In the field of radioactive wastewater treatment associated with environmental remediation, a
big challenge is to achieve the simultaneous elimination of toxic metal cations and metallate …

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 …

The origins and near-surface distributions of the~ 250 known uranium and/or thorium
minerals elucidate principles of mineral evolution. This history can be divided into four …

Radiation induced dissolution of uranium dioxide (UO2) nuclear fuel and the consequent
release of radionuclides to intruding groundwater are key-processes in the safety analysis of …

The extensive studies of used fuel dissolution inside a failed nuclear waste container have
been reviewed. The primary controlling factor is the redox condition set at the fuel surface by …

A novel adsorbent poly (methacrylic acid)-grafted chitosan/bentonite (CTS-g-PMAA/Bent)
composite was prepared through graft copolymerization reaction of methacrylic acid and …

The occurrence and binding energies of the U6+, U5+ and U4+ bands in the U 4f7/2 peak of
19 uranyl minerals of different composition and structure were measured by XPS. The …

The long-term stability of biogenic uraninite with respect to oxidative dissolution is pivotal to
the success of in situ bioreduction strategies for the subsurface remediation of uranium …

U (VI) doped hematite was synthesized and exposed to two different organic reductants with
E 0 of 0.23 and 0.70 V. A combination of HAADF-TEM and EXAFS provided evidence that …

The influence of trivalent dopants (rare-earths, RE) on the structure, composition and
electrochemical reactivity of UO 2 has been investigated using scanning electron …
