Investigation of the porosity of L/LL4 ordinary chondrite Bjurböle using synchrotron radiation microtomography and scanning electron microscopy: Implications for parent body evolution

Hydrothermal Carbonization and Pyrolysis in Wetland Engineering: Carbon Sequestration, Phosphorus Recovery, and Structural Characterization of Willow-Based Chars with X-Ray Μ-Computed Tomography

“…Using X-ray µ-CT with a voxel resolution of 1.14 μm, Rasa et al [53] identified willow pyrochar's pore diameters between 5-25 μm to improve water retention in clay soils. Soini et al [54] argued that better than the equivalent diameter, the Feret diameter is a more accurate value, capable of handling irregular shapes to determine the diameters of pores. The Feret diameter measures the size of an object in a specific direction, determined by the distance between two parallel planes that bound the object perpendicular to that direction.…”

“…When applied to projections of a threedimensional object onto a two-dimensional plane, this diameter is defined as the distance between two parallel tangential lines. However, high computing power is required when dealing with complex 3D-structures [54].…”

Combined Neutron and X‐Ray Tomography—A Versatile and Non‐Destructive Tool in Planetary Geosciences

“…XCT is a relatively easily accessible technique, as it can be performed both with laboratory-based machines, which are now available in many research institutions worldwide, and at synchrotron sources for imaging with higher spatial resolution (Cnudde & Boone, 2013;Hanna & Ketcham, 2017;Hezel, Elangovan, et al, 2013). Over the last two decades, XCT of planetary materials has contributed to major advances in planetary science, providing insight into the 3D mineralogy and deformation textures of meteorites (e.g., Alwmark et al, 2011;Hanna et al, 2022;Hezel, Friedrich, & Uesugi, 2013;Kadlag et al, 2023;Krzesińska, 2011;Lemelle et al, 2004;Soini et al, 2023), asteroid particles from Hayabusa (Tsuchiyama et al, 2013), lunar soil samples (the Apollo Next Generation Sample Analysis; Gross et al, 2023) and some terrestrial impactites, such as impact breccias from the Bosumtwi, the Kara, and the Ries impact structures, and also a Muong Nong-type tektite (Koeberl et al, 2002;Zubov et al, 2021).…”
