On March 20th, Professor Joachim “Achim” Schnadt joined MAX IV as the interim Science Director in a newly formed role following the reorganisation of the MAX IV Science Division. Joachim comes to MAX IV as the former Head of the Department of Physics at Lund University. He has extensive experience working at MAX-lab during many years, as a synchrotron user, and with instrumentation 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.
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.
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.
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.
MAX IV is making significant societal contributions in terms of record-high scientific productivity. In 2023, the number of publications increased by 51% compared to the previous year, and the number of unique users increased by 31%. Moreover, the number of proposals submitted in the most recent Open Call was higher than ever.
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.
Carbon dioxide, emitted mainly by combustion of fossil fuels, is harmful to the climate and the main reason for increased global warming. Diverting carbon dioxide into hydrogen carriers or chemicals such as methanol, a valuable raw material and energy carrier, is thus highly desired. Supported metal nanoparticle heterogeneous catalysts such as copper on zinc oxide is used for the catalytic conversion of carbon dioxide to methanol. Researchers have now discovered that it is possible to avoid by-products and at the same time make the process more sustainable by adding a small amount of gold to the catalyst.
