Mechanistic Morphogenesis of Organo-Sedimentary Structures Growing Under Geochemically Stressed Conditions: Keystone to Proving the Biogenicity of Some Archaean Stromatolites?

open access: yesGeosciences, 2019
Morphologically diverse organo-sedimentary structures (including microbial mats and stromatolites) provide a palaeobiological record through more than three billion years of Earth history.

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

open access: yesEcological 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 ...

Cadmium uptake by potato roots disrupts plant ion homeostasis, induces oxidative stress and inhibits plant growth

open access: yesCurrent Plant Biology
In this study, we used an integrated analytical approach to investigate early cadmium (Cd) stress responses in potato (Solanum tuberosum). Plant growth, root tip cell viability, and lipid peroxidation analyses were combined with bulk ionomics, root ...

Crossing scales and eras: Correlative multimodal microscopy heritage studies

open access: yesJournal 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

open access: yesAdvanced 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 ...

PIXE and micro-PIXE studies on the distribution of metal ions in environmental and biological samples

open access: yes, 1998
PIXE--Proton Induced X-ray Emission is a novel and powerful tool for non-destructive multi-element analysis with excellent sensitivity. This technique has been applied to several biological and environmental studies at the University of Arizona.
