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 ...

A phase transition from the fcc to a hexagonal close-packed (hcp) structure was found in NiCoCrFe starting at 13.5 GPa and the hcp structure is quenchable to ambient pressure. Only a very small amount ...

This interaction produces a diffraction pattern that is characteristic of the sample's structure. The principle of operation for XRD involves the Bragg's Law, which relates the wavelength of the ...
