Synergistic Molecular Modulation of ππ Stacking for High‐Performance Pitch‐Derived Hard Carbon Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A synergistic molecular strategy is demonstrated to disrupt intrinsic ππ stacking in pitch, boosting 6‐fold sulfonation, yielding a hard carbon with 0.371 nm interlayer spacing and maximized closed pores, and achieving a high reversible capacity, remarkable rate capability (205.6 mAh g−1 at 2 A g−1) and cyclic stability.

Self‐Supported SiC@Graphene Porous Array Electrodes for Ultrastable Supercapacitors

open access: yesElectron, EarlyView.
Self‐supported SiC–graphene porous array electrodes are fabricated through a novel steam‐assisted etching and in situ pyrolysis strategy. They deliver a high energy density of 4.9 μWh cm−2 at 150°C with 89.55% capacitance retention over 10,000 cycles, presenting a new approach for high‐temperature supercapacitors.

Recent Progress on Graphitic Carbon Nitride–Based Photocatalysts for Hydrogen Peroxide Synthesis

open access: yesExploration, EarlyView.
This review summarizes recent progress in using graphitic carbon nitride (g‐C3N4) photocatalysts to produce hydrogen peroxide (H2O2). It highlights how solar energy can cleanly convert water and oxygen into this valuable chemical. We discuss key modification strategies, such as defect engineering, doping, and junction construction, to enhance ...

Ordered assembly of Cas12a for better performance of CRISPR/Cas system with application to the diagnosis of dental caries

open access: yesInterdisciplinary Medicine, EarlyView.
Here, we present a tetrahedral DNA framework (TDF)‐mediated Cas12a ordered assembly strategy. TDFs arrange CRISPR/Cas12a into ordered structures controllably, enhancing catalytic efficiency through localized Cas12a hotspots while maintaining spatial intervals to facilitate substrate diffusion.

Reprocessable Disulfide‐Based Vitrimers with Adhesive Properties

open access: yesMacromolecular Rapid Communications, EarlyView.
A dual‐curing strategy combining UV‐induced thiol–ene polymerization and thermal thiol–epoxy curing was used to prepare disulfide‐based vitrimer networks with reprocessable, recyclable, and adhesive properties enabled by dynamic disulfide exchange. ABSTRACT A family of disulfide (S–S) containing thiol–vinyl–epoxy dynamic networks are presented.

Crystallization in Poly(Ethylene Oxide) Thin Films: Roles of Shear, Confinement, and Homoepitaxy

open access: yesMacromolecular Rapid Communications, EarlyView.
A comprehensive three‐mechanism framework governing PEO crystallization orientation in thin films was established using GIWAXS and molecular‐level PM‐IRRAS analysis. We demonstrate systematic switching between shear‐induced edge‐on and confinement‐ or homoepitaxy‐induced flat‐on alignment.
