Producing fertiliser without carbon emissions

Researchers at ETH Zurich and the Carnegie Institution for Science have shown how nitrogen fertiliser could be produced more sustainably. This is necessary not only to protect the climate, but also to reduce dependence on imported natural gas and to increase food security.

Gold-based passive heating for eyewear

Researchers from ETH Zurich have developed a new transparent gold nanocoating that harnesses sunlight to heat the lenses of glasses, thereby preventing them from fogging in humid conditions. This coating could potentially also be applied to car windshields.

Chip lets scientists study biocement formation in real-time

Scientists from EPFL and the University of Lausanne have used a chip that was originally designed for environmental science to study the properties of biocement formation. This material has the potential to replace traditional cement binders in certain civil engineering applications.

Sustainable clean drinking water solution

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

A new device for early diagnosis of degenerative eye disorders

Researchers at an EPFL lab have developed an ophthalmological device that can be used to diagnose some degenerative eye disorders long before the onset of the first symptoms. In early clinical trials, the prototype was shown to produce images with a sufficient degree of precision in just five seconds.

Stable in all kinds of shapes

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.
