Alternating Field Electronanofluidization
(American Institute of Physics, 2009)
The use of fluidized beds to remove submicron particles from gases has been investigated since 1949. High efficiency removal was achieved in the 1970’s by imposing an electric field on a fluidized bed of semi-insulating ...
