Summary: Using phase-contrast enhanced synchrotron micro-tomography, researchers can capture the complex 3D organization of Achilles tendon microstructure despite the influence of various factors on image quality. The study suggests that traditional invasive sample preparations like fixation and embedding are not necessary for studying tendon collagen fibers. Instead, high-quality images capturing the complex 3D organization of tendon fibers can be obtained from fresh frozen samples in conditions close to natural.

Summary: The chemical study of materials from natural history and cultural heritage presents challenges due to their complexity and non-reproducibility, but also offers innovative approaches for historical information. Synchrotron methods have been crucial in studying heritage objects, providing speciation information and high-resolution imaging. These developments have paved the way for novel approaches in characterizing ancient and historical materials, with implications for machine learning methods and related fields beyond heritage studies.

Summary: The characterisation of lime mortars is crucial for the conservation and repair of ancient buildings. The pore structure, influenced by manufacturing processes, recipes, and technical expedients, plays a significant role in the strength and durability of mortars. Fermenting organic matter in water and adding it to lime mixture has shown promising potential for improving workability and mechanical performance. The use of high-resolution synchrotron radiation computed microtomography (SR-mu-CT) proves to be an effective tool for studying the contribution of organically fermented water in lime mortars and understanding the impact on pore structure and mechanical properties.

Summary: In this study, the microstructural evolution of a non-reactive porous model food (sponge cake) during freezing was investigated using synchrotron X-ray microtomography (mu-CT) and cryo-scanning electron microscopy (Cryo-SEM). Different freezing rates impacted the ice formation and location, volume fractions of each phase, as well as ice shape characteristics in the samples. The image analysis method based on grey level effectively segmented the air, ice, and starch phases in the frozen samples.

Summary: Oxide facies gold deposits are characterized by high Au-tenor free-milling gold nuggets, with an active gold geochemical cycle during the transition from sulphide- to oxide facies correlated with the formation of iron oxide-rich gossans. In a specific area in Tanzania, surficial gold occurrences hosted by gossanous outcrops provide an ideal natural laboratory for studying supergene gold enrichment processes. Studies have shown that elongate supergene gold particles form interconnected 3-D networks within the developing gossan, with a possible crystallographic control on supergene gold precipitation.

Summary: Interpretation of chemical zoning within igneous minerals is crucial in petrologic studies. 2D slices of 3D mineral systems often lead to a loss of zoning information, making it challenging to infer 3D geometries. Computed X-ray microtomography provides a high-resolution method to assess 3D zoning in minerals, particularly using sanidine with variations in Ba as a marker. The findings in this study have important implications for methodologies that rely on the interpretation of chemical zoning within minerals.

Summary: The effectiveness of several X-ray computer tomography techniques for studying commercial batteries is demonstrated in this paper. General guidelines are provided for selecting suitable imaging equipment and parameters for investigations of lithium-ion batteries at different length scales. Safety mechanisms, manufacturing inconsistencies, defects, and inhomogeneity in batteries are illustrated and quantified. The relationship between beam energy, sample-detector distance, and contrast retrieved from attenuation and phase shift is examined using Synchrotron XCT.

Summary: The study found that both synchrotron microbeam radiation therapy (S-MRT) and synchrotron broad-beam (S-BB) therapy can prolong the survival of mice, but mice in the S-MRT group developed severe pulmonary edema. Postmortem examination revealed that mice in the S-MRT group had smaller tumor volume and did not show any decline in health, while mice in the S-BB group developed pulmonary fibrosis.

Summary: This study investigated the use of a human Thiel-embalmed temporal bone for generating accurate and complete data sets with micro-CT, as well as the effects of solid iodine-staining on visualization and segmentation of middle ear structures. The results showed that micro-CT imaging accurately represented the entire anatomy of the temporal bone, while iodine staining significantly improved the contrast of soft tissues and enabled detailed 3D modeling of the middle ear structures.

Summary: Microbeam radiation therapy (MBRT) is a safe alternative treatment for muzzle tumors in pets, according to a preclinical study. The study examined the effects of microplanar beamlets on the muzzle of rabbits and found that no radionecrosis occurred in facial bones, but high doses of radiation caused caries-like damage to incisor teeth. The study suggests that MBRT can be used to treat muzzle tumors without causing significant damage to normal teeth, bone, and soft tissues if the radiation is controlled within specific dose limits.

Summary: Recent fossil shell mining in the Orlando area of Orange County, Florida has revealed two new species of the ellobioid genus Carychium. The well-preserved shells were examined using high-resolution X-ray tomography to determine their taxonomic classification. Comparison with existing and fossil species of Carychium from different regions allowed the identification of Carychium floridanum and Carychium nashuaense sp. nov. from fossil shells dating back to the Early Pleistocene. This study provides important insights into the fossil record of Carychium in the SE USA.

Summary: The mammalian pulmonary vasculature is composed of functionally and morphologically heterogeneous compartments. However, local changes in these compartments may be masked by the overall heterogeneity of the lung structure. In this study, a method was employed to classify segments of the pulmonary arterial tree into homogeneous groups, allowing for the identification of morphological differences between disease and control groups. The method achieved higher precision in morphological studies compared to a common, global analysis approach.
