Copper Displacement Deposition on Nanostructured Porous Silicon

Bandarenka H., Redko S., Nenzi P., Balucani M., Belarusian State University of Informatics and Radioelectronics, BY

In the present work we have demonstrated nanosized structures fabrication by the copper displacement deposition on electrochemically etched porous silicon. Peculiarity of such method is the convergence of copper reduction with porous silicon dissolution. Principal [...]

Photonic Sintering of Silver for Roll-to Roll-Printed Electronics

Ahmed S., Xenon Corporation, US

The use of high energy Pulsed Light is presented as a means of sintering printed nano- particle inks to form conductive traces on flexible substrates. These novel metal nanoparticle based inks are ideally suited for [...]

Characterization of Nanoparticle Release from Polymer Nanocomposites Due to Fire

Uddin N.M., Nyden M.R., National Institute of Standards and Technology, US

Studies are being conducted to understand the potential hazards associated with burning materials containing carbon nanotubes (CNTs) and nanofibers (CNFs) either in the process of incineration or in accidental fires. Some of the important questions [...]

Adhesion strength and superhydrophobicity in polyurethane/organoclay nanocomposites

Steele A., Bayer I., Yeong Y.H., Loth E., University of Virginia, US

Polyurethane coatings are used on many different materials and in a wide variety of applications due to its high durability and adaptable chemical composition. Although there are a number of reports on the fabrication of [...]

Wet organometallic chemistry for palladium nanoparticles synthesis performed in an organic media and under supercritical conditions in microreactors

Desportes S., Tidona B., von Rohr Ph.R., ETH Zürich, CH

Nanoparticles are been produced in a microreactor under different operating conditions, spefically under supercritical CO2. The known organometallic chemistry is been used to create Pd-nanoparticles. Compared to the batch process the processing time could be [...]

Silver Chloride – Wool Nanohybrid Materials: Synthesis and Properties

Johnston J.H., Kelly F.M., Victoria University of Wellington, NZ

The development and characterisation of a new nanowool hybrid material formed by functionalising merino wool with silver chloride nanoparticles is presented. The nanoparticles are formed directly on the surface and inside the wool fibre. Initially [...]

Dielectric Constant, Loss and Breakdown for Ultem containing BaTiO3 Nanoparticles

Lomax E.A., Lomax J.F., Lomax E.A., Lomax J.F., Lu S.C., Calame J.P., Fontanella J.J., Edmondson C.A., Wintersgill M.C., U.S. Naval Academy, US

The need for improved energy storage devices prompts interest in developing new dielectric materials for high energy capacitors. This work reports data on the properties of cast films of BaTiO3 nanoparticles (high dielectric) in the [...]

Single Particle Resolution Zeta Potential Technique

Griffiths D., Bernt W., Hole P., Sullivan J., Malloy A., Carr B., NanoSight USA, US

A novel addition to a technique for the analysis of nanoparticles in a suspension is described. The Nanoparticle Tracking Analysis (NTA) technique visualizes then sizes individual nanoparticles, based on their Brownian motion. Unlike classical light [...]

The influence of surface termination on growth of cupper clusters

Xiao L., Srinivasan J., Subramanian L., Accelrys Inc., US

Oxide supported transition metal catalysts are widely used in variety of heterogeneous catalytic processes. Knowledge of the interaction of metals with oxide surfaces provides insight into understanding a broad variety of properties of the catalysts. [...]
