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.

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

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 ...

A strongly correlated electron system (SCES) exhibits pronounced insulating behavior due to Coulombic repulsion between cations, which generates a charge gap. This study investigates the tuning of the band structure in NiWO4‐based SCES via Cu doping at substitutional sites and Li doping at interstitial sites.

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions
A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...

High‐Entropy Magnetism of Murunskite
The study of murunskite (K2FeCu3S4) reveals that its magnetic and orbital order emerges in a simple I4/mmm crystal structure with complete disorder in the transition metal positions. Mixed‐valence Fe ions randomly occupy 1/4 of the tetrahedral sites, with the remaining 3/4 being filled by non‐magnetic Cu+ ions.

The PDEM‐based SIGPE provides a dynamic nanophase from Li+‐bridged molecular self‐association, enhancing electrochemical stability and facilitating uniform Li+ ion flux at the interface. This unique solvation structure results in a hetero species‐driven inorganic‐rich SEI and long‐term cycle stability, suggesting that a PFAS‐free Li+‐containing monomer

This study introduces a rapid, microwave‐assisted synthetic method for halide argyrodite solid‐state electrolytes Li6PS5X${\rm Li}_6 {\rm PS}_5X$ (X=$X =$ Cl−${\rm Cl}^-$, Br−${\rm Br}^-$, I−${\rm I}^-$). Microwave synthesis increases S2−${\rm S}^{2-}$/X−$X^-$ site disorder and rotational disorder of the isolated PS43−${{\mathrm{PS}}_{4}}^{3 ...
