Biomacromolecular engineering of redox-active chitosan-polypyrrole-clay hybrid materials for machine learning-assisted desulfurization and supercapacitor application.

The bentonite chitosan polypyrrole (Bent-CS-PPy) composite was engineered as a multifunctional material with dual capabilities: the efficient adsorption of dibenzothiophene (DBT) from model fuel and application as an electrode in electrochemical energy storage systems. This hybrid composite leverages the layered morphology and cation-exchange capacity of bentonite, the hydrophilic and functional -OH and -NH groups of chitosan, and the redox-active, π-conjugated polymeric framework of polypyrrole, resulting in a porous, conductive, and chemically interactive matrix. In adsorptive desulfurization studies, the Bent-CS-PPy composite exhibited a DBT removal efficiency of 81.

Enhanced Insecticidal Activity of Thiamethoxam by Zinc Oxide Nanoparticles: A Novel Nanotechnology Approach for Pest Control.

Indiscriminate and unregulated application of pesticides produces deleterious effect in various groups of organisms including humans and the environment. To solve these issues, it has been reported that the residue-free green nanocomposite synergistically enhances the pesticide efficacy. In this study, ZnO nanoparticles (NPs) with a thiamethoxam nanocomposite were synthesized and we investigated their synergistic effect on 4th instar larvae of (Lepidoptera: Noctuidae).
