VO2 films were prepared on silicate glass, mica and quartz substrates respectively with the sol-gel method and subsequent spin coating technique. It was found that the substrates could significantly affect the film’s structure and property. The film on quartz substrate had the highest purity and the best crystallinity, and that on glass substrate followed. For all prepared films, the resistivity was temperature dependent, and the heating and cooling curves formed a hysteresis loop. The resistivity of quartz film at the room temperature was about 7 times that of mica film, and about 14 times that of glass film. During the heating process, the phase transition points of the films on silicate glass, mica and quartz substrates were 67℃, 68℃ and 64℃, and their resistivity mutations were about 2.1, 3.0 and 2.5 orders of the magnitude 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.
