Researchers at MPI-CPfS have shown, through muon implantation experiments, that in Sr2RuO4 the onset of superconductivity causes spontaneous electrical currents to flow. They did this by showing that the onset of these currents splits from the main superconducting transition under uniaxial stress, which proves that it is a distinct transition, not a measurement artefact.

Green hydrogen - produced from water electrolysis by using sustainable electricity - is getting more attention due to its potential to be used as energy carrier as well as building block for various industrial processes. Among both half-reactions of water electrolysis, Oxygen Evolution Reaction (OER) is kinetically more challenging and it requires advances in the development of innovative electrocatalysts.

A team of scientists from the MPI CPfS in the research field Chemical Metals Sciences prepared a new intermetallic compound by the high-pressure high-temperature technique. From quantum-chemical analysis, this material is formed by chain polyanions of Ge atoms and four-atomic cluster polycations Lu₄. It constitutes an important step in the understanding of chemical bonding in intermetallic compounds.
