摘要： A diamond growing by chemical vapor deposition is exposed to a low energy beam of ionized dopant. The ion beam energy is sufficient to implant the dopant in the growing surface of the diamond. This doping method will work well for any dopant that is substantially immobile in the diamond at the temperature necessary for deposition growth.

摘要： Carbon nanotubes grown on nanostructured flake substrates are disclosed. The nanostructured flake substrates include a catalyst support layer and at least one catalyst layer. Carbon nanotubes grown on the nanostructured flake substrates can have very high aspect ratios. Further, the carbon nanotubes can be aligned on the nanostructured flake substrates. Through routine optimization, the nanostructured flake substrates may be used to produce single-wall, double-wall, or multi-wall carbon nanotubes of various lengths and diameters. The nanostructured flake substrates produce very high yields of carbon nanotubes per unit weight of substrate. Methods for making the nanostructured flake substrates and for using the nanostructured flake substrates in carbon nanotube synthesis are disclosed.

摘要： A general approach is provided for producing devices that absorb optical photons (visible to near IR) and performs charge separation with a useful voltage between holes and electrons. These holes and electrons may be collected in electrodes for performing useful work outside the device. The described technology is generally based upon rectification of plasmons (collective electric excitations) generated by absorbing light with tuned metallic antennas. According to some embodiments, the present invention provides a spatial array of nanoscale conductors forming an optical rectenna that responds to an incident light source and generates a current offset that may be rectified by a rectification-inducing material. The present inventors foresee an extensive use of these optical rectennas as photovoltaic devices, as well as a wide interest in diverse fundamental research and applied technologies.

摘要： Energy is stored by injecting fluid into a hydraulic fracture in the earth and producing the fluid hack while recovering power. The method is particularly adapted to storage of large amounts of energy such as in grid-scale electric energy systems. The hydraulic fracture may be formed and treated with resin so as to limit fluid loss and to increase propagation pressure.

摘要： The present invention is generally directed to catalyzed hot stamp methods for polishing and/or patterning carbon nanotube-containing substrates. In some embodiments, the substrate, as a carbon nanotube fiber end, is brought into contact with a hot stamp (typically at 200-800° C.), and is kept in contact with the hot stamp until the morphology/patterns on the hot stamp have been transferred to the substrate. In some embodiments, the hot stamp is made of material comprising one or more transition metals (Fe, Ni, Co, Pt, Ag, Au, etc.), which can catalyze the etching reaction of carbon with H2, CO2, H2O, and/or O2. Such methods can (1) polish the carbon nanotube-containing substrate with a microscopically smooth finish, and/or (2) transfer pre-defined patterns from the hot stamp to the substrate. Such polished or patterned carbon nanotube substrates can find application as carbon nanotube electrodes, field emitters, and field emitter arrays for displays and electron sources.

摘要： Example computer-implemented methods, computer-readable media, and computer systems are described for providing communication protocol architecture or framework for magnetic induction (MI)-based communications in wireless underground sensor networks (WUSNs), for example, in underground oil reservoirs. In some aspects, environment information of an underground region that affects the transmission qualities of MI communications is evaluated. A protocol stack is identified. The protocol stack includes a number of layers for MI communications among a number of sensors in a WUSN in the underground region. A cross-layer framework and the distributed protocol are built to jointly optimize communication functionalities of the plurality of layers based on the evaluation.
