Bacterial influence on uranium oxidation reduction reactions : implications for environmental remediation and isotopic composition
… influence on the chemistry and speciation of uranium has some important impacts on the environment, and can be exploited usefully for the purposes of environmental remediation of uranium waste contamination. It is important to understand both from a scientific and environmental perspective how …

Modeling the oxidation surface reaction on uranium metal
The chemistry of γ-uranium is of primary importance for metal-fueled fast reactors which have been suggested as a key component of future fuel cycles. However, despite the fascinating chemistry of uranium, experimental difficulties have limited the scope of studies until recent years when …

Ion Beam Synthesis and Irradiation for Si-Based Photonic Materials and Nuclear Waste Management
… while aqueous conditions promoted surface oxidation, with increased U(VI) compared to unirradiated UO₂. These findings suggest that prolonged exposure of used fuel to residual alpha radiation within a sealed used fuel container poses no additional safety concerns as long as containment …

Chromium and uranium isotopic exchange kinetics and isotope fractionation during oxidation of tetravalent uranium by dissolved oxygen
Chromium (Cr) and Uranium (U) isotopes (53Cr/52Cr and 238U/235U ratios) are very powerful new geochemical tools in environmental remediation and paleoredox reconstruction studies. Correctly interpreting Cr and U isotopic compositions in groundwater and sed- imentary rock samples requires thorough …
