From: Electrokinetic Properties of TiO2 Nanotubular Surfaces
Calculated magnitude of the electric field strength as a function of the distance from the surface in normal direction to the surface (d) in the case of NT wall surface far from the top edges (full line), and at the highly curved top edge region (dashed line). The parameters used in the simulations are σ = −0.2 As/m2, NaCl concentration = 100 mM, α − = 12 and α + = 8
