Summary: Superparamagnetic iron oxide nanoparticles (SPIONs) play a dominant role in various biomedical applications, including magnetic separation, drug delivery, diagnostics, and hyperthermia treatments. In this study, superparamagnetic nanoclusters (SP-NCs) with high unit magnetization and diameters up to 400 nm were synthesized using conventional or microwave-assisted solvothermal methods. The choice of synthesis route and capping agent significantly influenced the particle size, SP-NC size, surface chemistry, and magnetic properties. The SP-NCs were then coated with a silica shell doped with a fluorophore to provide fluorescence properties and high stability. The heating efficiency studies demonstrated the potential of these synthesized SP-NCs in hyperthermia treatment. The enhanced magnetically-active content, fluorescence, magnetic property, and heating efficiency of SP-NCs offer promising opportunities for biomedical applications.

Summary: In this study, we investigated the effect of Ir substitution into Fe sites on the band gap of LuFeO3 material. LFO and Ir-doped LFO (LuFe1-xIrxO3 or LFIO for short, where x = 0.05 and 0.10) thin films were synthesized using magnetron sputtering techniques. The crystallographic orientation and surface topography of the films were examined using X-ray diffraction (XRD) analysis and atomic force microscopy (AFM), respectively. Photoluminescence (PL) spectroscopy was used to study the recombination of photogenerated electron-hole pairs, while Raman spectroscopy provided information on crystal symmetry and defects in the oxide materials. It was found that the LFO band gap could be changed from 2.35 to 2.72 eV by Ir substitution into Fe sites. In addition, diffuse reflectance spectroscopy (DRS) was employed to analyze various optical properties of the materials.

Summary: LuFe1-xOsxO3 (x = 0, 0.05, and 0.10) compounds were synthesized and their resistivity, impedance, and frequency-dependent loss tangent were investigated at different temperatures. Impedance and resistivity increased with the doping procedure, while activation and loss tangent values decreased. X-ray photoelectron spectroscopy (XPS) revealed the oxidation state of Lu and peaks for lattice oxygen and oxygen vacancy. Scanning electron microscopy (SEM) images showed particle agglomeration and void formation. Single and double oxygen vacancies and ion hopping were responsible for the reported activation energies. The compounds exhibited a low loss factor even at high temperatures.

Summary: Due to its electrical, magnetic, and optical characteristics, LuFeO3 (LFO) has garnered interest from the scientific community. This study prepared powders of LFO, LuFe0.95Co0.05O3, and LuFe0.90Co0.10O3 samples using the solid-state approach. Characterization techniques such as XRD, SEM, and XPS were employed to analyze the samples' crystalline structure, particle size, and oxidation states of Fe and Co. The undoped LFO sample exhibited higher conductivity and dielectric constant compared to the Co-doped LFO samples. Magnetic experiments using VSM showed that Co doping increased the Mr values, which could be attributed to variations in the inclined angles of Fe3+ moments and the growth of magnetocrystalline anisotropy's energy.

The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
