“…Characteristic peak of the MCM-41 was disappeared at 2θ = 2.5-10° in case of Cu (I). These results are consistent with studies by other researchers, probably due to lower thermal and chemical stability [21,[39][40][41][42].…”

In the present study, to enhance removal of quinoline contaminants using natural active component, vanillin was loaded onto the MCM-41 (Mobile Component Material) nanoparticles in a simple way. The product was divided into two parts, which were improved by Copper(I) and Copper(II) salts. Promoted synthetic nanocatalysts (Cu(I)/Van./MCM-41, and Cu(II)/Van./MCM-41) were characterized using X-Ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM), Energy-Dispersive X-Ray Spectroscopy (EDS), Mapping, Fourier-Transform Infrared Spectroscopy (FTIR), and BET/BJH (Brunauer-Emmett-Teller (BET) and Barret-Joyner-Halenda (BJH)) techniques. To reach optimal conditions, experimental design was performed using Response Surface Methodology (RSM). The experiments were done with the aid of nanocomposites, in presence of ultraviolet radiation without any auxiliary oxidants. Degradation percentages were measured by an Ultraviolet (UV) spectrophotometer. The products were identified using Gas Chromatography-Mass (GC-Mass) technique, and some mechanisms for quinoline removal were proposed. The results indicated that Cu (I) showed better performance in enhanced removal of quinoline than Cu(II).

“…Generally, the microbial inhibition potential was higher against the Gram-negative bacteria than the Gram-positive bacteria and fungi due to the absence of a peptidoglycan layer in the Gram-negative bacteria, whereas the Gram-positive bacteria had a thick peptidoglycan layer and the fungi were more resistant to environmental conditions and had a strong chitinous membrane layer for protection [18,37]. These results were contrary to previous reports of NiO-NPs synthesized through biogenic/phytogenic preparation [4,[15][16][17]. of electrons between the reactants and formed products is responsible for the antioxidant property of the phytogenic NiO-NPs [25,36].…”

“…The biosynthetic process is gaining interest since it avoids high costs, several synthesis steps, usage of toxic chemicals, and harsh atmospheric conditions for reduction and stabilization. NiO nanoparticles are prepared using different plant leaf extracts such as Azadiricta indica, Calotropis gigantea, Agathosma betulina, and Aegle marmelos [4,[15][16][17]. The leaf extracts from natural sources of polysaccharides, flavonoids, terpenoids, polyphenols, glycosides, proteins, and vitamins act as reducing and capping agents in the preparation of nanoparticles [18].…”

In the present study, economically viable NiO nanoparticles were produced by biogenic preparation using stevia leaf broth and their in-vitro antioxidant and antimicrobial activities were evaluated. The properties of the prepared NiO nanoparticles were confirmed by analytical techniques such as Ultraviolet-Visible (UV-Vis), X-ray diffraction (XRD), FE-SEM, and Fourier transform infrared spectroscopy (FTIR) analyses. Morphological studies using scanning electron microscopy (SEM) and transmission electron microscopy (TEM) showed that the size of synthesized nanoparticles ranged from 20 to 50 nm, most of which were spherical and few of which were agglomerated. The role of the biological moieties, which reduce and cap the nanoparticles, was studied using FTIR analysis. The prepared nanoparticles strongly inhibited gram-negative bacteria, which is a camper with gram-positive bacteria and fungi. Furthermore, it performs an effective in-vitro activity through α,α-diphenyl-β-picrylhydrazyl (DPPH) reduction. Thus, it can be concluded that the effective and easy green synthesis process used for NiO nanoparticles provides potential antimicrobial agents against multidrug-resistant microbes.

“…Moreover, the formation of CuO nanoparticles were detected by analyzing reaction solution using UV-visible spectroscopy in the wavelength of 200-800 nm regions. [27][28][29][30][31][32][33][34] The UV-Visible spectrum results demonstrated the highest absorption peak at 276 nm which clearly indicated that the formation of CuO NPs. The quadratic BBD based response surface model expresses the CuO NPs absorbance as a utility of time, temperature and extract quantity.…”

CuO NPs were planned to synthesize using Abutilon indicum (A. indicum) leaf aqueous extract as an ecofriendly source without any harmful chemicals like other physio‐chemical methods. The ecofriendly synthesized shape controlled CuO NPs is further processed for several characterization tools to identify the morphology and its physical nature. Synthetic methodology was optimized using RSM technique. The characterization output results in crystalline rod shaped CuO NPs with 23±2 nm. Further, CuO NPs were screened for degradation study against harmful azo dye. The results indicates that the higher degradation rate in both the extract and synthesized CuO NPs, around 95.48 % degradation of dye using CuO NPs was identified using Pseudo first order reaction kinetics are being clearly stated in this manuscript. Furthermore, examination of CuO NPs in the direction of photocatalytic behaviour was optimized through taguchi methodology.
