NH3‐Guided Low‐Temperature Nanostructural Refinement Boosts Visible‐Light‐Driven H2O2 Synthesis in Ionic Carbon Nitrides

Advanced Materials, EarlyView.
A nanostructural refinement strategy is reported for KPHI photocatalysts using NH4Cl in a molten salt environment to induce coherent domain fragmentation and controlled cyano defect formation. This dual modification promotes n→π* transitions, enhances charge separation, and accelerates ORR kinetics, yielding exceptional AQY values of 49% (410 nm) and 5%

Proton Selective Nanoporous Atomically Thin Graphene Membranes for Vanadium Redox Flow Batteries

Advanced Materials, EarlyView.
A scalable high‐performance proton‐exchange‐membrane architecture is demonstrated that integrates monolayer CVD graphene with Ar plasma‐engineered Angstrom‐scale proton‐selective pores, stacked to mitigate non‐selective defects, and interfaced with an ultrathin (≈300 nm) polybenzimidazole layer sandwiched between two Nafion 211 sheets.

Spatiotemporal Reservoir Computing with a Reconfigurable Multifunctional Memristor Array

Advanced Materials, EarlyView.
This study presents a hardware physical reservoir computing system using a tri‐modal memristive crossbar array. Stochastic masking, bistable nonlinear activation, and analog readout enable fully in‐memory spatiotemporal processing. Demonstrations on cellular automata, Lorenz prediction, ADHD EEG classification, and chaotic KS modeling highlight its ...

Resolving the Structural Duality of Graphene Grain Boundaries

Advanced Materials, EarlyView.
Cantilever ncAFM resolves the atomic structure of grain boundaries in graphene, revealing coexisting stable and metastable types. Both contain pentagon/heptagon defects, but metastable GBs show irregular geometries. Modeling shows metastable GBs form under compression, exhibiting vertical corrugation, while stable GBs are flat.

Thermally Drawn Multifunctional All‐Hydrogel Fibers for Anti‐Fibrotic and Multimodal Neural Interfaces

Advanced Materials, EarlyView.
Hydrogels demonstrate material properties that mimic the mechanical and chemical environments of biological tissues. Yet, they face challenges during their integration into 3D interfaces. By identifying a class of thermoplastic hydrogels, a strategy is developed to pattern hydrogels in thermally drawn fibers.
