The testing results showed that the magnetic fluid had excellent stability, and had susceptibility of 4.46脳10 8 and saturated magnetization of 6.56 emu/g. In addition, the mean size d (0.99) of magnetic Fe 3O 4 nanoparticles in the fluid was 36.19 nm....
Free nanoparticles of iron (Fe) and their colloids with high saturation magnetization are in demand for medical and microfluidic applications. However, the oxide layer that forms during processing has made such synthesis a formidable challenge. Lowering the synthesis temperature decreases rate of oxidatio...
The magnetic behavior of individual magnetite (Fe3O4) nanoparticles (MNPs) has arisen considerable attention in environmental application. However, magnetic properties and stability weaken due to their high susceptibility to chemical activity (oxidation). Efforts have increasingly been made to encapsulate ...
Magnetic nanoparticles exhibit many interesting properties that can be exploited in a variety of applications such as catalysis and in biomedicine. This review discusses the properties, applications, and syntheses of three magnetic iron oxides-hematite, magnetite, and maghemite-and outlines methods of pre...
and have concluded that it is not viable to add expensive metals to photo-catalytic systems in order to enhance the removal of EDCs found in low concentrations in real wastewaters. In this respect, the application of heterogeneous catalysts consisting in surface engineered magnetic nanoparticles (MNPs...

Synthesis of magnetite (Fe 3O 4) nanoparticles under oxidizing environment by precipitation from aqueous media is not straightforward because Fe 2+ gets oxidized to Fe 3+ and thus the ratio of Fe 3+:Fe 2+=2:1 is not maintained during the precipitation. A molar ratio of Fe 3+:Fe 2+ ...
The nanoparticles used were removed from the sample by magnetic separation. Unless specified elsewhere the reaction conditions were carried out as mentioned above. The specific energy consumption (SEC) was calculated from the following expression (Eq. (1)):(1)SEC=L*NP*t/mL = number of lamps,...
The analysis methods of XRPD, TEM, TGA, and VSM are used to characterize the magnetic nanoparticles. Through the characterization of the precipitated nanoparticles, the effects of the reacting component proportions and preparation techniques on the Curie temperature, the magnetization, and the size ...
