Domain‐Knowledge‑Guided Rule Extraction for Governing Nepheline Amount in High‑Level Waste Glasses

open access: yesInternational Journal of Applied Glass Science, Volume 17, Issue 4, October 2026.
ABSTRACT Nepheline crystallization during canister centerline cooling is one of the most constraining factors limiting waste loading in high‐level waste (HLW) borosilicate glasses. Existing predictive models treat nepheline formation as a binary outcome, yet durability degradation depends continuously on nepheline fraction.

Speciation‐Controlled C–F Bond Functionalization Enabled by Zwitterionic Pnictinidenes

open access: yesAngewandte Chemie, Volume 138, Issue 39, 21 September 2026.
Zwitterionic pnictinidenes turn C–F activation into C–X bond construction, enabling broad defluorinative functionalization of polyfluoro(hetero)arenes under mild conditions. Rather than following a metallomimetic Sb(I)/Sb(III) redox turnover, catalysis is redirected by ligand scrambling into a redox‐neutral manifold, revealing catalyst speciation as a ...

Optical Basicity of Glasses: Review and Application in Nuclear Glass Formulation

open access: yesInternational Journal of Applied Glass Science, Volume 17, Issue 4, October 2026.
A self‐consistent set of optical basicity (OB) values was compiled and evaluated for 95 binary oxides using electronegativity, ionic–covalent, and optical‐property approaches, providing a robust basis for estimating the basicity of complex compounds and glasses.

Volatilization of Na2O and Its Impact on the Processing of Solid Electrolytes

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 10, October 2026.
The volatilization of oxides from ceramics during sintering can have a detrimental impact on their physical properties. As shown in the figure, the release of Na2O from Na3.4Zr2Si2.4P0.6O12 leads to the formation of a ZrO2 surface layer that blocks ionic conductivity.
