The first magnet series consisting of 112 quadrupole electromagnets for SLS2.0 were measured to high precision using a special home-made rotating coils measurement system. This is an important step forward for the realization of SLS2.0, the upgrade of the Swiss Light Source (SLS) at PSI, and a milestone for the members of the Magnet Section in GFA.

The development of next generation fuel cell membranes based on aromatic hydrocarbon chemistry calls for a new antioxidant strategy to tackle radical induced membrane degradation. Although damage by radicals cannot be prevented, the formed aromatic intermediates can be repaired by a suitable additive. Fuel cell experiments demonstrate that the approach is viable on the device level and that repair is a catalytic mechanism.
Scientists have demonstrated, through magnetic X-ray microscopy, that magnetic skyrmions stabilized in ferrimagnetic heterostructures can be displaced by electrical currents at high velocities, and exhibit low deflection angles, proving that ferrimagnetic skyrmions are good candidates for fast skyrmionic devices.
In situ alloying is an effective method to engineer microstructures of additively manufactured Ti6Al4V3Fe alloys.
Two types of charge order with distinct interplay with superconductivity in the kagome material CsV3Sb5
The kagome metals of the family AV3Sb5, featuring a unique structural motif, harbor an array of intriguing phenomena such as chiral charge order and superconductivity. CsV3Sb5 is of particular interest because it displays a double superconducting dome in the region of the temperature-pressure phase diagram where charge order is still present. However, the microscopic origin of such an unusual behavior remains an unsolved issue. Here, to address it, we combine high-pressure, low-temperature muon spin relaxation/rotation with first-principles calculations. We observe ....
Crossover of high-energy spin fluctuations from collective triplons to localized magnetic excitations in Sr14−xCaxCu24O41 ladder
We studied the magnetic excitations in the quasi-one-dimensional (q-1D) ladder subsystem of Sr14−xCaxCu24O41 (SCCO) using Cu L3-edge resonant inelastic X-ray scattering (RIXS). By comparing momentum-resolved RIXS spectra with high (x = 12.2) and without (x = 0) Ca content, we track the evolution of the magnetic excitations from collective two-triplon (2 T) excitations (x = 0) to weakly- dispersive gapped modes at an energy of 280 meV (x = 12.2)...
The real-world application of this type of quantum computing gets one step closer with a new method to capture errors while qubits are talking to each other.
Insights from the Swiss Muon Source, Swiss Spallation Neutron Source and Swiss Light Source reveal this coveted characteristic in an exotic layered material.
Water management is crucial to the successful cold-start in polymer electrolyte fuel cells (PEFCs). The sudden freeze of supercooled water blocks the reactant gas in the cathode and causes rapid voltage failure. In this work, we statistically evaluated the effects of the gas diffusion layer (GDL) substrate, size, saturation, and the coating loads and methods of hydrophobic polymer on the freezing probability of supercooled water by differential scanning calorimetry (DSC).
