Effect of Bi₂O₃–CuO Flux on the Microstructure, Soft Magnetic Properties, and Gyromagnetic Properties of NiCuZn Ferrites for LTCC Devices

Micromachines
In this work, the electromagnetic properties of Ni0.22Cu0.31Zn0.47Fe2O4 (NiCuZn) ferrites doped with 0.3 wt% Bi2O3 + xCuO flux (x = 0.2, 0.4, 0.6, and 0.8 wt%) were studied. Doping resulted in a reduction in the sintering temperature to 900 °C. The doped

Phosphate Removal by ZIF‐8 and Magnetic Fe3O4/ZIF‐8: A Comparative Study of Capacity, Kinetics, and Regeneration

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT This study presents a comparative evaluation of phosphate adsorption on pristine ZIF‐8 and Fe3O4‐doped ZIF‐8 (Fe3O4/ZIF‐8), a hybrid adsorbent combining high surface area with magnetic separability. Structural integrity and composition were confirmed using SEM, XRD, FTIR, and XPS.

Magnetocapacidad en nanopartículas de Fe₃O₄ y NiFe₂O₄

Boletín de la Sociedad Española de Cerámica y Vidrio, 2010
We have synthesized NiFe2O4 (φ∼ 6 nm) and Fe3O4 (φ∼ 30 nm) magnetic nanoparticles by solvothermal synthesis; furthermore the Fe3O4 nanoparticles have been coated with a SiO2 shell of approximately 5 nm of thickness by the Stöber method.
