When thin becomes thinner
When thin becomes thinner
If you start with a two-dimensional ribbon and make it narrower and narrower, when does it stop being a ribbon and start being a one-dimensional line? Scientists from Utrecht University and the University of Twente made one-atom-thick ultrathin nanoribbons consisting of germanium atoms. They have shown that this system exhibits amazing properties that can be useful, for example, in quantum computing.

Spintronics: significant progress
An international research team has achieved a breakthrough in atomically thin antiferromagnetic tunnel junctions. This shows the great potential of antiferromagnetic materials for storage technology. Spintronics (spin electronics) deals with the use of electron spin in electronic devices. In contrast to conventional electronics, which only uses the charge of the electrons, spintronics also uses the spin of the electrons, i.e. a "direction of rotation" at the atomic level, to store and process information.

One-way street for sound waves
One-way street for sound waves
Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves. Be it water, light or sound: waves usually propagate in the same way forwards as in the backward direction. As a consequence, when we are speaking to someone standing some distance away from us, that person can hear us as well as we can hear them.
