Sol-gel thin films of hydroxyapatite (HA) and titania (TiO(2)) have received a great deal of attention in the area of bioactive surface modification of titanium (Ti) implants. Sol-gel coatings were developed on Ti substrates of pure HA and TiO(2) and two composite forms, HA+10% TiO(2) and HA+20% TiO(2), and the biological properties of the coatings were evaluated. All the coating layers exhibit...

For effectively fabricating nanocrystalline ZnO thin films by the sol-gel method, the relationships between the temperature of the heat treatment and the quality of the ZnO thin films was observed. The decomposition of the sol was analyzed by TG-DTA. The orientation of the c-axis of the ZnO thin film was identified by XRD. The morphology was observed and estimated by SEM. The experimental resul...

the sno2 films deposited from inorganic precursors via sol–gel dip coating method have been found to be highly sensitive to methanol and ethanol vapor. three dimensional nano-structure materials have attracted the attention of many researches because the possibility to apply them for near future devices in sensors, catalysis and energy related. the sensitivity and selectivity of sno2 (110) nano...

Thin ZnO films are deposited on glass substrates via sol–gel method and dip-coating. The films are prepared from zinc acetate dehydrate as a starting reagent. After that the as-prepared ZnO sol is aged for different periods (0, 1, 3, 5, 10, 15 and 30 days). Nanocrystalline thin films are deposited from various sols. The effect ZnO sols aging time on the structural and photocatalytic properties ...
