Highly ordered TiO2 nanotubes array have been prepared through anodization process in fluoride based electrolyte. ZnO nanosheets have been grown on the as-anodized TiO2 nanotubes through rapid electrodeposition process in ethanolic Zn(NO3)2 electrolyte and the identical procedures have been repeated on Zn foil for comparison. No extreme temperature and only low applied potential were required in the process of fabricating ZnO nanosheets. The growth manner of the ZnO nanosheets whereby the nanosheets favoured to be in near spherical cluster instead of individual sheets has been ascribed to the minimum surface energy. The dimensions of the cluster and individual nanosheet have been analyzed through a large population to evaluate the average sizes. X-ray diffraction and Raman measurement results supported the suggested chemical reactions for the formation of nanosheets and proved that the nanosheets are comprised of ZnO. It has been discovered that the ZnO nanosheets grown on both TiO2 nanotubes and Zn foil demonstrated similar physical properties, with additional advantages on the use of TiO2 nanotubes template..

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.
