Sonochemical synthesis of Dy3+ substituted Mn0.5Zn0.5Fe2−xO4 nanoparticles: Structural, magnetic and optical characterizations

Structure and magnetic properties of coprecipitated nickel-zinc ferrite-doped rare earth elements of Sc, Dy, and Gd

“…As shown in Table 3, the magnetic moment of the doped sample is higher than that of the undoped sample, which can be used to explain the higher M S value of the substituted sample and the enhanced super exchange interaction of the doped samples [40]. It can be seen from Fig.…”

Sonochemical catalysis as a unique strategy for the fabrication of nano-/micro-structured inorganics

“…Spinel ferrites are promising magnetic materials that are widely used in various fields, so lately, the sonochemical syntheses of novel spinel ferrite nanostructures have become an active research area. [74][75][76][77][78] For example, Almessiere, Slimani and coworkers produced a series of high-purity spinel ferrite compositions via the ultrasonic irradiation, such as [79][80][81][82][83][84][85][86][87][88][89][90][91][92][93] They examined the structural properties, morphological properties, and physical properties (e.g., magnetic traits, optical traits, and electrical traits) of products, and even evaluated their biological characterization for potential anti-cancer and anti-bacterial capabilities. Additionally, they also utilized ultrasonic-assisted approaches to prepare many ferromagnetic 19 (x = 0.00~0.05) hexaferrites, and so on.…”

A power-triggered preparation strategy of nano-structured inorganics: sonosynthesis

“…[5][6][7][8][9] By comparison, low-frequency ultrasound is widely used in research and industry to efficiently clean the debris from surfaces, or to purify the water by degrading contaminants, or to initiate the reduction, oxidation and hydrolysis reactions, or to accelerate crystallization and polymerizations. [10][11] For example, the sonolysis or ultrasonic catalysis, as one of advanced oxidation processes (AOP), has been exploited for the degradation of toxic organics in order to protect the aqueous environment, where ultrasound irradiation combining with other AOPs and/or oxidizing agents can enhance the reaction rate, decrease the processing conditions, and reduce the overall energy consumption. [12][13] Figure 1 lists the general applications of low-frequency ultrasound in chemistry, material, engineering and manufacturing fields, and many processes of them refer to the chemical effects from ultrasound.…”
