Microring device prototype

Optical microcircuits with electrical properties

Materials World magazine
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.
Light passing through metamaterial

3D metamaterials from semiconductors

Materials World magazine
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.

Manufacturing best practice

Clay Technology magazine
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.

Energy efficient curing for concrete masonry and clay aggregates blocks

Clay Technology magazine
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.

Wireless bridge sensor powered by traffic vibrations

Materials World magazine
A novel wireless sensor for use on bridges can be powered by the vibrations of vehicles passing overhead. The device, made from piezoelectronics, measures temperature, humidity, light and pressure, and could function for years without requiring maintenance or battery replacement.
