Effect of reaction condition on microstructure and properties of (NiCuZn)Fe2O4 nanoparticles synthesized via co-precipitation with ultrasonic irradiation

Abstract

Highlights Crystallites sizes of nanoparticles synthesized via ultrasound irradiation were less than 40nm. Ms and Hc of nanoparticles obtained at 25℃ were higher than at 50℃ under the same power. The samples exhibited the highest Ms at 25℃ and the lowest Hc at 50℃ both for 60W. The ultrasonic irradiation had a positive effect on improving the ferrite magnetic properties.

“…previous research;68,69 a single phase of Ni 0.4 Cu 0.2 Zn 0.4 Fe 2 O 4 with cubic spinel structure [69][70][71]. On the other hand, no extra lines corresponding to any other phases can be detected that indicates the resulting spinel ferrite is relatively pure.…”

Enhancement of Magnetic and Dielectric Properties of Ni0.25Cu0.25Zn0.50Fe2O4 Magnetic Nanoparticles through Non-Thermal Microwave Plasma Treatment for High-Frequency and Energy Storage Applications

“…Mn 2+ addition cause an increase in permeability with a drop in resonance frequency. Peng et al [ 13 ] synthesized NiCuZn ferrite via a co-precipitation method with ultrasonic assistance and analyzed the influence of temperature and ultrasonic radiation on magnetic characteristics and microstructures of nanoferrites. The best magnetic properties were obtained at room temperature (RT) with assistance of 60W ultrasonic power.…”

Anti-Bacterial Iron Oxide Magnetic Nanoparticles based on Orange Peel Extract

“…Antibacterial PTT uses light irradiation, typically in the near-infrared (NIR, 700-1350 nm, optical window) (29), to raise the temperature ~ 50 °C of PTAs (30,31), which host bacteria cell membranes or internalize by several mechanisms like passive diffusion, receptor-mediated endocytosis, among others (1,32,33), causing irreversible damage in the cell membrane and protein disruption which leads to bacterial death (16). When using MNPs-Fe as PATs, a characteristic effect is achieved known as Localized Surface Plasmonic Resonance (LSPR).…”

“…The phagocytes use their plasma membrane to engulf NPs (phagocytosis) or, in turn, are inhibited by forming a crown of non-specific proteins, producing unpredictable pharmacokinetics (35). Thus, their size, morphology, and surface chemistry play an essential role in the interaction with target cells; e.g., the kidneys remove size NPs < 10 nm, and the liver removes size NPs > 10 nm, which can also be phagocytized (33,34). To improve the availability of NPs in the biological environment, they typically are functionalized with polymeric molecules such as polyethylene glycol (PEG), which produces a protein repulsion effect; or molecules of interest that allow increasing selectivity toward target cells (26).…”
