Fracture of Vacancy-defected Carbon Nanotubes and Their Embedded Composites

Xiao S.P., Hou W.Y., The University of Iowa, US

In this paper, we investigate the effects of vacancy defects on the fracture of carbon nanotubes and carbon nanotube/aluminum composites. Our studies show that even a one-atom vacancy defect can dramatically reduce the failure stresses [...]

Additives containing Nano Metal Oxides for enhanced scratch resistance in Coating Formulations

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 [...]

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 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 [...]

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 [...]

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 [...]

Photochemical Alteration of the Stability of Polymer Nano-Agglomerates

Seipenbusch M., Rothenbacher S., Weber A.P., Salas-Vicente J., Braun A.M., Kasper G., University of Karlsruhe, DE

Interparticle adhesion in the nano-regime leads to undesired stable agglomerates in particulate products. On one hand, the high surface energies of nanoparticles favor the reduction of overall surface area by maximization of the number of [...]

Synthesis of visible light active nanocrystalline bismuth oxide based photocatalysts

Akurati K.K., Vital A., Reifler F., Ritter A., Graule T., Swiss federal laboratories for materials science & technology, EMPA, CH

Photocatalysis phenomenon has attracted considerable interest in recent years because of its usage in water purification, environmental cleaning, solar energy conversion and generation of alternative energy resources. To date, TiO2 has undoubtedly proven to be [...]
