Green Chemistry Derived Nanocomposite of Silver-modified Titania used for Disinfectant

Liu J., Ramirez I., Bashir S., Mernaugh R., Texas A&M University-Kingsville, US

A significant accomplishment of this study centers on developing nanocomposite (NC) materials via green synthesis (GS) techniques for inactivation of prokaryotes like Escherichia coli. The motivations are to: (1) implement fundamental research in nanochemistry for [...]

Characterization of Carbon Nanotube-reinforced Polyethylene Nanocomposite Produced by Cryogenic Ball-milling Process

Terife G., Narh K.A., New Jersey Institute of Technology, US

The morphology of polymer nanocomposite, and the degree of dispersion of the MWCNTs were studied using SEM and light transmission microscopy. Both MWCNT ropes and aggregates were observed; also wetting of the nanotubes by the [...]

Mechanical and Moisture Resistance Performance of Silver Nanoparticle Reinforced Fish Skin Gelatin Films

Harding H., Ludwick A., Samuel T., Young S., Aglan H., Tuskegee University, US

Films from the biodegradable polymer gelatin have been studied for biomedical applications not only because of the film forming properties of gelatin, but also because of the availability and economical advantages of gelatin. In this [...]

Directing cell migration by electrospun fibers

Liu Y., State University of New York at Stony Brook, US

We would like to submit the abstract “directing cell migration by electrospun fiber” for the presentation in Nanotech conference 2010. We investigate the influence of substrate on cell migration. We show that it is possible [...]

ZnO:Polydiacetylene Films as Chromatic Sensors

Patlolla A., Zunino III J.L., Schmidt D.P., Iqbal Z., Skelton D.R., U.S. Army, US

Films of the conjugated polydiacetylenes (PDAs) can function as chromatic temperature, chemical and stress sensors, and can be prepared by spin-coating from monomer solutions followed by polymerization. The polymer backbone of PDAs is comprised of [...]

Synthesis and Application of nano-size polymer colloids at The Dow Chemical Company

Tucker C.J., The Dow Chemical Company, US

Over the last 50+ years The Dow Chemical Company has sponsored numerous research programs involving the preparation and use of nano-size colloidal systems. The nano-colloids used range from soft (liquid microemulsions) to solid (polymeric) materials [...]

Effect of Bimodal Micro-Nano Powder Mixture on the Solids Loading and Pressureless Sintering of Silicon Carbide and Aluminum Nitride

Onbattuvelli V., Purdy G., Ramamoothi S., Atre S.V., Oregon State University, US

Solids loading of around 65 vol.% (against the reported 50 vol.%) and 70 vol.% (against the reported 56 vol.%) were achieved for SiC and AlN feedstocks using bimodal micro-nano (μ/n) powder mixtures, respectively. The injection [...]

The physical properties of zein nanoclay hybrid resin as a base for zein nanoclay films

Luecha J., Sozer N., Kokini J.L., University of Illinois at Urbana-Champaign, US

The waste of petroleum-based packaging materials has become the worldwide major environmental concern. Therefore, the biodegradable materials derived from renewable resources have become under spot light as a potential approach to reduce the packaging material [...]

Carbon Nanocomposite Electrode for Electrostatic Precipitators

Alam K., Morosko J., Burton D., Ohio University, US

The electrostatic precipitator (ESP) is a key pollution control component in air pollution control devices for oil and coal-fired industrial boilers. Within the electrostatic precipitator, fly ash particles are charged electrically due to a corona [...]

Wide Area Deposition of Transparent Flexible Nanocomposites

Druffel T., Optical Dynamics, US

Our group has been involved in the deposition of thin film nanocomposites via spin coating in which the optical and mechanical properties of the composites is controlled by the volume packing of the inorganic nanoparticles. [...]
