Electroactive Foldamers Endowed with Tetrathiafulvalene Units: From Highly Stable Single Helical Structures to Redox‐Triggered Duplex Formation

open access: yesChemistry – An Asian Journal, EarlyView.
Certain foldamers can form multiple helices, which is of interest in materials science, among other fields. By grafting tetrathiafulvalene units onto the ends of a helical oligomer, we report the synthesis and study of a foldamer that shows remarkably high stability in the single‐helical state.

Scaling of Planar Sodium‐Nickel Chloride Battery Cells to 90 cm2 Active Area

open access: yesBatteries &Supercaps, Volume 8, Issue 3, March 2025.
Large planar Na β′′ alumina electrolytes are prepared by tape‐casting and die‐pressing. These ceramic electrolytes are used to prepare planar sodium‐nickel chloride cells with 90 cm2 active area, providing a high capacity of 7 Ah. Successful cell cycling is demonstrated at 300 °C at rates up to C/4 (20 mA cm−2) for a cumulative capacity of 3.6 Ah cm−2.

Oxidant-free annulation of α-hydroxy ketones with diamines using aluminum(III) chloride: A supramolecular approach for practical quinoxaline synthesis

open access: yesResults in Chemistry
The conventional reaction of α-hydroxy ketones (acyloins) with arene-1,2-diamines typically requires an oxidant to facilitate a tandem oxidative condensation, resulting in quinoxaline derivatives. In this study, an innovative approach has been introduced
