Carbon-neutral fuel made from sunlight and air: Two spin-offs already founded
Researchers from ETH Zurich have developed a novel technology that produces liquid hydrocarbon fuels exclusively from sunlight and air. For the first time worldwide they demonstrate the entire thermochemical process chain under real field conditions. The new solar mini-refinery is located on the ...
Floating power plants
Paper, tin cans, glass - the world recycles as much as possible. So why not declare the greenhouse gas carbon dioxide (CO2) a recycling product as well? Liquid fuels based on carbon will continue to play an important role in the future - despite international efforts to reduce them. So it seems ...
Chemical processes extend radiocarbon dating
Researchers at ETH Zurich have developed a process that can provide conclusive evidence with regard to modern fakes of paintings, even in cases where the forger used old materials. This verification process requires less than 200 micrograms of paint. Art forgeries have been around since time ...
Many wastewater treatment plants do not completely remove chemical substances from wastewater.
Microcontaminants place a considerable burden on our water courses, but removing them from wastewater requires considerable technical resources. Now, ETH researchers have developed an approach that allows the efficient removal of these problematic substances. In our everyday lives, we all use a ...
Sand, coffee grounds and rice behave very differently than water or oil, but under certain conditions they will suddenly exhibit astonishing similarities. Scientists have found a way to better understand the behaviour of granular materials. Sand, rice and coffee are all examples of granular ...
ETH researchers have cooled a nanoparticle to a record low temperature, thanks to a sophisticated experimental set-up that uses scattered laser light for cooling. Until now, no one has ever cooled a nanoparticle to such low temperatures in a photon cage: Dominik Windey and René Reimann – a ...
Can water reach minus 263 degrees Celsius without turning into ice? Yes it can, say researchers from ETH Zurich and the University of Zurich, if it is confined in nanometre-scale lipid channels. Making ice cubes is a simple process: you take a plastic ice-cube tray like you’d find in most ...
A compass pointing West
Researchers from the Paul Scherrer Institute PSI in Villigen and the ETH Zurich have discovered a special phenomenon in magnets. This phenomenon takes place at the nanoscale and enables magnets to be assembled in unusual configurations, which could also be useful for computer technology and data ...
An international research project led by scientists from ETH Zurich has determined the amount of man-made CO2 emissions taken up by the ocean between 1994 and 2007. Not all of the CO2 generated during the combustion of fossil fuels remains in the atmosphere and contributes to global warming. The ...
A new coating developed by ETH researchers prevents fogging on transparent surfaces. Rather than using electricity, the coating relies on sunlight to heat the surface. Anyone who skis, wears glasses, uses a camera or drives a car is familiar with the problem: if you come into a humid environment ...
