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 کاملMolecular order and disorder of surfactants in clay nanocomposites.
Disorder of intercalated surfactant molecules in clay minerals causes gradual swelling, rather than commonly assumed swelling in discrete steps.
متن کاملMolecular order and disorder of surfactants in clay nanocompositeswz
Nanocomposites of clay minerals and surfactants are of practical importance in many fields. Beside the use of these systems for pollution removal from waste water, they can also be used as catalysts, to stabilize clay formations while drilling for hydrocarbons, or for improving the strength of polymers. The nanocomposites are obtained through exchange of natural counter ions by ionic surfactant...
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 کاملneuropsychological structures in postpartum blues disorder
Introduction: The association between depression and brain systems has received both theoretical and empirical support. However, less is known about the behavioral brain systems and postpartum blues in this relationship. This research investigates the role of neuropsychological structures in postpartum blue: According revised reinforcement sensitivity theory. Methods: The present study was a de...
