  • Patent number: 8044293
    Abstract: A thermoelectric device includes a nanocomposite material with nanowires of at least one thermoelectric material having a predetermined figure of merit, the nanowires being formed in a porous substrate having a low thermal conductivity and having an average pore diameter ranging from about 4 nm to about 300 nm.
    Type: Grant
    Filed: February 15, 2006
    Date of Patent: October 25, 2011
    Assignee: GM Global Technology Operations LLC
    Inventors: Jihui Yang, Dexter D. Snyder
  • Patent number: 7443003
    Abstract: An information storage device includes a substrate and a shape memory alloy film established on the substrate. The shape memory alloy film may receive, supply, and store digital information. One or more thermoelectric modules is/are nanoimprinted between the substrate and the shape memory alloy film. The thermoelectric modules(s) is adapted to selectively erase at least some of the digital information from the shape memory alloy film.

  • Patent number: 5366004
    Abstract: According to a preferred embodiment of this invention, the exterior surface of an evaporator carries a coating of dried paint resistant to microbial growth and suitable for forming an adhered layer on cooling surfaces of an air conditioner. This paint comprises a pigment, a liquid, a binder to promote formation and adherence of the coating after the paint is applied and dried, and a metallic constituent which inhibits microbial growth. Preferably, the metallic constituent is inorganic and includes one or more of: copper, cupric carbonate, cuptic hydroxide, cuptic oxide, cuprous oxide, silver, silver oxide, zinc oxide, and zinc peroxide. The coating is preferably applied to the integral core after assembling and brazing the several plates and fins of the core.

  • Patent number: 5304403
    Abstract: In a preferred method, a zinc-rich alloy coating is applied to a substrate using an electrolysis deposition solution which contains a metal salt of zinc and a metal salt of nickel each in an amount sufficient to provide a weight ratio of zinc to nickel (Zn:Ni) of at least about 1:1; a phosphorus-containing reducing agent in an amount sufficient to cause reduction of the zinc and the nickel to ions thereof; sufficient complexing agent to maintain the nickel ions and the zinc ions in solution; and a buffer in an amount sufficient to achieve a desired pH. Preferably, the surface of the substrate is pretreated or precatalyzed before deposition by a sensitizing step using tin and an activating step using palladium.
