Magnetic Bistability at a Record High Temperature in a Sub-Monolayer of Endohedral Fullerenes
A team of the Leibniz Institute for Solid State Research (IFW) from Dresden, Germany, led by Dr Alexey Popov has now demonstrated a record blocking temperature of 28 Kelvin at which the magnetic bistability still survives in a submonolayer of a chemically functionalized species of endofullerenes. In this research, X-ray magnetic circular dichroism measurements at low temperatures and high magnetic field at the X-Treme beam line are crucial. The results pave the way toward using such single-molecule magnets as information carriers or magnetic bits.

NET ZERO Day of the four RIs at Empa
Climate change is one of the biggest challenges humanity is facing. It requires an approach, in which competences and capacities in research are combined across Switzerland to develop solutions for a transformation of our society towards net zero CO2 emissions.
Towards in situ imaging of electrolyte physical and chemical changes in Li-ion batteries
The Lithium conducting electrolyte is a critical component of Li-ion batteries, as it has an important impact on performance and its durability, in particular in case of extreme environmental conditions. At low temperatures, a partial solidification can occur, while high temperatures can promote the degradation of the electrolyte. Using time-of-flight (ToF) neutron radiography, the possibility of imaging such changes in a fully non-invasive manner was demonstrated for the first time.
Direct evidence of cobalt oxyhydroxide formation on a LSCO perovskite water splitting catalyst
In situ and ex situ ambient pressure X-ray photoelectron spectroscopy have been used to investigate the solid-liquid interface of a LSCO water splitting catalyst. Experimental results, supported by theoretical simulations of the core-electron binding energy, detect the formation of cobalt oxyhydroxide under working conditions.

Temperature and Reaction Environment Influence the Nature of Platinum Species Supported on Ceria
The evolution of atomically dispersed platinum species on ceria has been investigated by means of ambient pressure X-ray photoelectron spectroscopy and X-ray absorption near edge structure spectroscopy. Experimental results, supported by the theoretical simulation of the phase diagram, show that atomically dispersed species evolve towards nanoparticles during the activation of the catalysts. Such an evolution is influenced by the temperature and the reaction environment.
Successful Ambizione Grant applicant
Patrik Winiger, Research Grant Advisor and Project Manager at ETH Zurich, successfully applied for the Ambizione Grant 2020 with the project “Macromolecular Aerosols in the Cryosphere from the Arctic to the Alps – MACrAA”. The idea was developed together with the Laboratory for Atmospheric Chemistry (LAC) at PSI. The LAC is a global leader in aerosol analytics and source identification.
