-FeOOH thin films were produced by Chemical Bath Deposition (CBD) method at pH: 5 onto amorphous glass substrates. Structural properties of -FeOOH thin film were analyzed with X-ray diffraction (XRD). Chemical analysis and surface image of thin film were investigated with EDX, SEM, respectively. Optical properties were investigated via UV-VIS spectrophotometer. -FeOOH (lepidocrocite) crystal is orthorhombic structure and the XRD peak corresponding to the -FeOOH is enhanced to (1 1 1) plane. The allowed direct and allowed indirect optical band gaps (Eg), optical transmission (T%), reflectivity (R%), absorption, refraction index (n), extinction coefficient (k), dielectric constant (ɛ) of the thin film were found to be 2.00 and 1.63 eV, 36.39 %, 24.86 %, 0.43, 2.98, 0.03 and 1.76, respectively..

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.
