A mesoscopic scale approach and the Monte Carlo method have been employed to study exchange bias behaviour of MnFe 2 O 4 @γ-Fe 3 CoFe nanoparticles size ∼3 nm in dense diluted assemblies at low temperatures.
We investigated the inductive detection signal of Mn-ferrite nanoparticles and compared it to magnetite. Our results suggest that Mn-ferrites are promising nanolabels for detecting quantifying analytes in magnetic lateral flow immunoassays.
The electro-activity of MFe<sub>2</sub>O<sub>4</sub>@γ-Fe<sub>2</sub>O<sub>3</sub>(M = Mn, Co, Cu and Zn) nanoparticles occurs at the surface layer reflects environment.
Magnetic nanopowders were developed by functionalization of bimagnetic core@shell nanoparticles with cysteine (CoFe2O4@ɣ-Fe2O3@Cys), which present a core high saturation magnetization (CoFe2O4) combined shell long-term chemical stability (ɣ-Fe2O3) and sorptive L-cysteine layer. Samples two different mean sizes elaborated characterized XRD, TEM, FTIR, SER, zetametry SQUID magnetometry. The adsorption Pb(II) the magnetic was investigated as function pH, time, pollutant concentration. Langmuir...
