Infrared Held in a Pincer

A NIR-II-emitting chromium complex

23-Jul-2021

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. ...

Nanosphere at the quantum limit

Sensors could be immensely improved with nanospheres

21-Jul-2021

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 ...

Molecules in collective ecstasy

Signal transmission through dyes: Chemical light amplifiers ten times more efficient than before

15-Jul-2021

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, ...

A next step towards climate-friendly fuels

Solar technology from Synhelion to receive Innosuisse funding

08-Jul-2021

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 ...

Harnessing AI to discover new drugs inspired by nature

"Virtual chemist" finds molecules that have the same effect as a natural substance but are simpler and low-​cost to produce

08-Jul-2021

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 ...

Stretching changes the electronic properties of graphene

The electronic properties of graphene can be specifically modified by stretching the material evenly

05-Jul-2021

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 ...

Worrying insights into the chemicals in plastics

More potentially hazardous chemicals are lurking in plastics than has been assumed

24-Jun-2021

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 ...

Tailor-made enzymes for chemical toxins?

Hiding in the midst of trash are valuable bacteria that can degrade environmental toxins

21-Jun-2021

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 ...
