“…The obtained SAR value is 253.7 ± 27.3 W/g. This value is very high compared to the reported values of Fe 3 O 4 [43,45] and indicates that this material is likely to be very suitable for application in tumor magnetic hyperthermia.…”

In this work, a very facile one-pot hydrothermal synthesis approach has been developed for the preparation of ultrathin magnetite nanoplates. The hydrothermal procedure was performed by aging ferrous hydroxide under anaerobic conditions, which is known as Schikorr reaction. Ethylene glycol (EG), which was introduced to the reaction as another solvent, played a critical role in the formation process of these nanoplates. Typically, hexagonal Fe3O4 nanoplates with a thickness of 10 to 15 nm and a side length of 150 to 200 nm have been synthesized with EG/H2O = 1:1 in experiments. Our data suggest that the thickness of Fe3O4 nanoplates decreases, and the shape of the nanoplate becomes more irregular when the concentration of EG increases. The as-prepared Fe3O4 nanoplates were highly crystallized single crystals and exhibited large coercivity and specific absorption rate coefficient.

“…The mean SAR value of the oleate coated nanoparticles was about 14 W/g at a low field amplitude of 15.9 kA/m and frequency of 62 kHz. Rashad et al managed to obtain similar results with a lower particle concentration, although a much larger magnetic field with 41.5 kA/m amplitude and 160 kHz frequency was employed [50].…”

We report a simple and low cost methodology to synthesize sodium oleate coated magnetite nanoparticles for hyperthermia applications. The system consists of oleate coated magnetite nanoparticles with large susceptibility (1065 emu/gT), induced by the dipolar inter-particle interaction, with a magnetic core diameter in the 6 nm-12 nm size range. In aqueous medium, the nanoparticles agglomerate to form a monodisperse system, exhibiting a mean hydrodynamic diameter of 60.6 nm74.1 nm, with a low average polydispersity index of 0.12870.003, as required for intravenous applications. The system exhibits promising efficiency for magnetic hyperthermia, with a specific absorption rate of 14 W/g at a low field amplitude of 15.9 kA/m and frequency of 62 kHz. In a 50 mg/mL density in 1 mL, the temperature rises to 42.5 1C in 1.9 min.

“…Different magnetite nanoparticles can be synthesized by different techniques like coprecipitation [29][30][31][32][33], hydrothermal [34], thermal decomposition [35][36][37], and sol-gel [38,39]. These technologies have the potential to be beneficial in the preparation of various forms of Fe 3 O 4 .…”

In recent years, the application of nanoadditives in biofuels is gaining much attention due to their increase in thermophysical properties such as high surface area, thermal conductivity, and mass diffusivity. However, lack of stability, high additive cost, and difficult recovery from engine exhaust are the high-priority and demanding characteristics, which may be chosen by many researchers. In this regard, the most promising nanoadditives are magnetite nanoparticles, having a high-specific area, strong magnetic response, control over the particle size and, most importantly, easy and rapid separation from exhaust gas by applying external magnetic bars. Moreover, it can be easily diluted into biodiesel, and thus, it can collect the advantages of biodiesel in water emulsion. From the literature survey, it is found that there is a lacuna in the synthesis and performance of magnetite nanofuels for internal combustion engine applications. Thus, the present study aims to epitomize the research findings related to the synthesis, characterization, stability, and properties of biodiesel/diesel-based fuels blended with magnetite nanoparticles and the influence of the magnetite nanofuels on engine performance. The study shows that the addition of nanoparticles to biodiesel has positive effects in reducing harmful emissions such as carbon black, smoke opacity and NOX, with improved thermal efficiency and fuel consumption.
