The antibacterial properties of silver-coated textiles are popular in the fields of sport and medicine. A team at Empa has now investigated how different silver coatings behave in the washing machine, and they have discovered something important: textiles with nano-coatings release fewer nano-particles into the washing water than those with normal coatings.

Producing hydrogen with sunlight18 June 2014
Collecting light with artificial moth eyes

All over the world researchers are investigating solar cells which imitate plant photosynthesis, using sunlight and water to create synthetic fuels such as hydrogen. Empa researchers have developed such a photoelectrochemical cell, recreating a moth’s eye to drastically increase its light collecting efficiency. The cell is made of cheap raw materials – iron and tungsten oxide..

«ONE TWO WE» shows first successes16 June 2014
Reducing CO2 emissions through sustainable food

In November last year Empa became a partner in the climate protection program «ONE TWO WE», established by the catering concern SV group and the environmental organisation WWF. The aim of the program is to reduce environmental damage caused by the production of food-stuffs. The results of an initial assessment have now been publicised: the CO2 emissions of Empa's staff restaurant sank by 6 per cent compared to the same period last year.
