Dye-sensitized solar cell using a TiO2 nanocrystalline film electrode prepared by solution combustion synthesis

Wang C.M., Chungb S.L., National Cheng Kung University, TW

The nanocrystalline anatase TiO2 films were prepared and characterized in connection with their application to dye-sensitized solar cells. Solution combustion synthesis of TiO2 nanocrystalline film is based on hydrolysis, nitrated, and combustion reaction. The solution [...]

Aided Transport of Nano-Iron in Clay Soils Using Direct Electric Field

Hannum L., Pamukcu S., Lehigh University, US

The influence of direct current electric fields on the possible electrokinetic delivery of a nano-iron slurry in clay for the purpose of fast and effective remediation of soil contaminants has been tested. Nano-iron can be [...]

Ultra-short pulsed laser for nano-texturation associated to plasma immersion implantation for 3D shallow doping : Application to silicon photovoltaic

Halbwax M., Sarnet T., Delaporte Ph., Sentis M., Etienne H., Torregrosa F., Vervisch V., Martinuzzi S., LP3 UMR CNRS 6182, FR

It has been shown in a recent past (Mazur et al) that a simple way to improve the silicon-based solar cells low efficiency (around 20%) is to irradiate the silicon surface with a series of [...]

An investigation of natural nanoparticles for cleaning applications

Nero M., Tran B., Naturell Clean, Inc., US

Bioremediant cleaning products are investigated for every day use by consumers in their homes. Nano-components such as biosurfactants, enzymes, metaloenzymes, and chelating agents are derived from Sea Kelp and are the result of naturally occurring [...]

Amorphous Diamond as a Thermionic Material

Sung J.C., Sung M., Kan M-C, Hsiao T-J., Chen Y-T, Sung J.C., Sung M., Kinik Company, TW

Amorphous diamond is essentially a chaotic carbon mixture with distorted sp2 and sp3 bonds. As such it possesses both metallic character of conductive graphite and semiconductor character of insulating diamond. Moreover, as each carbon atom [...]

Theoretical Study of the Reaction between OH Radicals and Formaldehyde adsorbed on Small Silica Clusters

Iuga C., Vivier-Bunge A., Universidad Autónoma Metropolitana, MX

Heterogeneous reactions of atmospheric gases on aerosol particles may play an important role in atmospheric chemistry. However, the kinetics and mechanisms of adsorption and reaction of atmospheric gases on aerosol surfaces are not well understood. [...]

Preparation and Characterization of Nafion/Microporous Titanosilicate Composite Membranes as Ion-Conducting Materials

Ryu S.-Y., Jeon J-D, Kwak S-Y, Seoul National Univesity, KR

Nafion is currently the most frequently used polymeric electrolyte in membranes for many fuel cell applications. Direct methanol fuel cells this electrolyte membrane are currently being considered as a desirable electrochemical power source in potable [...]

Characterization on Dioxin Emission of TiO2 Nanoparticle-Encapsulating Poly(vinyl chloride) (TEPVC) compared to conventional PVC

Yoo H., Kim S-H, Lee A.R., Kwak S-Y, Seoul National University, KR

In our previous study, we first prepared TiO2 nanoparticle-encapsulating poly(vinyl chloride) (TEPVC) aiming at breakthrough to enhance the dispersibility of TiO2 nanoparticles in PVC matrix to maximize catalytic activities of TiO2 nanoparticles. The present study [...]

Multifunctional Bio-Nano Patterns Derived from Colloidal Self-Assembly as Model Surfaces to Study Antigen-Antibody Interactions

Krishnamoorthy S., Wright J.P., Worsfold O., Fujii T., Himmelhaus M., Fujirebio Inc., JP

Nanosphere lithography (NSL) has become a popular tool as a patterning technique recently because the method is cheap and involves extremely simple procedures compared with other nanopatterning techniques. NSL can also be applied to a [...]

Nano-Patterned Surfaces Enhance Immunoreaction Efficiency

Valsesia A., Mannelli I., Colpo P., Bretagnol F., Ceccone G., Rossi F., European Commision Joint researcc Center, IT

Biomolecular recognition is a fundamental aspect in the biosensor development. The goal is to immobilize the biomolecule probes in an active state, limiting the non specific adsorption and maximizing their binding site accessibility for the [...]
