  • Patent number: 11043678
    Abstract: Improved oxygen reduction reaction catalysts include octahedral nanoparticles of a platinum-copper-nickel alloy contacted by a secondary ionomer. The alloy can have a formula of Pt2CuNi, and the secondary ionomer can include an ionic liquid, 1-methyl-2,3,4,6,7,8-hexahydro-1H-pyrimido[1,2-a]pyrimidin-9-ium 1,1,2,2,3,3,4,4,4-nonafluorobutane-1-sulfonate ([MTBD][C4F9SO3]). The oxygen reductions catalysts have improved stability, as well as mass area and specific area comparted to competing catalysts.

  • Patent number: 7790060
    Abstract: Silicon oxide and electrically conductive doped silicon materials are sintered in a protective environment to yield a composite SiOx:Si material that exhibits the properties of SiOx, and yet is electrically conductive due to the presence of Si. Such a composite material finds many uses, such as a target for DC and/or AC sputtering processes to produce silicon oxide thin films for touch-screen applications, barrier thin films in LCD displays and optical thin films used in a wide variety of applications.

  • Publication number: 20080296149
    Abstract: An AC or DC sputtering target for depositing thin films of chromium sub oxides on a substrate contains oxides of chromium, chromium metal and incorporated oxygen. The target has a resistivity of 200?·cm or less. The target can be made from a combination of oxides of chromium powder and chromium metal, such as in powder form, or can be made starting with 100% chromium oxide or sub oxide material that is subjected to a reducing atmosphere either before or during the process of making the target in order to reduce a fraction of the chromium oxide and/or sub oxide material to chromium metal and retained oxygen. Such a target can enable the sputtering process to be conducted using inert argon gas only to yield a thin film of chromium oxide. This enables the surface of the target to remain in a continuously stable condition and free of the arcing problems associated with using chromium targets and argon and oxygen gas.
