Electron powder diffraction [PDF]

, 2007
Electron powder diffraction patterns can be recorded from small volumes of nanoparticles or localized areas of nanocrystalline thin films, which makes electron diffraction a complementary technique to X-ray and neutron powder diffraction for challenging samples.

The Path of an Industrial Powder Small-Molecule Crystallographer [PDF]

Structural Dynamics
In this historical talk, I will begin with some of the early history of powder diffraction in the US and my relation to it. My industrial and (fairly- convoluted) external career intersected with a number of significant developments in hardware, software,

Identifying and Indexing Icosahedral Quasicrystals from Powder Diffraction Patterns

, 2001
We present a scheme to identify quasicrystals based on powder diffraction data and to provide a standardized indexing. We apply our scheme to a large catalog of powder diffraction patterns, including natural minerals, to look for new quasicrystals. Based
