The think tank Avenir Suisse today presented its latest publication entitled "Sustainable Powertrain Technologies". The key message is clear: an openness towards different technologies is needed to achieve the climate goal of "net zero" - meaning CO2 emissions - by the year 2050. Among the authors are Peter Richner and Christian Bach from Empa.

Topological materials are a new class of materials that could enable completely new types of electronic components and superconductors. In topological materials, electrons can behave differently than in conventional materials. The extent of these "exotic" phenomena depends on the so-called Chern number. New experiments have now shown that the theoretically predicted maximum value of the Chern number can be reached and even controlled in a real material.

With an X-ray experiment at the European Synchrotron ESRF in Grenoble (France), Empa researchers were able to demonstrate how well their real-time acoustic monitoring of laser weld seams works. With almost 90 percent reliability, they detected the formation of unwanted pores that impair the quality of weld seams. Thanks to a special evaluation method based on artificial intelligence (AI), the detection process is completed in just 70 milliseconds.

During more than 90 approaches to Zurich Airport conducted under the leadership of the Swiss SkyLab Foundation, researchers from Empa and the German Aerospace Center (DLR) tested an assistance system that supports pilots via a display during quiet and, at the same time, fuel-efficient approaches. The results show a measurable reduction in noise emissions and fuel consumption. Now the system, developed by DLR, is to be made ready for production.

A research team from Empa and EPFL has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic level. The special feature of the motor is that it moves exactly at the boundary between classical motion and quantum tunneling - and has revealed puzzling phenomena to researchers in the quantum realm.

Cement production has to drastically reduce its environmental footprint. Empa researchers are, therefore working on alternative cement recipes that cause significantly fewer emissions or can even bind the greenhouse gas carbon dioxide.

Researchers have succeeded in applying aerogels to microelectronics: Aerogels based on cellulose nanofibers can effectively shield electromagnetic radiation over a wide frequency range - and they are unrivalled in terms of weight.

The circular economy is gaining a foothold in more and more areas: Some have already established business models, in others it is only visible in visionary pioneering projects. Where are the hurdles to a functioning circular economy, and how can they be overcome? Questions like those were discussed among the participants of the CE2 Lab on 23 June 2020 organized by the Swiss Economic Forum, Empa and the Swiss National Research Program "Sustainable Economy" (NRP 73).

In order to reduce the number of animal experiments in research, alternative methods are being sought. This is a particular challenge if the safety of substances that have hardly been studied is to be ensured, for instance, the completely new class of nanomaterials. To accomplish just that, Empa researchers are now combining test tube experiments with mathematical modelling.

Scientists of Empa and EPFL have developed a fully transparent surgical mask that will soon be produced on an industrial scale. The new startup HMCARE will market the masks and has already raised CHF 1 million to develop the manufacturing process.

Graphene triangles with an edge length of only a few atoms behave like peculiar quantum magnets. When two of these nano-triangles are joined, a "quantum entanglement" of their magnetic moments takes place: the structure becomes antiferromagnetic. This could be a breakthrough for future magnetic materials, and another step towards spintronics. An international group led by Empa researchers recently published the results in the journal "Angewandte Chemie".
