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

Neural Assimilation and Accommodation in Trilinguals: An fMRI Study at 7 T
Human Brain Mapping, Volume 47, Issue 11, 01 August 2026.Using brain activation and representational similarity analysis at 7 T‐MRI, this study demonstrated that the trilingual brain flexibly modulated neural assimilation and accommodation. While Chinese and English shared highly similar neural representations, Japanese engaged distinct patterns, highlighting script‐driven effects on multilingual neural ...
