This arrangement results in those familiar faceted faces we admire in quartz clusters and amethyst points. The repeating pattern is called a crystal lattice and gives the material its ...

Right: OH-defects in young (0.3 Gyr) Variscan granites are one order of magnitude higher than in old (0.9-1.8 Gyr) Proterozoic granites from Scandinavia . The OH-content is reflected in recent ...

More than one of our readers suggested we highlight this beautifully-shot process documentary about the laborious and precise manufacturing of piezoelectric quartz crystals in the early 1940s.

One of the tricks that researchers have used for a while now consists in reducing the motional energy of the electrons by artificially creating a crystal lattice with a large lattice constant ...
