标 题 :Enzymatic synthesis of gangliosides
发明人：DEFREES SHAWN
权利人:NEOSE TECHNOLOGIES INC
摘要:This invention provides methods for practical in vitro synthesis of gangliosides and other glycolipids. The synthetic methods typically involve enzymatic synthesis, or a combination of enzymatic and chemical synthesis. One or more of the enzymatic steps is preferably carried out in the presence of an organic solvent.

权利人:Universiti Brunei Darussalam
摘要:A method for synthesis of nanostructured metal oxide powders. The method comprises converting the metallic material into a precipitate of metal hydroxide by an electrochemical reaction and calcinating the metal hydroxide to form the metal oxides. The method of the invention is also used for the development of cermet particulates and topological insulator particles.

标题:Catalyst for the synthesis of alcohol mixtures containing methanol and higher alcohols
摘要:1. Catalyst for the synthesis of alcohol mixtures containing methanol and higer alcohols one the basis of starting catalysts containing copper oxide, zinc oxide and, optionally, aluminium oxide, obtainable either by (a) producing from soluble salts of copper, zinc and, optionally, aluminium (principal constituents) by joint precipitation with promoter compounds in an alkaline medium a precipitate which is calcined after removal of the impurity ions ; or by (b) impregnating a mixture of the oxides of copper, zinc, and, optionally, aluminium, with solutions of the promoter compounds and calcining the resultant product ; wherein the promoter compounds represent compounds of chromium, cerium, lanthanum, manganese, thorium or of combinations of these elements, and wherein at any desired stage of production alkali compounds are added.
