An oxide layer will be formed on the surface of nitrogen-rich uranium nitride (UN2-x) after a long-term exposure to air [3]. The surface composition, electronic structure and microstructure of the oxide layer are studied by using X-ray photoelectron spectroscopy (XPS), Auger electron ...
On the origin of low-valent uranium oxidation state The authors investigate fundamental interactions in low-valent uranium compounds using resonant inelastic X-ray scattering, providing insights into their complex electronic structures and contributing to our understanding of actinide chemistry.

This database provided by the National Institute of Standards and Technology (NIST) contains total energies and orbital eigenvalues for the atoms hydrogen through uranium, as computed in several standard variants of density-functional theory. Data have been generated for atomic electronic structure calcul...

The pseudo-relativistic Hartree–Fock (HFR) method has been exploited for the investigation on the sensitivity of opacity for uranium (U II and U III) to the inclusion of core polarization effects, still weak, in the calculation of atomic data [6] and also of opacity for lowly and moderatel...
Understanding the corrosion of uranium is important for its safe, long-term storage. Uranium metal corrodes rapidly in air, but the exact mechanism remains subject to debate. Atom Probe Tomography was used to investigate the surface microstructure of metallic depleted uranium specimens following polishi...
(C-14). In 1933, the heaviest known naturally-occurring element was uranium having atomic number 92 which existed as isotopes uranium-235 having 92 protons and 143 neutrons (U-235), uranium-236 with 144 neutrons (U-236), uranium 237 with 145 neutrons (U-237) and uranium 238 with 146 ...
