Synthesis and Characterization of π‐Extended Azulenes via Nucleophilic Substitution and Intramolecular Cyclization of 5‐Alkynyl‐6‐Fluoroazulenes

ChemistryEurope, EarlyView.
A modular synthetic approach enables the preparation of azulene‐fused heterocycles via nucleophilic aromatic substitution followed by intramolecular cyclization of alkynyl fluoroazulenes. The method allows the incorporation of various heteroatoms (N, O, S, Se, and Te), leading to structurally diverse heteroannulated azulenes.

Insight Into the Failure Mechanism of Conversion‐Alloy Anode Materials in Potassium‐Ion Batteries: A Case Study of Bi2Te3

Carbon Energy, EarlyView.
Through combining electrochemical profiles with multi‐scale microscopies, spectroscopy, and theoretical calculations, the failure processes and mechanisms of Bi2Te3 are identified into two stages: (1) the shuttle effect, dominating the first stage, results in the rapid capacity fading in the first several cycles and (2) the SEI accumulation, dominating

Modulating Redox Mechanism in Metal Chalcogenides by Precisely Controlling Phase Transition to Achieve Ultrafast and Ultra‐Stable Sodium‐Ion Batteries

Carbon Energy, EarlyView.
The typical conversion Na+ storage mechanism of ZnS/ZnSe was modulated toward surface redox pseudocapacitive reaction through precisely controlling the phase transition processes. The ZnS/ZnSe electrode presents ultra‐long cycling stability of 803 mAh g−1 after 1800 cycles and a capacity retention of 89% at ultrahigh current density of 20 A g−1 ...

Going from Pt to PGM‐free Catalysts: Effects of Ink Compositions on PEM Water Electrolysis

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Optimisation of cathode ink formulations regarding the ratio between catalyst, carbon and binder results in a boost in PEM water electrolysis performance. The optimisation can be transferred from pentlandites to platinum and selenide catalysts, wherein the metal chalcogenides show a stronger performance enhancement.
