A NIR-II-emitting chromium complex
Many applications, from fiber-optic telecommunications to biomedical imaging processes require substances that emit light in the near-infrared range (NIR). A research team in Switzerland has now developed the first chromium complex that emits light in the coveted, longer wavelength NIR-II range. ...
Sensors could be immensely improved with nanospheres
Researchers at ETH Zurich have trapped a tiny sphere measuring a hundred nanometres using laser light and slowed down its motion to the lowest quantum mechanical state. Based on this, one can study quantum effects in macroscopic objects and build extremely sensitive sensors. Why can atoms or ...
Signal transmission through dyes: Chemical light amplifiers ten times more efficient than before
When fluorescent dye molecules nestle perfectly together, something completely new is created: an excited state distributed over many molecules. Such collective excitations can be used in a variety of ways – for organic solar panels, in sensors, for ultrafast data transmission or in microscopy, ...
Solar technology from Synhelion to receive Innosuisse funding
Synhelion and Empa are conducting a joint research project, co-funded by the Swiss Innovation Agency Innosuisse, to further develop a high-temperature energy storage solution that is a key component in the production of climate-friendly solar fuels. The project will enable the cost-effective and ...
"Virtual chemist" finds molecules that have the same effect as a natural substance but are simpler and low-cost to produce
Artificial intelligence (AI) is able to recognise the biological activity of natural products in a targeted manner, as researchers at ETH Zurich have demonstrated. Moreover, AI helps to find molecules that have the same effect as a natural substance but are easier to manufacture. This opens up ...
New properties and phenomena
For the first time, University of Basel researchers have equipped an ultrathin semiconductor with superconducting contacts. These extremely thin materials with novel electronic and optical properties could pave the way for previously unimagined applications. Combined with superconductors, they ...
The electronic properties of graphene can be specifically modified by stretching the material evenly
Graphene consists of a single layer of carbon atoms arranged in a hexagonal lattice. The material is very flexible and has excellent electronic properties, making it attractive for numerous applications – electronic components in particular. Researchers led by Professor Christian Schönenberger at ...
More potentially hazardous chemicals are lurking in plastics than has been assumed
ETH Zurich researchers examined chemicals in plastics worldwide. They found an unexpectedly high number of substances of potential concern intentionally used in everyday plastic products. A lack of transparency limits management of these chemicals. Plastic is practical, cheap and incredibly ...
Hiding in the midst of trash are valuable bacteria that can degrade environmental toxins
Bacteria from an Indian landfill could help eliminate contaminated chemicals. The focus is on pesticides or brominated flame retardants, which accumulate in nature and in food chains. Researchers at Empa and Eawag used these bacteria to generate enzymes that can break down these dangerous ...
Closing anticipated in the first half of 2022
Clariant announced that it has reached definitive agreements for the divestment of its Pigments business to a consortium of Heubach Group (“Heubach”) and SK Capital Partners (“SK Capital”) at an Enterprise Value (EV) of CHF 805 million to CHF 855 million on a cash and debt free basis, depending ...
