A small team led by Sihao Cheng, Martin A. and Helen Chooljian Member in the Institute for Advanced Study's School of Natural ...

The Milpo mine is known to produce fluorite crystals with inclusions of various sulfides. Since the fluorite and geocronite are intimately intergrown, the opaque silvery gray bodycolor of the ...

There is another interesting consequence associated with the presence of screw dislocations during crystal growth. Crystal growth is associated with a coaxial screw dislocation inside a finite ...

The surface morphological studies from Scanning Electron Microscope (SEM) and HRTEM depicted spherical particles with formation of clusters. Thermal and electrical ... and HRTEM images is 20 nm with ...

and disordered (fluorite) phases. Another approach, which can also be used to examine alternative cation arrangements and their temperature dependence via Monte Carlo, is cluster expansion (CE). Below ...

Among the works of art from nature — the show includes several quartz specimens mined in Arkansas — was a spectacular piece: a 5-foot-6-inch cluster of limpid crystals emerging from a quartz ...
