Abstract: An apparatus and a non-vapor-pressure dependent method of chemical vapor deposition of Si based materials using direct injection of liquid hydrosilane(s) are presented. Liquid silane precursor solutions may also include metal, non-metal or metalloid dopants, nanomaterials and solvents. An illustrative apparatus has a precursor solution and carrier gas system, atomizer and deposit head with interior chamber and a hot plate supporting the substrate. Atomized liquid silane precursor solutions and carrier gas moves through a confined reaction zone that may be heated and the aerosol and vapor are deposited on a substrate to form a thin film. The substrate may be heated prior to deposition. The deposited film may be processed further with thermal or laser processing.

Abstract: Novel silicone polymers are provided which possess grafted pendant hydrophilic polyalkylene oxide side chains and, optionally, reactive functional end groups. These features make them well suited for use in chemical, marine, biomedical and industrial applications, particularly those involving surface modifications.
Abstract: An aerosol deposition system that uses a liquid ink, fed directly to an ultrasonic source at or near a nozzle to form an aerosolized ink, which may be transported via a carrier gas to a sheath gas insertion location is presented. The sheath gas may direct or focus the atomized ink through a nozzle. Alternatively, a deposition head may be adapted to the ultrasonic source so that aerosolization of the ink occurs inside the deposition head, where the sheath gas flows around the ultrasonic source, transporting the aerosolized ink through a nozzle and toward a substrate ˜2 mm distant. The substrate may be translated to form features of controlled shape such as lines with widths from ?30 ?m to 100 ?m. Variations of this system may yield systems where a carrier gas is unnecessary, and all aerosolized ink is transported via the sheath gas.
Abstract: A vehicle system includes a plurality of capacitors each forming a portion of a vehicle structure, and a parallel electrical link between a pair of the plurality of capacitors, such that the pair of capacitors act as an aggregate capacitor.

Abstract: The invention provides highly functional epoxy resins that may be used themselves in coating formulations and applications but which may be further functionalized via ring-opening reactions of the epoxy groups yielding derivative resins with other useful functionalities. The highly functional epoxy resins are synthesized from the epoxidation of vegetable or seed oil esters of polyols having 4 or more hydroxyl groups/molecule. In one embodiment, the polyol is sucrose and the vegetable or seed oil is selected from corn oil, castor oil, soybean oil, safflower oil, sunflower oil, linseed oil, tall oil fatty acid, tung oil, vernonia oil, and mixtures thereof. Methods of making of the epoxy resin and each of its derivative resins are disclosed as are coating compositions and coated objects using each of the resins.
