“…Therefore, the particle size distribution must be precisely adjusted to obtain the appropriate induction heating properties (Murase et al 2011). Although various methods for preparing the magnetic particles with different diameters have been proposed so far (Iljinas et al 2005;Iwasaki et al 2010;Jing et al 2012;Mizutani et al 2010;Nemati et al 2017), it is hard to precisely adjust the particle size distribution, which may lead to insufficient control of the induction heating properties. In contrast, our results demonstrate that the induction heating properties of Gdsubstituted Mg-Zn ferrites can be relatively easily controlled by the metal composition compared with the particle size.…”

Gadolinium-substituted magnesium-zinc ferrite (Mg x Zn 1-x Gd y Fe 2-y O 4 ) nanoparticles with different metal compositions for x between 0 and 1 and y between 0 and 0.06 were synthesized via coprecipitation of metal hydroxides, followed by calcination. Their crystal structure was characterized via X-ray diffraction analysis, confirming that the Gd-substituted Mg-Zn ferrite samples had a single-phase spinel structure. The metal composition significantly affected the crystal structure, including the lattice parameters and crystallite size. Scanning electron microscopy (SEM) showed that the ferrite samples had a diameter of approximately 50-200 nm. Furthermore, the temperature rise in an alternating magnetic field was measured, and the magnetic induction heating properties were evaluated using the specific absorption rate (SAR) determined from the temperature profile. The SAR significantly varied depending on the compositions of x and y. When x = 0.5 and y = 0.02, the SAR was found to be at maximum. This reveals that the compositions can control the magnetic induction heating properties. The results suggest that Gd-substituted Mg-Zn ferrite nanoparticles are promising candidates for magnetic hyperthermia applications.

“…The synthesis of iron oxide nanoparticles of controlled shapes has attracted much attention because the physical and chemical properties depend strongly on particles size and morphology. As reported above, recently several chemical methods are employed to synthesize iron oxide nanoparticles such as sol-gel, hydrothermal, solid state, wet milling, pyrolysis and microemulsion [30][31][32][33][34][35][36][37]. The synthesis method plays a key role in determining the morphology, particles sizes, and shape.…”

“…Using magnetic metal oxides for the removal of heavy metals and dyes offers several advantages such as low cost, ease of synthesis, high adsorption capacity, ease of separation from the treated solution using magnet, and regenerability [25]. Several methods can be employed for preparing magnetic metal oxides such as co-precipitation [26], sol-gel [27], hydrothermal [28,29], spray pyrolysis [30], solid state reaction [31], electrochemical [32], and chemical vapor deposition [33]. The pechini sol-gel method for preparing magnetic metal oxides offers several advantages, such as low crystal size, tailored morphology, low cost, scalability, and high adsorption properties [23,25].…”

Safranine T dye causes health problems such as skin and respiratory irritations. Hence, the safranine T dye was efficiently removed from aqueous media employing a simply synthesized manganese ferrite (MnFe2O4) nanoadsorbent. The synthesis of manganese ferrite nanoparticles was carried out by the pechini sol–gel approach using tartaric acid to serve as a chelating agent in addition to 1,2-propanediol to serve as a crosslinker. The TEM analysis showed that the shape of MnFe2O4 nanoparticles is semi-spherical, with an average particle size of 19.32 nm that coincides well with that measured from the XRD (18.89 nm). Further, the several factors that influenced the removal process of safranine T dye were examined, such as time, dye concentration, pH, and temperature. The ideal experimental conditions that achieved the highest safranine T dye removal percentage are pH 8, 80 min, and 298 K. The maximum adsorption capacity of MnFe2O4 nanoparticles towards safranine T dye equals 334.45 mg/g. The removal process of safranine T dye by manganese ferrite nanoparticles was chemical, exothermic, and well defined through the Langmuir equilibrium sorption isotherm in addition to the pseudo-second-order model. The synthesized manganese ferrite nanoparticles have the ability to be reused many times without losing their efficiency.
