Abstract:
1. A method for mixing or blending nanopowders or nanoagglomerates at nanoscale, comprising: a. introducing at least a first nanopowder or nanoagglomerate and a second nanopowder or nanoagglomerate into a fluidization chamber; b. delivering a fluidizing medium to the fluidization chamber, the fluidizing medium being directed in an upward direction relative to the fluidization chamber; c. delivering a substantially downwardly directed gas flow to the fluidization chamber, the gas flow being introduced to the fluidization chamber by at least one micro-jet nozzle; wherein the fluidizing medium and the substantially downwardly directed gas flow are effective to substantially uniformly mix the first and the second nanopowders or nanoagglomerates at the nanoscale; and wherein the micro-jet nozzle is configured to prevent or mitigate a buildup of electrostatic charges.
