Silver@graphene oxide nanocomposite was synthesized through an efficient approach, characterized by FTIR, EDX, and TEM instruments and then was used as adsorbent for imidacloprid removal from water in batch procedure. Effective variants such as contact time, pH, adsorbent dosage, and initial concentration of imidacloprid on procedure by two methods, one at a time and experimental design methods, were studied. Results in optimum conditions based on one at a time experiments is removal of 63% of the pesticide from 50 mL water containing 10 mg/L of imidacloprid by 0.03 g of the adsorbent at pH = 6.6 after 60 min while, experimental design method predict similarity results, 66% uptake of the poison by 0.06 g of the adsorbent in pH = 8. Kinetics and isotherm for adsorption processes follows Freundlich and pseudo-second-order models. Results confirm that Ag@graphene oxide nanocomposite can be applicable for removal of imidacloprid from real polluted water.

Today, active packaging has become essential to increase food safety and decrease food spoilage. In this study, the aim was to delay spoilage and increase the shelf life of rainbow fish fillets with a new hybrid nanocomposite active packaging. Packaging was fabricated with Ethylene vinyl acetate and active compounds such as rosemary extract, zinc oxide nanoparticles, and modified iron (Fe-MMT).

This study aimed to synthesize a nanocomposite based on tertiary metal oxide FeO@CuO@ZnONPs, starch, ethylcellulose, and collagen, as well as evaluate its biological activities. The prepared nanocomposites were characterized using physicochemical analysis, which included FTIR, XRD, and DLS. Additionally, topographical analysis using FI-SEM, EDX, mapping, HR-TEM, and SAED affirmed the molecular structure and nanosized of formulated nanocomposites.

The increasing prevalence of micropollutants like cationic and anionic dyes in wastewater creates an influential environmental challenge, mainly due to their toxic effects and persistence. Current methods often lack the efficiency and versatility to cope with a wide variety of contaminants. This study explores the modification of TEMPO-oxidized cellulose nanofibers (TOCNF) using (3-chloro-2-hydroxypropyl) trimethylammonium chloride (CHPTAC) to enhance their cationic properties.

The broader use of botanical pesticides has been limited by shorter residual activity on plants, slower onset of action, and higher costs compared with conventional pesticides. These challenges could be overcome by the development of simple, cost-effective, and long-lasting preventive nanocomposites for botanical pesticides. In this study, we successfully developed a low-cost ethyl cellulose (EC)-based delivery system for the botanical pesticide osthole (OST), designed to provide extended preventive protection against infestations.
