Green initiative: use of cow dung slurry for treatment of industrial effluent.

This research dives into highlighting potential usage of cow dung as a co-substrate to reduce the organic carbon load of toxic industrial effluents through batch and semi continuous anaerobic process. One such effluent stream is released during caprolactam manufacturing having pH of about 2, 0.4% ammonical nitrogen, and COD up to 55,000 mg/L which varies often.

Green and Chemical Synthesis of Copper Oxide Nanoparticles for Antifungal Protection and Plant Growth Enhancement of Chickpea via Nanopriming.

This study reports the synthesis of copper oxide nanoparticles (CuO NPs) using chemical and green methods utilizing pineapple waste, including fresh peels, dried peels, and pineapple pomace from two different copper precursors, targeting antifungal activity and plant growth enhancement. Phytochemical analysis confirmed the presence of bioactive compounds with dry peel extract proving to be most effective for green synthesis. CuO NP formation was evidenced by color change and confirmed by UV-vis, Fourier transform infrared (FTIR), X-ray diffraction (XRD), and transmission electron microscopy (TEM) analysis, revealing particle sizes under 50 nm.

Nanofomulation of zinc oxide and chitosan zinc sustain oxidative stress and alter secondary metabolite profile in tobacco.

Advancement in nanotechnology has improved ways for large-scale production and characterization of nanoparticles of physiologically important metals. The current study explores the impact of Zinc Oxide Nanoparticles (ZnO-NP) and Chitosan-Zinc oxide nano-bioformulation (CH-ZnO) in tissue culture raised callus of . Results indicated augmented biomass in CH-ZnO treated callus, while a reduced biomass was observed in ZnO-NP treated callus, at all the concentrations tested.
