Proton Conductive Supramolecular Architectures Based on a Cobalt Terpyridine–Biimidazole Complex: Hydrogen‐Bonded Hexamer and Mixed‐Valence 1D Chain

open access: yesChemistry – A European Journal, EarlyView.
Hydrogen‐bonded cobalt(II/III) coordination complexes incorporating 2,2′‐biimidazole and COOH‐terpyridine ligands were synthesized, forming a hexameric cluster [1]6 and a rare mixed‐valence 1D chain [2]n. Single‐crystal X‐ray diffraction revealed hydrogen‐bonding networks and 1D channels.

Aqueous Supercapacitor with Wide‐Temperature Operability and over 100,000 Cycles Enabled by Water‐in‐Salt Electrolyte

open access: yesChemSusChem, Volume 18, Issue 6, March 15, 2025.
This study presents a symmetric supercapacitor with activated carbon electrodes and a “water‐in‐salt” electrolyte (WiSE) based on lithium perchlorate, offering over 100,000 cycles with over 90 % capacity retention. The supercapacitor operates efficiently from −20 to 80 °C, enhancing performance, stability, and all‐season operability.

The Electrochemical Oxidation of Organic Selenides and Selenoxides [PDF]

open access: yes, 1997
The electrochemical oxidation of alkyl and aryl selenides was investigated in acetonitrile. The oxidation of diphenyl selenide and di(4‐methylphenyl) selenide led primarily to the formation of their respective selenoxides, which were identified by ...

A New Low‐Rate Stable Hydrogel Cathode for Aqueous Zn‐ion Batteries

open access: yesChemSusChem, EarlyView.
A mixed ion‐ and electron‐conducting hydrogel enables low‐rate stability of aqueous Zn‐ion batteries. Aqueous Zn‐ion batteries (ZIBs) are attractive candidates for large‐scale energy storage owing to the abundance, low cost, and intrinsic safety of Zn metal.

Gallium Vanadium Oxide‐Based Free‐Standing Versatile Electrode for Next‐Generation Lithium and Sodium Energy Storage: Combined Experimental and First‐Principles Insights into Electrochemical Performance

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A gallium vanadium oxide (GVO)‐based free‐standing electrode is fabricated via a two‐step process involving a wet ball mill followed by thermal treatment and the surface‐engineered tape casting technique. The resulting GVO‐based free‐standing composite electrode has been successfully utilized for four distinct energy storage applications without any ...

Bio‐Inspired Ordered WO3 Nano‐Helixes Enable Multi‐Band Electrochromic Smart Windows with Ultrafast Switching and Robust Cyclability

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Biomimetic ordered nano‐helix WO3 films enable multi‐band electrochromic photothermal management across the visible, near‐infrared, mid‐ and long‐wave infrared spectra, with ultrafast switching (<3 s) and robust durability (>10 000 cycles). These findings establish new paradigms for next‐generation photothermal management systems and energy‐efficient ...
