Publication number: 20120301516Abstract: Porous materials and methods for forming them are disclosed. One method for immobilizing micro-particles and/or nano-particles onto internal pore surfaces and/or external pore surfaces of porous materials includes suspending the micro-particles and/or nano-particles in a liquid adapted to swell, soften, and/or deform either the porous materials and/or the particles, thereby forming a liquid-particle suspension. The method further includes adding the suspension to the porous materials; and removing the liquid, thereby forming the porous materials having the micro-particles and/or nano-particles immobilized on the internal pore surfaces and/or the external pore surfaces.Type: ApplicationFiled: August 2, 2012Publication date: November 29, 2012Inventors: Peter X. Ma, Guobao Wei

Patent number: 8314231Abstract: Methods for depolymerizing polysaccharides are disclosed. In certain exemplary methods, polysaccharides having a first average molecular weight can be reacted with hydroxyl free radicals to produce polysaccharides having a second average molecular weight lower than the first average molecular weight. The hydroxyl free radicals can be formed by interaction of an oxidant with a catalyst comprising a polydentate ligand complexed with a metal ion. In certain exemplary embodiments, the oxidant can be hydrogen peroxide, and the catalyst can be iron methylglycine diacetate or iron-2,3,4,5,6 pentahydroxyhexanoate.Type: GrantFiled: May 1, 2008Date of Patent: November 20, 2012Assignee: Hydrite Chemical Co.Inventors: Marc A. Baures, Charles Alfred Krier, Henry W. Cox

Patent number: 8314219Abstract: C-glycoside keto-amide derivatives, including C-glycoside keto-hydrazones and C-glycoside keto-oximes, may be prepared from plant or animal lipids and saccharides. These C-glycoside keto-amide derivatives are of the formula: wherein: R is a saccharide; Y is independently selected from H or a halogen; m is an integer greater than or equal to 1; X is NH (as in C-glycoside keto-hydrazones) or O (as in C-glycoside keto-oximes); and R2 is an acyl moiety derived from any lipid fatty acid of the formula —C(O)—R3, wherein R3 is a C5 to C22 straight or branched chain hydrocarbon which may be saturated or unsaturated. These C-glycoside keto-amide derivatives have potential applications as surfactants, detergents, liposomes, and bilayers.Type: GrantFiled: May 11, 2010Date of Patent: November 20, 2012Assignee: The United States of America as represented by the Secretary of AgricultureInventor: Neil P Price
