Abstract
Oh, now I see! The precipitates formed during ThIV hydrolysis are ThO2 nanoparticles, which in their initial stages of formation are a mixture of ultra-small nanoparticles and Th hexamer clusters. This new structural insight is made possible by the combined use of two synchrotron techniques: HEXS and XANES in HERFD mode, which probe short- and medium-range order in the sample under study. More information can be found in the Full Paper by L. Amidani et al. on page 252.
