FROM an examination of the available data for cellulose and the sugars, we have formed the conclusion that the six-atom sugar ring is associated in the crystalline state with certain linear ...

The crystal has a lattice parameter of 0.541 nm. The crystal structure is also known as diamond cubic and may be thought of as two interpenetrating fcc lattices, one for sulphur the other for zinc, ...

Sodium Chloride is an alkali halide with an fcc crystal structure. The basis is two ions, a sodium cation and a chlorine anion. The crystal lattice parameter is 0.563 nm. The diagram shows both a unit ...

While the phenomenon has been seen in materials where electrons are constrained to just two dimensions, this is the first ...
