A Novel Methodology for Economical Scale-Up of TiO₂ Nanotubes Fabricated on Ti and Ti Alloys

Figure 6

Statistical plots of the nanotube dimensions correspond to their respective anodising potentials; (a) the pore diameter (lower bar, labelled PD) and the interpore distance (upper bar, labelled ITD) of the anodised specimen using Version A (first bar with solid black fill) and one specimen from each of the four batches using Version B (bars with patterned fill), chosen from different positions in the 10-specimen holder, i.e., top corner, middle, bottom corner, and random position, as indicated in Figure 3. (a) , error bars represent standard deviation; (b) the nanotube length of the anodised specimens, measured using the same specimen as (a) (, error bars represent standard deviation).
