Uranium (U) is of enormous global importance because of its use in energy generation,
albeit with potential environmental legacies. While naturally occurring U is widespread in the …

This review discusses recent advances in the synthesis, characterization and toxicity of
metal oxide nanoparticles obtained mainly through biogenic (green) processes. The in vitro …

Zero-valent iron nanoparticle (ZVI-np) and its graphene composites were prepared and
applied in the removal of uranium under anoxic conditions. It was found that solutions …

This contribution is both a review of different aspects of X‐ray photoelectron spectroscopy
that can help one determine U oxidation states and a personal perspective on how to …

Adding organic electron donors to stimulate microbial reduction of highly soluble U (VI) to
less soluble U (IV) is a promising strategy for immobilizing uranium in contaminated …

The radioecological relevance of actinide particles 1 did not first become a matter of concern
following the nuclear accidents at Fukushima, Chernobyl, or Three Mile Island. Public and …

Adsorption and subsequent reduction of U (VI) on Fe (II)-bearing clay minerals can control
the mobility of uranium in subsurface environments. Clays such as montmorillonite provide …

Reductive immobilization of uranium by the stimulation of dissimilatory metal-reducing
bacteria (DMRB) has been investigated as a remediation strategy for subsurface U (VI) …

This review presents the syntheses and characterizations of size and morphology, as well as
the mechanistic aspects, of metallic oxide nanoparticles synthesized by biogenic processes …

Natural uranium (U) occurs as a mixture of three radioactive isotopes: 238 U, 235 U, and
234 U. Only 235 U is fissionable and makes up about 0.7% of natural U, while 238 U is …
