Calcium and Multi‐Isotope Constraints on Cation Exchange in Groundwater

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Cation exchange is one of the most important processes in water‐rock interaction in the presence of clay minerals, with a common Ca‐Mg‐Na exchange system. However, systematic verification of Ca isotopes for tracing cation exchange in natural environments is lacking due to overlapping factors, such as dissolution‐precipitation of Ca‐minerals ...

Nanocrystal Quality–Controlled Scintillation in Porous YAG:Ce Aerogels

Advanced Optical Materials, Volume 14, Issue 19, 22 May 2026.
High‐temperature thermal treatment of YAG:Ce nanoscintillator aerogels increases light yield under ionizing radiation by up to eightfold without affecting timing performance. Additionally, low‐temperature atmospheric treatments reversibly modify the cerium oxidation state, revealing strong defect sensitivity and offering new strategies to optimize ...

Towards speciation of organically bound tritium and deuterium: Quantification of non-exchangeable forms in carbohydrate molecules

, 2018
International audienceAn original methodology to quantitatively explore exchangeability of hydrogen isotopes in carbohydrate molecules is proposed. To access the speciation of organically bound hydrogen isotopes, isotopic exchanges were carried out under

New Insights in the Electrochemical Stability of Various Solid Polymer Electrolytes/Layered Positive Metal‐Oxide Electrode Interfaces in Solid‐State Lithium‐Ion Battery

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
In this work, the electrochemical compatibility of a broad range of solid polymer electrolytes with two Ni‐rich nickel–manganese–cobalt cathodes (NMC622, NMC811) is investigated through a hybrid computational and experimental approach. The relative reactivity of NMC811 to NMC622 is demonstrated, as well as the role of Li cations in the electrolyte ...

Metabolism of organically bound tritium

, 1984
The classic methodology for estimating dose to man from environmental tritium ignores the fact that organically bound tritium in foodstuffs may be directly assimilated in the bound compartment of tissues without previous oxidation.

Organically-bound tritium (OBT) dispersion and accumulation in Severn Estuary sediments. Contract RP01034: report to the Food Standards Agency

, 2009
Discharges of tritium from UK nuclear and non-nuclear sites are usually assumed to be in the form of tritiated water (HTO). However, a proportion of HTO may be converted to organically bound tritium (OBT).

Organically bound tritium (OBT) and carbon-14 accumulation in the sediments off the mouth of the Rhône river

, 2019
International audienceWe have studied the recent history of organically bound tritium (OBT) and carbon-14 in suspended organic matter carried by the Rhône from the analysis of two cores collected in the sedimentary cone off the river mouth.

TO JUSTIFICATION OF ORGANICALLY BOUND TRITIUM MONITORING IN NUCLEAR FACILITIES ENVIRONMENT

Problems of Atomic Science and Technology, Ser. Thermonuclear Fusion, 2012
Задачей исследования являлось изучение миграции тритиевых и углеродных соединений в цепочке хранилище радиоактивных отходов — грунтовые воды — (хвойные деревья) водоёмы — питьевая вода. Использован метод последовательной, каскадной фильтрации проб, который позволил разделить органически связанный тритий (ОСТ) от оксида трития НТО.
