Exploring laser excitation of gold nanoparticles will enhance international research into these materials for controlled drug delivery, say researchers at MIT, Cambridge, USA. Gold nanorods of different shapes respond to different
infrared wavelengths, enabling selective melting of the carriers and release of the various medicines attached to their surfaces.
In an unusual example of technology transfer, the manufacturing process for automotive catalytic converters has been applied to synthetic bone implants.
Scientists at the University of Warwick, UK, claim to have developed monolith bioceramic scaffolds that combine strength and porosity for
load-bearing applications, such as large fractures and spinal fusions.
UK researchers have created low-cost ceramic compounds with improved thermal and impact properties by applying a fibre reinforcing technique used for polymer moulding composites. These ceramics, made from calcium carbonate, calcium phosphate, and an aluminium trihydroxide hardener, could have applications in automotive heat shields or composite aircraft wings.
German researchers are building what they say is the first-ever biogas pilot plant to run entirely on agricultural waste, while achieving 30% more biogas than previous facilities. This technique could create a sustainable source of energy that does
not rely on edible materials, preventing competition for food crops and land.
As the full brunt of the recession starts to take effect, Materials World talks to 18 leading members of the UK engineering and manufacturing industries to get their views
about the effects of the economic climate on their sector and where future redemption may lie.

A hemp or flax-based bioplastic that uses 90% less sulphur has made the material suitable for consumer goods such as toys and electronics, say researchers at the Fraunhofer Institute for Chemical Technology in Pfinztal, Germany. At the end-of-life, the plastic can be broken down and re-pelletised.
More support is needed for the UK automotive industry says Unite, the UK's biggest union, in response to the Government's £2.3bln relief package for the sector. Car producers in the UK are hanging on by a thread because of a lack of
credit from the banks and a dramatic fall in demand for cars,' says
Derek Simpson of Unite.
A £2.3bln package of measures to help the UK automotive industry survive the current global economic crisis has been accounced by Lord Peter Mandelson, Business Secretary. The sector is 'in the front line of the downturn', says Mandelson.
Laptop screens that run on a fraction of the power used by conventional screens are being developed by US company Pixel Qi, based in San Bruno. The firm claims it has redesigned traditional liquid crystal display materials and production techniques to improve performance.
American soldiers could soon be taking a new piece of kit onto the battlefield – a portable solar-powered generator smaller than a laptop. The Very High Efficiency Solar Cell (VHESC) programme is made up of a group of US universities, Government research laboratories and companies, and aims to reduce the weight of batteries a soldier has to carry and simplify logistical supply chains.
