Chasing (macro)elements in microinvertebrates: A new methodological approach for quantitative and qualitative analyses of phosphorus by PIXE (Particle‐Induced X‐Ray Emission) applied to glacier tardigrades

Methods in Ecology and Evolution
Microinvertebrates in harsh environments often occupy the highest trophic levels and directly influence the turnover of macroelements. However, the investigation of their body elemental composition is complicated due to their low dry weight or sample ...

Trace Element Analysis in Human Neuroblastoma Cell Spheroids Supplemented With ZnCl2 by Micro‐XRF

X-Ray Spectrometry, Volume 55, Issue 4, Page 545-552, July/August 2026.
ABSTRACT Neuroblastoma, the most common extracranial solid tumor of childhood, is responsible for ~10% of pediatric cancer deaths and has high potential for metastasis. Metals are extremely important in biological processes, and changes in their levels have been correlated with the development of cancerous growth.

Proton beam irradiation induces invisible modifications under the surface of painted parchment

Scientific Reports, 2022
Ion beam analysis plays an important role in cultural heritage (CH) studies as it offers a combination of simultaneous and complementary analytical techniques (PIXE/PIGE/RBS) and spatially resolved mapping functions.

High‐Resolution Elemental Analysis of Neuromelanin‐Containing Organelles in Human Locus Coeruleus

Journal of Neurochemistry, Volume 170, Issue 7, July 2026.
Created in https://BioRender.com. Neuromelanin (NM), a dark metal‐chelating pigment in the brain, has long been of interest for its potential roles in aging and Parkinson's disease. In this study, we explored NM‐containing neurons (NM neurons) in the human locus coeruleus at unprecedented resolution.

Methods to estimate marine functional connectivity: A primer

Ecological Applications, Volume 36, Issue 4, June 2026.
Abstract Organism movement is a key process in the transfer of individuals, genes, functional traits, matter, and energy among habitat patches, at sea and across the land–sea interface. The resulting fluxes, collectively termed marine functional connectivity (MFC), underpin planetary health and an array of ecosystem services.

Recent Developments on PIXE Simulation with Geant4

, 2009
Particle induced X-ray emission (PIXE) is an important physical effect that is not yet adequately modelled in Geant4. This paper provides a critical analysis of the problem domain associated with PIXE simulation and describes a set of software ...

Research Trends on Trace Element Contamination in Brazilian Urban Lentic Ecosystems: Environmental and Policy Drivers

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Lentic ecosystems are vulnerable to contamination by trace elements, which can accumulate and pose risks to aquatic life and human health. In a large, developing country such as Brazil, marked by vast geographic, environmental, and socioeconomic diversity, it is crucial to understand how these factors shape research on this group of ...
