Sustainable Materials Design With Multi‐Modal Artificial Intelligence

open access: yesAdvanced Science, EarlyView.
Critical mineral scarcity, high embodied carbon, and persistent pollution from materials processing intensify the need for sustainable materials design. This review frames the problem as multi‐objective optimization under heterogeneous, high‐dimensional evidence and highlights multi‐modal AI as an enabling pathway.

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

open access: yesAdvanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,

Synergizing Covalent‐Ionic Tri‐Site Coordination in P2‐type Na0.67Fe0.33Mn0.67O2 Induces Suppressed Layer‐Slipping and Stablized Lattice Oxygen for Sodium‐Ion Batteries at Wide Potential

open access: yesAdvanced Science, EarlyView.
Trans‐sublattice Cu/Mg/F three‐site coordination simultaneously stabilizes the oxygen framework and suppresses irreversible P2‐O2 phase transition and Jahn‐Teller distortion in Fe/Mn‐based layered cathodes. The optimized NFCMMOF enables highly reversible Fe3+/Fe4+ redox chemistry, accelerated Na+ transport, and robust interfacial kinetics, delivering ...
