专利信息 专利号:US-11634341-B2 优先权日:2016-02-04 标 题 :Nanolog and nanoparticles and method of formation 发明人:KOSSOY ANNA; AGUF VLADIMIR; MARGOLIN ALEXANDER 权利人:NANOTECH IND SOLUTIONS INC; NANOTECH IND SOLUTIONS 摘要:A nanostructure is provided that in one embodiment includes a cluster of cylindrical bodies. Each of the cylindrical bodies in the cluster are substantially aligned with one another so that their lengths are substantially parallel. The composition of the cylindrical bodies include tungsten (W) and sulfur (S), and each of the cylindrical bodies has a geometry with at least one dimension that is in the nanoscale. Each cluster of cylindrical bodies may have a width dimension ranging from 0.2 microns to 5.0 microns, and a length greater than 5.0 microns. In some embodiments, the cylindrical bodies are composed of tungsten disulfide (WS2). In another embodiment the nanolog is a particle comprised of external concentric disulfide layers which encloses internal disulfide folds and regions of oxide. Proportions between disulfide and oxide can be tailored by thermal treatment and/or extent of initial synthesis reaction. 专利号:CN-109912399-A 优先权日:2019-03-01 标 题:The method of high-pressure synthesis 2- phenylpropionic acid 专利号:CN-118667139-B 优先权日:2024-07-02 标 题:Synthesis method of polycarbonate polyol with main chain containing carbamate structure 专利号:CN-113444469-B 优先权日:2021-07-14 标 题 :Synthesis process of a kind of highly elastic photocurable acrylic foam tape 专利号:CN-115746715-A 优先权日:2022-11-30 标题 :A kind of high temperature resistant UV curing peelable elastic adhesive and its synthesis process 专利号:CN-114196097-B 优先权日:2022-01-29 标 题:A kind of regenerated wooden sponge for hydroponic planting and its synthesis method全部 工厂 研发
