A multi-million pound grant has been awarded to the University of Sheffield's Institute for Microstructured and Mechanical Process Engineering (IMMPETUS) to help UK-based metals processing companies improve efficiency.
Optical microcircuits that integrate electronic functions may be achievable thanks to a new bonding technique to adhere gallium arsenide (GaAs) and indium phosphide (InP) substrates to create an active microring resonator. This could then be used to fuse the substrates to silicon wafers.
Scientists at Princeton University, USA, claim to have produced the first 3D metamaterial constructed entirely from semiconductors. They believe the new design could offer a cost effective way of creating negative refractive lenses for high-speed communications, medical diagnostics and detecting terrorist threats.
The UK-US Manufacturers Summit 07, held in Manchester, UK, from 16-18 October 2007, offered delegates tips on how to achieve best practice by introducing lean manufacturing, and improving the quality and efficiency of the supply chain.
A UK manufacturer of concrete masonry and clay lightweight aggregate blocks has achieved a 44.5% reduction in carbon dioxide emissions through the use of more energy efficient curing chambers and alternative aggregates.
