Abstract In this work, zinc oxide (ZnO) was produced using extracts of Thymus (Z), Hibiscus rosa-sinensis (K), and Daucus carota (G). Furthermore, sodium carboxymethyl cellulose (CMC) polyvinyl alcohol (PVA) were combined with ZnO to form three novel nanocomposites. X-ray diffraction (XRD) used for the structural analysis, where semicrystalline nature (CMC/PVA)/ZnO nanocomposites confirmed. The characteristics functional groups that arose inside prepared samples identified by Fourier transform infrared spectroscopy (FTIR). Evidence successful preparation pure particles their carried out a transmission electron microscope (TEM). nanoparticles are mostly spherical, irregularly distributed, have radii ranging from 10 40 nm. Their anti-bacterial activity studied against B. subtilis , E. coli, Candida albicans . inhibition zones all coli 0, 19, 31, 23 mm PVA/CMC blend, PVA/CMC/ZnO (Z) (PCZ-Z), (K) (PCZ-K), (G) (PCZ-G), respectively, compared streptomycin control Gram-positive standard zone (34 mm). On other hand, equal 26, 33, 28 CMC/PVA, PCZ-Z, PCZ-K, PCZ-G, respectively. Based on these results, PCZ-K sample is most effective at resisting (91.17%) (94.28%). These do not harmful chemicals, making them strong candidates use in biological applications.

Herein bimetallic nanocomposites Ag with nickel and cobalt were synthesized by using the extract of W. coagulans. Nanocomposites synthesis confirmed UV-Visible at 430 nm for 504 Ag@Ni Ag@Co respectively. From XRD technique it was established that have crystalline nature face-centered cubic structure. A strong antibacterial behavior toward Gram-positive Bacteria Staphylococcus aureus 48.9% 32.1% inhibition Gram-negative bacteria E. coli 33.1% 25.7% zone observed Next composites exhibited electrifying 90.2% 82% degradation against methyl orange (MO) through photocatalysis. Furthermore, showed efficient adsorption capacity heavy metal (lead) pH 7 within 45 min 90% adsorptive removal lead ions from water significant antioxidant potential. The current finding suggested, silver-based as an appropriate promising candidate catalytic potentials toxic pollutants.

Abstract The aim of current study was to prepared zinc oxide nanofertilzers by ecofriendly friendly, economically feasible, free chemical contamination and safe for biological use. focused on crude extract Withania coagulans as reducing agent the green synthesis ZnO nano-particles. Biosynthesized NPs were characterized UV–Vis spectroscopy, XRD, FTIR GC–MS analysis. However, Nano fertilizer used analyze responses induced different doses [0, 25, 50,100, 200 mg/l Zn acetate (100 mg/l)] in Triticum aestivum (wheat). stimulatory inhibitory effects foliar application studied wheat ( ) with aspect biomass accumulation, morphological attributes, biochemical parameters anatomical modifications. Wheat plant showed significant p < 0.01) enhancement growth upon exposure at specific concentrations. In addition, increase chlorophyll content, carotenoids, carbohydrate protein contents. Antioxidant enzyme (POD, SOD, CAT) total flavonoid content also confirmed nurturing impact plant. Increased stem, leaf root parameters, all mitigating capacity when applied wheat. According research, might be growth, yield, biofortification plants.
