Abstract: Abstract For specimen characterization, X-ray microscopy offers a variety of advantages like non-destructive investigations and reduced preparation effort for the samples. Orientation measurements are possible using diffraction contrast tomography (DCT). However, lateral resolution is lower…

Abstract: Alzheimer's disease (AD) is a neurodegenerative disorder which is characterized by increasing dementia. It is accompanied by the development of extracellular β-amyloid plaques and neurofibrillary tangles in the gray matter of the brain. Histology is…

Abstract: Structural peculiarities of several types of cryptocrystalline diamond varieties: carbonado, impact-related yakutite and cryptocrystalline diamond aggregates from kimberlite were studied using Infrared spectroscopy, X-ray diffraction contrast (DCT—Diffraction Contrast Tomography) and phase contrast tomography (PCT). It…

Abstract: The spatial organization of cardiac muscle tissue exhibits a complex structure on multiple length scales, from the sarcomeric unit to the whole organ. Here we demonstrate a multi-scale three-dimensional imaging (3d) approach with three levels…
