| Abstract Scope |
The study aims to decipher the roles of Fe2O3 and Cr2O3 in the structural evolution of borosilicate-based model nuclear waste glasses using a combined experimental and computational materials science approach. Fe2O3- and Cr2O3-containing glasses have been synthesized using the melt-quench technique and characterized for their short-to-intermediate-range order and redox chemistry using 11B, 23Na, 27Al, and 29Si MAS NMR, Raman, UV-Visible, EPR, and Molecular dynamics (MD) simulations. The results obtained from these investigations shall be presented. |
