Molecularly Engineered Dual‐Crosslinked Polymer Dielectrics for 200 °C Capacitive Energy Storage

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work establishes a molecular engineering strategy that constructs a robust dual‐crosslinked network in polymer nanocomposites, achieving a record‐high energy density of 5.17 J cm−3 with >90% efficiency at 200 °C. The multiscale‐validated design simultaneously enhances dielectric polarization and introduces deep electron traps, resulting in ...

Lattice‐Strained Cu2O‐Ni/NiO Heterostructure Enables Selective Electrocatalytic C–C Coupling of Alcohols to Cinnamaldehyde in Aqueous Medium

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study achieved the selective oxidation C–C coupling of PhCH2OH with EtOH to form cinnamaldehyde (CAL) on a designed Cu2O‐Ni/NiO heterojunction catalyst. By employing a salt precipitation strategy to balance the pH and cation concentration, an 86% conversion rate of PhCH2OH and a 67% high selectivity for CAL were realized.

A Robust Densification Strategy Toward Ultrahigh Energy Density in All‐Organic Dielectric Polymer Films

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A scalable densification strategy is proposed by incorporating sucrose into a fluoropolymer matrix to build a robust hydrogen‐bond crosslinking network. The intermolecular interactions effectively facilitate polar phase transformation and reduce free volume fraction.

Helical Fiber‐Shaped Aqueous Zn‐Ion Batteries with Modified Zn Anode and Self‐Healing Gel Electrolyte for Flexible Electronics

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A triple synergistic strategy (bismuth‐modified Zn@CNTF anode, helical electrode architecture, and self‐healing gel electrolyte) endows fiber‐shaped aqueous Zn‐ion batteries with outstanding stability. The device delivers a high energy density of 130.54 Wh·kg−1 and retains ≈90.2% of its initial capacity after 1000 dynamic bending cycles, representing a
