“…As shown in Figure d, lattice strain needs to be observed as it is caused by the increase and decrease in the d -spacing having a linear effect on the early and late 2θ positions. In a related study, the strain mechanism for the elastic properties of the material was linked to the energy density of the unit cell . The change in lattice size will also provide opportunities for outer atoms to fill, substitute, or sit in suitable positions, thus triggering changes in the magnetic saturation and coercivity properties of the material .…”

Efforts to produce microwave absorber materials that are inexpensive and environmentally friendly have become a means of greening the environment. The breakthrough can be focused on industrial waste and natural materials for functional purposes and how to enhance their performance. We successfully synthesized nickel slag/laterite soil (NS/LS) and nickel slag/iron sand (NS/IS) nanocomposites using a simple mechanical alloying technique, and the electromagnetic (EM) wave absorption capacities of the nanocomposites were measured using a vector network analyzer. The structural properties of the nanocomposites were analyzed by X-ray diffraction spectroscopy, where the results of the analysis showed that NS/IS has the largest crystallite size (15.69 nm) and the highest EM wave absorption performance. The optical properties of the nanocomposites were determined from their Fourier transform infrared spectra using the Kramers–Kronig relation. As determined through a quantitative analysis of the optical properties, the distance between the longitudinal and transversal optical phonon wavenumber positions (Δ(LO – TO) = 65 cm–1) is inversely proportional to the reflection loss. The surface morphologies of the nanocomposites were analyzed by scanning electron microscopy, and the particle diameters were observed by binary image and Gaussian distribution analyses. The nanocomposite surface exhibits a graded-like morphology, which indicates multiple reflections of the EM radiation, consequently reducing the EM interference. The best nanocomposite for an attenuated EM wave achieved a reflection loss of −39.14 dB at 5–8 GHz. A low penetration depth has implications for the electrical charge tuning of the storage and composite magnets. Finally, the EM absorption properties of NS/IS and NS/LS indicate a 2-mm-thick environmentally friendly nanocomposite for EM absorption.

Co2Fe2O4 NPs were made using the sol‐gel ignition technique employing citric acid (C6H8O7.6H2O) as a reducing agent to oxidizing agent with a ratio of 1 : 3. A thorough study of the effects of divalent Zn2+ and trivalent Y3+ ion on their structural, Infra‐red, morphological, magnetic, DC‐electrical, optical, and photocatalytic activity. All of the samples have crystallized to a cubic spinel structure with a single phase space group Fd3m, according to the analysis of the XRD pattern consisting of the intense reflections (220), (311) (222), (400), (422), (511), (440), (533), and (444). Transmission electron microscopy (TEM) suggested the particle size range of ~27 nm; and demonstrates the agglomerations on the tip of MNPs, which are ideal for increasing surface area, and infrared study verifies the spinel structure. With a decrease in the hysteresis loop for the Zn−Y ligand, the magnetic hysteresis loops demonstrate a ferrimagnetic character. With Zn−Y, magnetic characteristics are noticeably affected; saturation magnetization (Ms) 70.9133 to 59.2148 emu/g; and coercivity (Hc) 1900.30 to 193.96 Oe both exhibit a decrease. The DC‐electrical resistivity image reveals the CFMNPs′ semiconducting nature and the optical energy bandgap demonstrates a decrease from their original state. The MB dye's decolorization demonstrates the amazing deterioration in a short amount of time 20 to 80 minutes range was observed to be 35.88, 61.92, 76.40, and 94.07 %.
