    摘要： Frequency conversion circuitry has an input node for receiving an input signal at a first frequency and an output node for producing an output signal at a second frequency different from the first frequency. A mixer circuit is responsive to the input signal for producing a signal at the second frequency. A step down impedance transformation circuit is coupled between the input node and an input of the mixer circuit for providing input impedance of the mixer circuit lower than impedance at the input node. An amplifier circuit is coupled between an output of the mixer circuit and the output node for amplifying the signal at the second frequency produced at the output of the mixer circuit. The mixer circuit is configured for providing input impedance of the output amplifier lower than the impedance at the input node.

    摘要： The present invention provides continuous, free-standing metal oxide films and methods for making said films. The methods are able to produce large-area, flexible, thin films having one or more continuous, single-crystalline metal oxide domains. The methods include the steps of forming a surfactant monolayer at the surface of an aqueous solution, wherein the headgroups of the surfactant molecules provide a metal oxide film growth template. When metal ions in the aqueous solution are exposed to the metal oxide film growth template in the presence of hydroxide ions under suitable conditions, a continuous, free-standing metal oxide film can be grown from the film growth template downward into the aqueous solution.

    摘要： A dye-sensitized solar cell including ZnO nanowire arrays grown of a flat substrate for harvesting solar energy is integrated with a piezoelectric nanogenerator for harvesting ultrasonic wave energy. The two energy harvesting approaches work simultaneously or individually and can be integrated in parallel or serial for raising the output current, voltage or power, respectively. A solar cell employs an optical fiber and semiconductor nanowires grown around the fiber. A p-n junction based design, organic-inorganic heterojunction, or a dye-sensitized structure is built at the surfaces of the nanowires. Light entering the fiber from a tip propagates through the fiber until it enters a nanowire where it reaches a photovoltaic element. Light entering the fiber cannot escape until it interacts with a photovoltaic element, thereby increasing the solar conversion efficiency. The fiber can transmit light, while the nanowires around the fibers increase the surface area of light exposure.

    摘要： In a method of making a polymer structure on a substrate a layer of a first polymer, having a horizontal top surface, is applied to a surface of the substrate. An area of the top surface of the polymer is manipulated to create an uneven feature that is plasma etched to remove a first portion from the layer of the first polymer thereby leaving the polymer structure extending therefrom. A light emitting structure includes a conductive substrate from which an elongated nanostructure of a first polymer extends. A second polymer coating is disposed about the nanostructure and includes a second polymer, which includes a material such that a band gap exists between the second polymer coating and the elongated nanostructure. A conductive material coats the second polymer coating. The light emitting structure emits light when a voltage is applied between the conductive substrate and the conductive coating.
