Synthesizing a nanocomposite tungsten carbide-cobalt metal oxide

Al-Hazza A.A., Kuwait Institute for Scientific Research, KW

In this work a nanocomposite WC-Co metal oxide was synthesized by using a solid state mixing techniques. Certain metals oxide were used in this process (Al, Mg, Si, and Zr) to enhance the property of [...]

Highly Tunable Surface Plasmons Resonance Using Metal/metal Oxide Hybrid Nanostructures

Khosroabadi A.A., Gangopadhyay P., Norwood R.A., University of Arizona, US

Metal and metal oxide electrodes play a significant role in many cutting edge applications including photonics, membranes, biological supports, sensing, electrochromics, and in various green technologies, such as, photocatalytics, Li-ion batteries and photovoltaics. There is [...]

Surface Chemistry of Metal Oxide Nanoparticles and Attachment of Metal Nanoclusters: Sensor, Optoelectronic, and Catalytic Applications

Whitten J.E., University of Massachusetts-Lowell, US

Metal oxide nanoparticles are surprisingly reactive, and some undergo changes in color or in their photoluminescence (PL) spectra upon reaction. In the latter case, visible emission arises from electron decay from surface related states, and [...]

Synthesis and characterization of (polypyrrole/carbon) nanotubes/metal oxide composites for application as supercapacitors

de Oliveira A.H.P., de Oliveira H.P., de Oliveira A.H.P., de Oliveira H.P., UNIVASF, BR

The development of eco-friendly technologies such as hybrid vehicles requires more efficient high power energy storage materials, viz. supercapacitors. As reported in our previous work, the association of polypyrrole and carbon derivatives (modified graphene oxide [...]

Crystal-like growth of metal oxide/CNT composite with electroplated “seed”

Kim W-J, Kim Y.H., Jang E.Y., Seo D.K., Kang T.J., Jin K.C., Jeong D.H., Kim W-J, Kim Y.H., Seoul National University, KR

In this study, we developed a novel assembly technique for macroscopic one-dimensional metal oxide/CNT composites. An essential feature of the technique lies in the use of non-aqueous electrolyte in place of the usual aqueous electrolyte [...]

Fabrication of superhydrophobic nanostructured films by Physical Vapour Deposition

Yoldi M., García J.A., Rodríguez R.J., Rico M., AIN, ES

This work reports on recent advances in the deposition of non-wettable coatings with high water contact angles (WCAs). We propose a simple and easily-controlled method for fabricating different types of nanoestructured films with hydrophobic properties [...]

Biodistribution and Toxicity of Nanomaterials In Vivo: Effects of Composition, Size, Surface Functionalization and Route of Exposure

Harper S.L., Maddux B., Hutchison J., Tanguay R.L., Oregon State University, US

Given the anticipated growth of the nanotechnology industry and the deficiency of toxicological information, there is an obvious need for rapid, relevant and efficient testing strategies to evaluate the biological activity and toxic potential of [...]
