and a search through the literature reveals that there is almost no information on the formula and crystal structure of cobalt molybdate. A mineral paterite is known which is quoted as having the ...

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 ...

Hexagonal close packing is one of two crystal structures that derive from stacking close-packed-planes of hard sphere atoms. In the HCP structure only two stacking ...

More than 4,000 naturally occurring minerals—inorganic solids that have a characteristic chemical composition and specific crystal structure—have been found on Earth. They are formed of simple ...

With each chapter there is an accompanying quiz (click on the chapter title in the further resources directory) to measure your learning. How many of these questions can you answer without looking at ...

It has been announced that following Bristol-Myers Squibb’s (BMS) successful acquisition of Amylin Pharmaceuticals, AstraZeneca (AZ) has made an initial payment of approximately US $3.2 billion ...

Researchers developed a bifocal lens based on two layers of liquid crystal (LC) structures. The intensities for the two focal lengths can be easily adjusted by applying external voltage.

The lenses, which use two layers of liquid crystal structures, could be useful for various applications such as optical interconnections, biological imaging, augmented/virtual reality devices and ...

This approach can be used to generate new materials that have radically different crystal structures and physical properties, even though their chemical composition is the same, according to the ...
