When looking at calcite under a microscope, a scientist would immediately recognize the crystalline form of calcium carbonate by its rhombohedral appearance. That is, calcite is shaped like a ...

Spots of light glinted off the faceted sides of more than a dozen calcite crystals stuck inside a small cave at the top of a steep, rocky couloir. Tom Benedict balanced on a thin log spread across the ...

Ling Li, an assistant professor in mechanical engineering at Virginia Tech, has found insights into building stronger and tougher ceramics by studying the shells of bivalve mollusks. EPFL's Laboratory ...

Explore Florida’s rich fossil beds to find ancient clams hiding beautiful calcite crystal formations inside. This ...

Professor Snape beware -- invisibility cloaks aren’t just for the microscopic anymore. Using natural crystals, two independent research teams have designed “carpet cloaks” that can abracadabra 3-D ...

Inclusion of organic molecules in inorganic crystals is thought to enhance their mechanical properties, yet obtaining high occlusion levels has been a challenge. It is now shown that synthetic calcite ...

Researchers reveal an invisibility cloak made from calcite crystals, paving the way for visual cloaking of larger objects. "By using natural crystals for the first time, rather than artificial ...

This is a preview. Log in through your library . Abstract The interplay between polymorphism and facet-specific surface energy on the dissolution of crystals is examined in this work. It is shown that ...

A collection of crystals found at the archaeological site Ga-Mohana in the Kalahari Desert. The name Kalahari is derived from the Tswana word Kgala, meaning 'great thirst'. And today the climate at Ga ...

When the Vikings left the familiar fjords of Norway for icy, uncharted territories, they were at the mercy of weather. They had no magnetic compasses, and no way to ward off stretches of heavy clouds ...
