From: Electrokinetic Properties of TiO2 Nanotubular Surfaces
Calculated distribution of electric potential around the wall of TiO2 nanotube (in Volts). The white surface shows the cross section of the nanotube wall. The parameters used in the simulations are σ = −0.2 As/m2, NaCl concentration = 100 mM, α − = 12 and α + = 8
