Illustration of surface-charged CNTs used in the simulations in (a) top view, and (b) side view. In the figure, a (16,16) CNT is displayed and a ring including three charges is located in the middle of the tube. Water molecules and ions are not shown here. The particles outside the tube represent the negative surface charges.
