One of Earth's most abundant minerals, calcite is a major component of limestone and marble. It is also the most stable of ...

Here we use Bragg coherent diffraction imaging to investigate a contrasting system, the epitaxial growth of calcite (CaCO 3) crystals on organic self-assembled monolayers, where these are widely ...

The fossilized, spherical eggs belong to a previously unknown dinosaur species and were found packed with calcite crystals. They were unearthed in the Qianshan Basin in East China's Anhui province.

Hilton, with Dr. Harry Berman, a mineralogist from Harvard, had discovered the “optical” calcite, a common crystal deposited in veins in the desert’s sandstone. This high-grade calcite ...

These animals sometimes grow tinier calcite crystals in their eyes or in their rigid exoskeletons for strength, but not “one big crystal basically in each individual lens,” he says.

The work in Nature Communications, external can hide centimetre-sized objects, limited only by the calcite crystal's size. The approach offers a simpler, more scalable route to invisibility than ...

Cordierite and Tourmaline crystals were tested. So was crystallised calcium carbonate, otherwise known as Iceland spar. This is the same stone as found in the Elizabethan wreck. Calcite was found ...
