Fabrication of CuO Nanofilm preparation by Electrophoretic Deposition

Chang H., Wei C.H., National Taipei University of Technology, TW

This paper uses electrophoretic deposition for coating a self-fabricated CuO nanofluid on a stainless steel substrate and measures the nature of this nanofilm. The pH value of the fabricated CuO nanofluid is 6.0, with a [...]

Comparison of Heat Transfer and Fluid Dynamic Performance of Nanofluids

Kulkarni D.P., Namburu P.K., Das D.K., University of Alaska Fairbanks, US

Many recent studies have shown that nanofluids with metallic nanoparticles as suspension increase the thermal conductivity of base fluid by a substantial amount. Research on copper oxide (CuO) nanoparticles in water has revealed that a [...]

Nonlinear Optical Property of Gold nanoparticles/Polymer Hybrid Materials

Dai Q., Zou J., Huo Q., Nanoscience Technology Center, University of Central Florida, US

The ability to control the assembly of nanoparticle building blocks is very important in the development of new nanostructured materials and devices. It is well known that the properties of nanostructured materials are not only [...]

Synthesis of Water Soluble Gold Nanoparticles and Adsorption of Dyes onto Gold Nanoparticles

Narband N., Parkin I., Wilson M., Gil Thomas J., University College London, UK

The synthesis of gold nanoparticles was performed by the Turkevich method. The effect of adding various dyes to gold hydrosols was investigated. It was found that the U. V. absorption characteristics of the dyes change [...]

Reversible Formation of Silver Nanoparticles in Poly(vinyl alcohol)-Based Thin Films via Electrochemical Switching

Black J.R., Cammaratta V., Gaddy G.A., Slaten B.L., Mills G., Auburn University, US

Ag particles with nanometer dimensions were generated reversibly in the presence of air within micron-thick polymer films using electrochemical techniques.

New process for fabrication of microcomponents using metal nanopowder

Lee H.M., Choi C-J, Korea Institute of Machinery and Materials, KR

We developed a new process to manufacture a soft mould for the small parts using two kinds of polymer, SU-8 for a master mould and Polydimethylsiloxane (PDMS) for a soft mould and produced the small [...]

Direct Laser Writing of Microtunnels and Reservoirs on Nanocomposite Materials

Chen H., Liu X., Muthuraman H., Zou J., Wang J., Dai Q., Huo Q., University of Central Florida, US

Using the efficient photon—thermal energy conversion property of gold nanoparticles, a direct laser writing method has been developed for the fabrication of microstructures including microtunnels (see figure), holes, and reservoirs on nanoparticle/polymer composite thin films. [...]
