标题 :Synthesis of nanoparticles
发明人:HAUBOLD STEPHAN; HAASE MARKUS; RIWOTZKI KARSTEN; WELLER HORST; MEYSSAMY HEIKE; IBARRA FERNANDO
权利人:CT ANGEWANDTE NANOTECH CAN
摘要:Methods for the preparation of inorganic nanoparticles capable of fluorescence, wherein the nanoparticles consist of a host material that comprises at least one dopant. The synthesis of the invention in organic solvents allows to gain a considerably higher yield compared to the prior art synthesis in water. All kinds of objects can advantageously be marked and reliably authenticated by using an automated method on the basis of a characteristic emission. Further, the size distribution of the prepared nanoparticles is nartower which renders a subsequent size-selected separation process superfluous.

摘要:The invention relates to methods for producing primary, secondary and tertiary amines and corresponding enantiopure or enantioenriched primary or secondary amine products, comprising the steps of reductively aminating a ketone, with a nitrogen auxiliary in the presence of a hydrogenating catalyst and a hydrogenating agent, wherein the reductive animation is performed under the influence of a mild Lewis acid, the mild Lewis acid being present at the onset of the reductive amination in at most 25 mol% of the ketone or the nitrogen auxiliary.

权利人:UNIV BRIGHAM YOUNG
摘要:Methods are described for making a texturized catalyst. The textural promoter may be a high-surface area, high-porosity, stable metal oxide support. The catalyst is manufactured by reacting catalyst precursor materials and support materials in a single, solvent deficient reaction to form a catalyst. The catalyst may be particles or a coating or partial coating of a support surface.

摘要:The compatibility between silica fillers and synthetic rubbers which are synthesized utilizing lanthanide-based catalyst systems, such as neodymium catalyst systems can be improved by terminating the polymerization with a vinyl silane terminating agent. In doing so the vinyl silane is allowed to react with the polymer chain ends of the neodymium rubber to functionalize the chain ends of the polymer chains with silicon containing groups. This results in the rubber having better characteristics for utilization in tire rubber formulations, such a tire tread formulations, that exhibit improved wear characteristics and lower rolling resistance. The process for the synthesis of such functionalized polydiene rubber comprises (1) polymerizing a diene monomer in the presence of a lanthanide-based catalyst system, and (2) terminating the polymerization with a vinyl silane terminator. The functionalized polydiene rubber composition made by this method is comprised of a polydiene rubber which is functionalized at its chain ends with a silicon containing group.
