Nanostructured SnO

This paper describes the morphology, stoichiometry, microstructure and gas sensing properties of nano clustered SnOx thin films prepared by Sn evaporation followed by the Rheotaxial Growth and Thermal Oxidation (RGTO) process. Electron microscopy was used to investigate, in detail, the evolution of the films as the oxidation temperature was increased. The results showed that the contact angle, ...

Nanostructured Silicon Success

A reduction in the size of integrated optical devices and components while maintaining a high level of performance is a key challenge in photonics. The footprint of devices becomes even more critical for applications with limited physical space such as on-chip, silicon-based photonic devices. Optical interconnects are recently emerging as a promising approach for onand off-chip communications o...

Optimized Nanostructured TiO2 Photocatalysts

Titania is the most widely studied photocatalyst. In its mixed-phase configuration ( anatase–rutile form) – as manifested in the commercially available P25 Degussa material – titania was previously found to exhibit the best photocatalytic properties reported for the pure system. A great deal of published research by various workers in the field has not fully explained the underlying mechanism f...

Nanostructured sulfur cathodes.

Rechargeable Li/S batteries have attracted significant attention lately due to their high specific energy and low cost. They are promising candidates for applications, including portable electronics, electric vehicles and grid-level energy storage. However, poor cycle life and low power capability are major technical obstacles. Various nanostructured sulfur cathodes have been developed to addre...
