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 ...

Experiments have yielded a fascinating new type of matter, neither granular nor crystalline, that responds to some stresses as a fluid would and to others like a solid. The new material, known as PAM ...

The matter’s ability to respond to environmental stimuli like electrical charges could revolutionize biomedical engineering ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies ...

Zinc sulphide exists with two different crystal structures, the cubic zinc blend (top diagram) and the hexagonal Wurtzite (lower diagram). In the zinc blend structure the sulphur ions form an fcc ...

In other words, they require knowledge about the crystal prior to determining its structure. This makes existing experimental data difficult to analyze when the lattice constant is not precisely ...
