Degradation of 2, 4, 6-trinitrotoluene (TNT) from aqueous solution by coupled electrocoagulation process with persulfate salt.

Purpose: The 2, 4, 6-trinitrotoluene (TNT) is the major explosive extensively applied in demolition of structure, military activity, and mining industry. This research was investigating the degradation rate of TNT in aqueous solution using electrochemical combined with persulfate anions.

Methods: In this study, the effect of seven independent variables including pH, reaction time, current density, type (NaCl, NaSO, NaNO) and concentration of salts, initial concentration of TNT, scavenger type, and persulfate concentration were studied on TNT removal.

24-Epibrasinolide Modulates the Vase Life of Lisianthus Cut Flowers by Modulating ACC Oxidase Enzyme Activity and Physiological Responses.

Ethylene is the most important factor playing roles in senescence and deterioration of harvested crops including cut flowers. Brassinosteroids (BRs), as natural phytohormones, have been reported to differently modulate ethylene production and related senescence processes in different crops. This study was carried out to determine the effects of different levels of 24-epibrassinolide (EBL) on ACC oxidase enzyme activity, the final enzyme in ethylene biosynthesis pathway, vase life, and senescence rate in lisianthus cut flowers.

Phytosynthesis of silver nanoparticles using Artemisia marschalliana Sprengel aerial part extract and assessment of their antioxidant, anticancer, and antibacterial properties.

A rapid phytosynthesis of silver nanoparticles (AgNPs) using an extract from the aerial parts of Artemisia marschalliana Sprengel was investigated in this study. The synthesized AgNPs using A. marschalliana extract was analyzed by UV-visible spectroscopy, X-ray diffraction, and Fourier transform infrared spectroscopy and further characterized by transmission electron microscopy, scanning electron microscopy, zeta potential, and energy-dispersive spectroscopy.
