For many decades, the method to obtain atomic-level descriptions of chemical compounds and materials—be it a drug, a catalyst ...

X-ray crystallography is a technique that uses X-ray diffraction patterns to determine high-resolution, three-dimensional structures of molecules such as proteins, small organic molecules, and ...

POSSIBILITIES for X-ray crystal structure analysis of proteins are limited by the minimum spacings observed in diffraction. For many proteins, the minimum spacing is about 2.5 A.—a limit which does ...

A story of the impressive Chandra X-ray Observatory, how the telescope works, and the sad recent news of budget cuts halting ...
