  • Patent number: 8652632
    Abstract: Disclosed herein is a structure having a spatially organized polymer nanostructured thin film and a metal coating on the film. The thin film is made by directing a monomer vapor or pyrolyzed monomer vapor towards a substrate at an angle other than perpendicular to the substrate, and polymerizing the monomer or pyrolyzed monomer on the substrate.
    Type: Grant
    Filed: June 3, 2009
    Date of Patent: February 18, 2014
    Assignee: The United States of America, as represented by the Secretary of the Navy
    Inventors: Melik C. Demirel, Walter J. Dressick, David Allara

  • Publication number: 20080279754
    Abstract: In the apparatus and process of the present invention, it is possible to fabricate CNTs with specific diameters and morphologies. The morphology selection can yield samples of pre-selected diameter configurations making it possible to take a sample of SWNTs produced by any synthesis technique and induce a morphology change that causes the sample to be either all conductive, all narrow band gap semiconductive or wide band gap semiconductive, within a given nanotube rope.

  • Publication number: 20070297216
    Abstract: A method for selectively assembling a molecular device on a substrate comprises contacting the first substrate with a solution containing molecular devices; impeding bonding of the molecular devices to the substrate such that application of a voltage potential to the substrate results in assembly of the molecular device on the substrate at a rate that is at least 1.5 times the rate of assembly of the molecular device on a voltage-neutral substrate; and applying a voltage potential to the substrate so as to cause the molecular devices to assemble on the substrate. A nanoscale computing device is described that includes a substrate, a pair of conductive input/output electrodes carried on this substrate and disposed in spaced-apart relationship and a substantially disordered assembly of nanowires formed on the substrate in a region between the electrodes, thereby forming at least one programmable conductive pathway between the pair of electrodes.

  • Publication number: 20060061762
    Abstract: An improved substrate for Raman spectroscopy of an analyte comprises a porous metal film. Enhancement factors and uniformity of the substrate can be enhanced by electrochemical roughening of the film. Improved sensors and spectrometers using such substrates are also described.

  • Publication number: 20050175885
    Abstract: What is disclosed is a process and apparatus for subjecting carbon nanotubes (100), to EM radiation for certain predetermined amounts of time. The result of said process and apparatus is heat release, light emission and gas evolution, accompanied by intense mechanical motion and carbon nanotube reconstruction.

  • Publication number: 20050118092
    Abstract: An apparatus and process for fabricating carbon nanotubes (“CNTs”) with specific diameters and morphologies, comprising a vacuum system, CNT holder and microwave source adapted for directing a microwave field onto the CNTs. The morphology selection can yield samples of pre-selected diameter configurations making it possible to take a sample of SWNTs produced by any synthesis technique and induce a morphology change that causes the sample to be either all conductive, all narrow band gap semi-conductive or wide band gap semi-conductive, within a given nanotube rope.

  • Publication number: 20050007001
    Abstract: The present invention provides a process and apparatus to store and deliver controlled amounts of heat and light energy, from low levels to very intense levels, to microscopic locations in a object remotely, not necessarily involving direct contact with the object, where the energy delivered remotely is less than the energy released by the object. More specifically, the present invention comprises a novel and previously unanticipated source of local energy production by the exposure of carbon nanotubes by EM radiation in the radio and microwave spectral regions. The present invention comprising a process and apparatus to remotely delivering highly controlled amounts of EM to the carbon nanotubes.
