20050261380 - Method for producing polyorganosiloxane particles and for producing silica particles: The present invention provides a method for producing polyorganosiloxane particles through the step of hydrolyzing and condensing a silicon compound having a non-hydrolyzable group and a hydrolyzable alkoxyl group bonded to its silicon atom in the presence of a catalyst and thereby forming seed particles of polyorganosiloxane particles to obtain...

20050261381 - Nanoparticulate anionic clays: where M1+ is a mono-valent metal; M2+ is a divalent metal; and M3+ is a trivalent metal; A is an inorganic or organic anion, chosen such that the rule of charge neutrality is obeyed; n is an integer; x is any rational number between 0 and 1; and y is...

20050256211 - Patient oxygenation using stabilized fluorocarbon emulsions: Storage stable fluorocarbon emulsions having a continuous aqueous phase and a discontinuous fluorocarbon phase, in which the fluorocarbon phase comprises a major amount of a first fluorocarbon or fluorocarbon mixture, and a minor amount of a second fluorocarbon or fluorocarbon mixture, in which the second fluorocarbon has a molecular weight...

20050250856 - Ionic colloidal crystals: Ionic colloidal crystals (ordered multicomponent colloids formed by attractive electrostatic interactions) may be produced by controlling the surface potential and relative size of multiple populations of colloidal particles in suspension. Such suspensions are dried or otherwise caused to precipitate out the particles in ordered arrays. The crystal structure of the...

20050250857 - Gelling agents: The invention relates to a novel class of gelling agents, to a process of preparing said agents, to the use of said agents to prepare gels, and to the gels thus obtained. A gelling agent or thickener according to the invention comprises a core which is functionalized with three amino...

20050250858 - Additives for water-resistant gypsum products: Emulsions are provided which are useful in imparting water-resistance to gypsum products. In one embodiment, the emulsions comprise at least one wax, an alkyl phenol, a salt of polynaphthalenesulfonic acid, and a complexed starch. Emulsions of this embodiment may be added to hot, even boiling, water without the emulsion separating...

20050250859 - Colloidal system of ceramic nanoparticles: A colloidal system of ceramic nanoparticles in a dispersion medium is characterized in that the nanoparticles dispersed in the dispersion medium are distributed by 90% or more portions as unimodal nanoparticles having the same particle size in the dispersion medium, wherein the particle size variation decreases from 50%, related to...

20050250860 - Method and systrem for combating the formation of emulsions: A system (1) for combating the formation of emulsions in production fluid has a control system which compares the volumetric flow rates of oil and water separated from production fluid in a separator vessel (16). When the ratio of the separated oil approaches that where emulsions are expected to form,...

20050250861 - Decomposing surfactant: Use of a compound having a hydrophobic moiety attached to a hydrophilic moiety, wherein the hydrophilic moiety comprises a β-keto acid group and the hydrophobic moiety is attached via a bond from a carbon or an oxygen of the hydrophobic moiety to a carbon of the β-keto acid group, provided...
