Determination of P-V equation of state of a natural clinoptilolite using high-pressure powder synchrotron X-ray diffraction

Andrew C. Strzelecki et al.

Summary: This study characterized the high-pressure behavior of a clinoptilolite zeolite by conducting in situ high-pressure experiments and analyzing the crystal structure. The results showed that the Si/Al ratio and pressure-transmitting media influenced the compressional behavior of the zeolite. These findings are important for understanding the high-pressure behavior of microporous materials and developing geophysical signatures for underground nuclear monitoring.

Induced Ferromagnetism in Epitaxial Uranium Dioxide Thin Films

Yogesh Sharma et al.

Summary: This study investigates the relationship between strain engineering, point defects, and ferromagnetism in actinide epitaxial thin films, and provides new insights into the influence of coupled order parameters on the emergent properties of actinide materials.

Pushing Raman spectroscopy over the edge: purported signatures of organic molecules in fossil animals are instrumental artefacts

Julien Alleon et al.

Summary: The use of Raman microspectroscopy in fossil studies may be misleading, as the features attributed to organic compounds in fossils could actually be instrumental artefacts due to intense background luminescence.

Archaeological significance and chemical characterization of the obsidian source in Kirigamine, central Japan: Methodology for provenance analysis of obsidian artefacts using XRF and LA?ICP?MS

Yoshimitsu Suda et al.

Summary: The study aimed to establish a method for provenance analysis of obsidian artefacts based on chemical compositions by determining the chemical compositions of 13 groups of obsidian sources in the Kirigamine area and proposing discrimination diagrams using WDXRF and LA-ICP-MS analyses. The verification of provenance analyses of obsidian artefacts excavated at the Hiroppara prehistoric site yielded consistent results among the methods used. The discrimination methods described may be applied to further provenance analysis using nondestructive and micro-destructive analyses.

Micro-focus X-ray CT scanning of two rare wooden objects from the wreck of the London, and its application in heritage science and conservation

Kathryn E. Rankin et al.

Summary: Through mu-CT scanning, the study successfully identified the wood types of two wooden objects to the genus level. The conservation treatment used did not obscure the microscopic anatomical features of the objects, recommending that mu-CT scanning should be conducted after conservation when the objects are stable.
