PVP capped Titania (TiO2) nanostrips were prepared by co-precipitation method using titanium (IV) isopropoxide, with ethylene glycol as a solvent and H2O as a hydrolyzing agent. The synthesized samples were subjected to powder XRD analysis, which confirms anatase phase formation of TiO2. Strip-like morphology was observed using high resolution scanning electron microscopy (HRSEM). Crystallinity of the synthesized sample was analysed by high resolution transmission electron microscopy (HRTEM). Band gap estimated by UV-Reflectance spectroscopy with the value of 3.54 eV and the surface area of 91.87 m2/g of the sample were calculated by BET analysis and its functional groups were analyzed through FTIR spectroscopy. The photocatalytic activity of synthesised titania nanoparticles was studied on the photodegradation of rhodamine in water under ultraviolet light irradiation.

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.
