“…These materials present a high permittivity and dielectric losses, leading to the EM attenuation. Materials with magnetic losses are often based on ferrites MFe2O4 with (M= Ni, Co, Cu, Zn, Mg …) [9][10][11] or metal carbonyls (for example carbonyl iron [12][13][14]). However, their high density (d > 2 g.cm -3 ) limits their use in a number of mobile or building applications [15].…”

“…Acetone, methanol, and ethanol have combustion temperatures of about 425, 375, and 350 degrees Celsius, respectively. S. R. Bhongale et al, 92 used the oxalate co-precipitation method to synthesise Mg x Cd 1-x Fe 2 O 4 (x=0, 0.2, 0.4, 0.6, 0.8, and 1.0) and analysed it using XRD, SEM, VSM, and FT-IR techniques. Synthesized ferrites have grain sizes ranging from 2 to 6.5 m. The authors found that as Mg 2+ content increases, the real component of permittivity (ἐ) drops and the dielectric loss tangent increases up to x=0.6, then decreases.…”

Ferrites have gained a lot of attention because of their diverse uses in domains including photocatalytic degradations, gas sensors, electronic devices, organic transformation catalysts, adsorption, and so on. This review focuses on cadmium ferrites and their numerous doped versions' production methodologies, characterization, and applications. The structural, electric, magnetic, and dielectric properties of cadmium ferrites are primarily influenced by the synthesis procedures and circumstances used during preparation. As a result, the main goal of this study was to provide the most often used synthesis processes, such as hydrothermal, co-precipitation, solvothermal, microwave-assisted, micro-emulsion, and solid state, as well as their benefits and drawbacks. Furthermore, the review focuses on the numerous characterization approaches used to investigate features such as optical, structural, magnetic, electric, and dielectric properties of cadmium ferrites. This analysis was further expanded to include applications in some of the most well-studied domains, such as photocatalysis and gas sensing.

“…Spinel ferrites nanoparticles (NPs) have received much interest because of their soft magnetic properties, low coercivity, moderate saturation magnetization, good chemical stability, and mechanical hardness [1] and promising applications such as high-density data storage, [2] rechargeable lithium batteries, [3] magnetic resonance imaging, [4] magnetic fluids, [5] microwave absorbers, [6] switching devices, [7] sensor technology, [8] catalyst, [9,10] and thermochemical water-splitting process. [11] They could be used as a catalyst and for pollutant removal through adsorption or photodegradation reactions.…”

The uniqueness of this work is the comparison of manganese ferrites/ polyaniline (Mn x Fe 3 À x O 4 /PANI) produced using K 2 S 2 O 8 as an oxidant for aniline with the efficacy of spinel manganese ferrite with various Mn 2+ ratios for the polymerization of aniline. The structural and morphological properties of the nanocomposites were characterized by thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), vibrating sample magnetometer (VSM), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), and Brunauer-Emmett-Teller (BET) techniques. XRD results confirmed the formation of a single-phase cubic spinel structure with a lattice constant of approximately 8.3 Å. The surface enriched by Mn 2+ exhibited an enhanced valence of +3 and +4, increased lattice oxygen content, facilitated ferrite reduction, and improved the oxidative performance of Fe 3+ . The saturation magnetization decreased with an increase in Mn +2 ratios and PANI contents. The nanocomposites exhibited excellent adsorption of Lanaset Brown B dye, which was investigated as a model textile dye. Various adsorption capacities (q max ) for the nanocomposites were calculated in a range of 122.39-215 mg/ g, depending on the synthesis conditions. Optimization parameters, such as pH, adsorbent dose, and initial concentration, as well as reusability, were described. The Langmuir isotherm is a better model for describing the adsorption process of the nanocomposites. An evaluation of thermodynamic parameters suggests the sorption process is feasible, spontaneous, and endothermic.
