In an exciting collaboration, Nick Phillips, a PSI Fellow at the cSAXS beamline, reveals nanoscale lattice distortions created by invisible defects in fusion reactor armor. This work develops the current understanding of how the smallest, but most prevalent defects, generated during neutron irradiation behave. The novel Bragg ptychographic approach published in Nature Communications paves the way for fast, robust, 3D Bragg ptychography.
PSI researchers win the international Innovation Award on Synchrotron Radiation for 3D mapping of nanoscopic details in macroscopic specimens, such as bone.
Hard X-ray cryo-tomography scanning of retina from healthy and inherited blindness specimen paves the way for correlative analysis after imaging at the cSAXS beamline.
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 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.
Catalysts used in industry change their material structure over the years. Using a new method, PSI researchers have now studied this on the nanoscale.
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.
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, 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.
