Electrokinetic properties of aqueous ferrofluids.
France / Франция
The simultaneous acoustophoretic, conductimetric and potentiometric measurements of a charge-stabilized aqueous ferrofluid and their consistent interpretation have proven to be an efficient method to understand acutely the charging processes of the magnetic nanoparticles. Both the protonation state of the surface and the effective charge, ruling the colloidal stability, have been investigated.
