Ex vivo evaluation of an atherosclerotic human coronary artery via histology and high-resolution hard X-ray tomography
Atherosclerotic arteries exhibit characteristic constrictions and substantial deviations from cylindrical shape. Therefore, determining the artery’s cross-section along the centerline is challenging, although high-resolution isotropic three-dimensional data are available. [...]

Correlative 3D anatomy and spatial chemistry in animal-microbe symbioses: developing sample preparation for phase-contrast synchrotron radiation based micro-computed tomography and mass spectrometry imaging

The three-dimensional (3D) architecture of organs, tissues and cells together with the spatial distribution of specific molecules, both enables and drives the close interactions between hosts and microbes. To image the 3D anatomy and molecular composition of an animal-microbe system at a single cell scale we developed a correlative workflow combining phase-contrast synchrotron radiation based micro-computed tomography (PC-SRμCT) and mass spectrometry imaging (MSI).

20 Hz synchrotron X-ray diffraction analysis in laser-pulsed WC-Co hard metal reveals oscillatory stresses and reversible composite plastification
The lifetime of WC-Co inserts used in cutting processes, such as milling, is limited by millisecond temperature and mechanical pulses, which occur as a result of interrupted tool-workpiece contact, thermal fatigue and wear. In the current work, synchrotron X-ray diffraction (XRD) was used in conjunction with a pulsed laser heating set-up to characterise the time-dependent development of stresses and microstructure in locally irradiated WC-Co inserts coated by chemical vapour deposition with 6.5 and 3.5 μm thick TiCN and α-Al2O3 films, respectively.

Determination of damage mechanisms and damage evolution in fiber metal laminates containing friction stir welded thin foils
Synchrotron tomography was carried out during in-situ tensile tests of fiber metal laminates formed by 3 layers of friction stir welded AlMg4.5Sc0.2 (AA5024) alloy foils and 2 layers of glass fiber reinforced polymer. The aim of these investigations was to identify the damage mechanisms and their sequence during quasi-static loading conditions of the fiber metal laminate as well as to determine microstructural features responsible for tensile damage.

Semantic segmentation of synchrotron tomography of multiphase Al-Si alloys using a convolutional neural network with a pixel-wise weighted loss function
Human-based segmentation of tomographic images can be a tedious time-consuming task. Deep learning algorithms and, particularly, convolutional neural networks have become state of the art techniques for pattern recognition in digital images that can replace human-based image segmentation. [...]

Ultracompact 3D microfluidics for time-resolved structural biology
To advance microfluidic integration, we present the use of two-photon additive manufacturing to fold 2D channel layouts into compact free-form 3D fluidic circuits with nanometer precision. We demonstrate this technique by tailoring microfluidic nozzles and mixers for time-resolved structural biology at X-ray free-electron lasers (XFELs). [...]

A load frame for in situ mechanical testing is developed for the microtomography end stations at the imaging beamline P05 and the high-energy material science beamline P07 of PETRA III at DESY, both operated by the Helmholtz- Zentrum Geesthacht. The load frame is fully integrated into the beamline control system and can be controlled via a feedback loop. [...]

Neither cortical nor trabecular: An unusual type of bone in the heavy-load-bearing lower pharyngeal jaw of the black drum (Pogonias cromis)
Durophagous fish consume a diet based primarily on hard-shelled animals, mainly mollusks. In order to successfully perform this task, they are equipped with an extra set of jaws located in their throat called pharyngeal jaws.Here we present the results of a study of the structure of the bony material of the exceptionally powerful lower pharyngeal jaws (LPJs) of the black drum Pogonias cromis which generate the highest biting forces documented in bony fishes.
