementation of new fuels and technologies.

Why Fast Reactors? And When?
The talk will be a survey of how fast reactors can address the disadvantages of current light water reactors (at least per conventional wisdom). The fundamental differences in reactor physics, reactors safety, and fuel cycle options between LWRs and sodium-cooled fast reactors will be reviewed, as will the potential markets for SFRs.
