  • Publication number: 20130330477
    Abstract: A mechanochemical oxidation process that allows relatively benign oxidizers to be used for the production of at least partially oxidized graphite, and a method of preparing a carbon fiber using oxidized graphite and a fiber component. Partially oxidized graphite is fully dispersible in water and can be used to prepare thin films with conductivities rivaling pure graphite. This offers the potential for improved electronic displays, solar cells, and lithium ion batteries. A carbon nanotube and a method of making the same is also provided.

  • Publication number: 20130302597
    Abstract: The present invention relates to a method for manufacturing a film of Cu2ZnSnS4 (CZTS) on a metal or metal oxide substrate by successive ion layer adsorption and reaction (SILAR), characterized by the fact that it comprises at least two cycles, each cycle comprising the following successive steps: immersion of the substrate in a cationic solution comprising copper sulfate (CuSO4), tin sulfate (SnSO4) and zinc sulfate (ZnSO4), referred to as the precursors; rinsing by immersion of the substrate in deionized water; immersion of the substrate in an anionic solution comprising sodium sulfide (Na2S); rinsing by immersion of the substrate in deionized water; the concentration ratio of the copper (Cu2+), zinc (Zn2+) and tin (Sn2+) cations and of the sulfur (S2?) anion is 1:1:1:1 or 1:0.5:0.5:1. The invention will be applicable more particularly in the photovoltaic field, especially for production of thin-film, especially nanostructured photovoltaic cells, such as the ETA (Extremely Thin Absorber) cell.

  • Publication number: 20130065076
    Abstract: A method for applying a protective coating to gas turbine engine components using a saturated solution of nickel acetate tetrahydrate, applying a uniform thickness of the coating onto the thermal barrier coating of selected components, and heat treating the coated component in air at a temperature sufficient to form a protective layer of NiO. The saturated NiO solution has sufficient solubility to penetrate into the microscopic cracks of the thermal barrier coating to form a “sacrificial mitigation layer” of NiO that substantially inhibits the reaction between vanadium pentoxide and yttria-stabilized compounds present in the thermal barrier coating.
