Publication number: 20030160209Abstract: Formation of solid-water detoxifying reagents for chemical and biological agents. Solutions of detoxifying reagent for chemical and biological agents are coated using small quantities of hydrophobic nanoparticles by vigorous agitation or by aerosolization of the solution in the presence of the hydrophobic nanoparticles to form a solid powder. For example, when hydrophobic fumed silica particles are shaken in the presence of IN oxone solution in approximately a 95:5-weight ratio, a dry powder results. The hydrophobic silica forms a porous coating of insoluble fine particles around the solution. Since the chemical or biological agent tends to be hydrophobic on contact with the weakly encapsulated detoxifying solution, the porous coating breaks down and the detoxifying reagent is delivered directly to the chemical or biological agent for maximum concentration at the point of need.Type: ApplicationFiled: February 26, 2002Publication date: August 28, 2003Applicant: The Regents of the University of CaliforniaInventors: Dennis M.

Patent number: 6471788Abstract: A method employing oxide film conversion coatings prepared using ferrate (VI) as the oxidizing agent is disclosed. Metal substrates or surfaces, such as aluminum, aluminum alloys or other metals, are contacted with an aqueous solution comprising ferrate (VI) anions to form a corrosion resistant conversion coating on the surface thereof. The ferrate anion concentration is preferably between about 0.0166% and about 1.66% by weight. The coating process is carried out by dipping, spraying, or painting at temperatures ranging from 25° C. to 100° C. for a period of time ranging from about 1 second to about 5 minutes.Type: GrantFiled: December 15, 1999Date of Patent: October 29, 2002Assignee: Lynntech Coatings, Ltd.Inventors: Zoran Minevski, Jason Maxey, Carl Nelson, Cahit Eylem

Publication number: 20020119086Abstract: A process is described for regenerating an at least partly reduced catalytic redox solution, whereby said process includes at least one complexing agent of a polyvalent metal that is associated with the solution in which the solution is circulated in a regeneration zone in the presence of an oxygen-containing gas under appropriate regeneration conditions, and a regeneration effluent is recovered that is at least partly oxidized. The concentration of the oxygen that is dissolved in the regeneration effluent is measured, and the operating parameters are adjusted so as to minimize the degradation of the complexing agent and to regenerate the catalytic solution, at least in part.Type: ApplicationFiled: December 21, 2001Publication date: August 29, 2002Applicant: Institut Francais du PetroleInventors: Thierry Huard, Christian Streicher

Patent number: 6432900Abstract: The invention relates to ligands or complexes useful as catalysts for catalytically bleaching substrates with atmospheric oxygen, and as catalysts in the of treatment of textiles such as laundry fabrics whereby bleaching by atmospheric oxygen is catalysed after the treatment. The ligand is of the general formula: wherein R1, R2, and R3 independently represent a group selected from hydrogen, hydroxyl, halogen, —NH—C(NH)NH2, —R and —OR, wherein R=alkyl, alkenyl, cycloalkyl, heterocycloalkyl, aryl, heteroaryl or a carbonyl derivative group, R being optionally substituted by one or more functional groups, and provided that two of R1, R2 and R3 are coordinating groups and one of R1, R2 and R3 is a non-coordinating group; Q independently represents a group selected from C2-3-alkylene optionally substituted by H, benzyl or C1-8-alkyl; and Q1, Q2 and Q3 independently represent specified linking groups.Type: GrantFiled: August 29, 2000Date of Patent: August 13, 2002Assignee: Unilever Home & Personal Care USA, Division of Conopco, Inc.Inventors: Adrianus Cornelis Appel, Ronald Hage, David Tetard, Robin Stefan Twisker
