Assessing deposition levels of 55Fe, 60Co and 63Ni in the Ignalina NPP environment

, 2010
Two RBMK-1500 reactor units operated in Lithuania in the 1987–2004 period (one of them was stopped for decommissioning in 2004). This study presents a preliminary investigation of surface deposition density levels of 55Fe and 63Ni in moss samples ...

Contact‐dependent iron uptake from dust revealed by elemental analysis of single Trichodesmium colonies

Limnology and Oceanography, Volume 70, Issue 11, Page 3155-3171, November 2025.
Abstract Aerosol dust deposited on the nutrient‐deprived surface ocean can boost phytoplankton growth and oceanic carbon uptake. Low mineral solubility restricts the biological utilization of dust‐nutrients, thereby benefiting phytoplankton that actively dissolve dust.

CASPER‐AI: Machine Learning Applied to Active Collimation in Monolithic Arrays of SDDs

X-Ray Spectrometry, Volume 54, Issue 6, Page 813-818, November/December 2025.
ABSTRACT Monolithic arrays of Silicon Drift Detectors (SDDs) have advanced X‐ray spectroscopy by providing excellent energy resolution and high rates at near ambient temperatures. Despite these benefits, they are affected by charge sharing (CS), where photogenerated charge clouds spread across adjacent channels.

Mesure de vies moyennes dans le noyau 55Fe par la méthode du parcours de recul

, 1973
La méthode du parcours de recul a été utilisée pour mesurer les vies moyennes de 3 états excités du noyau 55Fe produit dans la réaction 52Cr(α, nγ)55Fe à Eα = 11 MeV. Les résultats (en ps) — τ(931 keV) = 13,4 ± 4, τ(1 316) = 26 ± 3,5, τ(1408) = 69 ± 7,5 —

What Does Iron Mean to an Oligodendrocyte?

Glia, Volume 73, Issue 9, Page 1784-1804, September 2025.
Main Points Iron is essential for oligodendrocyte (OL) biology and myelin production, with deficiencies leading to severe neurological impairments. Understanding iron trafficking in OLs is crucial for developing treatments for dysmyelinating conditions. ABSTRACT Iron is essential for life and plays a key role in multiple fundamental cellular functions.
