Researchers use graphene for 'super' audio headphones

Researchers at the University of California at Berkeley have found an intriguing application for graphene, headphone loudspeakers.

It is the low density and high mechanical strength of the new semiconductor material which makes it attractive for wide-frequency-response electrostatic audio speaker design.

“Low mass ensures good high frequency response…

Nanofibres – a maturing technology explained

Electrospinning is now established as a commercially viable manufacturing process with nanofibres of a range of different polymers now readily available, either as standard product or as “specials”, writes  Professor Bob Stevens, Professor of Smart Materials and Devices at Nottingham Trent University

Applications for these nanofibres are potentially in many…

UK scientists work on 'super-fridge'

Scientists at the National Physical Laboratory (NPL) and Imperial College are working on a project which they say “could completely change the refrigeration industry”.

Traditional refrigeration methods could be replaced by a more efficient and environmentally friendly cooling alternative which uses the electrocaloric effect to develop new methods of cooling…

US researchers discover superconductor "better than graphene"

Researchers in the US believe they may have discovered a new ‘super-conductive’ material which could out-perform graphene.

Like graphene it is a material with a single layer of atoms, but unlike graphene it is constructed from a single layer of tin atoms.

The material has been called “stanene…

European launches €1bn graphene research project

The Europe Union has launched a €1bn research initiative for the graphene semiconductor material technology.

Launched in Gothenburg last week, the Graphene Flagship was selected as one of Europe’s first technology flagships by the European Commission in January 2013.

The initiative is divided into two separate phases: a 30…

Science: Nanotube-coated spider silk promises flexible medical sensors

Spider silk darkened with a coating of carbon nanotubes can tell if your heart just skipped a beat.

Following a few simple steps, researchers have made a silk-nanotube hybrid that is tough, flexible and electrically conductive. The material might find uses in a range of bendy medical sensors.

Long…
