Synchrotron Micro‐X‐Ray Fluorescence Elemental Imaging Reveals Zinc Distribution in the Hyperaccumulator Sedum plumbizincicola (Crassulaceae)

Ecological Research, Volume 41, Issue 1, January 2026.
Sedum plumbizincicola is a zinc‐cadmium hyperaccumulator native to China with high potential for use in phytoremediation. Synchrotron micro‐X‐ray fluorescence elemental imaging shows that zinc is localized in the leaf tips, petioles, and nodes with the highest Zn concentrations observed in the epidermis and vascular system of both leaves and stems ...

rf design studies on the 750 MHz radio frequency quadrupole linac for proton-induced x-ray emission analysis

Physical Review Accelerators and Beams, 2019
The proton-induced x-ray emission (PIXE) is the most commonly used ion beam analysis technique. It allows for nondestructive quantitative elemental characterization and is used in a variety of fields, particularly for the diagnosis of cultural heritage ...

Crossing scales and eras: Correlative multimodal microscopy heritage studies

Journal of Microscopy, Volume 301, Issue 1, Page 40-68, January 2026.
Abstract The comprehensive characterisation of complex, irreplaceable cultural heritage artefacts presents significant challenges for traditional analytical methods, which can fall short in providing multi‐scale, non‐invasive analysis. Correlative Multimodal Microscopy (CoMic), an approach that integrates data from multiple techniques, offers a ...

Characterizing Emerging Detector Materials for Low‐Dose X‐Ray Imaging

Advanced Materials, Volume 37, Issue 45, November 13, 2025.
X‐ray medical imaging requires detectors that deliver images at as low as reasonably possible dose. This perspective outlines a universal characterization framework of X‐ray imaging detectors, suitable for both emerging semiconductor and scintillator materials, introduces a novel unified figure of merit that links dose with resolution, and offers an ...

The Pace di Siena and its Gems

Journal of Raman Spectroscopy, Volume 56, Issue 11, Page 1254-1278, November 2025.
For the first time, the gems of the Pace di Siena, a rare en ronde bosse enamel preserved in Arezzo (Italy), have been analyzed using a transdisciplinary approach. The combination of gemmology and Raman spectroscopy has led to the identification of blue sapphires and pink spinels, contradicting previous historical classifications.
