In the past decade, numerous longitudinal studies have explored green chemistry and its applications in nanoparticle synthesis due to the toxicity associated with traditional methods. Among the various techniques for nanoparticle synthesis, the use of plant extracts in green synthesis has recently gained significant popularity. Green methods are particularly suitable for large-scale nanoparticle synthesis, offering […]
Magnetic nanoparticles (MNPs) were treated with dodecyl sulfate (DS) and dodecanol (DO) to enhance their affinity for lipids. Various methods, such as X-ray powder diffraction (XRD), scanning electron microscopy (SEM), vibrating sample magnetometery (VSM), thermal gravimetric analysis (TGA), and FTIR spectroscopy were employed to analyze and characterize these modified MNPs. The functionalized MNPs were employed […]
Favipiravir (FVP) was one of the promising medications for the treatment of Covid-19 patients. There are limited studies on the electrochemical performance of FVP. Hence it is interesting to study the electrochemical detection of FVP by cyclic voltammetry (CV), differential pulse voltammetry (DPV) and chronoamperometry. The G/In2O3 nanocatalyst was prepared by precipitation method and applied […]
One of the industries that uses huge volumes of water is the textile sector, which generates a lot of wastewaters. Electrocoagulation (EC), an environmentally friendly method, has been utilized to remediate textile dyeing effluent. The goal of this work is to compare the catalytic activity of Ti with Al using two sets of experiments (Al-Ti, […]
Levulinic acid (LA) is a valuable renewable resource that can serve as a versatile biomassderived building block for the synthesis of organic chemicals, providing a sustainable alternative to depleting fossil fuel resources. Catalytic esterification of LA with alcohol yields levulinate esters, which find numerous applications including perfumes and fuel additives. In this study, the performance […]
Cu-catalysis was employed to create numerous (E)-5-bromo-N-aryl oxindole nitrones with satisfactory to excellent coupling efficiencies. This process involved the reaction of N-unprotected 5-bromoisatin-3-oximes and aryl-boronic acid derivatives under mild reactive conditions. Remarkably, the reaction exhibited tolerance towards several aryl-boronic acids containing diverse functional sensitivity subgroups (73% to 97% yields and 2 to 6 h). Extensive […]
As a natural-based catalyst, nano-Fe3O4@dextrin/Si(CH2)3/DABCO was fabricated and characterized with different analytical methods such as field emission scanning electron microscopy, X-ray diffraction, Fourier-transform infrared spectroscopy, X-ray mapping, energy-dispersive X-ray spectroscopy, thermogravimetric analysis, and vibrating sample magnetometer. The mentioned new natural magnetic nanocatalyst was employed for the three-component synthesis of tetrahydrobenzo[b]pyrans and spirooxindoles from aromatic aldehyde […]
In this work, an efficient method for the construction of N-amino-2-pyridone analogs was performed using the condensation of aldehyde, malononitrile and cyanoacetohydrazide through Fe3O4@aminopropyltriethoxysilane-terephthaldehyde-melamine (Fe3O4@APTES-TA-MA) as an efficient recyclable magnetic covalent organic framework nanocatalyst in ethanol at reflux conditions. Fe3O4@APTES-TA-MA was characterized via FT-IR, EDS, SEM, TEM, VSM, and TGA methods. The average size of […]
