“…It has several advantages over the reported studies which can be seen in table 2. The superparamagnetic iron oxide nanoparticles (SPIONs) were synthesized using a co-precipitation method described before 55,56 were dissolved in deionized water (20 mL) under an inert atmosphere to get a homogenous solution.…”

In this work, a novel magnetic organic-inorganic hybrid catalyst was fabricated by encapsulating magnetite@silica (Fe3O4@SiO2) nanoparticles with Isinglass protein collagen (IGPC) using epichlorohydrin (ECH) as crosslinking agent. Characterization studies of the prepared particles were accomplished by various analytical techniques specifically, Fourier transform infrared (FTIR) analysis, scanning electron microscopy (SEM), transmission electron microscopy (TEM), vibrating sample magnetometry (VSM), energy dispersive X-ray (EDX), X-ray diffraction (XRD), and Brunauer−Emmett−Teller (BET) analysis. The XRD results showed a crystalline and amorphous phase which contribute to magnetite and isinglass respectively. Moreover, the formation of the core/shell structure had been confirmed by TEM images. The synthesized Fe3O4@SiO2/ECH/IG was applied as bifunctional heterogeneous catalyst in the synthesis of spirooxindole derivatives demonstrating excellent catalytic properties, stability and recyclability.

Recently, nanofluids are introduced in the power utilities for the dielectric performance enhancement of power transformer oil. The compactness and fault improvement of the power transformers has resulted in the necessity of next-generation insulating fluid with inflated dielectric properties. This paper investigates the dielectric performance of the novel ester oil-based magnetic nanofluids with different nanoparticles under different electric stress conditions. Two biodegradable fluids used as the base liquid for the experiment are synthetic ester oil and natural ester oil while three magnetic nanoparticles used to synthesize nanofluids are iron (II, III) oxide, cobalt (II, III) oxide, and iron phosphide. The concentrations of the nanoparticles are varied to optimize the characteristics of the prepared nanofluids. The dielectric breakdown and relative permittivity of the nanofluids have been experimentally investigated. Further, the breakdown predictions have been performed using Weibull statistical distribution-based regression analysis. The experimental results show the improvement in the characteristics of prepared nanofluids with the change in nanoparticle concentration as compared with the host fluids.

Nowadays, environmentally friendly lubricants are developed to meet the standards of biodegradability, toxicity and bioaccumulation potential that reduce the adverse consequences to the aquatic atmosphere compared to conventional mineral based lubricants. In this study, an attempt made to enhance the feasibility of utilizing the Mustard oil as a commercial lubricating agent by homogeneously dispersing MWCNTs as an additive. The average crystallite size, surface morphology and elements of MWCNT are characterized through XRD, SEM, EDS and FTIR techniques, respectively. The surface deformation rate of matrix material (Mg) lubricated by Mustard oil and different weight fractions of MWCNT-Mustard oil nanofluid are estimated through Nanoindentation technique. The hardness, Young's modulus and AFM topography of the interacting surface infers that the dispersed MWCNT significantly enhance the lubricating properties of Mustard oil through micro-chipping and micro-softening effect.
