  • Bio-enzyme sensor capable of super hydrophobic solid-liquid-gas three-phase coexistence and method for preparing same
    Patent number: 10633686
    Abstract: A bio-enzyme sensor capable of super-hydrophobic solid-liquid-gas three-phase coexistence and a method for preparing the same. The bio-enzyme sensor comprises, from bottom to top, a base material with super-hydrophobic surface, a catalytic material having the function of catalyzing hydrogen peroxide, and bio-enzyme capable of reacting with a substance to be tested to generate hydrogen peroxide. A sufficient amount of oxygen can be provided for enzymatic reaction by forming a state of solid-liquid-gas three-phase coexistence on the surface of the super-hydrophobic material.

  • Methods to fabricate vertically oriented anatase nanowire arrays on transparent conductive substrates and applications thereof
    Patent number: 8835285
    Abstract: The present invention relates to growth of vertically-oriented crystalline nanowire arrays upon a transparent conductive or other substrate for use in 3rd generation photovoltaic and other applications. A method of growing crystalline anatase nanowires includes the steps of: deposition of titania onto a substrate; conversion of the titania into titanate nanowires; and, treatment of the titanate nanowires to produce crystalline anatase nanowires.

  • Single-crystal nanowires and liquid junction solar cells
    Publication number: 20100139747
    Abstract: A method of making semiconducting oxide nanowire arrays on such as rutile is disclosed wherein a substrate is heated in the presence of a reaction mixture of non-polar solvent, semi-conductor metal oxide precursor source and strong acid to produce a nanowire array of a semiconducting oxide on the substrate. Dye sensitized solar cells that employ these nanowire arrays also are disclosed.
