Effect of ZrO2 Additives on the Nanomechanical Properties of Spark Plasma Sintered 93WC/7-xCo/xZrO2-2mol% Y2O3 Powders Prepared by High-Energy Ball Milling

El-Eskandarany M.S., Al-Hazza A., Al-Hajji L., Alduweesh A., Ahmed S., Al-Rowayeh A., Kuwait Institute for Scientific Research, KISR, KW

A high-energy ball milling technique was employed to prepare ultrafine cemented carbide nanocomposite powders with compositions (wt.%) of 93WC/7-xCo/xZrO2-2mol% Y2O3 powders (x=0, 1, 2, 3, 4, 5, 6, 7 wt%). The nanocomposite powders obtained after [...]

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 [...]

Atomistic Simulations of Electronic Structure in Realistically-Sized Wurtzite InN/GaN Quantum Dots

Yalavarthi K., Gaddipati V., Ahmed S., Southern Illinois University at Carbondale, US

In this work, within a fully atomistic framework, we investigate the electronic structure of wurtzite InN quantum dots self-assembled on GaN substrates. The main objectives are two-fold: (1) to explore the origin, nature and the [...]
