Abstract:
1. A method for separating particles, comprising: dispersing a plurality of particles in a fluid to form an aerosol, a portion of the particles having a first morphology and a portion of the particles having a second morphology; charging at least a portion of the particles to produce a charged aerosol, the charged aerosol comprising particles having a first electrical mobility-to-charge ratio, comprising particles of the first morphology and particles of the second morphology, and particles having a second electrical mobility-to-charge ratio; separating the particles of the first electrical mobility-to-charge ratio from the particles of the second electrical mobility-to-charge ratio, the separated particles of the first electrical mobility-to-charge ratio being selected particles; charging the selected particles to produce particles of the first morphology having a first electrical mobility and particles of the second morphology having a second electrical mobility; and separating particles of the first electrical mobility from particles of the second electrical mobility.
