Marcoscopic And Microscopic Motion Of Iron Oxide Magnetic Nanoparticles Stabilized Pickering Emulsion, Magnetophoresis At Low Field Gradient

A magnetic responsive of magnetic Pickering emulsion (MPE) was synergistically stabilized by the iron oxide nanoparticles (IONPs) coated by poly(sodium 4-styrenesulfonate) (PSS) and cetrimonium bromide (CTAB) as well as the adjacent CTAB molecules. In this project, MPE, IONPs, IONPs-PSS and IONP-PSS...
