摘要:A method of forming bimetallic core-shell metal nanoparticles including a core of a first metal material and a shell of a second metal material, the method including photochemically producing metallic nanoparticle cores of the first metal material, and forming a shell of the second metal material around the cores. The shell can be formed by adding shell-forming precursor materials to a solution or suspension of the cores and photochemically forming the shells around the cores, or by separately photochemically producing metallic nanoparticles of the second metal material and mixing the metallic nanoparticles of the second metal material and the metallic nanoparticle cores to cause the metallic nanoparticles of the second metal material to form a shell around the metallic nanoparticle cores.

摘要:The synthesis of 4-, 4-(1,1)-and 3,5-substituted N-alkyl-pyridinium salts as well as of 2-carboxamide substituted N(1,4)diazinium compounds are described. The N-surfactants obtained have a small critical micelle concentration (CMC) of 10-5 -10-7 Mol/Liter. These surfactants produce micells of different size and form depending on the nature of the anions. 4-(1,1)-substituted and 3,5-substituted N-alkyl-pyridinium components are capable of forming vesicles in equeous solutions of different forms and sizes. The N-surfactants synthesized can be used as pharmaceuticals.

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).
