The study was based on understanding the relationship between titanium (Ti) doping amount and magnetic heating performance of magnetite (Fe3O4). Superparamagnetic nanosized Ti-doped ((Fe1?x,Tix)3O4; x = 0.02, 0.03 0.05) particles were synthesized by sol-gel technique. In addition to (Fe1?x,Tix)3O4 nanoparticles, SiO2 coated nanoparticles produced as core-shell structures understand effects sili...

This study successfully synthesized magnetically-manipulatable and reusable SERS active buoyant substrates, i.e. [email protected]2@Fe3O4 composite hollow spheres. The composites comprised mesoscopic spheres with a Fe3O4 inner shell of 15–30 nm in thickness strong ferromagnetism, which were using spray pyrolysis the subsequent reduction, SiO2 outer to maintain stability Fe3O4, as well Ag nanopa...

Objectives: The study of core-shell magnetic nanoparticles has a wide range of applications because of the unique combination of the nanoscale magnetic core and the functional shell. Characterization and application of one important class of core-shell magnetic nanoparticles (MNPs), i.e., iron oxide core (Fe3O4/γ-Fe2O3) with a silica shell and outer of gold (Fe3O4-SiO2@Gold (FSG)) in Boron Neut...
