A novel approach for finding and evaluating structural models of small metallic nanoparticles is presented. Rather than fitting a single model with many degrees of freedom, libraries of clusters from multiple structural motifs are built algorithmically and individually refined against experimental pair distribution functions. Each cluster fit is highly constrained. The approach, called cluster-mining, returns all candidate structure models that are consistent with the data as measured by a goodness of fit. It is highly automated, easy to use, and yields models that are more physically realistic and result in better agreement to the data than models based on cubic close-packed crystallographic cores, often reported in the literature for metallic nanoparticles.

A crystallographic indexing algorithm, pinkIndexer, is presented for the analysis of snapshot diffraction patterns. It can be used in a variety of contexts including measurements made with a monochromatic radiation source, a polychromatic source or with radiation of very short wavelength. As such, the algorithm is particularly suited to automated data processing for two emerging measurement techniques for macromolecular structure determination: serial pink-beam X-ray crystallography and serial electron crystallography, which until now lacked reliable programs for analyzing many individual diffraction patterns from crystals of uncorrelated orientation. The algorithm requires approximate knowledge of the unit-cell parameters of the crystal, but not the wavelengths associated with each Bragg spot. The use of pinkIndexer is demonstrated by obtaining 1005 lattices from a published pink-beam serial crystallography data set that had previously yielded 140 indexed lattices. Additionally, in tests on experimental serial crystallography diffraction data recorded with quasi-monochromatic X-rays and with electrons the algorithm indexed more patterns than other programs tested.

Chip Clark came to the Smithsonian's National Museum of Natural History in 1973, with a degree in biology and an interest in photography. He has been a photographer on staff ever since, documenting thousands of specimens and exhibits, and accompanying scientists on research trips around the world. He died June 12, 2010. This video interview was made by Lauren Dare, an intern with the Smithsonian Institution Archives, on May 27, 2010, as part of an oral history project for the National Museum of Natural History's Centennial (2010-2011). To learn more about Chip Clark, see his page on the Centennial website-- www.mnh.si.edu/onehundredyears/profiles/Chip_Clark.html -- where you also can find more videos and stories about the people and the work of the NMNH.
