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, a cryosorptive storage apparatus, and a fuel recycle loop. Methods and devices that allow for an energy efficient release of hydrogen from the cryosorptive apparatus are described. At the outset of a fuel release, the cryosorptive hydrogen storage apparatus contains cold, pressurized hydrogen. Release of hydrogen from the storage apparatus is a process that consumes heat, thereby drawing down both the temperature and pressure. Heat can be provided to the cryosorptive storage apparatus by various direct approaches, or through the influx of warm, recycled hydrogen. The hydrogen storage and release apparatus contains a recycle loop, which warms a portion of the effluxing hydrogen, and returns it to the storage apparatus, thereby maintaining pressure and temperature conditions that support continued hydrogen desorption from the storage medium.

摘要： Nanostructure sensing devices for detecting an analyte are described. The devices include nanostructures connected to conductive elements, all on a substrate. Contact regions adjacent to points of contact between the nanostructures and the conductive elements are given special treatment. The proportion of nanostructure surface area within contact regions can be maximized to effect sensing at very low analyte concentrations. The contact regions can be passivated in an effort to prevent interaction between the environment and the contact regions for sensing at higher analyte concentrations and for reducing cross-sensing. Both contact regions and at least some portion of the nanostructures can be covered with a material that is at least partially permeable to the analyte of interest and impermeable to some other species to tune selectivity and sensitivity of the nanostructure sensing device.

摘要： A hydrogen storage medium is provided, where the medium is comprised of boron oxide and closely related compounds such as orthoboric acid, metaboric acid, hydrated boric acid, and disodium borohydrate. The medium is substantially an amorphous glassy network, albeit with local regions of order, pores, and networks that provide surface area. Hydrogen is adsorbed by the medium with a heat of adsorption of about 9 kJ/mol to about 13 kJ/mol, a value which is higher than that of the heat of adsorption of hydrogen on carbon. The value for the heat of adsorption of hydrogen on the inventive storage medium is provided by computation, and corroborated by experimental observation. The higher heat of adsorption of the medium provides for operation at temperatures higher temperatures higher than those provided by carbon. Further provided are methods by which the storage medium can be prepared in such a form so as to permit high capacity hydrogen storage, as well as an apparatus, with the inventive medium disposed therein, for storing hydrogen.
