TL;DR: Four metal-organic frameworks (MOF) with tetravalent uranium have been solvothermally synthesized by treating UCl4 with rigid dicarboxylate linkers in N,N-dimethylfomamide (DMF), showing that the structures are quite unstable upon removal of the encapsulated DMF solvent.

TL;DR: By controlling the water content, a new poly-oxo-metalate species containing 38 uranium centers has been solvothermally synthesized in the presence of benzoic acid in tetrahydrofuran (THF).

TL;DR: In this paper, a low temperature decomposition of Th(C2O4)2⋅2H2O and (N2H5)2U2(C 2O4 )5 ⋅nH 2O into nanograined ThO2 and UO2 powders, which will be used later as precursors for the generation of materials emulating the nuclear fuel high burn up structure (HBS) was investigated.

TL;DR: This compound was solvothermally synthesized from low-valent uranium in an N,N-dimethylformamide solvent under an inert atmosphere, favoring stabilization of the tetravalent oxidation state, which is confirmed by X-ray photoelectron spectroscopy analysis.

TL;DR: In this article, the authors describe the state of the art in European radioisotope thermoelectric generators and radiosotope heater units and outline the technical challenges and multidisciplinary skills required to develop what is a world leading, original, significant and transformative technology solution for planetary science and exploration missions from the mid 2020s onwards.
