Super light dampers for low tones

A team of Empa acoustic researchers has built macroscopic crystal structures that use internal rotation to attenuate the propagation of waves. The method makes it possible to build very light and stiff materials that can also 'swallow' low frequencies very well.

Vibration in one direction only

For many applications, having materials that transmit vibrations in one direction, but not in the other, would be extremely useful. In nature, such materials do not exist, but a group of physicists has now designed a metamaterial that can do just that.

Water + air + electricity = hydrogen peroxide

The novel electrosynthesis process uses an oxidized carbon nanoparticle-based catalyst and could enable point-of-use production of pure hydrogen peroxide solutions, eliminating the need to transport the concentrated chemical, which is hazardous.

A graphene filter to purify methane from biogas

Scientists that developed a graphene filter to improve the quality of drinking water have discovered a new application for the very thin form of carbon - the ability for graphene to purify methane from biogas produced in wastewater plants.
