“…The majority of the oxides is represented by the iron oxide FeO with lower content of high-temperature cubic spinel CuFe 2 O 4 . It is known [39] that among many other methods, MeFe 2 O 4 spinels can be obtained via mechanical milling, powder metallurgy, solid state reactions, etc. High local temperatures and pressure are developed during magnetic pulse compaction that serve to the synthesis.…”

Bimetallic 73 wt.% Fe–Cu nanoparticles have been produced using electric explosion of two immiscible metal wires and then consolidated into disks using magnetic pulse compaction. The compacted disks have been characterized for phase composition, mechanical strength, and high-temperature steel ball-on-disk sliding friction. The sample possessed good flexural and compression strength. Friction and wear reduction were observed during sliding test at 400 °C, which was explained by intense tribosynthesis of cuprospinel CuFe2O4 nanoparticles, which served to reduce adhesion between the ball and disk.

“…The increasing trend observed in bond angles θ (1) and θ (2) (Table 5) suggests the strengthening of A-B interactions, while θ (3) , θ (4) and θ (5) are found to be not changed with increasing Ni 2+ concentration. However, deviation from linear increase/decrease in the values is due to the difference in the occupancy ratios of cations among tetrahedral (A) and octahedral (B) sites.…”

In this work, Ni substituted magnesium spinel ferrites having general formula Mg 1 − x Ni x Fe 2 O 4 (where x = 0.0, 0.1, 0.15, 0.2, 0.25 and 0.3) were synthesized by standard solid state reaction method. All the samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetometer (VSM), DC resistivity measurements. X-ray diffraction analysis confirmed the single spinel phase. The lattice constant decreased with increasing Ni content due to the difference in the ionic radii of Mg 2+ and Ni 2+ ions. The FT-IR spectra reveled two prominent frequency bands in the wave number range of 400 cm −1 to 600 cm −1 , which confirmed the cubic spinel structure of obtained compound and completion of chemical reaction. Magnetic studies revealed that the saturation magnetization increased with the substitution of Ni. The increase in magnetization was explained on the basis of distribution of magnetic and non-magnetic cations among A and B sites of the spinel lattice. A significant influence of cation distribution on DC electrical resistivity and activation energy was observed.

“…Magnetic materials are increasingly used in various scientific and technological processes (Sharma et al 2017;Kothawale et al 2019;Satheeshkumar et al 2019;Tsay et al 2019;Hua et al 2020). The use of such materials in adsorption processes makes them possible to significantly simplify the complicated procedure for separating powdered adsorbents from solution using an external magnetic field (Tatarchuk et al 2017(Tatarchuk et al , 2019aDeepty et al 2018). One of the environmental problems is the contamination of territories with radionuclides, originated from nuclear power plants.…”

Magnetic magnesium-zinc spinel ferrite Mg 1 − x Zn x Fe 2 O 4 (where x = 0.4, 0.6, and 0.8) was investigated as adsorbent for the efficient removal of Sr(II) ions and salicylic acid (SA) contaminants from aqueous medium. The characterization of ferrites was carried out using XRD, VSM, BET, SEM, and EDS. The surface charge of magnetic adsorbents was measured by the drift method. The determination of SA and Sr(II) ion concentrations in the solution phase was carried out by UFLC and complexometry, respectively. It was shown that varying of the Zn(II) content affected the adsorption capacities of magnesiumzinc ferrites. The increasing of zinc content from x(Zn 2+) = 0.4 to x(Zn 2+) = 0.6 increased the adsorption of Sr(II) ions from 50 to 65 mg/g, and then it was decreased to 36 mg/g for the sample with x(Zn) = 0.8. The Mg 0.4 Zn 0.6 Fe 2 O 4 sample demonstrated the maximum adsorption capacity of 74 mg/g. The adsorption isotherm for Sr(II) was fitted by the Dubinin-Radushkevich, Langmuir, Freundlich, and Sips models. The adsorption kinetics of Sr(II) was analyzed by PFO, PSO, and Elovich models. The adsorption kinetics of SA was also investigated. It was demonstrated that the Mg 0.2 Zn 0.8 Fe 2 O 4 sample exhibited 90% removal of salicylic acid from the water solutions. The results demonstrated that magnetic Mg-Zn ferrites with spinel structure are good sorbents for the removal of SA and Sr(II) ions from aqueous solution.
