  • Patent number: 9790425
    Abstract: Common approaches to synthesizing alloyed quantum dots employ high-cost, air-sensitive phosphine complexes as the selenium precursor. Disclosed quantum dot synthesis embodiments avoid these hazardous and air-sensitive selenium precursors. Certain embodiments utilize a combination comprising a thiol and an amine that together reduce and complex the elemental selenium to form a highly reactive selenium precursor at room temperature. The same combination of thiol and amine acts as the reaction solvent, stabilizing ligand, and sulfur source in the synthesis of quantum dot cores. A non-injection approach may also be used. The optical properties of the quantum dots synthesized by this new approach can be finely tuned for a variety of applications by controlling size and/or composition of size and composition. Further, using the same approach, a shell can be grown around a quantum dot core that improves stability, luminescence efficiency, and may reduce toxicity.

  • Publication number: 20150139890
    Abstract: A process for preparing a molybdenum sulfide-based catalyst comprises drying a precipitated molybdenum sulfide-based catalyst precursor, for example, a wet filter cake, such that a particulate catalyst precursor, containing from 12 to 15 percent by weight water, is formed. The particulate catalyst precursor is desirably in the form of free-flowing particles. The particulate catalyst precursor is then auto-reduced. A rotary furnace that subjects the catalyst precursor to at least two zones having distinct temperatures may be conveniently used for drying, auto-reduction, or both. The staged drying and auto-reduction steps reduce the tendency of the precursor to self-heat, which is undesirable because it reduces both the activity and selectivity of the final catalyst.

  • Patent number: 9028723
    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: 8501107
    Abstract: An apparatus is provided for generating mercury (II) sulfide from elemental mercury. Elemental mercury is injected into a heated and sealed reaction vessel containing vaporized sulfur. The elemental mercury reacts with at least a portion of the vaporized sulfur to form the mercury (II) sulfide within the reaction vessel. The formed mercury (II) sulfide is then unloaded from the reaction vessel.
