    Abstract: An effective sensor for indicating exposure to a toxic gas includes a non-conductive, inert substrate such as glass or polyethylene, a two-dimensional film of nanoparticles of a conductive metal such as silver or copper on the substrate and an electrode connected to each end of the film. When an electrical current passes through the film and the sensor is exposed to a toxic gas, changes in the electrical resistance of the film provides an indication of the presence of the toxic gas.

  • Publication number: 20100255320
    Abstract: A method for forming a conductive elastomer by applying or spray coating a conductive paste onto an elastomeric substrate using a reactive top coat to thin the conductive paste prior to spraying onto the substrate. The use of a reactive topcoat to thin the conductive paste avoids the need for hazardous volatile organic components as solvents to thin the conduct paste and improves the bonding of the conductive paste to the elastomeric substrate once the spray coating is cured.

    Abstract: High-surface-area carbon nanostructures coated with a smooth and conformal submonolayer-to-multilayer thin metal films and their method of manufacture are described. The preferred manufacturing process involves the initial oxidation of the carbon nanostructures followed by immersion in a solution with the desired pH to create negative surface dipoles. The nanostructures are subsequently immersed in an alkaline solution containing non-noble metal ions which adsorb at surface reaction sites. The metal ions are then reduced via chemical or electrical means and the nanostructures are exposed to a solution containing a salt of one or more noble metals which replace adsorbed non-noble surface metal atoms by galvanic displacement. Subsequent film growth may be performed via the initial quasi-underpotential deposition of a non-noble metal followed by immersion in a solution comprising a more noble metal.

  • Publication number: 20090274834
    Abstract: A method of forming conductive features on a substrate from a solution of metal nanoparticles by providing a depositing solution and liquid depositing the depositing solution onto a substrate. The depositing solution is then heated to a temperature below about 140° C. to anneal the first and second nanoparticles and remove any reaction by-products. The depositing solution may be comprised of a mixture of first metal nanoparticles and second metal nanoparticles or a combination of first metal nanoparticles and a soluble second metal nanopartical precursor. Furthermore, the average diameter of the first metal nanoparticles is about 50 nm to about 100 ?m and the average diameter of the second metal nanoparticles is about 0.5 nm to about 20 nm.

  • Publication number: 20090262412
    Abstract: Embodiments of the present disclosure include a method of fabricating interferometric devices using lift-off processing techniques. Use of lift-off processing in the fabrication of various layers of interferometric modulators, such as an optical stack or a flex layer, advantageously avoids individualized chemistries associated with the plurality of materials associated with each layer thereof. Moreover, use of lift-off processing allows much greater selection in both materials and facilities available for fabrication of interferometric modulators.

  • Publication number: 20090252938
    Abstract: Provided are a substrate structure and method of forming the same. The method of forming the substrate structure may include etching a substrate to form an etched portion having a vertical surface, forming a diffusion material layer on the whole substrate or in part of the substrate; annealing the diffusion material layer to form a seed layer diffused downward toward the surface of the etched portion, and forming a metal layer on the seed layer. Accordingly, surface characteristics of the etched portion of the substrate may be enhanced by the seed layer, and therefore, a metal layer with improved adhesion and a uniform thickness may be formed on the vertical surface of the etched portion.

  • Patent number: 7597769
    Abstract: Provided are silver-containing powders and a method and apparatus for manufacturing the silver-containing particles of high quality, of a small size and narrow size distribution. An aerosol is generated from liquid feed and sent to a furnace, where liquid in droplets in the aerosol is vaporized to permit formation of the desired particles, which are then collected in a particle collector. The aerosol generation involves preparation of a high quality aerosol, with a narrow droplet size distribution, with close control over droplet size and with a high droplet loading suitable for commercial applications.
