A water-induced self-healing polymer hybrid was prepared by the hybridization of poly(vinyl alcohol) with smectite clay in aqueous media and subsequent casting.

ABS~CT Particle-size analyses of brickearth and Clay-with-flints from Kent, England, are presented. A calcareous sample of brickearth is comparable to loess. In th~ clay fraction, there is more illite (or glauconite) than kaolin; and there is some chlorite. The clay fraction of the Clay-withflints consists of smectite, illite and quartz and is probably derived directly from the Chalk. Black san...

introduction: minerals are one of the main components of soils which play different roles in the soils. minerals make up about 50% of the volume of most soils. they provide physical support for plants, and create the water- and air-filled pores that make plant growth possible. mineral weathering releases plant nutrients which are retained by other minerals through adsorption, cation exchange, a...

Identification of clay minerals based on chemometric analysis of measured infrared (IR) spectra was suggested. IR spectra were collected using the diffuse reflection technique. Discriminant analysis and principal component analysis were used as chemometric methods. Four statistical models were created for separation and identification of clay minerals. More than 50 samples of various clay miner...
