    摘要： A flexible electronic device is made up of nanostructures. Specifically, the device includes a flexible substrate, a film of nanostructures in contact with the flexible substrate, a first conducting element in contact with the film of nanostructures, and a second conducting element in contact with the film of nanostructures. The nanostructures may comprise nanotubes, such as carbon nanotubes disposed along the flexible substrate, such as an organic or polymer substrate. The first and second conductive elements may serve as electrical terminals, or as a source and drain. In addition, the electronic device may include a gate electrode that is in proximity to the nanotubes and not in electrical contact with the nanotubes. In this configuration, the device can operate as a transistor or a FET. The device may also be operated in a resistive mode as a chemical sensor (e.g., for sensing NH3).

    摘要： An electronic system for selectively detecting and identifying a plurality of chemical species, which comprises an array of nanostructure sensing devices, is disclosed. Within the array, there are at least two different selectivities for sensing among the nanostructure sensing devices. Methods for fabricating the electronic system are also disclosed. The methods involve modifying nanostructures within the devices to have different selectivity for sensing chemical species. Modification can involve chemical, electrochemical, and self-limiting point defect reactions. Reactants for these reactions can be supplied using a bath method or a chemical jet method. Methods for using the arrays of nanostructure sensing devices to detect and identify a plurality of chemical species are also provided. The methods involve comparing signals from nanostructure sensing devices that have not been exposed to the chemical species of interest with signals from nanostructure sensing devices that have been exposed to the chemical species of interest. Nanostructure sensing device array structures that can measure and subtract out environmental factors are also disclosed.

    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.

    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.
