[ 1 ] - An efficient facile and one-pot synthesis of 2-arylsubstituted benzimidazole derivatives using 1-methyl-3-(2-oxyethyl)-1H-imidazol-3-ium-borate sulfonic acid as a recyclable and highly efficient ionic liquid catalyst at green condition
1-Methyl-3-(2-oxyethyl)-1H-Imidazol-3-ium-Borate Sulfonic Acid ([MOEI]-BSA) was easily prepared and used as a new and highly efficient solid acid catalyst for the synthesis of benzimidazole derivatives with high isolated yields. Various substituted benzimidazoles were synthesized by a combination of o-phenylenediamines and aldehydes in the presence of [MOEI]-BSA with excellent yields in water a...
[ 2 ] - Turmeric extract as a biocompatible inhibitor of mild steel corrosion in 3.5% NaCl solution
Corrosion inhibitory impacts of turmeric with concentrations of 200-800 ppm on the electrochemical behavior of mild steel were studied in the medium of NaCl 3.5% using several techniques such as electrochemical impedance spectroscopy (EIS) and polarization. Scanning electron microscopy (SEM) was used for analyzing the surface of mild steel after 24 hours of immersion in the electrolyte solution...
[ 3 ] - Effective Parameters on Removal of Rhodamine B from Colored Wastewater by Nano polyaniline/Sawdust Composite
Background and purpose: Contamination of groundwater with colored and toxic wastewater causes many environmental problems and has adverse effects on human health. This study aimed at coating a nano polyaniline polymer layer on the surface of sawdust and preparing polyaniline sawdust composite (Pan/SD) via chemical polymerization of aniline monomer onto sawdust in aqueous solutions and removal o...
[ 4 ] - Adsorption of Metronidazole drug on the surface of nano fullerene C60 doped with Si, B and Al: A DFT study
In this research, the quantum mechanics calculations were carried out to elucidate the adsorption behavior of metronidazole drug on the surface of pristine as well as doped C60 fullerene with Si, B and Al using density functional theory (DFT) at B3LYP/6-31G(d,p) level. After optimization of the structures, various parameters such as HOMO and LUMO energies, gap energy, adsorption ener...
[ 5 ] - Synthesis of activated carbon/zinc oxide nanocomposite from rapeseed plant waste by green chemistry method, evaluation of its performance in Methylene Blue pigment removal and optimization of influencing parameters using design expert
Background and Objective: Due to the water shortages and the presence of industrial pollutants in water resources, wastewater treatment, especially colored wastewater, is essential. The aim of this study was to treat wastewater containing Methylene Blue dye using activated carbon nanocomposite/zinc oxide nanoparticles (ZnO/AC) obtained from canola oil waste by green method. Materials and Metho...
