The use of potassium bromide in the production of graphene on a copper surface can lead to better results. When potassium bromide molecules arrange themselves between graphene and copper, it results in electronic decoupling. This alters the electrical properties of the graphene produced, bringing them closer to pure graphene, as reported by physicists from the universities of Basel, Modena and Munich in the journal ACS Nano .
For the first time, physicists at the University of Basel have succeeded in measuring the magnetic properties of atomically thin van der Waals materials on the nanoscale. They used diamond quantum sensors to determine the strength of the magnetization of individual atomic layers of the material chromium triiodide. In addition, they found a long-sought explanation for the unusual magnetic properties of the material. The journal Science has published the findings.
The European Research Council has awarded two University of Basel scientists each a generously endowed ERC Advanced Grant. Biologist Professor Alex Schier and physicist Professor Ernst Meyer will each receive funding in the six figures for their innovative research projects.
The explanation of the observed light neutrino flavour oscillations requires new particles, absent in the present theory of elementary particles, the so-called “Standard Model”. Extensions of the Standard Model where these new particles are within reach of collider experiments often feature a pair of additional "heavy neutrinos”, with nearly equal masses. Physicists from the University of Basel have recently shown that the small mass difference is predicted in simple neutrino mass theories of this type, and that it leads to oscillations between heavy neutrino states and heavy antineutrino states. These heavy neutrinos and antineutrinos can be detected by their decays into leptons and antileptons of the Standard Model. For comparatively long-lived heavy neutrinos, the oscillations could be resolved at the next (high-luminosity) stage of LHCb, and at envisioned future particle colliders. Their observation would allow a deep insight into the origin of neutrino masses (Mod. Phys. Lett. A34 (2019)).
Physicists from the University of Basel have demonstrated spin alignment of free electrons within a two-dimensional material. Writing in the latest edition of Nature Nanotechnology, they described their observation of spontaneous spin polarization, which cannot occur in ideal two-dimensional materials according to a well-known theorem from the 1960s.
The international doctoral program “QUSTEC” will be established at the European Campus.
The project “Quantum Science and Technologies at the European Campus” (QUSTEC) has been selected by the European Commission as a joint international and interdisciplinary doctoral program in quantum sciences and technologies. Led by Eucor – The European Campus, it will bring together the Universities of Basel, Freiburg and Strasbourg, Karlsruhe Institute of Technology and IBM Research Zurich.
This video described a phenomenon during planar flow casting of amorphous metallic ribbons.
Moreover, the use of these amorphous metallic ribbons and the collaboration with industry is explained here.

We congratulate Christina for winning the prestigious Marie Sklodowska-Curie Fellowship. Her project "Engineering the dynamics of magnetic skyrmions using non-equilibrium protocols" will be carried out at the Californian Institute of Technology (Caltech) together with European partners at the University of Cologne.
Currently, Christina is a postdoctoral researcher in the group of Prof. Daniel Loss. Her research interests are in the field of magnetic systems with focus on the quantum dynamics of skyrmions.
We wish Christina continued success on her career path.
