摘要:A Cu-amine complex of hydrated copper sulfate and ethylene diamine or an oligomer of ethylene diamine is employed in a direct (one-pot) synthesis of a copper-cation containing silicoaluminophosphate (SAPO) zeolite material having the Cu/SAPO-34 structure. The copper-amine complex is included in an aqueous gel of precursors of the SiO 2 , Al 2 O 3 , and P 2 O 5 constituents, which are mixed, aged, and thermally treated to form the desired Cu/SAPO-34 structure. The synthesized Cu/SAPO-34 material is demonstrated to be an effective catalyst material in conversion of nitric oxide to nitrogen (using ammonia as a reductant) in synthetic exhaust streams characteristic of diesel engine and other lean-burn vehicle engine exhaust streams.

标题:Toxin/antitoxin systems and methods for regulating cellular growth, metabolic engineering and production of recombinant proteins
发明人：NIKOLSKY YURI; BAEV MARK
权利人:MAZEF BIOSCIENCES LLC
摘要:The present invention provides compositions and method for regulating cellular growth and metabolism, intra- and extracellular enzymatic activities, and synthesis of endogenous and/or heterologous proteins, comprising the steps of cloning genes encoding an mRNA interferase (toxin) and its cognate antitoxin; expressing these proteins in a host cell from two separate constitutive or inducible promoters on one or more plasmid vectors or on a chromosome; and regulating the cellular growth and metabolism by controlling the ratio of toxin and antitoxin present in the host cell. Optionally, the method provides further steps of modifying an endogenous or heterologous gene of interest to substitute all mRNA recognition sequences with sequences that are not cleavable by the mRNA interferase being expressed without any change in the amino acid sequence of the protein encoded by the gene; and co-expressing the gene of interest in the same host cell.

摘要:The present invention relates to cosmetic or dermatological compositions containing PQQ or its esters, methods of treating or promoting skin changes by topical application of these compositions, and methods of synthesis of PQQ esters. The PQQ ester-containing compositions of the present invention are unexpectedly effective in treating skin, particularly with respect to skin tolerance. When included in a topical composition, the PQQ esters of the present invention have an antioxidant effect that is useful in treating a skin change.

标 题:Synthesis of dendritic polyolefins by metathesis insertion polymerization

权利人:YANG YONG; TSOU ANDY HAISHUNG; EXXONMOBIL RES & ENG CO
摘要:A one step process for making a dendritic hydrocarbon polymer, e.g., dendritic polyolefin, by metathesis insertion polymerization. The process comprises polymerizing an amount of one or more cyclic olefins and one or more multi-functional (meth)acrylates in the presence of a metathesis catalyst and under conditions sufficient to produce the dendritic hydrocarbon polymer. The one or more multi-functional (meth)acrylates have a functionality of 3 or higher. The dendritic hydrocarbon polymer can be hydrogenated to produce a substantially saturated dendritic hydrocarbon polymer. The hydrogenation can take place in the same reaction vessel as the polymerization, i.e., one pot process.

权利人:SEOUL NAT UNIV R&DB FOUNDATION; PEROLED CO LTD
摘要:The present inventive concept relates to an in situ core/shell perovskite nanocrystal film formed by an in situ nanocrystal synthesis process, a method for producing the same, and a light emitting device comprising the same as a light-emitting layer. The in situ core/shell perovskite nanocrystal film formed by the in situ nanocrystal synthesis process according to the present inventive concept exhibits a strong charge confinement effect by nanocrystal formation, and can simultaneously greatly improve the luminescence efficiency and lifetime by maintaining the fast charge transport capability of polycrystalline perovskite.
