On January 30th, 2020, the WHO declared the recent outbreak of coronavirus disease 2019 (COVID-19), a public health emergency of international concern. It declared that there is an urgent need to improve our understanding of the newly identified virus and its possible future evolution as well as to contain the spread; to develop precise diagnostics and treatment, and to improve the public health response and patient care.
The COVID priority access call continues and is still open in 2021.
Green light for SLS 2.0: The planned upgrade of the Swiss Light Source SLS can proceed; the funding is provided for within the framework of the ERI Dispatch for 2021-2024, which has been approved.
Operando X-ray spectrotomography allows scientists to look inside of functioning chemical reactors. A research team at Karlsruhe Institute of Technology (KIT), at Paul Scherrer Institute PSI and at the European Synchrotron Radiation Facility (ESRF) in France have employed this method successfully.
It is necessary to prepare now for the planned upgrade of the Swiss Light Source SLS. In order to do justice to future research, Alun Ashton is estimating the amount of data that future experiments will produce.
The first experimental observation of three-dimensional magnetic ‘vortex rings’ provides fundamental insight into intricate nanoscale structures inside bulk magnets, and offers fresh perspectives for magnetic devices.
During the past decade, scientists have put high effort to achieve sub-10 nm resolution in X-ray microscopy. Recent developments in high-resolution lithography-based diffractive optics, combined with the extreme stability and precision of the PolLux and HERMES scanning X-ray microscopes, resulted now in a so far unreached resolution of seven nanometers in scanning soft X-ray microscopy. Utilizing this highly precise microscopy technique with the X-ray magnetic circular dichroism effect, dimensionality effects in an ensemble of interacting magnetic nanoparticles can be revealed.
The structural changes of Na3.32Fe2.11Ca0.23(P2O7)2 during several charge discharge cycles is viewed by its powder pattern and selected cell parameter evolution.
Dr. Manuel Guizar-Sicairos, beamline scientist at the cSAXS beamline, was elected as a Fellow Member of The Optical Society (OSA) for seminal contributions to methods and applications of coherent lensless imaging, ptychography, x-ray nanotomography, and new modalities of x-ray microscopy.
In a joint research effort, an international team of scientists lead by Emmanuelle Jal (Sorbonne Université) performed a time-resolved experiment at the FERMI free-electron laser to disclose the dynamic behavior of two magnetic element of a compount material in only one snapshot. The X-ray Optics and Applications group developed a dedicated optical element for this experiment that is usable with two different photon energies (colors) simultaneously.
