Convergent Valorization via Scalable C═N Bond Electrosynthesis Through Metal‐Dopant Interfacial Engineering in a Flow Electrolyzer

open access: yesAngewandte Chemie, EarlyView.
This study establishes an innovative approach to synthesize organonitrogens featuring C═N bonds efficiently using non‐precious metal‐doped MoS2 in a flow electrolyzer. Fe dopant significantly enhances Faradaic efficiency and yield rate, achieving over 81% and 2630 mmol h−1 g−1 for formaldoxime production. This platform upcycles pollutants into valuable

Supramolecularly Directed Confined Crystallization of Lamellar Carbon Nitride for Efficient Photocatalytic Hydrogen Generation

open access: yesAdvanced Energy Materials, EarlyView.
ABSTRACT Sustainable hydrogen generation through water splitting is key to realizing a future hydrogen economy. In this study, we achieved molecular‐level control over self‐assembled supramolecular complexes of cyanuric acid and 3‐amino 1,2,4 triazole (AT) monomers. This was coupled with molten‐salt‐assisted thermal polymerization in a eutectic mixture

Uncovering Cystic Fibrosis Carrier: Insights From a Heterozygous CFTR‐F508del Rabbit Model

open access: yesInternational Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Chronic rhinosinusitis (CRS) is a heterogeneous inflammatory disorder frequently associated with impaired mucociliary clearance and bacterial infection. Individuals carrying a single cystic fibrosis transmembrane conductance regulator (CFTR) mutation exhibit partial CFTR dysfunction and are increasingly recognized as being at risk ...
