Abstract:
A method and apparatus for generation of fluorine gas (F2) in situ at the point of use is provided. The portable fluorine generator includes a dilution system disposed within a housing and operable to mix a feed gas comprising fluorine with an inert gas. The portable fluorine generator further includes a plasma reactor unit disposed within the housing and operable to separate fluorine (F2) from the feed gas comprising fluorine.
Abstract:
Described is a doping technique that forms a stable amorphous silicon film and a stable polycrystalline silicon film at a low temperature and simultaneously that imparts conductivity in an atmospheric pressure environment. A method for producing a compound containing a bond between different elements belonging to Group 4 to Group 15 of the periodic table, the method including: applying, at a low frequency and atmospheric pressure, high voltage to an inside of an electric discharge tube obtained by attaching high-voltage electrodes to a metal tube or an insulator tube or between flat plate electrodes while passing an introduction gas, so as to convert molecules present in the electric discharge tube or between the flat plate electrodes into a plasma; and applying the plasma to substances to be irradiated, the substances to be irradiated being two or more elementary substances or compounds.
Abstract:
Materials such as biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) and hydrocarbon-containing materials are processed to produce useful products, such as fuels. For example, systems are described that can use feedstock materials, such as cellulosic and/or lignocellulosic materials and/or starchy materials, or oil sands, oil shale, tar sands, bitumen, and coal to produce altered materials such as fuels (e.g., ethanol and/or butanol). The processing includes exposing the materials to an ion beam.
Abstract:
Organofunctional silicon particles are covalently functionalized on their surface with at least one organic compound, for example a plurality of —O—(C1-C48)-alkyl compounds. The functionalization of the surface of the silicon particles makes it possible to adjust the properties of fluids in terms of their profile of properties by addition of the modified silicon particles. For instance, the alkoxy-functionalized silicon particles may preferably be added to a motor oil as additives for reducing viscosity.
Abstract:
An improved process and for removing NOx from exhaust gases produced by combustion-based energy sources. Catalyst-free exhaust gas is directed into one or more ducts. The gas is cooled and then passes through the duct, wherein the gas flow rate and the electron beam pulse rate are configured to cause each successive volume of gas that flows past the window to be subjected to only a single electron beam pulse in the reaction chamber. A single short, intense electron beam is fired into the exhaust through a window in the reaction chamber as the exhaust flows past the window, with some of the electrons being reflected back into the gas by a reflective plate situated opposite the window. The deposited electron energy causes NOx from the exhaust to be converted into N2 and O2 which are output into the atmosphere with the thus-scrubbed exhaust.
Abstract:
A method of isolating 99Mo produced using a (n,γ) reaction according to example embodiments may include vaporizing a source compound containing 98Mo and 99Mo. The vaporized source compound may be ionized to form ions containing 98Mo and 99Mo. The ions may be separated to isolate the ions containing 99Mo. The isolated ions containing 99Mo may be collected with a collector. Accordingly, the isolated 99Mo may have a relatively high specific radioactivity and, in turn, may be used to produce the diagnostic radioisotope, 99mTc, through radioactive decay.

Biomass (e.g., plant biomass, animal biomass, and municipal waste biomass) is processed to produce useful products, such as fuels. For example, systems can use feedstock materials, such as cellulosic and/or lignocellulosic materials and/or starchy materials, to produce ethanol and/or butanol, e.g., by fermentation.
