Sheet‐Size‐Dependent Mosaicity of 2D Phyllosilicate Membranes
Advanced Science, EarlyView.This study explores how the size of 2D vermiculite sheets affects the structure of laminar membranes. High‐resolution x‐ray diffraction reveals how sheet size governs structural disorder and crystallinity. These changes directly impact ion permeability.

Advanced Science, EarlyView.Defect‐engineered LiYO2 interlayers are designed through aliovalent Zn2+ and Zr4+ substitution to regulate Li+ point‐defect chemistry in Ni‐rich cathodes. Compared with Li‐excess‐type LYZnO, Li‐vacancy‐type LYZrO enables faster Li+ transport, suppresses Li6PS5Cl decomposition, lowers interfacial resistance, and mitigates polarization growth, thereby ...
