متن کاملConference Report: ACCURACY IN POWDER DIFFRACTION II: A REPORT ON THE SECOND INTERNATIONAL CONFERENCE Gaithersburg, MD May 26–29, 1992
The purpose of this conference was to assess the progress that has been made in the theory, techniques, and applications of powder diffraction data since the first highly successful symposium on Accuracy in Powder Diffraction held at NIST (then the National Bureau of Standards) in 1979, as well as to define problem areas where further work is needed. The proceedings of the first symposium, publ...
متن کاملAtomic pair distribution function analysis from the ARCS chopper spectrometer at the Spallation Neutron Source
Neutron powder diffraction based atomic pair distribution functions (PDFs) are reported from the new wide angular-range chopper spectrometer ARCS at the Spallation Neutron Source (SNS) at Oak Ridge National Laboratory (ORNL). The spectrometer was run in white-beam mode with no Fermi chopper. The PDF patterns of Ni and Al2O3 were refined using the PDFfit method and the results compared to data c...

متن کاملPowder crystallography on macromolecules.
Following the seminal work of Von Dreele, powder X-ray diffraction studies on proteins are being established as a valuable complementary technique to single-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 ...
