Oxidation of Uranium Dioxide [PDF]

open access: yesJournal of Nuclear Science and Technology, 1974
The oxidation of UO2 was studied by thermogravimetry and X-ray diffraction. It was clarified that the thermal history covering the first stage of the oxidation from UO2 to U3O UO7 significantly influenced the rate of the oxidation of the second stage from U3O7 to U3 O8.

Modern x-ray spectral methods in the study of the electronic structure of actinide compounds: Uranium oxide UO2 as an example [PDF]

open access: yesNuclear Technology and Radiation Protection, 2004
Fine X-ray photo electron spectral (XPS) structure of uranium dioxide UO2 in the binding energy (BE) range 0-~č40 eV was associated mostly with the electrons of the outer (OVMO) (0-15 eV BE) and inner (IVMO) (15-40 eV BE) valence molecular orbitals ...

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

open access: yesAdvanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

ABCABC Stacking‐Enabled Non‐Centrosymmetry 3R‐ZnIn2S4 Nanosheets for Piezocatalytic Uranium Extraction

open access: yesAdvanced Science, EarlyView.
The ABCABC stacking sequence in 2D ZnIn2S4 nanosheets creates intrinsic non‐centrosymmetry, enabling robust piezocatalysis under weak mechanical agitation. The nanosheets achieve a H2O2 yield of 276.7 µmol g−1 h−1 and uranium extraction capacity of 763.2 mg g−1 via a dual mechanism of direct piezoreduction and in situ H2O2 complexation.
