High-aspect-ratio TiO2 nanotube (NT) arrays were successfully fabricated by anodization of Ti foils in an ethylene glycol electrolyte containing 0.25% NH4F and 1V% H2O. The structure and morphology of the NT arrays were characterized by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM). The arrays were found to several micrometers in length, with tube diameters of 70100 nm. The samples calcined at 400500C showed only anatase phase. The photovoltaic performance of the TiO2 NT and nanoparticle (NP) films used in dye-sensitized solar cells (DSSCs) were investigated by IV characteristics curve. The results indicated that all the NT-based DSSCs have better photovoltaic performance than the NP-based counterparts owing to higher charge collection efficiencies and higher surface area..

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.
