    摘要: A nanoelectronic device includes a nanostructure, such as a nanotube or network of nanotubes, disposed on a substrate. Nanoparticles are disposed on or adjacent to the nanostructure so as to operatively effect the electrical properties of the nanostructure. The nanoparticles may be composed of metals, metal oxides, or salts, and nanoparticles composed of different materials may be present. The amount of nanoparticles may be controlled to preserve semiconductive properties of the nanostructure, and the substrate immediately adjacent to the nanostructure may remain substantially free of nanoparticles. A method for fabricating the device includes electrodeposition of the nanoparticles using one or more solutions of dissolved ions while providing an electric current to the nanostructures but not to the surrounding substrate.

    摘要: This invention provides for an apparatus and a method for operation of a cryogenic hydrogen storage system that contains a porous medium configured to adsorb hydrogen. The hydrogen storage and supply system includes a hydrogen source apparatus and a cryosorptive storage apparatus. Methods and devices that allow for an energy efficient filling of the cryosorptive apparatus from the hydrogen source apparatus are described. The cryosorptive hydrogen storage apparatus is filled with cold, pressurized hydrogen. During the course of filling, heat is generated in the cryosorptive storage device by the process of hydrogen adsorption on to the host medium. Methods and devices are provided for the removal the generated heat and the warm hydrogen. Further provided are devices and methods for the capture and recycle of escaped hydrogen within the hydrogen source apparatus.
