Dr. Manuel Guizar-Sicairos is awarded ICO prize
Dr. Manuel Guizar-Sicairos, beamline scientist at the cSAXS beamline, is the 2019 recipient of the International Commission for Optics (ICO) Prize. The distinction was awarded in the EOSAM conference in Rome.
Imaging strain with high resolution
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.
Wie Katalysatoren altern
Katalysatoren, die in der Industrie eingesetzt werden, verändern über die Jahre ihre Materialstruktur. Mit einer neuen Methode haben PSI-Forschende dies nun auf der Nano-Skala untersucht.
Understanding Why Solid-State Batteries Fail
Researchers from the University of Oxford, the Diamond Light Source and the Paul Scherrer Institut have generated strong evidence supporting one of two competing theories regarding the mechanism by which lithium metal dendrites grow through ceramic electrolytes. A process leading to short circuit at high rates of charge. The X-ray phase-contrast imaging capabilities of the TOMCAT beamline of the Swiss light source allowed researchers to visualize and characterize the growth of cracks and dendrites deep within an operating solid-state battery. The results were published in Nature Materials on April 22, 2021.
Quantifying oriented myelin in mouse and human brain
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.
Magnetic vortices come full circle
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.
Dr. Manuel Guizar-Sicairos elected as Fellow member of The Optical Society (OSA)
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.
Nanowelten in 3-D
Tomogramme aus dem Inneren von Fossilien, Hirnzellen oder Computerchips liefern neue Erkenntnisse über feinste Strukturen. Die 3-D-Bilder gelingen mithilfe der Röntgenstrahlen der Synchrotron Lichtquelle Schweiz SLS dank eigens entwickelter Detektoren und raffinierter Computeralgorithmen.
Kurzfilm eines magnetischen Nanowirbels
Mit einer neu entwickelten Untersuchungsmethode konnten Forschende die magnetische Struktur im Inneren eines Materials mit Nanometer-Auflösung abbilden. Ihnen gelang ein kurzer «Film» aus sieben Bildern, der erstmalig in 3-D zeigt, wie sich winzige Wirbel der Magnetisierung tief im Inneren eines Materials verändern.
