Abstract: This invention provides a better means to achieve affordable solar energy, as well as other technologies. It does so by improving control grids (for addressing and alignment) in solar concentrators and optical equipment in general. Thus troublesome and expensive grid material like Indium Tin Oxide (ITO) can be replaced by more manageable, hardier, and in the long run relatively less expensive nanotubes; or a carbon grid simply laid down by ordinary photocopy (Xerographic) reduction techniques. The instant invention relates to improvements in the control (addressing and alignment) grid for Solar Energy Concentrators; and similar equipment such as Optical Switches [e.g. cf. M. Rabinowitz U.S. Pat. No. 6,976,445]; and Display devices such as Dynamic Reflection, Illumination, and Projection equipment [e.g. cf. M. Rabinowitz U.S. Pat. No. 7,130,102]; as well as display equipment in general.

Abstract: The present invention discloses a mold and a method of manufacturing the mold. The mold includes a mold matrix and a number of boron nitride nanotubes sintered together with the mold matrix. Each boron nitride nanotube capsules a number of fullerenes therein respectively.

Abstract: A method of simultaneously fabricating at least two semiconductor devices, at least bone of which is a nanocrystal memory and at least one of which is a non-nanocrystal semiconductor device. A nanocrystal layer is formed over an oxide layer of the at least two semiconductor devices being fabricated. The nanocrystal layer is removed from at least one portion of the substrate corresponding to the at least one non-nanocrystal device being fabricated. A polycrystalline gate is formed for each of the semiconductor devices being fabricated. Doping is provided to provide the source and drain regions for each of the semiconductor devices being fabricated. The substrate is thermally treated after the doping. The thermal budget of the fabrication process is not limited by this thermal treatment.
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: A solid state nanopore device including two or more materials and a method for fabricating the same. The device includes a solid state insulating membrane having an exposed surface, a conductive material disposed on at least a portion of the exposed surface of the solid state membrane, and a nanopore penetrating an area of the conductive material and at least a portion of the solid state membrane.

When the surface is exposed to an ion beam, material from the membrane and conductive material flows to reduce the diameter of the nanopore. A method for evaluating a polymer molecule using the solid state nanopore device is also described. The device is contacted with the polymer molecule and the molecule is passed through the nanopore, allowing each monomer of the polymer molecule to be monitored.
