Batteries for transporting mobility into the future

High-​performance batteries are key to the comprehensive roll-​out of e-​mobility: ETH Pioneer Fellow Paul Baade is looking into how to manufacture them more cost-​effectively

09-Sep-2021

From 0 to 100 km/h in 2.6 seconds. Top speeds of 120 km/h. All powered by just one battery. This is “julier”, the first electric race car to win the Formula Student competition in 2013 against cars with traditional combustion engines. Paul Baade was one of the brains behind the battery back when ...

Changes in colour indicate deformations

Fluorescence indicates overstressed parts

24-Aug-2021

ETH Zurich researchers have developed a new type of laminate that changes colour as soon as the material is deformed. This way, the materials researchers can kill two birds with one stone: a lightweight composite material that inspects itself. Lightweight construction has found its way into many ...

A promising breakthrough: Nanocrystals made of amalgam

09-Aug-2021

Researchers at ETH have managed to produce nanocrystals made of two different metals using an amalgamation process whereby a liquid metal penetrates a solid one. This new and surprisingly intuitive technique makes it possible to produce a vast array of intermetallic nanocrystals with tailored ...

High-precision frequency measurement

03-Aug-2021

Many scientific experiments require highly precise time measurements with the help of a clearly defined frequency. Now, a new approach allows the direct comparison of frequency measurements in the lab with the atomic clock in Bern, Switzerland. For many scientific experiments, today’s researchers ...

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 ...

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 ...

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 ...

Shiny mega-crystals that build themselves

New mega-crystals exhibit unique properties such as superfluorescence and may well usher in a new era in materials science

28-May-2021

An international team led by Empa and ETH Zurich researchers is playing with shape-engineered nanoscale building blocks that are up to 100-times larger than atoms and ions. And although these nano "Lego bricks" interact with each other with forces vastly different and much weaker than those ...

A material-keyboard made of graphene

Insulator and superconductor in the same material

07-May-2021

Researchers at ETH Zurich have succeeded in turning specially prepared graphene flakes either into insulators or into superconductors by applying an electric voltage. This technique even works locally, meaning that in the same graphene flake regions with completely different physical properties ...

Nanoplastics – an underestimated problem?

Tiny plastic particles in the environment

06-May-2021

The images leave no one cold: giant vortices of floating plastic trash in the world's oceans with sometimes devastating consequences for their inhabitants – the sobering legacy of our modern lifestyle. Weathering and degradation processes produce countless tiny particles that can now be detected ...
