Catalyst assisted zinc oxide nanowires for gas sensors

Joshi R.K., Kumar A., University of South Florida, US

We present the room temperature detection of 100 ppm carbon monoxide using metal ( Pd and Au) decorated Zinc Oxide (ZnO) nanowires. Zin oxide nanowires were grown via Vapor Liquid Solid method whreas the palladium [...]

Strain Driven Growth of Zinc Oxide Nanowires on Sapphire: Controlling Horizontal vs. Standing Growth

Nikoobakht B., Eustis S., National Institute of Standards and Technology, US

Recently we showed large scale fabrication of field-effect transistors from horizontal ZnO nanowires (NWs) on a-plane sapphire. We are interested in understanding the factors that induce the unique growth direction of horizontal ZnO NWs and [...]

Synthesis of Self-aligned Tungsten Nanowires on Single Crystalline Tungsten Substrates

Wu W., Yu Q., Pei S-S, University of Houston, US

Metallic nanowires have attracted much attention due to their unique mechanical, magnetic, optical and electronic properties, and their function as well-defined building blocks for nanodevices.1-3 Tungsten (W), in particular, is of great interest, being promising [...]

Aluminium-Doped ZnO Films and Nanowires by a Modified Chemical Vapor Deposition Technique

Pung S.Y., Choy K.L., University of Nottingham, UK

ZnO has unique properties such as wide-bandgap (3.37eV) and large exciton binding energy (60meV) at room temperature. These properties made ZnO a promising material for short wavelength photonic devices for examples, light emitting diode (LED) [...]

A Line Force Model to Measure the Strength of Polydimethylsiloxane (PDMS)-to-PDMS Bonding in Blister Tests

Lin P-T, Lu Y-W, Rutgers University, US

Bonding is an important technique in microelectronics and Microelectromechanical Systems (MEMS). Especially, bonding two pieces of polydimethylsiloxane (PDMS) to make micro devices was widely used in micro actuators and BioMEMS. The PDMS bonding, however, lacked [...]

Effects of interface on the physical properties of nanoparticle-filled composites

Jang K.H., Kim B.C., Hanyang University, KR

The effects of interface affinity on the rheological responses of nanoparticle suspended polymer solutions were investigated. The polarity on rheological properties of zinc oxide (ZnO) nanoparticle filled-polymer solution was investigated for polyacrylonitrile (PAN) and polystyrene [...]

Efects of silver nanoparticle on the physical properties of syndiotactic polypropylene

Kang E.C., Kim B.C., Hanyang University, KR

The effects of silver nanoparticle on the physical properties of syndiotactic polypropylene (sPP) were investigated in terms of rheological responses and crystallization behavior under shear. Silver nanoparticle played as the nucleating agent of sPP by [...]

Controlled Surfaces and Novel Polymers for Personal Care: Self-Assembly of Polymers and Surface Modification

Mowers W.A., Berg M.C., Suddaby N., Bercovici D., Soane D., Soane Labs / Cosmetica, US

Cosmetica develops and applies nanotechnology and advanced polymer chemistry to create novel products for the cosmetic industry. We achieve this goal by controlling the spontaneous self-assembly of polymers or colorants at surfaces. Current research projects [...]

Surface modification of Cp-Titanium by Plasma polymerization of acrylic acid

Park H.J., Park S-J, Cho D.L., Park H.J., Park S-J, Ko Y.M., College of Dentistry, 2nd stage of brain korea 21, Chosun University, KR

Cp titanium sheet (15 mm x 15 mm) was used to two different surface treatments, including, etching with an HCl/H2SO4 solution and non-treated bare Ti sheet. To improve the adhesive strength of AA films, we [...]
