Understanding the structural properties of a dendrimeric material directly from powder X-ray diffraction data
Article Abstract:
The complete determination of an early-generation dendrimeric material was carried out directly from powder X-ray diffraction data using the direct space genetic algorithm technique for structure solution followed by Rietveld refinement. The success of this new technique paves the way for the future application of this approach to enable complete structure determination of other dendritic materials that cannot be prepared as single crystal samples suitable for single crystal X-ray diffraction studies.

Gracing incidence X-ray diffraction on Langmuir films: Toward atomic resolution
Article Abstract:
The grazing incidence diffraction (GIXD) data from condensed phases of Langmuir films of long-chain fatty acids at the air-water interface was analyzed using a method consisting of a careful extraction of the structure factors followed by fitting of molecular parameters. It is shown that, contrary to the general belief, the information contained in GIXD spectra is enough to obtain near-atomic structural information.
