Clay minerals and sedimentary basin history [PDF]
, 2005 Clay minerals in the mud and soil that coat the Earth's surface are part of a clay cycle that breaks down and creates rock in the crust. Clays generated by surface weathering and shallow diagenetic processes are transformed into mature clay mineral ...

Correlation between chemical and mineralogical characteristics and permeability of phyllite clays using multivariate statistical analysis [PDF]
, 2016 Phyllite clays are applied as a layer on a surface to be waterproofed and subsequently compacted. For this purpose, phyllite clays deposits can be grouped by their chemical and mineralogical characteristics, and these characteristics can be connected ...

Polyethylene and Polypropylene Nanocomposites Based on Polymerically - Modified Clay Containing Alkylstyrene Units [PDF]
, 2006 Sodium montmorillonite was modified with a new polymeric surfactant. The high molecular weight of the surfactant appears to have led to incomplete cation exchange of the clays, but did promote nanocomposite formation with polyethylene and polypropylene ...

Polystyrene Nanocomposites based on Carbazole-Containing Surfactants [PDF]
, 2005 New organically-modified clays containing a carbazole unit were prepared and the number of long alkyl chains on the surfactant was varied. The clay was used to prepare polystyrene nanocomposites by both bulk polymerization and melt blending.
