摘要:聚(甲基丙烯酸)和烷基三甲基溴化铵,C N/tab,阳离子表面活性剂之间的相互作用已通过使用芘及其衍生物的光物理学在 Ph 8 的水溶液中进行了研究.这些荧光探针的光物理研究,包括稳态和脉冲激光研究,表明 Pma 的构象转变是由 C N/tab 诱导的.表面活性剂诱导 Pma 链在 Ph 值为 8 时卷曲,这是通过协同过程发生的.当 C N/tab 的浓度高于临界聚集浓度 Cac 时,就会发生这种效应.Cac 比相应胶束的 Cmc 小 1 或 2 个数量级.表面活性剂链长和 Pma 浓度对 Cac 有显着影响,它提供了有关 Cac 的性质和 Pma 过渡机制的信息.基于实验数据,提出了一种用于聚合 Pma-C 10/tab 的模型.研究表明,该聚集体由大约 100 个 C 10/tab 分子和 1 个卷曲聚合物链组成.

摘要:Highly uniform and thin silver nanowires are described having average diameters below 20 nm and a small standard deviation of the diameters. The silver nanowires have a high aspect ratio. The silver nanowires can be characterized by a small number of nanowires having a diameter greater than 18 nm as well as with a blue shifted narrow absorption spectrum in a dilute solution. Methods are described to allow for the synthesis of the narrow uniform silver nanowires. Transparent conductive films formed from the thin, uniform silver nanowires can have very low levels of haze and low values of ΔL*, the diffusive luminosity, such that the transparent conductive films can provide little alteration of the appearance of a black background.

摘要:The present invention pertains to a novel process of manufacturing the compound 2,3,3,3-tetrafluoropropene (1234yf). The compound 1234yf is the newest refrigerant with zero OPD (Ozone Depleting Potential) and zero GWP (Global Warming Potential). Thus, the invention relates to a process, involving a carbene generation route, for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf), of the compound 243db (2,3-dichloro-1,1,1-trifluoropropane), and optionally of the compound 2-chloro-1,1,1-trifluoropropene (1233xf) via carbene route and compound 243db (2,3-dichloro-1,1,1-trifluoropropane). The invention also relates to a process for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf), wherein the compound 243db (2,3-dichloro-1,1,1-trifluoropropane) serves as a starting material, for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf). Further, the invention relates to a process for the manufacture of the compound 2,3,3,3-tetrafluoropropene (1234yf), and of the compound 243db (2,3-dichloro-1,1,1-trifluoropropane), the initial starting materials are selected from the group consisting of com-pound 123 (2,2-dichloro-1,1,1-trifluoroethane), compound 124 (2-chloro-1,1,1,2-tetrafluoroethane), and compound 125 (pentafluoroethane).

摘要:4-Cyano-2-azetidinone derivatives represented by the formula ##STR1## wherein R 1 is an amino group which may be acylated or protected, X is a hydrogen atom or a methoxy group and W is a hydrogen atom or a sulfo group, and methods of producing the same, for example, as represented by ##STR2## wherein R 2 is an acylated or protected amino group, Y is a halogen atom or a group having the formula --OCOR 3 , --SCOR 3 or --S(O) n --R 3 (R 3 being a hydrocarbyl group and n an integer 1 or 2), R 4 is an amino group which may be acylated or protected and X is as defined above. Compounds [I] are useful as advantageous intermediates for the synthesis of optically active 4-substituted-2-azetidinone derivatives, and, when W=SO 3 H, [I] are also useful as antimicrobial agents and as beta-lactamase inhibitors.
