Ultrafast Powder Diffractione resolution of 500 ms or less. The experimental requirements to obtain data of good quality are considered, including the incident flux, detector characteristics, and the different strategies possible for irreversible and reversible processes. The latter are accessible via a stroboscopic approach w

Proteins and Powders: Technical Developments and the large unit cells lead to severe peak overlaps, creating interesting challenges. Powder diffraction remains as the unique tool to characterize certain polymorphic forms of crystalline proteins.

Proteins and Powders: An Overviewsingle crystal measurements. A wide range of small proteins have been found to give synchrotron powder diffraction profiles where the peak widths are essentially limited only by the instrumental resolution. The rich information contained in these profiles, combined with developments in data analysis

Powder Diffraction+Computational Methodst typical for single crystal standards. Although theoretical calculations and powder diffraction seemingly represent completely disjunctive sets, it is demonstrated that they could meet at three stages of structure analysis from powders – initial model building, structure refinement and crystal chem

A fast analysis is always possible via traditional techniques such as the Scherrer formula, Williamson-Hall plot and Warren-Averbach method, but at the expenses of the physical meaning of the result. A more sound alternative is offered by the Whole Powder Pattern Mode
