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.
Processing metals

Metals processing cash boost

Materials World magazine
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.
refuelling with nanofuels

Exploring nanofuels

Materials World magazine
Nanofuels are the subject of a new feasibility study at Queen Mary, University of London, UK. They could provide a more environmentally sustainable alternative to fossil fuels, say researchers. The concept is to inject wet and dry fuels made from silicon, aluminium or iron nanoparticles (separately, as single fuels) into internal combustion engines.
