    摘要： The present invention provides a nanocrystal tandem catalyst comprising at least two metal-metal oxide interfaces for the catalysis of sequential reactions. One embodiment utilizes a nanocrystal bilayer structure formed by assembling sub-10 nm platinum and cerium oxide nanocube monolayers on a silica substrate. The two distinct metal-metal oxide interfaces, CeO2—Pt and Pt—SiO2, can be used to catalyze two distinct sequential reactions. The CeO2—Pt interface catalyzed methanol decomposition to produce CO and H2, which were then subsequently used for ethylene hydroformylation catalyzed by the nearby Pt—SiO2 interface. Consequently, propanal was selectively produced on this nanocrystal bilayer tandem catalyst.

    摘要： A nanowire switching device and method. The device has a nanowire structure comprising an elongated member having a cross-sectional area ranging from about 1 nanometers but less than about 500 nanometers, but can also be at other dimensions, which vary or are substantially constant or any combination of these. The device also has a first terminal coupled to a first portion of the nanowire structure; and a second terminal coupled to a second portion of the nanowire structure. The second portion of the nanowire structure is disposed spatially from the first portion of the nanowire structure. An active surface structure is coupled to the nanowire structure. The active surface structure extends from the first portion to the second portion along the elongated member.
