Abstract: A battery anode comprised of metallic nanowire arrays is disclosed. In one embodiment the lithium battery uses Silicon nanowires or another element that alloy with Lithium or another element to produce high capacity lithium battery anodes.

Abstract: A battery anode comprised of a coated metallic nanowire array is disclosed. In one embodiment, an array of copper nanowires is attached to a copper substrate and coated with amorphous silicon. The center to center spacing of the nanowires and their diameter and the coating thickness are set so that the silicon coating of neighboring nanowires does not touch or severely inhibit electrolyte flow after the silicon layer has expanded due to charge insertion. In another embodiment, the silicon coating fully covers the nanowires and the nanowires provide structural support that ameliorates stress in the silicon film due to charge cycling.

Abstract: Freestanding metallic nanowires attached to a metallic substrate are disclosed. A method of creating the nanowire structure using an anodized layer is presented. In one embodiment an optical SERS sensor is formed. The sensor head has at least one array of nanowires chemically functionalized to recognize molecules of interest. A method of forming a SERS sensor and using the sensor to analyze a sample is presented.

Abstract: A heat pipe with a nanostructured wick is disclosed, with the method of forming the nanostructured wick on a metal substrate. The wicking material is a pattern of metallic nanostructures in the form of bristles or nanowires attached to a substrate, where the bristles are substantially freestanding.

Abstract: This invention relates to the fabrication of nanowires for electrical and electronic applications. A method of growing silicon nanowires using an alumina template is disclosed whereby the aluminum forming the alumina is also used as the catalyst for growing the silicon nanowires in a VLS (CVD) process and as the semiconductor dopant. In addition, various techniques for masking off parts of the aluminum and alumina in order to maintain electrical isolation between device layers is disclosed.

Abstract: A photovoltaic wire is presented where the active layers coat a metallic wire, preferably aluminum. The active layers are an array of doped silicon nanowires electrically attached to the metallic wire that extend from the surface of the wire into a layer of semiconducting polymer, preferably polyaniline. The surface of the polymer is coated with a transparent conductor to complete the photovoltaic circuit.
