“…Ilayas et al ventured into the application of La substituted NFO in the context of applications in supercapacitor. Their study unveiled the potential of La doped NFO electrodes as a potential candidate for energy storage applications such as supercapacitor [9]. Furthermore, several other researchers have noted significant alterations in the structural, magnetic and electrical properties of ferrites resulting from the substitution of RE elements [10,11].…”

The current research focuses on the synthesis of nickel spinel ferrite nanoparticles doped with rare earth elements via green synthesis-assisted sol-gel auto combustion method. X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), Raman spectra were carried to examine the development of phase, morphology, and crystal structure. Structural parameters, cation distribution, and lattice strain were determined through Rietveld analysis and Williamson-Hall (W-H) plots. Using the G-Fourier technique, the electron density mapping of Nickel nano-ferrites replaced with rare earth (Tb) elements was computed. Nickel-ferrites' room-temperature hysteresis curve was measured using a vibrating sample magnetometer (VSM). The insignificant hysteresis curve with small coercivity value and retentivity seen demonstrates the soft behavior. A thorough discussion was held regarding the impact of substituting non-magnetic ions on the coercivity, permeability, magnetic interaction constant, and Curie temperature of the synthesized ferrite. When terbium is added, the samples' saturation magnetization lowers because of spin canting phenomena and a decrease in particle size, which results in a decreased surface-to-volume ratio. Nanocrystalline ferrites replaced with rare earth elements have numerous advanced technical applications, including high-frequency devices and switching devices.

“…Application of nickel doped titanium oxide immobilized in earth clay as photocatalyst to destroy methylene blue indicator in aqueous solution showed its benefit in relation to economic cost and efficiency (Sharma et al, 2023). Synthesis of nickel ferrite to yield high performance electrode for supercapacitor was reported by Ilayas et al, (2023). On other occasion, Vinosha et al, (2021) investigated nickel substitution in cobalt ferrite nanoparticles to enhance magneto-optical, electrical, and acoustical properties.…”

Indonesia is a country rich in laterite mining especially in Celebes island and northern Moluccas. Laterite is a mineral rich with precious nickel. Nitric acid leaching has been used for nickel extraction from laterite under the influence of nitric acid concentration (2.0 M, 4.0 M, and 6.0 M) and leaching temperature (65oC, 70oC, and 75oC) during 60 min. at 300 rpm. The preliminary study aims to apply multiple linear regression (MLR) method to examine the dominant effect between acid concentration and leaching temperature on nickel extraction, and also Pearson correlation to study significant correlation between the variables involved (acid concentration, leaching temperature, and nickel concentration). The method and results is related to acid leaching at varied temperature set up as predictors and nickel concentration as dependent variable in the MLR equation using the enter method. The MLR method showed that acid concentration gave significant effect on nickel concentration, however, the leaching temperature showed no significant effect on nickel extraction at t ≤ 0.05. The Pearson correlation showed acid concentration correlated significantly with nickel concentration. The Kolmogrov-Smirnov (K-S) test showed normality for distribution of nickel concentration. The acid leaching method is potential for nickel extraction from laterite using extensive range of acid concentrations and leaching temperatures to improve nickel extraction.
