Synthesis of magnetic iron oxide nanoparticles at the interface of the polyethylene glycol–ammonium sulfate–water extraction system

The synthesis of iron oxide nano- and microparticles in the PEG 3000–ammonium sulfate–water extraction system has been accomplished for the first time. Upon the addition of a solution of ammonia, iron oxide particles with sizes from 200 nm to 10 μm are produced at the interface. The phase compositio... View More
