From Shear to Sound: Mechanics–Acoustics Mapping of TPMS Lattices

Advanced Engineering Materials, EarlyView.
Triply periodic minimal surface (TPMS) lattices are mapped across mechanical and acoustic performance, revealing that descriptors validated in compression fail under shear. First‐time comparison with trusses included. A transition from porous to resonance‐driven absorption emerges at 25% density.

Role of Intrinsic Electron Trapping in Negative Charging of Amorphous Alumina

Advanced Functional Materials, EarlyView.
Intrinsic electron trapping in amorphous Al2O3 is examined using hybrid‐DFT models spanning a wide density range. Both spontaneous and thermally activated trapping are identified, with pronounced spontaneous localization in dense, partly crystallized structures.

Graded‐Interface Dual‐Environment Hydrogel‐Polymer Electrolyte for Stabilized Anode and Sustained Cathode Kinetics in Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A graded‐interface hydrogel‐polymer electrolyte decouples water activity to simultaneously stabilize the Zn anode and sustain cathode kinetics. The flexible design supports dendrite‐free cycling over 1600 h, high capacity in both MnO2 and V2O5 full cells, and stable pouch‐cell performance under bending, resolving the fundamental water conflict in ...
