Atomically Dispersed Ni Site Catalysts Accelerating Sluggish Sulfur Redox Kinetics in Nonaqueous Zn‐S Batteries

Advanced Functional Materials, EarlyView.
An atomically dispersed Ni catalyst featuring Ni‐N4 coordination is developed as a sulfur host for nonaqueous Zn─S batteries. This configuration modulates the electronic structure to lower activation barriers during rate‐limiting steps and promotes a robust ZnF2‐rich cathode‐electrolyte interphase, thereby accelerating sulfur redox kinetics ...

Charge‐Tunable Coacervate Micelles for Separator Engineering in Lithium‐Sulfur Batteries

Advanced Functional Materials, EarlyView.
A separator engineering strategy based on charge‐tunable complex coacervate core micelles (C3Ms) is presented to form an ion‐selective layer regulating polysulfide transport in Li–S batteries. The micelles enable uniform adsorption onto commercial polypropylene separators and infiltration throughout the internal pore network, suppressing polysulfide ...

Polarization of ferroelectric PVDF film produced in Russia in glow discharge plasma

Учёные записки Казанского университета: Серия Физико-математические науки
Polarization of a polyvinylidene fluoride (PVDF) film containing 6 mol % tetrafluoroethylene in glow discharge plasma was examined. The polarization efficiency of the PVDF film produced in Russia was compared to that of a foreign counterpart.

Disentangling Bulk and Surface Contributions to Charge and Discharge Fading in High‐Voltage LiCoO2

Advanced Functional Materials, EarlyView.
High‐voltage operation of LiCoO2 accelerates capacity fading through bulk and surface degradation. By introducing a LiTaO3 coating to selectively suppress surface degradation, bulk and surface contributions to charge and discharge fading are decoupled.

Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

Advanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Engineering Local Polar Frustration in Lead‐Free Dielectric Ceramics for Ultrahigh Normalized Energy Storage Performance

Advanced Functional Materials, EarlyView.
Local polar frustration is engineered to stabilize an ergodic relaxer through nanoscale multiphase coexistence, suppressing long‐range ferroelectric order while preserving high polarization. This strategy delivers ultrahigh low‐field normalized energy density (Wa >0.020 mC cm−2), exceptional thermal stability, and a transferable design principle for ...
