Seljakow, J. Kurdumoff, and N. Goodtzow (NATURE, 119, 494; 1927), that quenched carbon steels contain a phase with a tetragonal crystal structure, which might be considered as a deformation of the ...

More than 4,000 naturally occurring minerals—inorganic solids that have a characteristic chemical composition and specific crystal structure ... or individual elements arranged in repeating ...

We describe here the crystal structure of BoNT/A and then use this structural information to address some of these mechanistic questions. The binding domain, with overall dimensions of 32 Å × 37 ...

This approach can be used to generate new materials that have radically different crystal structures and physical ... each contain bismuth and one other element, could be useful in the design ...

Emeralds are mainly made up of the mineral beryl, which is made from the elements beryllium, aluminum, silicon and oxygen. Beryl’s crystal structure is more complicated than corundum’s because ...
