Hyperbranched Interpenetrating Hydrogen Bond Network (HIHBN) Proton Exchange Membrane for Fuel Cells Above 220 °C

Advanced Functional Materials, EarlyView.
A novel polymer electrolyte membrane with a hyperbranched interpenetrating hydrogen bond network structure is developed. The unique structure of the hyperbranched polymer contributes to a high glass transition temperature exceeding 400 °C, enabling its operation at elevated temperatures for fuel cell applications.

Solution‐Processable and Ambient‐Stable Highly Conductive p‐Type Polymers Derived from Dihydropyrazine and Ethylenedioxythiophene

Advanced Functional Materials, EarlyView.
This work presents π–conjugated polymers based on dihydropyrazine (DHP) and ethylenedioxythiophene (EDOT), developed to produce highly conductive, flexible films for printed electronics. By optimizing the DHP and EDOT ratio, strong and compact π–π stacking is achieved, resulting in polymer films with conductivities up to 1700 S cm−1 under ambient ...

Switching of Magnetic Order via Non‐Magnetic Al Addition in FeCoNiMnAlx Films

Advanced Functional Materials, EarlyView.
Non‐magnetic Al addition provides a sensitive handle to switch the magnetic order in high entropy FeCoNiMnAlx thin films via fcc to bcc phase transformation. Films with fcc structure exhibit a large exchange bias, while bcc films exhibit enhanced ferromagnetic properties, reflecting the magnetic ground state of Mn which switches from antiferromagnetic ...

Interfacial Interaction‐Mediated Regulation of Metal Oxidation States for Enhanced CO2 Reduction

Advanced Functional Materials, EarlyView.
A hybrid strategy is employed to optimize bismuth–oxygen interactions, precisely regulating interfacial bismuth–oxygen bonds during topochemical synthesis. This leads to vanadium oxynitride‐bismuth catalyst exhibiting high Faradaic efficiency and durability for formate production, attributed to enhanced reaction thermodynamics and kinetics.

f‐p‐d Gradient Orbital Coupling Induced Spin State Enhancement of Atomic Fe Sites for Efficient and Stable Oxygen Reduction Reaction

Advanced Functional Materials, EarlyView.
The f‐p‐d (Eu─O─Fe) gradient orbital coupling induces electron delocalization and the introduced f‐band of Eu shifts the spin state of the Fe center in FePc from low‐spin to intermediate‐spin. This strategy simultaneously enhances oxygen reduction reaction (ORR) activity, reaction kinetics, and stability, resulting in superior ORR performance and ...
