High velocity forming of fuel cell plates

A production process, based on high velocity metal forming, can manufacture fuel cell bipolar plates in a fraction of the time normally required, according to a technology firm in the USA. This could also make fuel cell production cheaper.

High speed patterning of hydrogels

Direct laser interference lithography can speed up micropatterning of hydrogels for biomedical applications with improved resolution, says Dr Andrés Lasagni in Germany.
Flat Flexible Loudspeaker

Speaking volumes with wafer-thin loudspeakers

Wafer-thin loudspeakers that project sound further than conventional models could transform public address systems in train stations, airports and shopping centres. The Flat Flexible Loudspeaker, from engineers at the University of Warwick, UK, is less than 0.25mm thick and emits planar directional sound waves.

Survival of the fittest in wave energy

Engineers at the University of Ghent, Belgium, are working on glass fibre/polyester floating point absorbers for wave energy conversion. They are designed to stay at sea for 20 years, surviving extreme offshore weather conditions.
