Cutting costs in optical fibres

Hollow-core optical fibres can be manufactured in a day rather than a week by changing their structure, reducing the overall cost of fabrication, according to scientists at Bath University, UK. They believe this could lead to faster and more powerful optical telecommunications, laser machining, and cheaper generation of X-ray or ultra-violet light for use in biomedical and surgical optics.

Electrospinning biomaterials for tendon repair

Scientists at The University of Manchester, UK, are investigating the use of electrospun polycaprolactone nanofibres to regenerate damaged tendons. Because the bundle of fibres replicates the morphology of tendon tissue, researchers envisage that the synthetic structure will perform the mechanical function of the tendon while it repairs itself, as well as act as a temporary scaffold to promote cell migration and new tissue formation.

Energy efficient silicon chip

A silicon chip with a DC/DC converter built directly onto it has been shown to operate at 0.3V, making it 10 times more energy efficent than standard electronic chips.

Exploring non-destructive techniques to conserve plastic artefacts

Plart – a museum dedicated to researching non-destructive testing for the restoration and conservation of plastic artefacts – opened on 25 January 2008 in Naples, Italy. The aim is to set up a characterisation and conservation protocol specific thermosetting plastics and thermoplastics. Polyurethane, PVC and cellulose acetate and nitrate materials are recognised as the most difficult materials to conserve from degradation.

Handling radioactive waste from nuclear power plants

Plans for waste assaying and disposal need to be at the forefront of all future nuclear builds. This was the conclusion at an event on Handling of Radioactive Materials held on 13 February 2008 in Birmingham, UK. Presentations covered site characterisation, recycling and reusing materials, decommissioning, nuclear facility layout, and engineering waste management solutions.
