The methods include depositing a solution comprising a block copolymer and a metal salt into one or more square pyramidal nanoholes formed in a substrate, and annealing the substrate to provide a single nanoparticle in each of the one or more square pyramidal nanoholes.
专利号:US-11767388-B1 优先权日:2019-09-18 标 题 :Silicon-functionalized rubber 发明人:ENSIGN SETH CODY; VIELHABER MARGARET FLOOK; JOHNGRASS JENA LYNN; MA LIQING 权利人:GOODYEAR TIRE & RUBBER 摘要:The compatibility between silica fillers and synthetic rubbers which are synthesized utilizing lanthanide-based catalyst systems, such as neodymium catalyst systems can be improved by terminating the polymerization with a vinyl silane terminating agent. In doing so the vinyl silane is allowed to react with the polymer chain ends of the neodymium rubber to functionalize the chain ends of the polymer chains with silicon containing groups. This results in the rubber having better characteristics for utilization in tire rubber formulations, such a tire tread formulations, that exhibit improved wear characteristics and lower rolling resistance. The process for the synthesis of such functionalized polydiene rubber comprises (1) polymerizing a diene monomer in the presence of a lanthanide-based catalyst system, and (2) terminating the polymerization with a vinyl silane terminator. The functionalized polydiene rubber composition made by this method is comprised of a polydiene rubber which is functionalized at its chain ends with a silicon containing group.

专利号:WO-2012001094-A1 优先权日:2010-07-02 标 题 :Selenide powders and manufacturing process 发明人:AMINIAN HOSSEIN 权利人:UMICORE NV; AMINIAN HOSSEIN 摘要:This invention relates to selenide powders for use in dispersions, pastes or inks suitable for the manufacture of photovoltaic cells such as CIGS or CIGSS based solar cells. A synthesis process is proposed for the manufacture of submicron or nanoparticulate powder comprising selenides of a metal or a metal mixture, comprising the steps of: - selecting an oxygen-bearing precursor of said metal or metal mixture; - mixing said oxygen-bearing precursor with an at least stoichiometric amount of selenium; and, - reducing the mixture with H2 at a temperature sufficient to ensure the reaction with the oxygen of the precursor, and the formation of selenides. The powders can be deposited on a substrate and annealed without the need for a separate selenization step. The use of H2Se as a Se source, which is a most toxic gas, is thus avoided.
