Global Biogeochemical Cycles, Volume 40, Issue 5, May 2026.Abstract Atmospheric deposition of micro‐nutrients like Fe has been shown to be important for ocean biogeochemistry. The largest source of atmospheric Fe and other elements (e.g., Ca, Al, Si, and Ti) is desert dust, although there are significant non‐dust sources in some regions (e.g., combustion, sea salts, volcanoes). However, past estimates of these

APPLICATION OF MICRO-PIXE ANALYSIS TO INVESTIGATE TRACE ELEMENTS IN DECIDUOUS TEETH ENAMEL
, 2010 The early life environment has widespread consequences for later health and disease. To prevent the disease in later life, the assessment of fetal environment is very important. In Japan, birthweight has fallen rapidly during recent two decades.

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

, 2001 Raman spectroscopy can be applied to characterise the chemical composition of an atherosclerotic plaque in vivo. In the near future this technique may become available for use in (coronary) arteries of living patients. For this moment, Raman spectroscopy

XRF, PIXE and SR-XRF studies on prehistoric gold provenance
UISPP Journal, 2019 One of the most efficient methods to authenticate ancient gold artifacts and find their provenance is to identify trace elements – Sn, Sb, Te, PGA (especially Pt, Ir-Os, Pd), considered as “fingerprints” of a geological source, as ancient metallurgy ...

Influence of Root‐Applied Glutathione on Nickel Uptake and Distribution in Brassica Roots
Ecological Research, Volume 41, Issue 3, May 2026.This study indicates that exogenous glutathione (GSH) applied to the roots inhibits nickel (Ni) uptake and its translocation to the shoots in hydroponically grown Brassica napus. Micro‐PIXE imaging further revealed that GSH reduces Ni accumulation near the stele, indicating inhibition of Ni radial transport toward the vascular tissues.

Advanced Science, Volume 13, Issue 8, 9 February 2026.This study presents a novel microscopic imaging system capable of rapid, section‐free scanning of irregular tissue surfaces, delivering high sensitivity for detecting cancer cell clusters during intraoperative tumor margin assessment. Abstract Rapid and accurate intraoperative examination of tumor margins is crucial for precise surgical treatment, yet ...

PLoS ONE, 2015 In the Mediterranean, the island dwarf megafaunas became extinct around the end of the Pleistocene, during a period of rapid and global climate change. In Cyprus, this coincided with the first human presence on the island, as attested by the rock shelter
