Electron Powder Diffraction - An old topic rediscovered for structure determination of nanocrystalline materials

Structure determination from powder diffraction data.

Advances made over the past decade in structure determination from powder diffraction data are reviewed with particular emphasis on algorithmic developments and the successes and limitations of the technique. While global optimization methods have been successful in the solution of molecular crystal structures, new methods are required to make the solution of inorganic crystal structures more r...

VII. Workshop Powder Diffraction Structure Determination and Refinement from Powder Diffraction Data

New techniques have been integrated into EXPO (Altomare et al., 1999), a package devoted to extracting the integrated intensities from an indexed powder diffraction pattern and to solving crystal structures via Direct Methods. An efficient peak-search algorithm and an improved version of the program TREOR90 (Werner et al., 1985) have been introduced in order to offer new tools for a more powerf...
