Interstitial Fractionalization and Spherical Crystallography [PDF]
Finding the ground states of identical particles packed on spheres has relevance for stabilizing emulsions and a venerable history in the literature of theoretical physics and mathematics.

PRODRG: a tool for high-throughput crystallography of protein-ligand complexes.
The small-molecule topology generator PRODRG is described, which takes input from existing coordinates or various two-dimensional formats and automatically generates coordinates and molecular topologies suitable for X-ray refinement of protein-ligand ...

Virus crystallography can provide atomic resolution structures for intact isometric virus particles and components thereof. The methodology is illustrated by reference to a particularly complex example, the core of the bluetongue virus (700 A).

Quantum crystallographic charge density of urea [PDF]
Standard X-ray crystallography methods use free-atom models to calculate mean unit cell charge densities. Real molecules, however, have shared charge that is not captured accurately using free-atom models.

We summarize exploratory work on multigrain crystallography. The experimental arrangement comprises a monochromatic beam, a fully illuminated sample with up to several hundred grains in transmission geometry on a rotary table and a 2D detector. Novel algorithms are presented for indexing, integration and filtering with emphasis on handling the ...

An integrated web resource for crystallography
A recurring theme during the CODATA 2000 conference (Lake Maggiore, Italy, 15 - 19 October 2000) was the increasing convergence in data-rich branches of science between the storage and retrieval of data and the publication of conclusions drawn from the ...

Characterization of crystal structure and precipitation crystallography of a new MgxAl2-xGd phase in Mg97Al1Gd2 alloy [PDF]
The composition, crystal structure and precipitation crystallography of a newly found precipitate are characterized by a Cs-corrected scanning transmission electron microscopy (STEM). The composition of the plate-like precipitate could be expressed as MgxAl2-xGd (x = 0.38), and its crystal structure is the same as the fcc type Laves phases Mg2Gd and ...
