TL;DR: In this paper , an assessment of grain boundaries in chromia (Cr2O3) doped fuels has been carried out using high resolution transmission electron microscopy to assess the structure compared to undoped fuel produced via the same process.

TL;DR: In this paper , the configurational entropy associated with the structures observed at varying temperatures has been computed to assess its impact on stabilizing the amorphous structure of SiO2, which can be used in future work assessing the role of dopants, glass forming additions and radiation damage.

TL;DR: In this article , amorphous undoped and chromium oxide doped UO2 systems (containing 10−50 at.% Cr3+) were modelled using classical molecular dynamics methods incorporating Cr3+ into the well-used CRG potential library.
