    摘要： Methods and apparatus for the preparation of nitrogen fertilizers including ammonium nitrate, urea, urea-ammonium nitrate, and/or ammonia, at low temperature and pressure, preferably at ambient temperature and pressure, utilizing a source of carbon, a source of nitrogen, and/or a source of hydrogen or hydrogen equivalent. Implementing an electrolyte serving as ionic charge carrier, (1) ammonium nitrate is produced via the reduction of a nitrogen source at the cathode and the oxidation of a nitrogen source at the anode; (2) urea or its isomers are produced via the simultaneous cathodic reduction of a carbon source and a nitrogen source; (3) ammonia is produced via the reduction of nitrogen source at the cathode and the oxidation of a hydrogen source or a hydrogen equivalent such as carbon monoxide or a mixture of carbon monoxide and hydrogen at the anode; and (4) urea-ammonium nitrate is produced via the simultaneous cathodic reduction of a carbon source and a nitrogen source, and anodic oxidation of a nitrogen source. The electrolyte can be aqueous, non-aqueous, or solid. Additionally, described is the production of ammonia from nitrogen and impure hydrogen sources via integrated electrochemical and thermal reactions and electrochemical hydrogen purification.

    摘要： A closed loop energy storage system configured with a hydrogen tank, an oxygen tank, a fuel cell stack and an electrolyzer. A heat exchanger freeze-dries the hydrogen and oxygen prior to their storage in their respective tanks. The heat exchanger also uses excess fuel cell heat to preheat streams of hydrogen and oxygen coming from the tanks. Phase separators serve both to separate water from hydrogen and oxygen, and to store the water. A thermal management system encloses all the system components except the tanks. An airfoil-shaped shell covers the system, and the larger of the two tanks extends substantially across the shell at its point of greatest camber thickness. The tanks are composed of polymer liners integral with composite shells.

    摘要： Titania is a semiconductor and photocatalyst that is also chemically inert. With its bandgap of 3.0, to activate the photocatalytic property of titania requires light of about 390 nm wavelength, which is in the ultra-violet, where sunlight is very low in intensity. A method and devices are disclosed wherein stress is induced and managed in a thin film of titania in order to shift and lower the bandgap energy into the longer wavelengths that are more abundant in sunlight. Applications of this stress-induced bandgap-shifted titania photocatalytic surface include photoelectrolysis for production of hydrogen gas from water, photovoltaics for production of electricity, and photocatalysis for detoxification and disinfection.

    摘要： Continuous nanotube synthesis by vortex deposition occurs in an axially-fed shear reactor comprising coaxial counter-rotating disk impeller/electrodes charged as anodes. Nanotube evolving ends, charged as cathodes, point toward the anode axis of rotation and protrude into the space between the anodes. Radial vortices in a shear layer of the space, between the boundary layers on the impeller/electrodes, spin cations to be deposited on evolving nanotube ends approximately at the vortex axis, so deposition is by swirling cathode fall. The evolved nanotubes are extracted mechanically, and they conduct electrons from charging means to charge the evolving ends as cathodes. The preferential synthesis of metallic carbon nanotubes is due to the greater resistance of non-metallic structures such as graphite or semiconductive structures. Ozone serves to oxidize non-metallic structures and to functionalize the loose ends of nanotube fragments. Dopants can be added to the evolving nanotubes by introduction of dopants at the periphery because the evolving ends are maintained in stable locations. Or dopants can be added by the simultaneous decomposition of gases (for example, carbon dioxide and nitrogen gas) within the reactor or in an external reactor.

    摘要： A photolysis-assisted electrolysis device comprises at least one fluidized bed disposed in the device's housing wherein the fluidized bed comprises a reaction medium and photolysis-catalyzing nanoparticles suspended in the reaction medium. When the fluidized bed is exposed to light, the nanoparticles catalyze the photolysis of the reaction medium to form donor electrons. The donor electrons promote reduction of the reaction medium during an electrolysis reaction, for example, the reduction of water to form hydrogen gas.
