权利人:CALIFORNIA INST OF TECHN
摘要:A method of growing a transition metal dichalcogenide includes providing a substrate and positioning the substrate in a furnace. The method also includes reducing a transition metal compound to produce a plurality of reduced transition metal compounds. The plurality of reduced transition metal compounds is electrostatically aligned on the substrate. The method further includes reacting the plurality of reduced transition metal compounds with a chalcogen precursor to form one or more layers of a transition metal dichalcogenide.

标题 :Method of using synthetic L-Se-methylselenocysteine as a nutriceutical and a method of its synthesis

摘要:A synthesis of and use for L-Se-methylselenocysteine as a nutriceutical is described, based upon the knowledge that L-Se-methylselenocysteine is less toxic than L-selenomethionine towards normal cells. The synthesis proceeds by mixing N-(tert-butoxycarbonyl)-L-serine with a dialkyl diazodicarboxylate and at least one of a trialkylphosphine, triarylphosphine, and phosphite to form a first mixture that includes N-(tert-butoxycarbonyl)-L-serine β-lactone. Methyl selenol or its salt is mixed with the N-(tert-butoxycarbonyl)-L-serine β-lactone to form a second mixture that includes N-(tert-butoxycarbonyl)-Se-methylselenocysteine. The tert-butoxycarbonyl group is removed from the N-(tert-butoxycarbonyl)-Se-methylselenocysteine to form L-Se-methylselenocysteine. This synthesis significantly improves the manufacturability, manufacturing efficiency, and utility of this naturally occurring rare form of organic-selenium. L-Se-methylselenocysteine formed, for example, in this manner may be used as a nutriceutical for supplementation into the diets of humans or animals for various beneficial purposes, such as, for example, to prevent or reduce the risk of developing cancer.

摘要:A method for preparing III-VI 2 nanoparticles and a thin film of polycrystalline light absorber layers. The method for preparing I-III-VI 2 nanoparticles comprises the steps of: (a1) preparing a mixed solution by mixing each element from groups I, III and VI in the periodic table with a solvent; (a2) sonicating the mixed solution; (a3) separating the solvent from the sonicated mixed solution; and (a4) drying the product resulted from the above step (a3) to obtain nanoparticles.
