Mass Production of Metal Oxide Nanoparticle Dispersion for Heat-ray Shielding Application

Shen Z., Soh W., Zhang J., Wang A., Chen J., Chen W., Yun J., Sher D., Chen J., Chen W., NanoMaterials Technology Pte Ltd, SG

A unified approach, HGCP process was applied to produce various metal oxide nanoparticle dispersion with low cost. The process involved achieving instantaneous molecular mixing for metal salts and precipitant reactants by using HGCP reactor to [...]

Effects of Silicon Nanowires on HepG2 Cell Adhesion and Spreading

Qi S., Yi C., Chen W., Fong C-C, Lee S-T, Yang M., City University of Hong Kong, CN

The unique capabilities of nanomaterials make them good candidates for catalysts, biosensors, and even drug carriers. However, interactions of nanomaterials with biological systems and the environment may lead to potential toxicity. While there have been [...]

Nanowire Sensors and Arrays for Chemical/Biomolecule Detection

Yun M., Lee C., Vasquez R.P., Ramanathan K., Bangar M.A., Chen W., Mulchandan A., Myung N.V., Jet Propulsion Laboratory, US

We report electrochemical growth of nanowire sensors using e-beam patterned electrolyte channels, potentially enabling the controlled fabrication of individually addressable arrays. The electrodeposition technique results in nanowires with controlled dimensions, positions, alignments, and chemical compositions. [...]

Alignment Characteristic and Mechanism of Carbon Nanotubes Synthesized by Hot Filament Chemical Vapor Deposition in a CH4/H2 Plasma

Yang Q., Chen W., Singh A., Xiao C., Hirose A., University of Saskatchewan, CA

Controlling of the alignment of carbon nanotubes (CNTs) is very important for applications such as scanning probes, sensors, field emitters and nanoelectronics. Controlled growth of CNTs aligned at different angles to the substrate has been [...]
