Multi-length scale tomography for the determination and optimization of the effective microstructural properties in novel hierarchical solid oxide fuel cell anodes

Multi-length scale tomography for the determination and optimization of the effective microstructural properties in novel hierarchical solid oxide fuel cell anodes

Our parametric study shows that increasing the porosity in the spongy layer beyond 10% enhances the effective transport parameters of the spongy layer at an exponential rate, but linearly for the full anode. For the first time, local and global mass transport properties are correlated to the microstructure, which is of wide interest for rationalizing the design optimization of SOFC electrodes and more generally for hierarchical materials in batteries and membranes.

Precise Cerebral Vascular Atlas in Stereotaxic Coordinates of Whole Mouse Brain

Precise Cerebral Vascular Atlas in Stereotaxic Coordinates of Whole Mouse Brain

Understanding amazingly complex brain functions and pathologies requires a complete cerebral vascular atlas in stereotaxic coordinates. Making a precise atlas for cerebral arteries and veins has been a century-old objective in neuroscience and neuropathology. Using micro-optical sectioning tomography (MOST) with a modified Nissl staining method, we acquired five mouse brain data sets containing arteries, veins, and microvessels. Based on the brain-wide vascular spatial structures and brain re... Read more

X-ray tomography-assisted study of a phase inversion process in ceramic hollow fiber systems – Towards practical structural design

X-ray tomography-assisted study of a phase inversion process in ceramic hollow fiber systems – Towards practical structural design

In this study, a series of alumina hollow fibers have been prepared with varied polymer binder (polyethersulfone, PESf) concentration and new polymer-based internal coagulant (aqueous solution of polyvinyl alcohol, PVA). For the first time, the micro-channels were characterized in 3D using X-ray CT to determine micro-channel densities and diameters in the radial direction, as well as the 2D measurement of the pore size in the sponge-like layer.

Revealing the skeleton of polar dinosaur using synchrotron computed tomography

Revealing the skeleton of polar dinosaur using synchrotron computed tomography

Leaellynasaura amicagraphica was a small, bipedal, herbivorous dinosaur from the Early Cretaceous (~106 million years ago) of Australia within the Antarctic Circle of that time.

Synchrotron scans, and the resulting 3D reconstruction of the skull and post-cranial skeleton, provide a unique view of the morphology of Leaellynasaura, and allows this material to be 3D printed for display.

Exploring hominin and non-hominin primate dental fossil remains with neutron microtomography

Exploring hominin and non-hominin primate dental fossil remains with neutron microtomography

Fossil dental remains are an archive of unique information for paleobiological studies. Computed microtomography based on Xray microfocus sources (X-µCT) and Synchrotron Radiation (SR-µCT) allow subtle quantification at the micron and sub-micron scale of the meso- and microstructural signature imprinted in the mineralized tissues, such as enamel and dentine, through highresolution “virtual histology”. Nonetheless, depending on the degree of alterations undergone during fossiliza... Read more

MIA-Clustering: a novel method for segmentation of paleontological material

MIA-Clustering: a novel method for segmentation of paleontological material

Paleontological research increasingly uses high-resolution micro-computed tomography (μCT) to study the inner architecture of modern and fossil bone material to answer important questions regarding vertebrate evolution. This non-destructive method allows for the measurement of otherwise inaccessible morphology. Digital measurement is predicated on the accurate segmentation of modern or fossilized bone from other structures imaged in μCT scans, as errors in segmentation can result in inaccur... Read more

Investigation of cycling-induced microstructural degradation in silicon-based electrodes in lithium-ion batteries using X-ray nanotomography

Investigation of cycling-induced microstructural degradation in silicon-based electrodes in lithium-ion batteries using X-ray nanotomography

The microstructural degradation of a composite silicon electrode at different stages in its cycle life was investigated in 3D using X-ray nano-computed tomography. A reconstructed volume of 36 μm × 27 μm × 26 μm from the composite electrode was imaged in its pristine state and after 1, 10 and 100 cycles. Particle fracturing and phase transformation was observed within the electrode with increased cycling. In addition, a distinct, lower X-ray attenuating phase was clearly resolved,... Read more

Unilever uses Avizo software to visualize and understand food and detergent structures

Food and detergent products are composed of complex micro structures. With modern microscopic techniques we can make them visible. The microstructure greatly affects macroscopic properties such as appearance, taste, mouth feel and solubility. Making these structures visible and quantifying them is essential to the development of products with optimal product properties. A broad range of imaging techniques is used to visualize microstructure elements at different length scales. For example, X-... Read more

Propagation-based phase-contrast x-ray tomography of cochlea using a compact synchrotron source

Propagation-based phase-contrast x-ray tomography of cochlea using a compact synchrotron source

We demonstrate that phase retrieval and tomographic imaging at the organ level of small animals can be advantageously carried out using the monochromatic radiation emitted by a compact x-ray light source, without further optical elements apart from source and detector. This approach allows to carry out microtomography experiments which – due to the large performance gap with respect to conventional laboratory instruments – so far were usually limited to synchrotron sources. We dem... Read more

Hydraulic properties of porous sintered glass bead systems

Hydraulic properties of porous sintered glass bead systems

In this paper, porous sintered glass bead packings are studied, using X-ray Computed Tomography (XRCT) images at 16μm16μm voxel resolution, to obtain not only the porosity field, but also other properties like particle sizes, pore throats and the permeability. The influence of the sintering procedure and the original particle size distributions on the microstructure, and thus on the hydraulic properties, is analyzed in detail. The XRCT data are visualized and studied by advanced image fil... Read more
