“…The primary particles have a radius of approximately 2.5 nm, and the secondary structures form clusters that have a radius of approximately 8 nm when compared with the results from the SANS data. These results are in a good agreement with the work by Giri and coworkers in which the TEM photographs of their Mn 0.4 Fe 2.6 O 4 nanoparticles showed nearly a spherical shape with a radius of approximately 12 nm and nanoclusters [39]. In addition, Fig.…”

A series of Mn x Fe 3−x O 4 (0 ≤ x ≤ 1) nanoparticles was successfully synthesized via a simple coprecipitation method. The starting material was a natural magnetite purified from local iron sand. Crystallite nanoparticles were produced by drying without using a high calcination temperature. Rietveld analysis of the X-ray diffractometry (XRD) data for all samples demonstrated that the Mn ions partially substituted the Fe ions in the spinel cubic structure of the Fe 3 O 4 to form Mn x Fe 3−x O 4 phases. We applied two lognormal spherical and single mass fractal models to the analysis of the small-angle neutron scattering (SANS) data and revealed that the primary Mn x Fe 3−x O 4 particles ranged in size from 1.5 to 3.8 nm and formed three-dimensional Darminto

“…Nanoferrites with belowcritical grain size at room temperature are characterized by superparamagnetism, low Curie temperature, and high magnetic flux density. These characteristics have enabled the use of nanosized magnetic materials in biomedicine (e.g., as bioseparators), drug delivery systems, medical diagnostics, and cancer thermotherapy [5][6][7]. Due to the new applications of ferrites ways of synthesizing them, other than the ceramic method, such as the sol-gel [8,9], the precipitation [10,11], the mechanochemical [12,13], the hydrothermal [14,15], the combustion [16][17][18][19][20], and the microemulsion methods [21,22], are being widely investigated.…”

Mn-Zn ferrites were obtained by the sol-gel autocombustion methods. The effect of the precursor used in the sol-gel autocombustion synthesis on the ferrite's microstructure was examined. The as-obtained powders were characterized by XRD, FTIR, SEM, and TG/DTA. All ferrite powders obtained from different organic precursors, after gel autocombustion, were pure spinel phase, without secondary phases. The average crystallite size, estimated from Scherrer equation, was the smallest for ferrite obtained from a mixture of fuels/precursors (citric acid and EDTA). This ferrite powder has sponge-like microstructure with large pores, but it is less agglomerated than the material obtained from glycine as the fuel.

“…[46,135] The presence of multiple bond geometry on the carbon chains also influences the FF stability. In the case of oleic acid (C 18 ), a cis double bond in the middle of the oleic tail forming a kink is expected to enhance the stability.…”

“…[310] However, the Co 2 + -substituted ferrite system was observed to be more toxic than Mn 2 + -substituted ferrites, which causes concern for their in vivo applications. [46] Among the various types of inorganic magnetic materials, iron oxides (Fe 3 O 4 and g-Fe 2 O 3 ) are the most commonly investigated ones since Fe ions are added to the body's iron stores, which are used to produce hemoglobin. [355] The most necessary criterion for using FF in vivo is the biocompatibility of its constituents.…”

Ferrofluids (FFs) or magnetic nanofluids are incredible smart materials consisting of ultrafine magnetic nanoparticles suspended in a liquid carrier medium, which exhibit both fluidity and magnetic controllability. Studies involving the dynamics and physicochemical properties of these magnetic nanofluids are an interdisciplinary area of research attracting researchers from different fields of science and technology. Herein, a comprehensive Review on the different aspects of FF research is presented. First, the synthesis and stabilization of various types of FFs are discussed followed by their physicochemical features such as polydispersity, magnetic behavior, dipolar interactions, formation of chainlike aggregates, and long‐range ordering. The Review also details the rheological and thermal properties, dynamic instabilities, phase behavior, and particle assemblies in FFs to form complex multipolar geometries, photonic nanostructures, labyrinth structures, thin films, and droplets. Many important characterization techniques for probing FF properties are also briefly discussed, and the numerous innovative applications and future prospects of FFs are outlined.
