Quantitative laser-based x-ray fluorescence and particle-induced x-ray emission
New Journal of Physics, 2022 In this work, we demonstrate the feasibility of quantitative laser-based x-ray fluorescence (XRF) combined with particle-induced x-ray emission (PIXE) (called XPIF for x-ray and particle-induced fluorescence) spectroscopy analysis for elemental ...

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 ...

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 ...

Ecological Research, Volume 41, Issue 3, May 2026.Selenium hyperaccumulators are plants able to accumulate over 1000 mg/kg in their shoots while growing in their natural environments. The distribution of selenium in the seeds of the three key hyperaccumulating species was elucidated using X‐ray fluorescence microscopy computed tomography (XFM‐CT). ABSTRACT Selenium hyperaccumulators are plants able to

Archaeometric characterization of Byzantine pottery from Păcuiul lui Soare
Heritage Science, 2019 Archaeometric investigations using OM (optical microscopy) and micro-PIXE (particle induced X-ray emission) were performed on 45 ceramic shards unearthed in archaeological excavations at Păcuiul lui Soare (southeastern Romania) and dated to the eleventh ...

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).
