  • Method of synthesizing copper selenide powder
    Patent number: 9656867
    Abstract: This present invention relates to a method of synthesizing copper selenide powder by using a hot-injection method wherein a proper amount of a reducing agent is added to a mixed solution made of copper cationic solution and selenium anionic solution, and the mixed solution is maintained at a temperature of 230° C. for 40 minutes to obtain Copper Selenide powder. The Copper selenide powder, which is in the form of CuSe or Cu2-xSe, can be synthesized by adjusting the amount of the reducing agent being added to the mixed solution.

  • Enameled wire containing a nano-filler
    Publication number: 20100009185
    Abstract: An enameled wire containing a nano-filler includes a metallic wire and at least one layer of insulating coating. At least one layer of the at least one layer of insulating coating includes a nano-filler. The nano-filler is a modified silicon dioxide slurry comprising silicon dioxide, organic solvent and organic silane coupling agent. The nano-filler comprises silicon dioxide modified with an organic silane coupling agent to improve dispersion of the nano-filler and maintain properties of the insulating coating. In addition, material and manufacturing costs of the enameled wire can be lowered.

  • Method of fabricating nano-antifouling boat paint
    Publication number: 20090136441
    Abstract: A nano-scaled antifouling paint for boat is fabricated. A few hydrophobic nano-particles are added into the paint to obtain a nanostructure and a low surface energy. Thus, sea creatures are hard to adhere on the boat or are easily removed. Moreover, owing to a low wettability of the paint, a water drag is reduced when the boat sails, and so fuel is saved.
