X-ray crystallography at the heart of life science.
X-ray crystallography is the fundamental research tool that shaped our notion on biological structure & function at the molecular level. It generates the information vital to understand life processes by providing the information required for creating accurate three-dimensional models (namely mapping the position of each and every atom that makes up the studied object). The use of this method b...
متن کاملA Focus on Crystallography
The assignment of atom types is one of the first stepsafter solving a single crystal X-ray structure analysis. It isoften difficult or even impossible to assign correct atomtypes if there are atoms with similar atomic number pres-ent in the structure solution. The Cambridge StructuralDatabase (CSD) allows to perform statistical analysesof bond lengths and delivers an ele...
متن کاملCrystallography on a chip.
A new chip-based crystal-mounting approach for rapid room-temperature data collection from numerous crystals is described. This work was motivated by the recent development of X-ray free-electron lasers. These novel sources deliver very intense femtosecond X-ray pulses that promise to yield high-resolution diffraction data of nanocrystals before their destruction by radiation damage. Thus, the ...
متن کاملIntroduction to a general crystallography.
The definition of an extended crystallographic group is given, based on an n-dimensional Euclidean space, carrier of a faithful integral representation of a permutation group of atomic positions. The Euclidean crystallography of normal crystals and the higher-dimensional one applied to incommensurately modulated crystals, intergrowth crystals and quasicrystals are special cases of a general cry...
متن کاملCosmic crystallography in a circle
In a circle (an S 1) with circumference 1 assume m objects distributed pseudo-randomly. In the univeral covering manifold R 1 assume the objects replicated accordingly , and take an interval L > 1. In this interval, make the normalized his-togram of the pair separations which are not an integer. The theoretical (expected) such histogram is obtained in this report, as well as its difference to a...
