Well-ordered titania nanotube arrays (TNAs) were successfully synthesized by three-step anodization in the ethylene glycol-based electrolytes containing lactic acid. The tube length of TNAs was found to be almost linearly dependent on the anodization temperature when the potential difference was kept constant at 60 V. However, their pore diameter reached a maximum at 40°C and then decreased with increasing temperature. The addition of lactic acid to the electrolytes greatly improved the morphology of TNAs, producing well-ordered nanotubes with ripples on the walls. Moreover, the XRD results showed that the crystal structure of TNAs was closely related to the annealing temperature. The growth mechanism of TNAs in the presence of lactic acid was also explained..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
