“…The magnetic squareness ratio value at and above 0.5 corresponds to materials having single magnetic domain size and the value below 0.5 implies to materials with the multi domain structure. So according to that the prepared nickel ferrite nanoparticles exhibits multi domain structure with orientation changes with the applied magnetic field facilitated by the movement of domain walls [40][41][42][43].…”

“…Tony and his group (Dhiwahar et al 2021) examined the improved photocatalytic decomposition of rhodamine B with visible light employing Ni-doped copper ferrite spinel nanostructures. The Kubelka-Munk model was applied to evaluate the bandgap energy of Cu 1-x Ni x Fe 2 O 4 and observed to fluctuate from 2.30 to 2.06 eV.…”

The rapid urbanization and industrialization is causing worldwide water pollution, calling for advanced cleaning methods. For instance, pollutant adsorption on magnetic oxides is efficient and very practical due to the easy separation from solutions by an magnetic field. Here we review the synthesis and performance of magnetic oxides such as iron oxides, spinel ferrites, and perovskite oxides for water remediation. We present structural, optical, and magnetic properties. Magnetic oxides are also promising photocatalysts for the degradation of organic pollutants. Antimicrobial activities and adsorption of heavy metals and radionucleides are also discussed.

“…The basic methods of ferrite synthesis are the sol-gel method, the co-precipitation method, the hydrothermal method, and solid-state reactions. Additionally, one can mention the combustion synthesis method used, for example, to produce copper ferrites, which consists in burning the solutions with L-arginine [31] and citric acid [32] as fuel. In this case, the formation of nanoparticles with a p-n heterojunction occurs at high temperatures in the vapor phase but is complicated by a number of chemical reactions with the formation of byproducts that contaminate the target product.…”

We have prepared a composite thin coating by incorporation of CuFe2O4/Cu2O/CuO nanoparticles in polymethyl methacrylate (PMMA) matrix by using the solution casting method. The electrical explosion of two twisted wires (EETW) was used to obtain multicomponent CuFe2O4/Cu2O/CuO nanoparticles with an average particle size of 20–70 nm. The microscopic studies showed that the nanoparticles in the composite coatings are evenly distributed. However, nanoparticles are strongly agglomerated as the powder concentration in the coating increases to 5 wt.% and 10 wt.%, as the size of particle agglomerates increases to 50 and 100 μm, respectively. Therefore, nanoparticles were pre-treated with ultrasound when introduced into the PMMA matrix. The thermal stability of the composite coating does not change with the introduction of CuFe2O4/Cu2O/CuO nanoparticles in the amount of 5 wt.%. The inclusion of nanoparticles in the PMMA matrix significantly enhances its antibacterial activity. The addition of 5 wt.% nanoparticles inhibited the growth of E. coli by 100% and the growth of MRSA by 99.94% compared to pure PMMA already after 3 h of exposure of bacteria on the surface of the composites. This research provides an easy-to-manufacture and cost-efficient method for producing a CuFe2O4/Cu2O/CuO/PMMA composite coating with a broad application as an antibacterial material.
