Abstract: A method of fabricating metallic Cu nanowires with lengths up to about 25 μm and diameters in a range 20-100 nm, or greater if desired. Vertically oriented or laterally oriented copper oxide structures (CuO and/or Cu2O) are grown on a Cu substrate. The copper oxide structures are reduced with 99+ percent H or H2, and in this reduction process the lengths decrease (to no more than about 25 μm), the density of surviving nanostructures on a substrate decreases, and the diameters of the surviving nanostructures have a range, of about 20-100 nm. The resulting nanowires are substantially pure Cu and can be oriented laterally (for local or global interconnects) or can be oriented vertically (for standard vertical interconnects).

Abstract: A method for providing for thermal conduction using an array of carbon nanotubes (CNTs). An array of vertically oriented CNTs is grown on a substrate having high thermal conductivity, and interstitial regions between adjacent CNTs in the array are partly or wholly filled with a filler material having a high thermal conductivity so that at least one end of each CNT is exposed. The exposed end of each CNT is pressed against a surface of an object from which heat is to be removed. The CNT-filler composite adjacent to the substrate provides improved mechanical strength to anchor CNTs in place and also serves as a heat spreader to improve diffusion of heat flux from the smaller volume (CNTs) to a larger heat sink.

Abstract: Method for providing a nanopipette array for biosensing applications. A thin substrate of anodizable metal (“AN-metal,” such as Al, Mg, Zn, Ti, Ta and/or Nb) is anodized at temperature T=20-200° C., chemical bath pH=4-6 and electrical potential 1-300 Volts, to produce an array of anodized nanopipette channels, having diameters 10-50 nm, with oxidized channel surfaces of thickness 5-20 nm. A portion of exposed non-oxidized AN-metal between adjacent nanopipette channels, of length 1-5 μm, is etched away, exposing inner and outer surfaces of a nanopipette channel. A probe molecule, is deposited on one or both surfaces to provide biosensing capability for K(≧1) target molecules. Target molecule presence, in an above-threshold concentration, in a fluid passed through or adjacent to a nanopipette channel, produces characteristic detection signals associated with the probe molecule site.

Abstract: Methods for forming variable diameter nanowires enable a variety of applications. The top of the nanowires can provide a surface area that is suitable for the deposition of an electrode. In addition variable diameter nanowires can have a frequency response that is dependent upon the nanowire diameter. Nanowires having multiple diameters can have a broader bandwidth of resonance frequencies than a uniform diameter nanowire.

Abstract: Method and system for functionalizing a collection of carbon nanotubes (CNTs). A selected precursor gas (e.g., H2 or F2 or CnHm) is irradiated to provide a cold plasma of selected target species particles, such as atomic H or F, in a first chamber. The target species particles are directed toward an array of CNTs located in a second chamber while suppressing transport of ultraviolet radiation to the second chamber. A CNT array is functionalized with the target species particles, at or below room temperature, to a point of saturation, in an exposure time interval no longer than about 30 sec. *Discrimination against non-target species is provided by (i) use of a target species having a lifetime that is much greater than a lifetime of a non-target species and/or (2) use of an applied magnetic field to discriminate between charged particle trajectories for target species and for non-target species.

Abstract: A novel method for simultaneously forming and filling and decorating carbon nanotubes with palladium nanoparticles is disclosed. Synthesis involves preparing a palladium chloride (PdCl2) solution in a container, having two graphite electrodes, then immersing the graphite electrode assembly, into the PdCl2 solution; connecting the graphite electrodes to a direct current power supply; bringing the electrodes into contact with each other to strike an arc; separating the electrodes to sustain the arc inside the solution; putting the container with electrode assembly in a water-cooled bath; and collecting Pd-nanoparticles encapsulated in carbon nanotubes and carbon nanotubes decorated with Pd-nanoparticles. The temperature at the site of the arc-discharge is greater than 3000° C. At these temperatures, the palladium is ionized into nanoparticles and the graphite electrodes generate layers of graphene (carbon), which roll away from the anode and encapsulate or entrap the Pd-nanoparticles. The unique nanotube structures have significant commercial potential as gas sensors or as a means for hydrogen storage.

Abstract: A method and system for evaluating status and response of a mineral-producing field (e.g., oil and/or gas) by monitoring selected chemical and physical properties in or adjacent to a wellsite headspace. Nanotechnology sensors and other sensors are provided for one or more underground (fluid) mineral-producing wellsites to determine presence/absence of each of two or more target molecules in the fluid, relative humidity, temperature and/or fluid pressure adjacent to the wellsite and flow direction and flow velocity for the fluid. A nanosensor measures an electrical parameter value and estimates a corresponding environmental parameter value, such as water content or hydrocarbon content. The system is small enough to be located down-hole in each mineral-producing horizon for the wellsite.
