Publication number: 20130052116Abstract: Inclusion of a needle structured clay or the plate structured clay sodium montmorillonite in a chitosan film was found to reduce shrinkage of the film. The needle structured clay is purified and processed into a substantially dispersed form by subjecting an aqueous slurry of the clay with water-soluble phosphate dispersant to a high pressure, high shear mixing process or to sonication. Laminates fabricated from chitosan film including dispersed clay can be used in make a variety of finished articles that can be used to provide protection from hazardous chemical and biological agents.Type: ApplicationFiled: September 14, 2012Publication date: February 28, 2013Inventors: Nathaniel A.

Patent number: 8202501Abstract: The invention relates to a method for preparing a synthetic talc composition. According to said method, a kerolite composition is subjected to an anhydrous thermal treatment carried out at a pressure lower than 5 bar, from over a few hours up to over a few days, at a treatment temperature higher than 300° C. The invention also relates to a synthetic talc composition prepared in this way, the synthetic talc particles of the composition being exclusively of chemical formula —(Si4)Mg3O10(OH)2— and identifiable, during X-ray diffraction, by the presence of a characteristic diffraction peak located at a distance of between 9.40-9.68 and corresponding to a plane (001). Said synthetic talc particles also have a thermally stable crystalline structure of stacked laminae, which is very similar to that of a natural talc and has a particle size smaller than approximately ten micrometers.Type: GrantFiled: July 13, 2007Date of Patent: June 19, 2012Assignees: Luzenac Europe SAS, Centre National de la Recherche Scientifique (C.N.R.S.)Inventors: Francois Martin, Jocelyne Ferret, Cedric Lebre, Sabine Petit, Olivier Grauby, Jean-Pierre Bonino, Didier Arseguel, Alain Decarreau, Eric Ferrage

Publication number: 20120131973Abstract: A filter for treating CO2 from a CO2-emitting industrial plant, takes advantage of the fact that peridotite igneous rocks (or material of similar chemical content: basalt, gabbro, dunite, amphibolites, artificially produced Ca, Mg oxides) which are abundant on and close to the Earth's surface, can absorb and contain CO2 gases resultant from industrial activity. This chemical process occurs naturally, but has not been utilized to capture high concentrations of CO2 emitted into the atmosphere. Calcium and magnesium oxides of the peridotite react with CO2 to form stable carbonate minerals. The invention enhances and expedites this natural process for the remediation of industrial pollutants such as CO2 from the oil, gas, coal, cement/concrete and like CO2-emitting industries, and provides a resource for materials in construction (concrete), steel, aviation and agricultural and other industries.Type: ApplicationFiled: November 28, 2011Publication date: May 31, 2012Inventors: Darius Greenidge, Jean Greenidge
