The Status of Clay Mineral Structures
THE basic outlines of most of the hydrous layer silicate structures were determined during the 1930's. Present escalating interest in obtaining additional detail is indicated by (a) publication of over twenty structural refinements (2-D or 3-D) during 1954-64, (b) publication of a t least nine structures in 1965 or early 1966, and (c) personal communicat ion tha t a t least fifteen additional r...
متن کاملGas Sorption in Clay Mineral Systems
-Sorption isotherms for four gases (N2, A, Kr and C O 2 ) , commonly used in specific surface area and pore structure measurements, have been accurately determined on a number of clay mineral and oxide systems. Specific surface areas obtained by application of the BET theory to these isotherms illustrate the extent to which the apparent cross-sectional areas for these sorbed gases vary with sur...
متن کاملMineral Acquisition from Clay by Budongo Forest Chimpanzees
Chimpanzees of the Sonso community, Budongo Forest, Uganda were observed eating clay and drinking clay-water from waterholes. We show that clay, clay-rich water, and clay obtained with leaf sponges, provide a range of minerals in different concentrations. The presence of aluminium in the clay consumed indicates that it takes the form of kaolinite. We discuss the contribution of clay geophagy to...
متن کاملPolyolefin-Clay Nanocomposites from Olefin Polymerization between Clay Layers
This mini-review article addresses the development in synthesizing polyolefin/clay nanocomposites by olefin polymerization under catalysis of clay intercalated precatalysts in recent years. The review comprises three parts which focus on mainly the synthetic route, structural characterization, and properties of polyolefin/clay nanocomposites, respectively. Moreover, outlook for future research ...
