Crystal structures of iron-nitrogen compounds. Orange and blue balls show the positions of Fe and N atoms, respectively. a Fe3N2 at 50?GPa. The structure is built of quadrilateral face-capped trigonal ...

AT the recent meeting of the Iron and Steel Institute Messrs. A. Westgren and G. Phragmen presented a continuation of work published by them two years ago at the same Institute. The present paper ...

Researchers have devised a mathematical approach to predict the structures of crystals -- a critical step in developing many medicines and electronic devices -- in a matter of hours using only a ...

The erudite science of solid-state physics can predict from theory how strong a metallic crystal should be if all its atoms were arranged in a perfect, regular pattern. The figure is usually so high ...

Every crystal's shape is a mirror of the internal arrangement of its molecules, but the molecules in photoswitchable crystals can expand, twist and change properties—from their color to their ...
