Balancing Hydrophobicity and Hydrophilicity: Dual Filler‐Engineered Proton Exchange Membranes for Durable, High‐Power Fuel Cells

open access: yesAdvanced Functional Materials, EarlyView.
Polarity‐matched Zr–MOFs program Nafion's nanoscale morphology during solution casting. Hydrophilic UiO‐66 preserves hydrated pathways, while hydrophobic UiO‐67 increases the proton hopping sites by densifying ionic clusters. Combining both fillers yields a membrane that delivers 176 mS cm−1 conductivity, reaches 1.46 W cm−2 under 200 kPa, and triples ...

Confinement‐Engineered Thermally Programmed Ion‐Gating Separator for Decoupling Thermal–Electrochemical Feedback in High‐Energy Lithium‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A new phase‐change material encapsulated membrane offers more thermal resilience stability and safety than the conventional separators for batteries. ABSTRACT Thermal runaway in lithium‐ion batteries arises from the intrinsic coupling between heat generation and ion transport, yet conventional shutdown separators primarily rely on passive pore collapse

Domain Engineering and Anisotropic Domain‐Wall Photovoltaic Effects in Ferroelectric SnS

open access: yesAdvanced Functional Materials, EarlyView.
The bulk photovoltaic effect at domain walls in the in‐plane ferroelectric 2D semiconductor SnS is investigated using periodic domain structures. Unlike conventional oxide ferroelectrics, domain walls of SnS do not contribute to photocurrent generation perpendicular to the domain walls.

Direct Integration of Conductive, Emissive Perovskite Nanocrystals Into Efficient Light‐Emitting Diodes Without Post‐Synthetic Ligand Exchange

open access: yesAdvanced Functional Materials, EarlyView.
We demonstrate the direct integration of CsPbBr3 perovskite nanocrystals (PNCs) into optoelectronic devices without post‐synthetic ligand exchange. This is achieved by synthesizing PNCs stabilized by strong‐binding‐energy oleylammonium–bromide pairs instead of oleate ligands. The resultant low ligand density and minimized surface defects enhance charge
