    摘要: Semi-crystalline alumina compositions with framework mesopores are disclosed. The compositions are assembled from inorganic aluminum precursors and nonionic polyethylene oxide surfactants. The new assembly pathway introduces several new concepts to alumina mesostructure synthesis. The application of low-cost, non-toxic and biodegradable surfactants and low cost aluminum reagents as alumina precursors which are inorganic and low solution reaction temperatures, introduces efficient and environmentally clean synthetic techniques to the formation of mesostructures. Recovery of the surfactant can be achieved through solvent extraction where the solvent may be water or ethanol or by calcination.

    摘要: Mesoporous hexagonal, cubic, lamellar, wormhole, or cellular foam aluminosilicates, gallosilicates and titanosilicates derived from protozeolitic seeds using an ionic structure directing agent are described. The silicon and aluminum, gallium or titanium centers in the structures are stable so that the framework of the structure does not collapse when heated in the presence of water or water vapor (steam). The steam stable compositions can be used as catalysts for hydrocarbon conversions, including the fluidized bed catalytic cracking and the hydrocracking of petroleum oils, and other reactions of organic compounds.

    摘要: An amplifier applies a self-adapting voltage to an output terminal. A bias circuit provides a greater bias current in a first external connection condition, in the absence of a pull-up resistance connected to the output terminal, than when such a pull-up resistance is present. The amplifier applies a different voltage to the output terminal in the absence of a pull-up resistance than when such a pull-up resistance is present. The circuit can be used in a portable device for receiving charging current from a battery charger through a connector having a D+ pin for connection to the battery charger and connected to the amplifier output terminal for battery charger detection. The portable device can meet the USB battery charger specification rev. 1.2.
