Stable colloidal dispersions of magnetic nanoparticles in aqueous media and polymer melts
The work presented as part of this thesis describes a process to obtain two types of conventionally used magnetic nanoparticles, magnetite and cobalt ferrite, with a narrow size distribution that can be suspended in aqueous ...
Probing nanoscale viscosity in polymer melts using magnetic nanoparticles.
Oleic acid coated cobalt ferrite nanoparticles (CoFe2O4-OA), which relax through the Brownian mechanism, were dispersed in Polystyrene (PS) and Polybutadiene (PBD) of various molecular weights (MW). These suspensions were ...
