Abstract Plutonium (IV) and (III) ions in nitric acid solution readily form insoluble precipitates
with oxalic acid. The plutonium oxalates are then easily thermally decomposed to form …

The modification of CeO2 properties by means of aliovalent doping is investigated within the
ab initio density functional theory framework. Lattice parameters, dopant atomic radii, bulk …

The release of radionuclides from spent fuel in a geological disposal facility is controlled by
the surface mediated dissolution of UO2 in groundwater. In this study we investigate the …

Actinide research at the nanoscale is gaining fundamental interest due to environmental and
industrial issues. The knowledge of the local structure and speciation of actinide …

Efficient and environmental-friendly recycling of rare earth polishing powder waste (REPPW)
is imperative not only to ecological well-being but also to sustainability of critical rare earth …

The quantitative understanding of the dissolution of nuclear fuel materials is essential for the
process design and development of an industrial-scale nuclear fuel reprocessing plant. The …

Monazite is a naturally occurring lanthanide (Ln) phosphate mineral [Ln x (PO4) y] and is the
main industrial source of the rare earth elements (REE), cerium and lanthanum. Endeavours …

The powder of phosphate Ca 1/4 Sr 1/4 Zr 2 (PO 4) 3 was synthesized by sol–gel processes
in the presence of citric acid and ethylene glycol. Ceramic samples were prepared from this …

The dissolution of Th1–x Ce x O2 solid solutions samples prepared by thermal conversion of
oxalate precursors was studied by varying independently several parameters (such as …

The microstructural evolution of several Ce1− xLnxO2− x/2 (Ln= Nd, Er, x= 0.28; 0.59 and
0.76) sintered pellets was studied during their dissolution in 4 M HNO3 at 90° C or 60° C …
