Temporal sequence of photochemical reaction in individual aerosol particles observed with high resolution
21-Apr-2022
Aerosols in the atmosphere react to incident sunlight. This light is amplified in the interior of the aerosol droplets and particles, accelerating reactions. ETH researchers have now been able to demonstrate and quantify this effect and recommend factoring it into future climate models. Liquid ...
New concept for a high-precision quantum sensor
08-Apr-2022
Sensors are a pillar of the Internet of Things, providing the data to control all sorts of objects. Here, precision is essential, and this is where quantum technologies could make a difference. Researchers in Innsbruck and Zurich are now demonstrating how nanoparticles in tiny optical resonators ...
Researchers at PSI and ETH Zurich have observed for the first time how tiny magnets in a special layout align themselves solely as a result of temperature changes
06-Apr-2022
This view into processes that take place within so-called artificial spin ice could play an important role in the development of novel high-performance computers. When water freezes to form ice, the water molecules, with their hydrogen and oxygen atoms, arrange themselves in a complex ...
First step towards genuine plastic recycling
25-Mar-2022
A team of ETH researchers led by Athina Anastasaki have succeeded in breaking down plastic into its molecular building blocks and in recovering over 90 percent of them. A first step towards genuine plastic recycling. The chemical industry has a long tradition of producing polymers. This involves ...
Detecting defects at an early stage
02-Mar-2022
Sounds provide important information about how well a machine is running. ETH researchers have now developed a new machine learning method that automatically detects whether a machine is "healthy" or requires maintenance. Whether railway wheels or generators in a power plant, whether pumps or ...
Researchers have created artificial colours by 3D printing certain nanostructures inspired by those of a butterfly
11-Feb-2022
For their new technology, scientists in the group of Andrew deMello, Professor of Biochemical Engineering, drew inspiration from butterflies. The wings of the species Cynandra opis, native to tropical Africa, are decorated with brilliant colours. These are produced by extremely intricate regular ...
More than 99 percent of the most widely produced chemicals aren’t sustainable
04-Feb-2022
For the first time, researchers at ETH Zurich have calculated in absolute figures the extent to which the production of chemicals is currently interfering with nature worldwide – and the results are staggering. In addition to greenhouse gas emissions, the new method also takes land use and ...
07-Dec-2021
After analysing the global plastics value chain, ETH researchers have revealed that the impact of plastics on climate and health is bigger than originally thought due to the increased use of coal for process heat, electricity and as a raw material in production. Global demand for them has ...
Airy and efficient
02-Dec-2021
Researchers at ETH Zurich have developed a new photocatalyst made from an aerogel that could enable more efficient hydrogen production. The key is sophisticated pretreatment of the material. Aerogels are extraordinary materials that have set Guinness World Records more than a dozen times, ...
ETH Zurich spin-off relies on a new material that efficiently converts electrical signals into optical ones
30-Nov-2021
Increasingly large amounts of data are being sent back and forth around the world. To ensure that this exchange continues to function smoothly, new solutions are needed at the interfaces between chips and optical fibres. The ETH Zurich spin-off Lumiphase relies on a new material that efficiently ...
