Dynamics and Conformational Stability of Chiral Bay‐Phenolate‐Substituted Twisted Octaazaperopyrenedioxides (OAPPDOs)

open access: yesChemistry – A European Journal, EarlyView.
Chiral octaazaperopyrenedioxide (OAPPDO) fluorophores were obtained by functionalizing with BINOL and related fragments bridging the bay position. They possess conformational flexibility but remarkable thermal stability with respect to racemization of the central chromophore, which allowed the study of their chiroptical properties, including circular ...

Synthesizing polyethersulphone membranes with hybrid iron/nickel nanoparticles for dyes removal: An efficient biogenesis approach

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Industrial wastewater contamination by azo dyes poses a significant environmental challenge. This study reports the green synthesis of bimetallic iron/nickel (Fe/Ni) nanoparticles using moringa leaf extract, which acted as both a reducing and capping agent, and their incorporation into polyethersulphone (PES) membranes to produce eco‐friendly ...

Occurrence and Human Health Implications of Legacy Organochlorine Pesticides and Their Metabolites in Fruits and Vegetables of Bangladesh

open access: yesFood Safety and Health, EarlyView.
Multiple OCP isomers and/or metabolites along with their parent compounds were detected in commonly consumed fruits and vegetables of Bangladesh, possibly attributed to both recently and historically applied OCPs. However, all the detected values were below 0.01 mg/kg, indicating no potential human health risks through dietary intake. ABSTRACT Globally,
