in this paper, a modified sol-gel method using peroxotitanic acid sol (pta) was applied for the preparation of tio2 nanostructured thin films on glass plates. the peroxotitanic acid sol was synthesized using titanium isopropoxide, isopropylalchol, h2o and hydrogen peroxide. tio2 films were then calcined at 500oc and characterized by x-ray diffraction (xrd) and scanning electron microscopy (sem)...

Titanium (Ti) is one of the most promising biomaterial for biomedical devices due to its high corrosion resistance and specific combination of strength and biocompatibility. Titanium dioxide (TiO2) nanostructures are obtained by electrochemical anodization of Ti foils under self-organization condition; anodization parameters such as anodization time, voltage, temperature and most important elec...

In this work, we demonstrate that chronoabsorptometry and more specifically cyclic voltabsorptometry are particularly well suited techniques for acquiring a comprehensive understanding of the dynamics of electron transfer/charge transport within a transparent mesoporous semiconductive metal oxide film loaded with a redox-active dye. This is illustrated with the quantitative analysis of the spec...

Titanium dioxide is one kind of important materials, which has been extensively investigated because of its unique electronic and optical properties. A large number of efforts have been made to synthesize TiO2 materials with different methods. In this review paper, we summarize the synthesis pathways, morphology, as well as crystallization of the nanostructured TiO2. In ad...
