Magnetic nanoparticle (MNP)-based magnetic resonance imaging (MRI) contrast agents (CAs) have been the subject of extensive research over recent decades. The particle size of MNPs varies widely and is known to influence their physicochemical and pharmacokinetic properties. There are two commonly used methods for synthesizing MNPs, organometallic and aqueous solution coprecipitation. The former ...

Magnetic fluids based on single-domain magnetic spinel ferrite nanoparticles dispersed in various liquid media are of particular practical and scientific interest. This paper presents a muon spectroscopy study ferrofluid CoFe2O4 molecules water (H2O) with nanoparticle concentration 3%. In this study, it was determined that the structure magnitude magnetization depend viscosity itself. It shown ...

Magnetic and microwave absorption properties of CoxFe(3-x)O4 semi-hard materials (x = 0.75, 1.0, 1.5) synthesized have been carried out using the chemical method sol-gel. The mixture iron nitrate Fe2(NO3)3 cobalt Co(NO3)2 dissolved in ethylene glycol, then was heated while stirring at 60 °C for 1 hour to form a gel. After that dried temperature 120°C 5 hours. A fine powder obtained through grin...
