Milestone in predicting core plasma turbulence: successful multi-channel validation of the gyrokinetic code GENE

On the basis of several recent breakthroughs in fusion research, many activities have been launched around the world to develop fusion power plants on the fastest possible time scale. In this context, high-fidelity simulations of the plasma behavior on large supercomputers provide one of the main pathways to accelerating progress by guiding crucial design decisions. When it comes to determining the energy confinement time of a magnetic confinement fusion device, which is a key quantity of interest, gyrokinetic turbulence simulations are considered the approach of choice – but the question, whether they are really able to reliably predict the plasma behavior is still open. The present study addresses this important issue by means of careful comparisons between state-of-the-art gyrokinetic turbulence simulations with the GENE code and experimental observations in the ASDEX Upgrade tokamak for an unprecedented number of simultaneous plasma observables

Trait emotional intelligence in competitive sports: are there differences in dimensions of emotional intelligence when comparing different sports?

Emotional intelligence (EI) is a determinant of athletic performance. Since each sport has its own psychological requirements, individual EI dimensions could have different relevance for athletic performance. This study investigated EI variations among athletes participating in 48 different sports, considering the specific emotional challenges faced by athletes in competitive sports using the appraisal theory of emotions. A total of 605 athletes (44.3% female) actively engaged in competitive sports completed the Trait Emotional Intelligence Questionnaire via an online survey. Analyses of variance, controlling for age and gender, revealed no overall link between EI and different sports. However, the dimension of self-control within EI demonstrated significant relevance among athletes in contact sports, sports with a higher degree of control over environmental conditions, and sports with direct referee intervention. On the other hand, the dimension of well-being within EI exhibited significant relevance for athletes in individual sports. Thus, this study suggests that investigating appraisal processes in athletes’ emotional experiences, particularly focusing on the self-control dimension of EI, useful for future research in the field of EI

NMR of a single nuclear spin detected by a scanning tunnelling microscope

We detect a single spin nuclear magnetic resonance (NMR) by monitoring the intensity modulations of a selected hyperfine line in the electron spin resonance (ESR) spectrum. We analyse the power spectrum of the corresponding hyperfine intensity and obtain the nuclear magnetic resonance (NMR) spectrum. Our process also demonstrates ionization of a molecule with the bias voltage of a Scanning Tunnelling Microscope (STM), allowing detection of NMR even in molecules that are non-radical in their neutral state. We have observed this phenomenon in four types of molecules: toluene, triphenylphosphine, TEMPO and adenosine triphosphate (ATP) showing NMR of $^{1}$H, $^{13}$C, $^{31}$P and $^{14}$N nuclei. The spectra are detailed and show signatures of the chemical environment, i.e. chemical shifts. A theoretical model to account for these data is outlined

A Mature Tool to Address New Challenges: Harnessing Coordination Chemistry for The Sustainable Copper Recovery from Industrial and E‐Waste in The Age of Energy Transition

Copper is arguably one of the most strategic metals for the energy transition, particularly in the shift from fossil fuel-based engines to sustainable and renewable energy sources, with related and broader electrification efforts. While global copper mineral resources are far from depleted, their uneven distribution poses significant supply risks, especially in regions like Europe. In 2023, the European Union (EU) recognized this risk by designating copper as a strategic raw material (SRM), highlighting the need for innovative copper recovery processes. Copper recovery from industrial and electronic waste has been approached through various methods, primarily categorized into pyrometallurgy and solvo- and hydrometallurgy. The latter offers greater tunability and potential for sustainability, particularly when leveraging coordination chemistry. This review focuses on the most promising hydrometallurgical processes for copper recovery from industrial and e-waste (i. e., electronic waste), with a special emphasis on the role of coordination chemistry in supporting these methods. We posed particular focus on the adaptability and versatility of the coordination chemistry-based processes to the highly heterogenous composition of the copper-containing wastes
