TL;DR: This work explores the size dependence of both crystal and electronic properties of CeO2 nanoparticles (NPs) with different sizes by state-of-the art spectroscopic techniques and demonstrates that the as-synthesized NPs crystallize in the fluorite structure and they are predominantly composed of CeIV ions.

TL;DR: In this article, the sorption of actinides (Th, U, Am) was studied in dependence of the solid-to-liquid (S/L) ratio (0.5 −20.0 ) and the calcium-tosilicon (C:S) ratio.

TL;DR: The first synthesis of mixed oxide nanoparticles was reported in this article, where the obtained nanopowders were characterized by X-ray diffraction, thermal ionization mass spectrometry, transmission electron microscopy, Raman spectroscopy, and U M$(4)$ edge high-energy-resolution Xray absorption near edge structure (HR-XANES).

TL;DR: The first batch of pure U-oxide microparticles produced in Juelich was successfully certified regarding the isotopic composition and the U amount per particle and applied in an international laboratory exercise NUSIMEP-9.

TL;DR: In this article , the authors present a coprecipitation study, in which hexavalent U (U(VI)) was reduced during the synthesis of magnetite and pentavalent u (V)) was the dominant species.
