Sepiolite is a clay mineral found throughout in high quantities in New England, Arizona, and California. Its chemical makeup Mg4Si6O15 (OH)2·6H2O contains a hydrous magnesium silicate, causing a ...

Geologic clay deposits are mostly composed of phyllosilicate minerals containing variable amounts of water trapped in the mineral structure.

Acid and salt treatments lead to modification of the catalytic properties of clays. Clay mineral–polymer nanocomposites are the hybrids which exhibit a change in composition and structure on a scale ...

PHOTO CAPTION: Cliff Johnston uses a laser to look at a clay particle in his Purdue University lab. The laser helps Johnston study the structure and orientation of the clay. This particular layer is ...

A new ovoid structure discovered in the Nakhla Martian meteorite is made of nanocrystalline iron-rich clay, contains a variety of minerals, and shows evidence of undergoing a past shock event from ...

Researchers at the universities of Amsterdam and Utrecht have observed the formation of nanocavities in montmorillonite clay under exposure to gamma-aminobutyric acid, a molecule commonly found on ...
