We report the advantage of exchange coupling between a magnetically soft (MnFe2O4) and hard (Co0.7Zn0.3Fe2O4 Co0.5Zn0.5Fe2O4) magnetic phase to increase specific absorption rate (SAR) in inductive heating. All samples were synthesized by hydrothermal method. While saturation magnetization (Ms) two composite nanoparticles is approximately 1.1 times higher Ms single-component, SAR more 2 than tho...

Divalent ferrite nano-crystalline materials subjected to shock wave recovery analysis bringing about prolific outcomes have received widespread attention among the scientists due their outstanding contribution that has fueled enrichment of science involving high-pressure ferrites which act as focal-point current research theme. On those lines, we intend provide Raman spectroscopic and electroch...

The hybrid nanoparticles Ag-MnFe2O4 was successfully fabricated by the seed-growth method and thermal decomposition method. shape size of these were evaluated Transmission electron microscopes (TEM) images showing that are quite uniform have a diameter about 20 nm. UV-Vis spectrum shows in wavelength region from 300 to 800 nm, ferrite manganese nanoparticle does not appear an absorption peak, w...

Arsenic in water is currently a global concern due to the long-term exposure that could affect human health. In this study, magnetic nanoparticles (MNPs), CoFe2O4, and MnFe2O4 were successfully synthesized applied remove arsenic (As) from water. The MNPs characterized using different techniques, such as scanning electron microscope (SEM), Brunauer–Emmet–Teller (BET), photoelectron spectroscopy ...

The temperature dependence of the effective magnetic anisotropy constant, K(T), of MnFe2O4 nanoparticles is obtained based on superconducting quantum interference device magnetometry measurements. The variation of the blocking temperature, TB, as a function of particle radius, r, is first determined by associating the particle size distribution and the anisotropy energy barrier distribution ded...

In this work, lamellar MnFe2O4 was successfully planted on a wood surface through the association of hydrogen bonds via the one-pot hydrothermal method. Simultaneously, the fluoroalkylsilane (FAS-17) on the surface of the MnFe2O4 layer formed long-chain or network macromolecules through a poly-condensation process and provided a lower surface energy on the wood surface. The MnFe2O4/wood composi...

Abstract Manganese ferrite (MnFe 2 O 4 ) nanoparticles were synthesized via a hydrothermal method and combined with exfoliated MoS nanosheets, the nanocomposite was studied as supercapacitor. X-ray diffractometry Raman spectroscopy confirmed crystalline structures structural characteristics of nanocomposite. Transmission electron microscopy images showed uniform size distribution MnFe (~ 13 nm)...

This work aimed to synthesize MnFe2O4 nanoparticles using the coprecipitation method. Manganese chloride dihydrate (MnCl2.4H2O) and iron sand from South Cianjur, Indonesia, were used as a precursor for nanoparticle synthesis. The elements compounds tested X-Ray Fluorescence (XRF). was characterized Diffraction (XRD), Scanning Electron Microscope-Energy Dispersive (SEM-EDX), Vector Network Analy...
