Engineering Intelligent Graphene Oxide‐Cellulose Membranes: Suppressing Thermal Runaway for a Safer Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A novel thermos‐responsive hydroxypropyl cellulose/graphene oxide (HPC/GO) composite membrane is fabricated for reversible temperature‐gated ion transport in aqueous zinc‐ion batteries. Enabled by LCST‐driven structural transition, unimpeded ion diffusion at room temperature delivers high capacity, while elevated temperature suppresses transport; full ...

Carbon Shell‐Encapsulated PtFe Catalysts in High Temperature Polymer Electrolyte Membrane Fuel Cells: Balancing Molecular Sieving and Diffusion for Enhanced Reactant Access

Advanced Functional Materials, EarlyView.
Scanning electrochemical microscopy reveals reactant diffusion through porous carbon shells to PtFe cores, while the carbon‐encapsulated PtFe enables high‐performance HT‐PEMFC operation by sieving phosphate ions that induce catalyst poisoning. ABSTRACT High‐temperature polymer electrolyte membrane fuel cells (HT‐PEMFCs) operating at 160°C on phosphoric

Residual‐Lithium‐to‐LiF Conversion Enables a LiF–Fluorinated Carbon Interphase for Reconstruction‐Resistant Ni‐Rich Cathodes

Advanced Functional Materials, EarlyView.
A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...

Coating Artificial Spider Silk Fiber with Magnetic FeCo: An Effective Strategy for Creating a Flexible Magneto‐Responsive Material

Advanced Functional Materials, EarlyView.
An original method is presented for producing artificial spider silk fibers with magnetic and magnetomechanical responsiveness, which consists in coating them with a nanometer‐thick layer of FeCo alloy by sputtering deposition. The challenge of combining organic materials and inorganic magnetic nanostructures is addressed, thus taking a step forward ...

Ultrasensitive Anti‐Stokes Luminescence Thermometry in Transition Metal Dichalcogenide Monolayers

Advanced Functional Materials, EarlyView.
We demonstrate a highly sensitive nanothermometer using anti‐Stokes photoluminescence, also known as photoluminescence upconversion (UPL), in monolayer tungsten disulfide. A strong resonantly enhanced UPL is observed, confirming the central role of optical phonons in the PL upconversion mechanism.

Interplay Between Phase Evolution, Fe Migration, and Oxygen Redox in O3‐Type NaxFeyMn1−yO2 Cathodes

Advanced Functional Materials, EarlyView.
Why do Na‐ion battery cathodes, that are compositionally closely related, follow different structural paths during battery operation? This work shows how Fe content controls when iron atoms migrate from their original sites. Early migration locks the layers and blocks key phase transitions, whereas delayed migration permits fuller structural ...
