标题 :A method for synthesis of carbon-silica-metal composite and combination thereof
发明人：P R RAMKUMAR
权利人:P R RAMKUMAR; ANNA UNIV CHENNAI
摘要:The present invention is a facile and template based synthesis method for carbon-5 silica xerogel or carbon-silica aerogel type composites with uniformly distributed metal or metal oxide nanoparticles embedded inside their structure. The method gives high yield with almost all the synthesized metal or metal oxide nanoparticles loaded into the carbon-silica xerogel or carbon-silica aerogel composite structure by in-situ one-pot synthesis procedure. Embedded metal or metal-oxide 10 nanoparticles are three dimensionally covered by carbon coating. This method can also be used to produce carbon-silica xerogel or carbon-silica aerogel composite template based novel hollow granular shell carbon xerogel or hollow granular shell carbon aerogel with highest specific surface area. This method can also be scaled to large amount for various products through one line of synthesis process, 15 showing the potential for industrial scale prospects.

标 题 :Imprint-coating synthesis of selective functionalized ordered mesoporous sorbents for separation and sensors

权利人:UNIV TENNESSEE RES CORP; U T BATTELLE LLC
摘要:The present invention relates generally to mesoporous sorbent materials having high capacity, high selectivity, fast kinetics, and molecular recognition capability. The invention also relates to a process for preparing these mesoporous substrates through molecular imprinting techniques which differ from convention techniques in that a template molecule is bound to one end of bifunctional ligands to form a complex prior to binding of the bifunctional ligands to the substrate. The present invention also relates to methods of using the mesoporous sorbent materials, for example, in the separation of toxic metals from process effluents, paints, and other samples; detection of target molecules, such as amino acids, drugs, herbicides, fertilizers, and TNT, in samples; separation and/or detection of substances using chromatography; imaging agents; sensors; coatings; and composites.

标 题:Methods of making MOFs, systems for synthesizing MOFs, and methods of coating textiles with MOFs
发明人：GIRI GAURAV; HUELSENBECK LUKE
权利人:UNIV VIRGINIA PATENT FOUNDATION
摘要:A method of synthesis of metal organic frameworks (“MOFsâ€?) includes preparing a metal solution by dissolving at least one metal salt in an aqueous solution and buffering the metal solution with a base to achieve a first pH, the metal solution optionally comprising an organic co-solvent, preparing a linker solution by adding at least one organic acid linker and at least one base to an aqueous solution, and mixing the metal solution and the linker solution to produce the MOFs. The at least one organic acid linker has an ability to be protonated or deprotonated in response to a second pH, and the mixture of the metal solution and the linker solution has a third pH value, where the third pH value is greater than a highest pKa of the organic acid linker. The MOFs may be applied to a textile.

摘要:PCT No. PCT/JP94/01049 Sec. 371 Date Jun. 21, 1995 Sec. 102(e) Date Jun. 21, 1995 PCT Filed Jun. 29, 1994 PCT Pub. No. WO95/01323 PCT Pub. Date Jan. 12, 1995An object of the present invention is to provide a safe method of commercially producing optically active aminoalcohol derivatives, which serve as intermediates for the synthesis of medicinal chemicals such as the immunopotentiating anticancer agent bestatin, in a simple and easy manner in high yields and with high levels of selectivity. The present invention consists in a method of producing 3-amino-1-nitro-4-phenyl-2-butanol derivatives of the general formula (1) wherein R1 and R2 each independently represents a hydrogen atom or an amino group protecting group, and a method of producing 3-amino-2-hydroxy-4-phenylbutyric acid derivatives derivable therefrom.

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.

标题 :Synthesis of polycarbonate from dialkyl carbonate and bisphenol diester
发明人：BOLON DONALD A; HALLGREN JOHN E
权利人:GEN ELECTRIC
摘要:Polycarbonates are formed by the interaction of a bisphenol diester, carbon monoxide and oxygen. The initial polycarbonate product is an oligomer which, upon heat treatment, polymerizes to a high molecular weight polycarbonate. The products produced according to the present invention are chainstopped prior to heat treatment, making them less thermally and oxidatively sensitive.
