We investigate the adsorption strength of some very toxic substances like lead, cadmium and mercury and sodium triphosphate, a highly environmental contaminant, on purified and homogenized fluorinated sodium montmorillonite NaFMt or “Rassoul”, and the influence on its electronic and surface-energy properties. The changes in the wettability of this clay due to the adsorbed elements are discussed in...
The catalytic activity in CH 4 oxidation over a La 0.8 Ce 0.2 MnO 3 perovskite as a model reaction is investigated under dielectric and conventional heating conditions. As these materials are both microwave sensitive and catalytically active, they may be applied as coating material for ceramic soot filters for the reduction of soot emission from diesel engines. Dielectric...
Abstract: We investigate the rheological properties of a cubic fcc phase of micelles obtained by aggregation of a triblock copolymer (PEO)127(PPO)48(PEO)127 in water as selective solvent. The resulting soft solid is submitted to a range of stresses varying from 20 to 800Pa in Couette geometry. Creep and flow behaviour can be distinguished and interpreted in terms of structural changes previously observed...
