Nanogold for multiple drug delivery

Materials World magazine
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.

Automotive technology aids synthetic bone manufacture

Materials World magazine
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.

Dough moulding for resilient ceramics

Materials World magazine
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.

Biogas field of dreams?

Materials World magazine
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.
