Fe3O4 nanoparticles were synthesized in the presence of pepper extract as a capping agent via a hydrothermal method. Then palladium nanoparticles and Fe3O4-Pd nanocomposites were synthesized with the aid of pepper extract as a reducing agent. Vibrating Sample magnetometer illustrated that Fe3O4 nanoparticles have super paramagnetic behaviour. The photo catalytic behaviour of Fe3O4-Pd nanocompos...

As hybrid nanostructures have become more important in many fields of chemistry, Ag nanoparticles (NPs) are being increasingly immobilized onto Fe3O4 microspheres in situ. Structural characterization reveals that the Ag NPs are uniformly immobilized in the Fe3O4 microsphere-based supports. Moreover, Ag NPs are more stable in the hybrid structure than in the naked state and show high catalytic a...

The aim of this study is to obtain polysaccharide (Glucose, Fructose and Sucrose) stabilized superparamagnetic iron oxide nanoparticles (SPIONs) by Co-Precipitation method. As prepared iron oxide nanoparticles have been characterized by X-ray Diffraction (XRD), Fourier Transform infrared (FTIR) spectroscopy, UV–Vis NIR spectroscopy, High Resolution Transmission Electron Microscope (HRTEM) and V...

in the present study, fe3o4 super paramagnetic nanoparticles were synthesized via co-precipitation of fe3+ and fe2+ chloride salts in the presence of ammonia solution. the product was characterized by fourier transform infrared spectroscopy (ft-ir), transmission electron microscopy (tem), and zeta–potential particle size distributing methods. the synthetic procedure of nano iron oxides were opt...

In this paper, Fe3O4-chitosan nanoparticles were prepared by the immobilization of chitosan on the surface of Fe3O4 nanoparticles. Then, the 5-substituted hydantoins were synthesized from the condensation of aldehyde derivatives, ammonium carbonate and zinc cyanide as a well-known cyanating agent by the magnetic Fe3O4-chitosan nanoparticles under neat conditions. Fe3O4-Chitosan nanocatalyst as ...

The unique properties and applications of iron oxide and Au nanoparticles have motivated researchers to synthesize and optimize a combined nanocomposite containing both. By using various polymers such as chitosan, some of the problems of classic core-shell structures (such as reduced saturation magnetization and thick coating) have been overcome. In the present study, chitosan and one of its we...

Multifunctional silica nano-vehicles (SiO2@indol-IL) and magnetic nanoparticles (Fe3O4@indol-IL) were constructed through the Schiff bases condensation of indole-3-carboxaldehyde and 4-acetyl-N-allyl pyridinium chloride (ILs) with the amine groups of silica and magnetic nanoparticles. SiO2@indol-IL can inhibit the proliferation of HepG-2 cells in 48 h. Fe3O4@indol-IL can mimic the function of c...

Iron oxide exhibits fascinating physical properties especially in the nanometer range, not only from the standpoint of basic science, but also for a variety of engineering, particularly biomedical applications. For instance, Fe3O4 behaves as superparamagnetic as the particle size is reduced to a few nanometers in the single-domain region depending on the type of the material. The superparamagne...
