A New Method for Exploring the Early Stages of the Crystallization of Small Organic Carboxylic Acids at Constant pH and Temperature and Quantitatively Assessing Additive Effects

Chemistry–Methods, Volume 6, Issue 7, July 2026.
We introduce a titration‐based method to explore the early stages of the crystallization of small organic molecules with carboxylic acid functions in water. It enables the determination of fundamental physicochemical characteristics (pKa values and solubilities) and the quantitative study of prenucleation, nucleation, and early postnucleation stages ...

Dynamics of 137Cs uptake from water to Prussian carp (Carassius gibelio)

Ядерна фізика та енергетика, 2020
The rate constants of 137Cs uptake in Prussian carp (Carassius gibelio) from the water with a potassium content of 2 mg·L-1 at T = 5 °C without feeding (kw = 0.045 ± 0.001 day-1), at T = 12 °C with «clean» feeding (0.046 ± 0.002 day-1) and at T = 22 °C ...

Geochemical alkaline barriers determining radioecological conditions in the Sochi river valley of the Black Sea Coast of Russia

Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2022
Radioecological features of natural environments of the Sochi River valley, one of the largest rivers of the Main Caucasian Range and the Black Sea coast of Russia were studied. Alluvial soils, mosses, and river waters were the subject of investigations.

THE RADIOECOLOGY OF A BEACH [PDF]

Limnology and Oceanography, 1964
The accumulation of fission products, especially the insoluble radionuclides Ru106, Cc144, Zr95, and Nb95, by the fauna and flora on Windscale Beach is affected by the following factors: 1) the particle size and chemical composition of the substratum; 2) wind action on contaminated silt lifting it from near low‐water mark and depositing it near high ...

Radium Speciation in Simulated Digestive Biofluids: Insights from Electrospray Ionization Mass Spectrometry and Thermodynamic Modeling

Analysis &Sensing, Volume 6, Issue 2, March 2026.
Electrospray ionization mass spectrometry (ESI‐MS) combined with thermodynamic modeling provides the first direct characterization of radium speciation in synthetic gastrointestinal biofluids. Free Ra2+ ions predominate with minimal protein binding and negligible EDTA complexation. Crown ethers enable effective Ra complexation.

Inter-Taxa Differences in Iodine Uptake by Plants: Implications for Food Quality and Contamination

Agronomy, 2015
Although iodine is not essential for plants, they take it up readily and, in foodchains, are significant sources of iodine for organisms with an essential requirement for it. During several nuclear accidents radioiodine has been an important component of

Uranium and Neptunium Accumulation by the Byssus of Mytilus galloprovincialis

European Journal of Inorganic Chemistry, Volume 29, Issue 1, January 1, 2026.
Investigation of uranyl(VI) and neptunyl(V) uptake in mussel's byssus by combining in vivo bioaccumulation with ex vivo isotherms. Data highlight the role of DOPA‐rich mfp proteins in binding both actinyl cations and partial Np(V) reduction. Such data link molecular interactions to radionuclide uptake in the framework of marine radioecology.
