Investigation of ultrafast electronic structure dynamics in correlated oxides at European XFEL

Mark P. M. Dean from Brookhaven National Laboratory (BNL) and Sophia TenHuisen from Harvard University, USA, are researching the cuprate La2-xSrxCuO4 at the SCS (Spectroscopy & Coherent Scattering) instrument of European XFEL. The different ways in which the oxygen and the copper electronic states hybridize is responsible for the diverse properties of this material that range from novel...

Investigation of superionic states in group-III oxides at European XFEL

Jaromír Chalupský from the Czech Academy of Sciences is researching a theoretically predicted superionic state in oxides such as Al2O3, Ga2O3 or In2O3 at the High Energy Density (HED) instrument. In these materials, the metallic atoms remain as a rigid lattice under extreme conditions, while the oxygen atoms can behave like a liquid. The substances thus can behave as an insulator, a...

Study of ultrafast chiral dynamics of the Vitamin D precursor Ergosterol at European XFEL

Caterina Vozzi from the Consiglio Nazionale delle Ricerche (CNR), Milano, Italy, is researching the steroid ergosterol (C28H44O) at the Small Quantum Systems (SQS) instrument of European XFEL. The molecule is a precursor of vitamin D. When exposed to UV light, it is rapidly converted into vitamin D2. Vozzi is interested in the question of how exactly this process takes place. To do this, she...

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...

Time-dependent measurements of carbon nanoparticle inception at European XFEL

Nanoparticles containing carbon have extraordinary chemical and electronic properties. However, their formation from the gas phase is still poorly understood. The team led by Andrea Comandini from the Centre national de la recherche scientifique (CNRS) in Orléans, France, is investigating the formation of carbonaceous nanoparticles at different temperatures and pressures at the MID experiment...

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...

Lifetime determination of key astrophysical transitions in highly charged ions at European XFEL

Measuring the lifetime of excited states of highly charged neon ions using X-rays at the SQS (Small Quantum Systems) experiment station of the European XFEL in Schenefeld near Hamburg. Dr. Chintan Shah from the NASA Goddard Space Flight Centre, USA, uses the so-called pump-and-probe method in the soft X-ray regime. The novel two-color mode of the SASE3 undulator at the European XFEL...

Single-particle X-ray imaging of phycobilisome light harvesting antenna at high repetition rate

Cyanobacteria are also capable of photosynthesis. However, the chemical processes involved are very difficult to study in a near-natural environment. At the SPB/SFX experiment station of the European XFEL in Schenefeld near Hamburg, the team led by Patrick Konold from Uppsala University, Sweden, is trying to gain an unprecedented insight into the light-harvesting mechanism of...

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...
