Nanotechnology – Disruptive Technologies for Electric Utility Systems. Challenges and Opportunities.

Stringer J., Richman R.H., Izambard, US

Within the next 25 years, the electric power utility system in the U.S. will face a number of serious challenges. These will include issues related to diminishing supplies and increasing costs of fossil fuels, the [...]

TiO2:Mn nanoparticles as enhanced UVA absorption, photostable sunscreen components

Duggan A., Wakefield G., Oxonica Materials Ltd, UK

Conventional sunscreen formulations typically contain, in addition to organic UV absorbers, inorganic nanoparticles such as titanium oxide or zinc oxide. Titanium oxide nanoparticles have significant drawbacks due to a high photoactivity which results in degradation [...]

Nano-Hetero Structure for direct energy conversion

Popa-Simil L., LAVM, Inc., US

The direct conversion of nuclear energy becomes possible in hetero-nanostructures. To convert the kinetic energy of the fission product into electricity it has to be created a nanostructure formed from a repetitive conductor-insulator structure generically [...]

Mono-component Silicone based Conformal Coating

Francès J.-M., Hantin V., Schneider S., RHODIA SILICONES, FR

We will present a UV resin designed to protect printed circuit board. The UV resin is cured by cationic polymerisation and present high performances with advantages such as low viscosity, no need of inertisation during [...]

Synthesis and characterization of a highly cross linked PEGME and PEG for solid electrolyte and its application in dye-sensitized solar cells

Shaheer Akhtar M., Chun J-M, Lee H-C, Kim K-J, Yang O-B, Chnonbuk National University, KR

The replacement of liquid electrolyte in dye sensitized solar cells by gel and solid electrolyte is one approach towards the improvement of properties of electrolyte such as leakage and evaporation of liquid to operate for [...]

Synthesis and characterisation of flame-sprayed superparamagnetic bare and silica-coated maghemite nanoparticles

Teoh W.Y., Li D., Selomulya C., Woodward R., Amal R., Monash University, AU

Magnetic nanoparticles are a much sought-after entity with direct applications in bioseparation, magnetic resonance imaging (MRI), drug delivery and cancer therapy. gamma-Fe2O3 and SiO2/ gamma-Fe2O3 nanoparticles of different sizes (dBET = 5-50 nm) were synthesised [...]

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 [...]

Two-nozzle flame synthesis of tailored Pt/Ba/Al2O3 nanoparticles for NOx storage-reduction

Strobel R., Piacentini M., Maciejewski M., Baiker A., Pratsinis S.E., ETH Zürich, CH

NOx storage reduction (NSR) catalysts are applied for the abatement of NOx from engines operating under lean conditions, where conventional TWC catalysts are inefficient. Here, a novel two-nozzle flame spray pyrolysis (FSP) process was developed [...]

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 [...]

Measuring Nanoparticle Size Distributions in Real-Time: Key Factors for Accuracy

Erickson K., Singh M., Osmondson B., TSI Incorporated, US

The benefits of sizing aerosolized submicrometer particles using an electrical mobility sizing technique have been well documented. This type of analytical tool has been found to be able to measure particle diameter with an uncertainty [...]
