Figure 1From: Formation of self-organized Zircaloy-4 oxide nanotubes in organic viscous electrolyte via anodizationFESEM images of the as-anodized Zr-4 oxide nanotubes. The nanotubes were prepared in ethylene glycol (EG) electrolyte containing a small amount of NH4F and DI water showing the top (a) and cross-sectional (b)-(c) surface morphology.
