Fluidization of nanopowders: a review [PDF]
Journal of Nanoparticle Research, 2012 Nanoparticles (NPs) are applied in a wide range of processes, and their use continues to increase. Fluidization is one of the best techniques available to disperse and process NPs. NPs cannot be fluidized individually; they fluidize as very porous agglomerates.
