Agglomeration, colloidal stability, and magnetic ...

Abstract Magnetic nanoparticles (MNPs) which ex-hibit magnetic and catalytic bifunctionalities have been widely accepted as one of the most promising nanoagents used in water purification processes. How-ever, due to the magnetic dipole-dipole interaction, MNPs can easily lose their colloidal stability and tend to agglomerate.

Fluidization and mixing of nanoparticle agglomerates ...

The collisions between the magnetic particles and the nanoparticle agglomerates are expected to provide enough kinetic energy to break-up the agglomerates, and thus cause the nanoparticles to mix at the sub-agglomerate (i.e., nano) scale.
