The structural, optical, electrical and humidity sensing properties of Cu–Mg–Zn ferrites with rare earth element doping were investigated. Single-phase cubic spinel structure was confirmed via X-ray diffraction (XRD), and the crystal size ranges from 22.12 to 63.17 nm according to the Scherrer formula and from 25.66 to 67.46 nm according to the Williamson–Hall method. Porous structure and elemental characterization of the samples were investigated by scanning electron microscopy (SEM). The optic band gap varies between 2.21 and 2.49 eV. Electrical measurements were conducted in the frequency range of 1 Hz–20 MHz and temperature range of 25–400 °C. It has been determined that the dielectric results are consistent with the Maxwell–Wagner method and exhibit a non-Debye relaxation model, as observed from the Nyquist plots. At a minimum frequency value of 1 Hz, the dielectric constants for pure, Ce, Sr, and La samples are 9 × 10⁴, 5 × 10⁴, 1 × 10⁸, and 2 × 10⁵ at 25 °C, and 1.85 × 10⁸, 1.34 × 10⁸, 1.15 × 10¹⁰, and 4.4 × 10⁸ at 400 °C. In the same order, for the maximum frequency value of 20 MHz, the dielectric constants at 25 °C are 169, 166, 3799, and 60, while at 400 °C they are 734, 624, 12108, and 774. The La doped sample's low dielectric loss makes it suitable for high-frequency applications. Humidity measurements were performed at room temperature and in the 5%–95% relative humidity range. The humidity properties of the samples were investigated through humidity mapping, sensitivity, hysteresis, and long-term stability tests. Compared to other samples, the results indicate that Ce exhibits better humidity performance with 99% sensitivity and the highest repeatability (91.2%).

Biosorption could be a promising method for adsorbing REEs onto microalgae, but biomass immobilization and light delivery challenges remain. It was recently shown that REEs biosorb 160% more on algal biofilms than suspended biomass due to the extracellular polymeric substance (EPS) matrix that grows abundantly in biofilms. In this work, we present findings on biosorption selectivity for different REEs in sulfate solutions. The maximum adsorption capacities of <em>Euglena mutabilis</em> suspensions and biofilms were determined for a mixed REE sulfate solution at an equimolar initial concentration range of 0.1–1 mol/L of each REE ion. The highest adsorption capacities for the suspension are for Sm and Eu which are 57% and 46% higher, respectively, compared to the average REE adsorption capacity. The biofilms also preferentially adsorb Sm, Eu, Yb and Lu at 0.035, 0.033, 0.033, and 0.031 mmol/g, respectively. The impact of dissolved divalent ions of Ca, Mg, and Fe on REE adsorption was also assessed. When Ca and Mg are added in equimolar amounts to 0.1–1 mmol/L solutions of equimolar La, Eu, and Yb sulfate, the amount of REEs adsorbed onto suspensions increases by 30% while when Fe is added, it decreases by 10%. No change is observed in biofilms except when Fe is added resulting in a reduction of the adsorption capacity by 40%.
