Comparative experimental observations of cement with a flow channel subject to CO2-saturated brine flow by micro-CT scanning and CT image post processing.
Understanding CO2-induced micro-structural changes at the imperfections in wellbore cement is vital for assessing the risk of CO2 leakage through wellbore cement under geologic CO2 storage (GCS) conditions. To investigate the evolution of a flow channel width in cement under GCS conditions and the influence of effective stress and fl... Read more

Li metal is considered as the most important negative electrode active material for Li-based batteries because of its high theoretical specific capacity of 3860mAh g-1, which is an order of magnitude higher than the currently used graphite, and by being the most electropositive metal. When coupled with high-capacity cathodes, either Li insertion materials or conversion chemistries, or applied in a solid-sate configuration, a leap in energy density can be obtained. The main challenge in the di... Read more

In this study, the researchers investigated the compressive failure mechanisms in flax fiber composites, a promising eco-friendly alternative to synthetic composite materials, through both numerical simulations and experimental analysis. They examined the reasons behind the low compressive strength in comparison to tensile strength, focusing on the compressive-to-tensile strength ratio. A novel thermodynamically consistent continuum damage micromechanics model was introduced to capture the ev... Read more

This study provides a comprehensive review of tortuosity and its impact on the transport properties of porous media. It discusses the classical theories and equations related to tortuosity for flow, conduction, and diffusion. The study also highlights the evolution of these theories and their connection to methodologies such as tomography and 3D image analysis. In order to clarify the topic, a new classification scheme and nomenclature for different types of tortuosity are proposed. The study... Read more

Three-Dimensional Architecture of Glomerular Endothelial Cells Revealed by FIB-SEM Tomography
Focused-ion beam-scanning electron microscopic (FIB-SEM) tomography enables easier acquisition of a series of ultrastructural, sectional images directly from resin-embedded biological samples. In this study, to clarify the three-dimensional (3D) architecture of glomerular endothelial cells (GEnCs) in adult rats, we manually extracted GEnCs from serial FIB-SEM images and reconstructed them on an Amira reconstruction software. The luminal and basal surface structures were clearly visualized in ... Read more

Multiscale reconstruction of various vessels in the intact murine liver lobe
The liver contains a variety of vessels and participates in miscellaneous physiological functions. While past studies generally focused on certain hepatic vessels, we simultaneously obtained all the vessels and cytoarchitectural information of the intact mouse liver lobe at single-cell resolution. […] providing a technology roadmap for studying the fine hepatic vascular structures and their spatial relationship, which will help research into liver diseases and evaluation of medical effi...

Three-dimensional imaging of microstructural evolution in SEM-based nano-CT
Scanning electron microscopy (SEM) is a powerful and versatile technique for materials characterization and present in many laboratories. The integration of an X-ray target holder and detector allows expanding the modalities of SEM by X-ray imaging. These little hardware adaptations enable radiography ... Read more

The Ebola virus VP40 matrix layer undergoes endosomal disassembly essential for membrane fusion
Ebola viruses (EBOVs) assemble into filamentous virions, whose shape and stability are determined by the matrix viral protein 40 (VP40). Virus entry into host cells occurs via membrane fusion in late endosomes; however, the mechanism of how the remarkably long virions undergo uncoating, including virion disassembly and nucleocapsid release into the cytosol, remains unknown. Here, we investigate the structural architecture of EBOVs entering host cells and discover that the VP40 matrix disassem... Read more

Recycling spent lithium-ion batteries (LiBs) guarantees the conservation of important metal resources by reducing demands on raw supply and offsetting the energy and environmental costs associated with its manufacture. Employing a molten salt as a solvent for extraction affords a much greener and simpler route to metal recovery by electrochemical means. The current mechanistic understanding of the electrochemical recovery of metals in molten salts needs to be improved for the process to be op... Read more

The internal skeleton of the nasal cavity is sporadically and often incompletely described for many marsupial species and mammals in general. Here, I provide an anatomical survey of the ethmoid in the skulls of adult marsupials based on examination of computed tomography (CT) imagery of 29 taxa representing all the major extant groups of marsupials. (…) I compared ecological data with the number of ecto- and endoturbinals as a preliminary test to determine whether some of the interspec... Read more

X-ray computed tomography (XCT) has been shown to reveal the true extent of ductile damage below the fracture surface of failed test specimens, which is often significantly underestimated when probed using 2D serial sectioning techniques and a microscope, since a single plane of material may only exhibit only a handful of resolvable voids.
In contrast XCT offers the capability to generate large datasets consisting of hundreds, if not thousands, of individually resolvable voids, where e... Read more

Despite advances in imaging, image-based vascular systems biology has remained challenging because blood vessel data are often available only from a single modality or at a given spatial scale, and cross-modality data are difficult to integrate.
Therefore, there is an exigent need for a multimodality pipeline that enables ex vivo vascular imaging with magnetic resonance imaging, computed tomography and optical microscopy of the same sample, while permitting imaging with complementary c... Read more

Among natural cellular materials, pomelo peels, having a foam-like hierarchical microstructure, represent an ideal model for developing materials with high energy absorption efficiency. In this work, by combining X-ray tomographic imaging technique and digital volume correlation (DVC), in-situ stepwise uniaxial compression tests were performed to quantify the internal morphological evolution and kinematic responses of pomelo peel samples during compression.

The complex mechanical response of open-cell foams depends strongly on the hierarchy of length scales inherent in them, from engineering-part scale to the ligament scale through the grain scale down to the crystal-lattice scale. A first step toward understanding and predicting the coordinated mechanical response across le... Read more

During the last decades, X-ray (micro-)computed tomography has gained increasing attention for the description of porous skeletal and shell structures of various organism groups. However, their quantitative analysis is often hampered by the difficulty to discriminate cavities and pores within the object from the surrounding region. Herein, we test the ambient occlusion (AO) algorithm and newly implemented optimisations for the segmentation of cavities (implemented in the software Amira). (... Read more

Multi-modal plasma focused ion beam serial section tomography of an organic paint coating
Pigment distributions have a critical role in the corrosion protection properties of organic paint coatings, but they are difficult to image in 3D over statistically significant volumes and at sufficiently high spatial resolutions required for detailed analysis. Here we report, for the first time, large volume analytical serial sectioning tomography of an organic composite coating using a xenon Plasma Focused Ion Beam (PFIB) combined with secondary electron imaging, energy dispersive X-ray (E...
