Quick and easy nanoarrays

Materials World magazine
A fast and simple technique for producing nanostructured gallium arsenide arrays using lithographic patterning has been developed by researchers at Oxford University, UK. This could be used for improved data storage in advanced optical, electronic or magnetic applications

Powering up composites

Materials World magazine
Demand for small, electrically driven unmanned air vehicles (SEUAVs) in the military and civil sectors has led researchers at The Welding Institute (TWI) in Cambridge, UK, to explore the use of embedded fuel cells to help power lightweight composite structures, typically constructed from carbon or glass fibre-reinforced epoxy.

Ion beam detective

Materials World magazine
Using particle-induced X-ray emission (PIXE) on an ion microprobe, scientists at the University of Surrey, UK were able to pick up trace volumes of gunshot residueselements, which usually go undetected by scanning electron microscopy with energy dispersive X-ray spectroscopy.

In contact for food safety

Materials World magazine
The adoption of the Materials and Articles in Contact with Food Regulations 2008 in May increases the challenges for the packaging industry. The regulation requires a Declaration of Compliance to accompany all food contact plastics. This article examines the changes and how to comply with the new legislation.

Polymers pave the way

Materials World magazine
PET waste from bottles, cartons and yoghurt pots has been redirected from landfill and transformed into cement-free concrete paving blocks thanks to a EUREKA funded project called Sandplast.
