The magnetic contribution of the solvent on the RT ac magnetic susceptibility behaviour of Fe3O4 magnetic nanoparticles in solution at different concentrations, is presented and discussed. The room temperature complex susceptibility of the solvent water was studied as a function of several parameters, namely different ac fields, superimposed dc...

Magnetite (Fe3O4 ) and silica-coated magnetite (Fe3O4@SiO2) nanoparticles (NPs) were synthesized and characterized by scanning and transmission electron microscopy and by a.c. susceptibility measurements as a function of the frequency both at room temperature and 80 K. A new mathematical approach based on the explicit coexistence (at room...

Nickel nanoparticles (NPs, particle radius <8 nm) were prepared via reduction method in aqueous solution and were structurally and morphologically characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). A DC-SQUID magnetometer was also used to determine the particle size. As a reference, a high loading (125% Ni...

This paper describes the synthesis, functionalization, and multitechnique analysis of magnetic nanoparticles. The synthetic method involves the covering of a magnetite nucleus by a silica layer and the further functionalization with different fluorophores via a cross-linker molecule. All synthetic intermediates were analyzed by fluorescence...

Results obtained in the synthesis, characterization and application as catalyst of cobalt nanoparticles are reported. Cobalt nanoparticles were prepared via reduction method in aqueous solution. Structural characterization was carried out using X-ray diffraction (XRD), morphological studies were performed with a scanning electron microscope...
