Novel technique developed to grow semiconductors on silicon

Materials World magazine
AmberWave Systems, based in Salem, USA, has developed a novel technique to grow semiconductors, such as germanium, gallium arsenide and indium phosphide, on silicon. Researchers hope the method will lead to faster and smaller transistors, and cheaper lasers and photonic devices. Faster and smaller transistors are the key to extending Moore's Law - the chip industry axiom that predicts doubling the number of transistors in an integrated electronic circuit every two years will improve performance. The team has epitaxially grown non-silicon semiconductors through chemical vapour deposition.

Compound composite challenges

Materials World magazine
A EUREKA SURFAS project made up of French and Swiss researchers seeks to address the problems surrounding the use of sheet moulding compound (SMC) composites in automotives. The material could reduce the car's weight and decrease carbon emissions but their use has been limited due to cracks and blisters appearing on the surface of components.

Record breaking magnet

Materials World magazine
Scientists in the USA claim to have broken the world record for a magnetic field created by a superconducting magnet, with the development of 26.8 tesla superconducting magnet. The test coil was wound using semiconductor yttrium barium copper oxide.

Proskills succeeds in bid to establish National Skills Academy

Materials World magazine
Proskills has succeeded in its bid to establish a National Skills Academy (NSA) designed to deliver technical and management skills for the processing and manufacturing industries, including building products, coatings, glass, printing and extractive minerals.

Destroying bacteria with bioactive packaging paper

Packaging Professional magazine
Canadian researchers are developing a bioactive packaging paper that they believe will detect and kill bacteria and viruses present in food and drinks in a matter of seconds. Using standard paper, the Sentinel Bioactive Paper Network is developing a bioactive ink that could be printed, coated or impregnated onto or into the material, to identify individual pathogens.
