Trace Element Analysis of Cancerous and Non-cancerous Breast Tissues of African Women in Southwest Nigeria Using Particle-Induced X-ray Emission Technique

Breast Cancer: Basic and Clinical Research, 2019
In this study, we applied particle-induced X-ray emission (PIXE) spectroscopy to investigate the levels of trace elements in breast tissues and whole blood (cancerous and non-cancerous) of selected African women in Ile-Ife, Southwest Nigeria.

STRAS: a new high-time-resolution aerosol sampler for particle-induced X-ray emission (PIXE) analysis [PDF]

Atmospheric Measurement Techniques
The joint use of hourly resolution sampling and analyses with accelerated ion beams such as with the particle-induced X-ray emission (PIXE) technique has allowed the measurement of hourly temporal patterns of particulate matter (PM) composition at many ...

Sourcing carnelian beads from the ancient Mesopotamian site of Kish, Iraq, 2450–2200 BCE: Stylistic, technological and geochemical approaches

Archaeometry, Volume 68, Issue S1, Page S22-S37, April 2026.
Abstract Trade between Mesopotamia and the Indus Civilization is studied through the analysis of Early Dynastic III Period (2600–2350 BCE) carnelian beads from the site of Kish, Iraq. Morphological and technological features of the beads are compared with beads from the Indus region.

Broadening the Workflow for Synchrotron‐Based X‐Ray Fluorescence and X‐Ray Absorption Spectroscopy Imaging of Low‐Abundance Cellular Metals

Chemistry–Methods, Volume 6, Issue 3, March 2026.
We present an accessible plunge‐freezing and freeze‐drying workflow for preparing adherent mammalian cells for synchrotron‐based nanofocused X‐ray fluorescence (XRF) microscopy and X‐ray absorption spectroscopy (XAS), enabling sub‐micron mapping of metal distribution and chemical speciation.

Spectroscopic techniques in the investigation of extraordinary medieval Polish coins: Revealing the presence of hidden cores

Nukleonika
Cross denars, frequently found in Polish hoards, were traditionally thought to be Ag coins with some Cu content. This study investigates the possibility of a hidden Cu core beneath the Ag or Ag–Cu surface of these coins. It raises questions about whether

Three‐Decade Dust Climatology and Trend (1988–2022) From Ground Monitoring Over the Western United States

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 4, 28 February 2026.
Abstract Airborne dust exerts myriad effects on climate, weather, human health and safety. In this study, 35‐year records (1988–2022) of ground aerosol observations were analyzed to identify windblown dust events from 18 Interagency Monitoring of Protected Visual Environments (IMPROVE) stations over the western United States (US).

Application of PIXE for the elemental analysis of coins [PDF]

, 2020
Particle Induced X-ray Emission (PIXE) is a nondestructive Ion Beam Analysis (IBA) technique that can be used for identifying elements in a sample. In PIXE, the radiation emitted by electron state changes is measured, after which emissions are recorded ...
