20100295019 | NANOWIRE PHOTODETECTOR AND IMAGE SENSOR WITH INTERNAL GAIN - A practical ID nanowire photodetector with high gain that can be controlled by a radial electric field established in the ID nanowire. A ID nanowire photodetector device of the invention includes a nanowire that is individually contacted by electrodes for applying a longitudinal electric field which drives the photocurrent. An intrinsic radial electric field to the nanowire inhibits photo-carrier recombination, thus enhancing the photocurrent response. The invention further provides circuits of ID nanowire photodetectors, with groups of photodetectors addressed by their individual ID nanowires electrode contacts. The invention also provides a method for placement of ID nanostructures, including nanowires, with registration onto a substrate. A substrate is patterned with a material, e.g., photoresist, and trenches are formed in the patterning material at predetermined locations for the placement of ID nanostructures. The ID nanostructures are aligned in a liquid suspension, and then transferred into the trenches from the liquid suspension. Removal of the patterning material places the ID nanostructures in predetermined, registered positions on the substrate. | 11-25-2010 |
20110163292 | Nanowire Array-Based Light Emitting Diodes and Lasers - Semiconductor nanowire arrays are used to replace the conventional planar layered construction for fabrication of LEDs and laser diodes. The nanowire arrays are formed from III-V or II-VI compound semiconductors on a conducting substrate. For fabrication of the device, an electrode layer is deposited on the substrate, a core material of one of a p-type and n-type compound semiconductor material is formed on top of the electrode as a planar base with a plurality of nanowires extending substantially vertically therefrom. A shell material of the other of the p-type and n-type compound semiconductor material is formed over an outer surface of the core material so that a p-n junction is formed across the planar base and over each of the plurality of nanowires. An electrode coating is formed an outer surface of the shell material for providing electrical contact to a current source. Heterostructures and superlattices grown along the lengths of the nanowires allow the confinement of photons in the quantum well to enhance the efficiency and as well as color tuning. | 07-07-2011 |

20140103295 | NANOWIRE PHOTODETECTOR AND IMAGE SENSOR WITH INTERNAL GAIN - A 1D nanowire photodetector device includes a nanowire that is individually contacted by electrodes for applying a longitudinal electric field which drives the photocurrent. An intrinsic radial electric field to inhibits photo-carrier recombination, thus enhancing the photocurrent response. Circuits of 1D nanowire photodetectors include groups of photodetectors addressed by their individual 1D nanowire electrode contacts. Placement of 1D nanostructures is accomplished with registration onto a substrate. A substrate is patterned with a material, e.g., photoresist, and trenches are formed in the patterning material at predetermined locations for the placement of 1D nanostructures. The 1D nanostructures are aligned in a liquid suspension, and then transferred into the trenches from the liquid suspension. Removal of the patterning material places the 1D nanostructures in predetermined, registered positions on the substrate. | 04-17-2014 |

20100081762 | Brominated Styrenic Polymers and Their Preparation - Preparing brominated styrenic polymer by maintaining a mixture formed from (i) brominating agent, (ii) a solvent solution of styrenic polymer, and (iii) aluminum halide catalyst, at −20 to +20° C., and terminating bromination in 20 minutes or less. New brominated anionic styrenic polymers have better melt flow and/or lower initial ΔE values than the best previously-known brominated anionic styrenic polymers. Other features of such new polymers include high thermal stabilities at 320° C. and/or very low initial color values. Brominated styrenic polymers, especially brominated anionic styrenic polymers, are useful as flame retardants for thermoplastic polymers. | 04-01-2010 |

20110296700 | Straight edge circle tool - The tool is formed of an elongate rigid bar having a pair of straight side edges extending between opposite ends. Indicia are provided adjacent graduations correlating with distances away from center holes located at each end of the bar. A series of marking holes are provided at various distances away from the center holes. Thus, when a pin is provided through one center hole, a marking tool can be placed within a marking hole having a distance corresponding with a radius of a curve to be formed, and the bar can be rotated about the pin in the center hole while the marker is allowed to form a mark in an underlying workpiece. The straight edges of the tool can also be utilized for forming straight edges. | 12-08-2011 |

20120079767 | FUEL FROM SEPARATE HYDROGEN AND CARBON MONOXIDE FEEDS - A process and system for producing synthesis gas (syngas) by combining hydrogen and carbon monoxide from separate sources while controlling the mole ratio (H2/CO) of the syngas product. Hydrogen is produced by splitting water. Carbon monoxide is produced by reacting carbon dioxide (CO2), which has been captured from the exhaust of stationary combustion engines, with hydrogen via the Reverse Water Gas Shift. Hydrocarbon fuels are produced from this syngas via the Fischer-Tropsch synthesis. | 04-05-2012 |
