SLF researchers chase snow crystals around in circles in the wind tunnel. This is how they track down snow phenomena.

EPFL researchers have published a method for 3D-printing an ink that contains calcium carbonate-producing bacteria. The 3D-printed mineralized bio-composite is unprecedently strong, light, and environmentally friendly, with a range of applications from art to biomedicine.

Ice cores are a unique climate archive. Thanks to a new method developed by researchers at the University of Bern and Empa, greenhouse gas concentrations in 1.5 million year old ice can be measured even more accurately. The EU project “Beyond EPICA” with the participation of the University of Bern aims to recover such old ice in Antarctica.

Three institutes in the ETH Domain are conducting research on so-called perovskite-based optoelectronics, such as solar cells, photodetectors, and light-emitting diodes (LEDs). In a project called AMYS, labs of EPFL, ETH Zurich and Empa have now joined forces for four years to explore new chemical compositions, but also simple and scalable low cost production methods.

The Standard Model of particle physics describes our visible universe with incredible precision. Yet researchers are not entirely satisfied with it and are trying to find gaps in the theory. PSI’s unique infrastructures play a key part in their mind-boggling experiments.

Replacement parts for car repairs have a negative impact on the environment. By consistently repairing instead of replacing windshields and bumpers alone, Switzerland could save over 1000 tons of CO₂ per year. The insurance company AXA is now offering an assessment for repair workshops and introducing an industry label – based, among other things, on a study led by Empa researchers.
