dc.description.abstractUltrasound was throughout employed to enhance the co-precipitation process for the synthesis of magnetite nanoparticles (Fe3O4) and the St€ ober approach for the preparation of magnetite-silica nanocomposites (Fe3O4/SiO2). The synthesised magnetite nanoparticles exhibited single-domain nano-crystallites with a uniform spherical morphology, a narrow size distribution (ca. 10 nm), and negligible coercive field (~5 Oe). The prepared magnetite-silica nanocomposites possessed a mono core-shell structure with spherical morphology, biologically coherent size (ca. 100 nm), and discrete mono-domain behaviour. The crystalline structure-magnetic behaviour relationships of the nanomaterials were investigated to imply the presence of a surface protection at nanoscale. The speculation indicated that shock waves took place as the surface-protective role rather than the original mechanical interaction of ultrasound with a larger scope of impact.vi
