Summary: Copper and dysprosium doped NiFe2O4 magnetic nanomaterials were prepared and investigated for the photodegradation of methylene blue pollutant, electrocatalytic water splitting, and antibacterial activities. The results showed that the doping of copper and dysprosium can increase the saturation magnetization and decrease the optical band gap, leading to enhanced photocatalytic degradation efficiency and excellent electrocatalytic properties. The produced magnetic nanomaterials also exhibited significant antibacterial activity against gram-positive bacteria.

Summary: A series of Ce3+ doped Co-Cd nanoferrites were synthesized and their structural, optical, dielectric and photocatalytic characteristics were investigated. Ce3+ doping led to a decrease in particle size, cell volume, and lattice constant, as well as an increase in band gap energy. The photocatalytic activity of Co-Cd was not significantly affected by Ce3+ doping within a certain range, but further increase in Ce3+ content notably suppressed the photocatalytic activity.

Summary: NiOx, Li:NiOx, and Li,Mg:NiOx powders were produced by sol-gel method, and their structural and optical properties were studied. XPS results confirmed the successful incorporation of Li+ and Mg2+ into NiOx structure, with decreased crystallite size as dopant concentration increased. Addition of Li+ and Mg2+ led to reduced emission intensity and average decay time compared to pristine NiOx.

Summary: This paper reports a solution auto-combustion (AC) process for the rapid synthesis of Fe3O4 nanoparticles derived from the sol-gel (SG) process. By using citric acid (CA) and tartaric acid (TA) as gelling agents in the SG process, citric acid acts as a fuel that combusts the gel and yields highly magnetic crystalline Fe3O4 nanoparticles in one step. In contrast, different concentrations of citric acid and any concentrations of tartaric acid do not induce combustion and only result in amorphous iron oxides. Upon annealing, the CA and TA derived iron oxide samples transform into crystalline alpha-Fe2O3 particles. Photocatalytic studies show that the synthesized Fe3O4 nanoparticles exhibit higher photocatalytic efficiency and stability under simulated solar light irradiation.

Summary: We investigated the properties of 20MnFe(2)O(4)-80SiO(2) nanocomposite prepared using auto-combustion method. Structural and morphological analysis showed the formation of MnFe2O4 nanocrystallite and presence of alpha-Fe2O3 particles. The nanocomposite exhibited semiconductor behavior and non-Debye relaxation in conductivity measurements. VSM measurements revealed deviation from ideal magnetism due to the presence of alpha-Fe2O3 impurities. Mossbauer spectra confirmed the presence of Fe3+ ions and alpha-Fe2O3 components in the nanocomposite.
