ETH Zurich
ETH postdoc Olivier Gröninger is improving the drinking water supply for people in rural areas of South America with his Openversum project. This benefits not only the families but also the local economy and the climate
Stable in all kinds of shapes
Research
ETH Zurich
ETH Zurich researchers have developed a structure that can switch between stable shapes as needed while being remarkably simple to produce. The key lies in a clever combination of base materials.
Renewable cellulose-based fillers

Empa
The substitution of petrochemical materials with those obtained from renewable raw materials is an important step towards increasing sustainability. In just two years of intensive and open collaboration between Empa and the Datwyler Schweiz AG as part of an Innosuisse project, a process was successfully developed that brought together the worlds of cellulose and rubbers. 
Flexible solar cells with record efficiency of 22.2%
Research
Empa
One year after announcing an efficiency record, Empa scientists have achieved a new mark of 22.2% for flexible CIGS solar cell on polymer film. Solar cells of this type are especially suited for applications on buildings, vehicles, satellites, airships, and mobile devices.
Hitting the bull’s eye
Research
Empa
In the FOXIP project, researchers form Empa, EPFL and the Paul Scherrer Institute attempted to print thin-film transistors with metal oxides onto heat-sensitive materials such as paper or PET. The goal was ultimately not achieved, but those involved consider the project a success – because of a new printing ink and a transistor with "memory effect".
Empa scientist among winners in Physical sciences

Which are the next walls to fall in science and society? Guided by this question, the brightest minds in the international scientific community submitted their groundbreaking projects for the prestigious "Falling Walls Science Breakthrough of the Year 2022". The jury has made its choice - selecting among 95 nominations a project led by Empa researcher Roman Fasel as one of ten winners in the "Physical Sciences" category.
