Refrigeration using magnetic cooling technology

Materials World magazine
Researchers from the Risoe National Laboratory - Technical University of Denmark, in Roskilde, have used magnetic cooling technology to bring environmentally friendly refrigeration closer to development. Magnetic cooling technology exploits materials such as gadolinium which heat up when exposed to a magnetic field and cool down when that field is removed.

Electronic paper displays from photonic crystals

Materials World magazine
P-Ink, a technology that employs photonic crystals and the light reflected between them to create flexible electronic-paper displays with improved colour and resolution, has been created by Opalux, a company based in Toronto, Canada.

Anti-corrosion technology for automotives with no heavy metals

Materials World magazine
International Ford Motor Company has developed an anti-corrosion coating that does not use heavy metals. The company claims the pre-treatment process is more efficient as it reduces water usage in automotive paint shops by half and decreases the production of waste sludge by 90%. The technique makes use of a zirconium oxide vehicle bath rather than the conventional heavy metal zinc phosphate bath

Nanoparticle production

Materials World magazine
Scientists from the North West Laser Engineering Consortium at the Universities of Liverpool and Manchester, UK, say they have developed a more efficient way of producing nanoparticles using a continuous wave (CW) fibre laser.
