The role of the electrode geometry on the dielectrophoretic assembly of multi-walled carbon nanotube bundles from aqueous solution

This paper investigates the influences of the electrode geometry in terms of shape, configuration, dimensions, overlapping, and extensions on the dielectrophoretic (DEP) assembly of multi-walled carbon nanotube (MWCNT) bundles. A computational model was employed to predict the motion, trajectory, an...
