“…The residual plot of the experiments was used to investigate the scientific dispersion of experiments and their normal distribution ( Huo et al, 2022 ; Jiang et al, 2021 ). As shown in Figure 6 , the positive and negative levels are strong evidence for dispersion of the experiments on a regular basis.…”

For the first time, biocompatible and biodegradable Ta-metal organic framework (MOF)/polyether block amide (PEBA) fibrous polymeric nanostructures were synthesized by ultrasonic and electrospinning routes in this study. The XRD peaks of products were wider, which is due to the significant effect of the ultrasonic and electrospinning methods on the final product. The adsorption/desorption behavior of the nanostructures is similar to that of the third type of isotherm series, which showed mesoporous behavior for the products. The sample has uniform morphology without any evidence of agglomeration. Since the adsorption and trapping of gaseous pollutants are very important, the application of the final Ta-MOF/PEBA fibrous polymeric nanostructures was investigated for CH4 adsorption. In order to achieve the optimal conditions of experiments and also systematic studies of the parameters, fractional factorial design was used. The results showed that by selecting temperature 40°C, time duration 35 min, and pressure 3 bar, the CH4 gas adsorption rate was near 4 mmol/g. Ultrasonic and electrospinning routes as well as immobilization of Ta-MOF in the PEBA fibrous network affect the performance of the final products for CH4 gas adsorption.

“…The small remanent magnetization (M r , 2.88 emu/g) and coercivity (H c , 0.08 Oe) of CB Fe-MOF@Fe 3 O 4 NFC suggest that it has a suitable magnetic behavior with a saturation magnetization of M s , 11.1 emu/g, which suffices for magnetic separation by a conventional magnet. The magnetic behavior of the CB Fe-MOF@Fe 3 O 4 NFC was improved over that of previous catalysts (Zhao et al, 2022;Huo et al, 2022), and could be related to the physicochemical configuration of its final structure. These results support the hypothesis that CB Fe-MOF@Fe 3 O 4 NFC exhibit suitable behavior as an efficient catalyst in organic transformations.…”

“…Owing to their facile preparation, eco-friendly nature, and non-toxicity ( El-Boubbou, 2018 ; Xie et al, 2018 ; Ashraf et al, 2019 ), they have found extensive applications in drug delivery ( Duran et al, 2008 ), fluid transport ( Latham and Williams, 2008 ), hyperthermia ( Mornet et al, 2004 ), MRI (magnetic resonance imaging) ( Casula et al, 2011 ), and environmental remediation ( Lu et al, 2004 ). Some of the processes currently carried out by these heterogeneous catalysts include Rh(III)-catalyzed synthesis of dibenzo [b,d]pyran-6-ones from aryl ketone O-acetyl oximes and quinones via C–H activation and C–C bond cleavage ( Rezayati et al, 2016 ; Yang et al, 2022 ), hydrolysis of ammonia borane by highly active Fe 36 Co 44 bimetallic nanocluster catalysts ( Huo et al, 2022 ), and phosphate-modified Pt/CeO 2 catalysis for total oxidation of light alkanes ( Huang et al, 2022 ). Recently, the application of metal oxide MNPs, and particularly Fe 3 O 4 nanoparticles, has been the focus of many studies.…”

In this study, the recyclable heterogeneous cluster bud Fe-MOF@Fe3O4 ‘nanoflower’ composite (CB Fe-MOF@Fe3O4 NFC) was successfully synthesized using Fe(NO3)3·9H2O, 8-hydroxyquinoline sulfate monohydrate, and Fe3O4 nanoparticles by microwave irradiation. The as-prepared CB Fe-MOF@Fe3O4 NFC was characterized by X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDX), vibrational sampling magnetometry (VSM), and Fourier transform infrared spectroscopy (FTIR). The CB Fe-MOF@Fe3O4 NFC samples proved to have excellent catalytic activity. The activity of the CB Fe-MOF@Fe3O4 NFC nanocatalyst was explored in the synthesis of dihydropyrano[3, 2-c]chromene derivatives via a three-component reaction of 4-hydroxycoumarin, malononitrile, and a wide range of aromatic aldehyde compounds. Optimized reaction conditions had several advantages, including the use of water as a green solvent, environmental compatibility, simple work-up, reusability of the catalyst, low catalyst loading, faster reaction time, and higher yields.

Multifunctional magnetic composite nanoparticles (NPs) with antibiotics have demonstrated symbiotic effects because of their promising antimicrobial properties. The antimicrobial agent reduces side effects and dosage, and increases drug delivery efficiency. In this study, SiO2 coated over Fe3O4 magnetic nanoparticles (MNPs) were prepared by a solvothermal method. The MNPs were characterized by using X-ray diffraction (XRD), transmission electron microscopy (TEM), ultraviolet-visible spectroscopy (UV-vis), and Fourier transform infrared spectroscopy (FTIR). The antimicrobial tests were carried out using the disk diffusion method. The electrochemical sensing was investigated by cyclic voltammetry with varying As(III) concentrations from 1–10 ppb. The microstructural results showed the formation of spherical-shaped Fe3O4@SiO2 MNPs with 15–30 nm diameters. UV-vis results showed that Fe3O4 NPs promote visible light absorption of Fe3O4@SiO2 MNPs because of well-structured and unvarying shell thickness which is beneficial for the absorption of organic dyes. With an increase in the concentration of As(III), there was a shift in potential and an increase in oxidation peak current, showing the electrocatalytic capacity of the modified electrode. The SiO2 deposited on Fe3O4 displayed an admirable microbial operation. These Fe3O4@SiO2 MNPs are easily absorbed by cells and have the potential to influence bacterial cells both within and outside of the cell membrane, making them an intriguing candidate for use in a variety of biological applications in the future.
