1 sty 2020 · In the present work, we investigate the crystal structure and elastic properties of metallic uranium using density functional theory (DFT) with a projector augmented wave (PAW) pseudopotential [14].
1 lis 2022 · Radiological and environmental risk assessments of uranium require knowledge of its immediate and long-term behaviour in the soil system. To better understand U (VI) behaviour in contaminated soil, a mesocosm experiment was conducted from 2018 to 2021 by amending soil with U (VI).
23 mar 2022 · Increasing uranium (U) content in soils due to anthropogenic U contamination causes accumulation of U in plants, which greatly increases human health risks. This review identified the diverse...
1 sie 2024 · Uranium is a naturally occurring radionuclide with chemical toxicity, derived from deposits formed through complex processes. In recent years, uranium utilization activities have increased uranium levels in the soil environment, posing serious threats to soil quality, food safety, and human health. Phytoextraction of uranium contamination is ...
26 kwi 2019 · It was found that uranium, introduced into the soil as a solution of 238 UO 2 (NO 3) 2, comprises mainly exchangeable forms with soil components in desert-sandy soil and light and typical sierozems, and in meadow soils, the uranium interaction with soil components results in acid-soluble form.
13 cze 2023 · This review synthesized the available evidence of potential sources of Uranium, remediation techniques, and biogeochemical cycling, and further discussed the impact of soil properties on uranium immobilization based on available literature.
At low temperatures these changes in epitaxy result in dramatic modifications to the behavior of the charge-density wave in uranium. The differences are explained with the current theory for the electron-phonon coupling in the uranium lattice.
