Covalent Organic Nanosheets with a Tunable Electronic Structure to Achieve Unprecedented Stability and High‐Performance in Sodium‐Ion Batteries

Small, EarlyView.
The new type of covalent organic nanosheets as an anode material for sodium‐ion batteries is developed by the introduction of both the benzothiadiazole motif and fluorine atoms to form the D/A‐CON‐10‐F electrode which finally demonstrates high electrical conductivities and discharge capacity of ≈637 mA h g−1 during 500 cycles at the current density of ...

Recent developments in the chemistry and enzyme inhibitory activity of fused thiazoles and thiadiazoles

Vietnam Journal of Chemistry, EarlyView.
Abstract The combination of cyclization reactions of thiadiazoles and benzothiazoles with Pd‐catalyzed cross‐coupling reactions provided a convenient synthesis of annulated, fluorinated and non‐fluorinated heterocycles, such as 1,3,4‐thiadiazolo[3,2‐a]pyrimidin‐5‐ones, benzothiazolo[3,2‐a]pyridimidin‐4‐ones, benzothiazolo[2,3‐b]quinazolin‐12‐ones and ...

Salicylate plant defences reduce aphid nutritional quality and increase predator consumption

Ecological Entomology, EarlyView.
Salicylic acid‐induced defences diminish Macrosiphum euphorbiae performance and nutritional quality by reducing body protein and lipid content. Ladybird beetle predators (Hippodamia convergens) consumed more low‐quality aphids compared to high‐quality aphids, exhibiting compensatory feeding response to nutrient‐deficient p prey.

Organic Interlayer for Enhanced Buried Interfaces in Wide‐Bandgap Perovskite Solar Cells

ChemSusChem, Volume 18, Issue 16, August 6, 2025.
High‐performance, stable wide‐bandgap perovskite solar cells (PSCs) are vital for tandem cell development, yet nonradiative interfacial recombination limits efficiency. Herein, a donor–acceptor quinoxaline‐based interlayer is introduced (QxNN) at the NiOx/perovskite interface in p‐i‐n PSCs. This interlayer passivates defects, enhances charge extraction
