Spintronics technology has taken a step forward with new experimental evidence of parallel spin-momentum locking in chiral materials. Results from the spin branch of the Bloch experiment station contributed to the discovery.
The dawning of new interpretation for RIXS spectra
In a recent study at Veritas beamline, researchers from Uppsala University in Sweden observed parity-forbidden transitions to electronic states in an oxygen molecule due to interference analogous to Young’s double split experiment (YDSE). The findings, published in Science Advances, may change the way spectral data is interpreted for RIXS experiments and refine the conventional wisdom in synchrotron science for the interplay of photons with the dynamics of atomic nuclei in molecules.
xrdPlanner: a new, versatile beamtime planner
Planning and preparing for a beamtime experiment at synchrotron facilities can be challenging and time-consuming, especially for first-time users and students with no previous experience. The team at DanMAX, MAX IV, developed xrdPlanner, an open-source software package to aid the preparation of powder X-ray diffraction and total scattering experiments at synchrotron light sources.
Gut bacteria and atomic structure tell the story of universal blood
In clinical practice it is well established that type O blood, which lacks A and B antigens on the red blood cells, can be safely used in universal blood transfusions for any ABO blood group. Serious or even fatal immune reactions may occur if one receives incompatible blood from a donor. How might we mitigate the risks for low donor supply or unusable blood in emergencies? Research groups from the Technical University of Denmark (DTU) and Lund University now report in Nature Microbiology, an enzymatic conversion method to create ABO-universal blood, a major leap towards human blood that could potentially enable live-saving blood donations to anyone, without negative immune response or the need for matched donor-recipient blood types. Data for the structural determination of key enzymes used in conversion of the ABO-universal blood was collected at MAX IV’s BioMAX beamline.
Nano-focused X-rays aid integrated circuit development
A modern chip contains billions of transistors. The size of individual features is just a couple of tens of nanometres. With decreasing size follows increased demands on material control and characterisation down to the atomic scale. The nano-focused X-ray beam at beamline NanoMAX prove to be a useful tool for investigating electromigration, a significant cause of failure in on-chip interconnects.
A unifying theory of superconductivity: Finding common symmetry
A global goal of physics is greater knowledge of the mechanism of superconductivity. A research group from China and the United Kingdom recently reported in Nature Physics the pairing symmetry of iron-based superconductor KFe2As2, which contains only hole pockets on the fermi surface. The result, which includes measurements at BLOCH beamline, brings science closer to a unified theory of unconventional superconductivity for iron-based materials.
Ionic liquids key to sustainable energy storage
High-capacity energy storage systems are an important part of the renewable energy transition and can be realised using RTILs, room temperature ionic liquids, as electrolytes.
A research team from University of Tartu, Estonia, recently used beamline FlexPES to study the stability of RTILs for such applications.
Microgel properties in X-ray spotlight
Microgels are versatile soft colloids used for example as pharmaceutical carriers or for sensing applications. In a recent study, X-ray methods are used to uncover details about their properties to open ways for further optimisation.
Nanoscience for clean water at ForMAX supported by ReMade@ARI
Alejandro Cortés Villena and Alessandro Ciccone from Institute of Molecular Science in Valencia are using the ForMAX beamline as part of their research supported by ReMade@ARI, a collaboration project focusing on Circular Economy. They are studying carbon-based nanomaterials that are going to be used for enabling cleaning of contaminants in water with the help of sunlight through photocatalysis.
Research done at MAX IV contributes to CIGS solar cell world record
A recent publication from Uppsala University reported a world record for efficiency for a CIGS solar cell. Nano X-ray Fluorescence imaging was done at beamline NanoMAX. With this method, the researchers can detect which elements are present in the sample on the nanometre scale. By scanning the sample, they can acquire an image with a
