Together with international colleagues, PSI researchers have now been able to make correlated metals more readily usable for applications in superconductivity, data processing, and quantum computers.
Full-field X-ray absorption tomography reveals the chemical structure of defects in metal-organic frameworks
Cryo-full-field XANES computed tomography was used to visualize the presence and distribution of a second coordination polymer of reduced copper coordination within defect-engineered HKUST-1 MOF crystals. Observations encourage a revisitation of the structure-property relationships of defect-engineered MOFs.
Imaging strain in crystalline materials with high resolution can be a challenging task. Researchers demonstrate an original use of X-ray ptychography for this purpose: ptychographic topography.
Scientists decode the structure of the enzyme responsible for the ethane fixation by – beside others – using the SLS.
Catalysts used in industry change their material structure over the years. Using a new method, PSI researchers have now studied this on the nanoscale.
Crystal structure of SARS-CoV-2 Orf9b in complex with human TOM70 suggests unusual virus-host interactions
In a study published in Nature Communications, researchers at the NHC Key Laboratory of Systems Biology of Pathogens in Beijing, China, in collaboration with the Paul Scherrer Institut characterize the interactions of SARS-CoV-2 orf9b and human TOM70 biochemically, and they determine the 2.2 Å crystal structure of the TOM70 cytosolic domain with a bound SARS-CoV-2 orf9b peptide.
Microrobots, materials with shape memory, and better particle accelerators are made possible through the exploration of magnetism at PSI.
Myelin 'insulates' our neurons enabling fast signal transduction in our brain. Myelin levels, integrity, and neuron orientations are important determinants of brain development and disease. Small-angle X-ray scattering tensor tomography (SAXS-TT) is a promising technique for non-destructive, stain-free imaging of brain samples, enabling quantitative studies of myelination and neuron orientations, i.e. of nano-scale properties imaged over centimeter-sized samples.
Researchers at Goethe University Frankfurt, in cooperation with the PSI have probably discovered another, previously unknown mechanism of action of the antiviral remdesivir.
