Spectroscopy and coherent scattering on catalysts for C-H bonds of saturated alkanes at the European XFEL
C-H bonds of saturated alkanes are inert and hence hard to break. Catalysis with 4d and 5d transition metal complexes in solution provides ways for C-H bond cleavage, whereas earth-abundant 3d metal catalysts have not been discovered to date. Raphael M. Jay from Uppsala University in Sweden and his team investigates how to make 3d metal complexes reactive for C-H activation. The...-

Investigation of ultrafast electron solvation dynamics in aqueous systems at European XFEL
During ionisation, electrons are knocked out of an atom. What remains are "holes". Both the ejected electrons and the holes can trigger chemical reactions in an extremely short time. This is particularly true in aqueous systems. Using X-ray absorption spectroscopy (XAS), the scientists from Linda Young's team at Argonne National Laboratory, USA, are investigating the ultrafast dynamics of...-

Towards Quantum Vacuum Birefringence using an X-ray Dark-field Technique at European XFEL
According to quantum field theory, the vacuum is not really "empty". For example, it can interact with strong electromagnetic fields. This extremely weak effect should also be visible in the scattering of X-ray photons in the optical field of strong laser fields - and be about two orders of magnitude stronger. Physicists call this light-by-light scattering. As part of the HIBEF collaboration...-

Femtosecond-XES characterization of spin-states and structures of transient iron(III)-oxyl species
Compounds of iron with oxygen are relevant for many processes - from the transport of oxygen in the blood to the corrosion of iron. However, many aspects of iron-oxygen chemistry are not yet fully understood. It is generally believed that the magnetic orientations of the electrons involved - the so-called spin state - also play an important role, e.g. in catalytic processes. Using...-

At the MID instrument of European XFEL, researchers can investigate the structure and dynamics of materials with molecular to atomic resolution. To do this, they focus X-ray pulses on the material to be studied from where the X-rays are scattered in different directions. The arrangement of the atoms in the material leads to a characteristic scattering pattern, which is recorded by a detector....-
