pyFDRT: An open‐source Python tool for Fourier‐transform analysis of the distribution of relaxation times in electrochemical impedance spectra

open access: yesBulletin of the Korean Chemical Society, EarlyView.
pyFDRT is an open‐source tool that converts an impedance spectrum into a quantitative equivalent circuit. Its Fourier‐transform stage requires no discretization basis or regularization parameter, and the non‐negative refinement selects its own parameters, and an information criterion determines the relaxation process count.

Channel‐trap coupled charge modulation in sulfur‐vacancy‐rich nanotransducer for enhanced dual‐mode cancer catalytic therapy

open access: yesBMEMat, EarlyView.
Sulfur vacancy‐rich ZnS–NCx heterojunctions are engineered as dual‐function nanotransducers, in which channel‐trap‐coupled electronic pathways enable efficient capture and transport of ultrasound‐induced piezoelectrons. This vacancy‐mediated regulation simultaneously enhances sonodynamic activity and biomimetic POD/GSHOx catalysis, triggering a self ...

Recent Advances in Ionizing Radiation as a Nonequilibrium Chemical Field for Catalysis

open access: yesCarbon and Hydrogen, EarlyView.
Ionizing radiation acts as a nonequilibrium chemical field that generates reactive species and structural perturbations. These radiation‐induced effects bridge catalytic material construction, including metal loading, framework evolution, defect engineering, and carbon‐network reorganization, with selective transformations such as oxidation, reduction,

Boosting Sodium Storage Activity and Kinetics of Hard Carbon by Remodeling Oxygen Chemistry

open access: yesCarbon Energy, EarlyView.
A surface oxygen remodeling strategy is proposed to finely furnish the pseudographitic structure of hard carbon with rich closed pores and expanded interlayer spacings. Accordingly, the sodiation reactivity and kinetics are greatly reinforced to afford an elevated capacity of 360 mAh g−1 and outstanding rate capability of 225 mAh g−1 at 2 A g−1 ...

Synergistically Accelerating Zn2+ Transport and Desolvation Through Cation‐Deficient Ion Channels in High‐Performance Zn Metal Batteries

open access: yesCarbon Energy, EarlyView.
The novel ITO protective layer enables ultra‐stable Zn metal anodes. By synergistically accelerating Zn2+ desolvation and Zn2+ transport via its unique structure, the ITO layer suppresses dendrites and side reactions. This results in exceptional stability for over 6000 h at 2 mA cm–2 and stable operation in Zn ||MnO2 full‐cell configurations.
