Valence XPS structure and chemical bond in Cs2UO2Cl4 [PDF]

open access: yesNuclear Technology and Radiation Protection, 2016
Quantitative analysis was done of the valence electrons X-ray photoelectron spectra structure in the binding energy (BE) range of 0 eV to ~35 eV for crystalline dicaesium tetrachloro-dioxouranium (VI) (Cs2UO2Cl4).

X-ray absorption spectroscopy and actinide electrochemistry: a setup dedicated to radioactive samples applied to neptunium chemistry

open access: yesJournal of Synchrotron Radiation, 2022
A spectroelectrochemical setup has been developed to investigate radioactive elements in small volumes (0.7 to 2 ml) under oxidation–reduction (redox) controlled conditions by X-ray absorption spectroscopy (XAS).

Actinide inverse trans influence versus cooperative pushing from below and multi-center bonding

open access: yesNature Communications, 2023
Actinide-ligand bonds with high multiplicities remain poorly understood. Decades ago, an effect known as 6p pushing from below (PFB) was proposed to enhance actinide covalency. A related effect—also poorly understood—is inverse trans influence (ITI). The

Carbon-sulfur bond strength in methanesulfinate and benzenesulfinate ligands directs decomposition of Np(v) and Pu(v) coordination complexes. [PDF]

open access: yes, 2020
Gas-phase coordination complexes of actinyl(v) cations, AnO2+, provide a basis to assess fundamental aspects of actinide chemistry. Electrospray ionization of solutions containing an actinyl cation and sulfonate anion CH3SO2- or C6H5SO2- generated ...

Quantifying neptunium oxidation states in nitric acid through spectroelectrochemistry and chemometrics

open access: yesFrontiers in Nuclear Engineering, 2023
Controlled-potential in situ thin-layer spectropotentiometry was leveraged to generate visible/near-infrared (VIS/NIR) absorption spectral data sets for the development of chemometric models to quantify Np(III/IV/V/VI) oxidation states in HNO3.

Comparison of actinides and fission products recycling scheme with the normal plutonium recycling scheme in fast reactors [PDF]

open access: yesNuclear Technology and Radiation Protection, 2013
Multiple recycling of actinides and non-volatile fission products in fast reactors through the dry re-fabrication/reprocessing atomics international reduction oxidation process has been studied as a possible way to reduce the long-term potential ...

Recovery of actinides from actinide-aluminium alloys by chlorination: Part I [PDF]

open access: yes, 2011
Pyrochemical processes in molten LiCl–KCl are being developed in ITU for recovery of actinides from spent nuclear fuel. The fuel is anodically dissolved to the molten salt electrolyte and actinides are electrochemically reduced on solid aluminium ...
