ROCK crystal, quartz, the common crystallised form of dioxide of silicon SiO2, is, from many points of view, the most interesting of all minerals and the most instructive example of crystalline ...

The ability to predict crystal ... structure of a crystalline material can be predicted with energy guarantees by an algorithm “that finds all the unknown atomic positions within a unit cell ...

In these materials, defects in the crystal ... with unit cells arranged either in perfect order, as in conventional metamaterials, or in motley groups of different atomic structures.

the Advanced Photon Source (APS), a DOE Office of Science User Facility -- they could determine the precise position of every atom in the crystal structure for different states of cell charge and ...
