20080103219 - Nanocrystal/sol-gel nanocomposites: The present invention is directed to solid composites including colloidal nanocrystals within a sol-gel host or matrix and to processes of forming such solid composites. The present invention is further directed to alcohol soluble colloidal nanocrystals useful in formation of sol-gel based solid composites... Agent: Los Alamos National Security, LLC

20080096983 - Heavy oil emulsion stabilizers containing saccharide based emulsion stabilizer: Heavy oil emulsions, comprising decant oils and No. 6, No. 5 and No. 4 oils, and water are stabilized by adding certain saccharide-based esters. Preferably, the saccharide-based esters are naturally-occurring saccharide esters such as gallotannins, saponin, red gum, and the like.... Agent: Thaddius J. Carvis

20080096984 - Partially hydrophobic silicic acid aqueous dispersions: Aqueous dispersions of partly hydrophobic silica exhibit a smooth change in viscosity with pH over a wide pH range, without gelling or exhibiting local maxima. The dispersions have numerous uses, including use in O/W Pickering emulsions.... Agent: Brooks Kushman P.C.

20080090918 - Separation medium, its preparation and its use: A separation medium in macroporous gel form is disclosed which is obtainable by cooling an aqueous solution of at least one gel forming polymer to a temperature, at which the solvent in the system is partially frozen with the dissolved substances concentrated in the non-frozen fraction of the solvent, said... Agent: Mcdermott Will & Emery LLP
