Hydrophobic treatment for jute fibres based on zinc oxide nanoparticles

Arfaoui M.A., Dolez P.I., Dubé M., David É., CTT Group, CA

The use of zinc oxide (ZnO) nanoparticles in the textile sector has been the subject of several studies aimed at making fibrous materials multifunctional and more resistant. This could open a wide range of new [...]

Rapid Combustion Synthesis of Zinc Oxide Nanostructures

Merchan-Merchan W., Farmahini Farahani M., University of Oklahoma, US

In this contribution we show that Zn oxide nanostructures of various morphologies can be formed at high rates by using a counter-flow flame. A 1.0-mm in diameter Zn probes with a purity of ~99.99% is [...]

Synthesis of Nano-Sized Ferrite Materials for H2 Generation from High Temperature Water-Splitting Reaction

Bhosale R., Shende R., Puszynski J., South Dakota School of Mines & Technology, US

As the current research trends in H2 generation using thermochemical water-splitting reaction are focused towards lowering the H2 generation temperatures, it is believed that the nano-sized ferrite materials with porous morphology will significantly reduce the [...]
