    Abstract: Copper(II) acetate, zinc(II) acetate, and tin(IV) acetate are weighed so that the total amount of metal ions is 2.0×10?4 mol and the molar ratio of ions is Cu:Zn:Sn=2:1:1, and 2.0 cm3 of oleylamine is added to prepare a mixed solution. Apart from this, 1.0 cm3 of oleylamine is added to 2.0×10?4 mol of sulfur powder to prepare a mixed solution. These mixed solutions are separately heated at 60° C. and mixed at room temperature. The pressure in a test tube is reduced, followed by nitrogen filling. The test tube is heated at 240° C. for 30 minutes and then allowed to stand until room temperature. The resultant product is separated into a supernatant and precipitates by centrifugal separation. The separated supernatant is filtered, methanol is added to produce precipitates. The precipitates are dissolved by adding chloroform to prepare a semiconductor nanoparticle solution.

  • Patent number: 8728429
    Abstract: In certain implementations, a method of manufacturing electrically conductive nanodiamond particles involves providing at least one type of carbon-containing explosive material and at least one type of non-explosive material; wherein the non-explosive material contains at least one or more than one element or species other than nitrogen that serve as a nanodiamond dopant; mixing the carbon containing explosive material with the non-explosive material; detonating the mixture under conditions of negative oxygen balance in the presence of a cooling medium; purifying the product of detonation from incombustible impurities; and carrying out additional processing for activation or enhancement of electrical conductance. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.

  • Patent number: 8623220
    Abstract: A simple, room-temperature method of producing CuO-doped zinc oxide nanoparticles was established by reacting zinc nitrate hexahydrate, copper nitrate trihydrate and cyclohexylamine (CHA) at room temperature. These nanoparticles may be used for photocatalytic degradation of cyanide in aqueous solutions. The degradation of cyanide is effective because electrons transfer from the p-type copper oxide to the n-type zinc oxide.
