The study of uranium oxides at different conditions is of paramount importance in the nuclear
field, especially regarding characterization of the spent nuclear fuel behavior in dry storage …

Although the principal physical behaviour of a material is inherently connected to its
fundamental crystal structure, the behaviours observed in the real-world are often driven by …

Research efforts on the description of the low-temperature magnetic order and electronic
properties of U 3 O 8 have been inconclusive so far. Reinterpreting neutron scattering …

In order to model correctly the corrosion of spent nuclear fuel under disposal conditions, it is
important to understand its behavior in the presence of oxidants. To advance in this …

The crystal structures, phonon spectra, and electronic properties of uranium trioxide (UO 3)
under high pressure have been systematically explored using a particle swarm optimization …

When in contact with oxidizing media, UO2 pellets used as nuclear fuel may transform into
U4O9, U3O7, and U3O8. The latter starts forming by stress-induced phase transformation …

The uranium valence electronic structure in the prototypical undistorted perovskite KUO3 is
reported on the basis of a comprehensive experimental study using multi-edge HERFD-XAS …

The evolution of the uranium chemical state in uranium compounds, principally in the
oxides, is of concern in the context of nuclear fuel degradation under storage and repository …

In this work, stoichiometric U 3 O 7 (ie, UO 2.33) has been prepared, its stoichiometry and
structure confirmed by TGA and XRD, respectively, and its Raman fingerprint described for …

The different structures and behaviors of UO2+ x observed in crystallographic and local
structure measurements were examined by extended X-ray absorption fine structure …
