Hydrodynamic Selection of Polymorphic Assembly Pathways in Plant Protein Amyloid Fibrils

Advanced Science, EarlyView.
Hydrodynamic conditions are revealed to govern polymorphic assembly of soy protein amyloid fibrils. Distinct flow‐induced drafting, kissing, and docking dynamics direct fibril growth into multiple morphologies, linking fluid mechanics with nanoscale assembly and enabling rational design of functional amyloid materials.

Field‐Driven Proton Transport in Water Revealed by Machine Learning Molecular Dynamics

Advanced Science, EarlyView.
Using a reactive and polarizable machine‐learning molecular dynamics (MLMD) framework, the authors show that excess‐proton drift remains nearly linear with applied electric field up to 0.15 V/Å. It is also found that the protonic defect mitigates the field‐induced structural changes observed in neat water, revealing a distinct high‐field response of ...

Surface‐Selective Pt Enrichment for Stabilizing Ultrathin 2D PtCu Nanosheets Toward Durable Oxygen Reduction

Advanced Science, EarlyView.
Ultrathin 2D alloy nanosheet catalysts could offer exceptional catalytic activity but suffer from severe structural instability. Here, a surface‐selective Pt enrichment strategy via galvanic replacement effectively stabilizes PtCu Nanosheets while preserving their ∼ 1 nm thickness and (111) facets.

Intelligent Polymer Electrolytes for Next‐Generation Zinc‐Based Energy Storage Devices

Advanced Science, EarlyView.
Intelligent polymer electrolytes are organized into a three‐level hierarchy that advances zinc‐based energy storage from passive ion conduction toward active, adaptive, and intelligent operation. Molecular regulation of Zn+ coordination, water activity, desolvation, ion flux, and interfaces underpins adaptive self‐healing, anti‐freezing, adhesion, and ...

Overcoming the *H‐NOx Coupling Bottleneck via Palladium‐Enabled Relay Catalysis on CuCo2O4 Toward Ampere‐Level Nitrate‐to‐Ammonia

Advanced Science, EarlyView.
Pd‐doped hollow spiny CuCo2O4 microspheres deliver ampere‐level electrocatalytic nitrate to ammonia. Cu and Co sites undergo relay catalysis for sequential nitrate reduction, while Pd accelerates water dissociation to supply abundant active hydrogen (*H).
