  • Patent number: 9045335
    Abstract: A hydrogen absorbing and desorbing material formed by co-deposition of magnesium with a catalyst for the kinetic absorption and desorption of hydrogen. A hydrogen absorbing and desorbing material formed of an alloy of magnesium with a catalyst for the kinetic absorption and desorption of hydrogen in which the catalyst for the kinetic absorption and desorption of hydrogen forms a dispersed amorphous or nanocrystalline phase in the magnesium. A hydrogen absorbing and desorbing material having a catalytic surface formed by a process comprising the steps of depositing a layer of tantalum on the hydrogen absorbing and desorbing material and depositing a layer of palladium on the layer of tantalum. A hydrogen absorbing and desorbing material comprises a multilayer film having at least two layers of magnesium and at least two layers of catalyst for the kinetic absorption and desorption of hydrogen, in which the multilayer film comprises alternating layers of magnesium and catalyst.

  • Patent number: 7758708
    Abstract: A thin-film composition of nanocrystal molybdenum in an amorphous metallic matrix may be formed by co-sputtering Mo with aluminum or nickel. NEMS cantilevers may be formed from the film. The films exhibit high nanoindentation hardness and a reduction in roughness and intrinsic stress, while maintaining resistivity in the metallic range.

  • Publication number: 20030010411
    Abstract: An Al—Cu—Si—Ge quaternary alloy uses Si—Ge additions to provide a reasonably dense and homogeneous distribution of precipitates. Heterogeneous nucleation on this Si—Ge template is used to enhance both strength and thermal stability. These precipitates are used as a template for heterogeneous precipitation of other hardening phases, particularly the •′ (Al2Cu) phase. Thus, a Si—Ge addition is used to provide a dense template of heterogeneous nucleation sites for subsequent precipitation of Al—Cu precipitates.
