This study described the synthesis of TiO2 nanoparticles in silica microspheres (nano TiO2 SiO2 microspheresmicrospheres) via precipitation in situ and reverse emulsion approach FT IR spectra indicated the presence of TiOSi chemical bonds in the se nanocomposite microspheres. TEM images of the nanocomposites revealed that TiO2 nanoparticles having parti cle sizes laying in the range of 10 50 nm were encapsulated in the network of silica (mosaic structure). XRD confirmed heat treatment at 650 oC, the formation of anatase phases in the nanocomposites. UV vis revealed that ultraviolet (260 350 nm) can be abs orbed by the nanocomposites with potential applications in photocatalysis sciences..

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.
