    Abstract: The present invention generally discloses the use of a nanostructured non-silicon thin film (such as an alumina or aluminum thin film) on a supporting substrate which is subsequently coated with an active layer of a material such as silicon or tungsten. The base, underlying non-silicon material generates enhanced surface area while the active layer assists in incorporating and transferring energy to one or more analytes adsorbed on the active layer when irradiated with a laser during laser desorption of the analyte(s). The present invention provides substrate surfaces that can be produced by relatively straightforward and inexpensive manufacturing processes and which can be used for a variety of applications such as mass spectrometry, hydrophobic or hydrophilic coatings, medical device applications, electronics, catalysis, protection, data storage, optics, and sensors.

    Abstract: The present invention is directed to nanowire structures and interconnected nanowire networks comprising such structures, as well as methods for their production. The nanowire structures comprise a nanowire core, a carbon-based layer, and in additional embodiments, carbon-based structures such as nanographitic plates consisting of graphenes formed on the nanowire cores, interconnecting the nanowire structures in the networks. The networks are porous structures that can be formed into membranes or particles. The nanowire structures and the networks formed using them are useful in catalyst and electrode applications, including fuel cells, as well as field emission devices, support substrates and chromatographic applications.

    Abstract: Systems and methods to fabricate macroelectronic light emitting devices using densely oriented nanowires are disclosed. In one embodiment, core nanowires are synthesized and an insulating shell is fabricated around the nanowires. The nanowire core-shell structures are then deposited on a substrate to create a densely oriented nanowire thin film. Once the densely oriented nanowire thin film is created, a metal-insulator nanowire structure is fabricated by layering a metal on the nanowire thin film. Ohmic contacts are then created on the metal-insulator nanowire structure for operation. Application of electrical signals to the ohmic contacts causes light emission from the metal-insulator nanowire structure. Light emitting devices having densely oriented nanowire thin films are also disclosed. In an embodiment the light emitting device is, for example, a LED. The nanowires can include, for example, GaN, InP, CdS nanowires or a combination of these and other nanowires. Different colors of light can be produced based on the type of nanowire, the combination of nanowire types and the physical characteristics of the nanowires.
