Corrosion Protection by Multifunctional Stratified Coatings

Westcott S.L., Kotov N.A., Ostrander J.W., Mamedov A.A., Reust D.K., Roark J.P., Nomadics, Inc., US

We have demonstrated a hybrid coating consisting of both a stratified layer that incorporates corrosion inhibiting ions and a silicate barrier layer. The stratified layer is applied to the aluminum alloy using the layer-by-layer assembly [...]

Nanostructure of a High-Permeability, Hydrogen-Selective Inorganic Membrane

Oyama S.T., Lee D., Hacarlioglu P., Gu Y., Saraf R.F., Virginia Tech, US

This paper describes the preparation and properties of an inorganic membrane with permeability for H2 comparable to palladium and with over 99.9% selectivity over larger species like CO, CO2 and CH4. The membrane is a [...]

Synthesis and Characterization of Novel High-Temperature Stable Nanocomposite Catalysts

Kirchhoff M., Specht U., Veser G., University of Pittsburgh, US

Unusually active and sinter-resistant nanocomposite materials were synthesized by combining the high reactivity of nanosized noble metal particles with the excellent hightemperature stability of hexa-aluminates through a simple one-step microemulsion-templated sol-gel synthesis. The novel nanocomposite [...]

Nanotube Stochastic Resonance: Noise–enhanced Detection of Subthreshold Signals

Lee I.Y., Liu X., Kosko B., Zhou C., University of Southern California, US

Noise can help signal detection at the nano-level. Experiments on a single-walled carbon nanotube transistor confirm that a threshold is sufficient for a nondynamical system to exhibit stochastic resonance: a judicious amount of noise can [...]

Carbon Nanotube-based Sensor Devices for IC Performance Evaluation

Wright R.G., Kirkland L.V., Zgol M., Adebimpe D., Mulligan R., GMA Industries, Inc., US

A novel approach to the problem of identification of failed integrated circuits (ICs) on electronic circuit boards has been sought that would allow for drastically reducing the costs of the test equipment development and maintenance. [...]

Noncovalent Engineering of Carbon Nanotube Surfaces

Chen J., Ramasubramaniam R., Liu H., Zyvex Corporation, US

Single-walled carbon nanotubes (SWNTs), due to their novel structural, thermal, electrical, mechanical and optical properties, are expected to find applications in many fields. Pristine SWNTs are generally insoluble in common solvents, and difficult to functionalize [...]

Gated Carbon Nanotube Field Emission Enhancement and Regeneration by Hydrogen

Hsu D.S.Y., Shaw J.L., Naval Research Laboratory, US

We have previously demonstrated two different configurations of integrally gated carbon nanotube field emitter arrays (FEAs). CNTs were grown inside microfabricated gate apertures with and without silicon posts. Salient features of these in-situ grown microgated [...]
