Zhang, Materials Science and Technology (2002), 18(3), 345-348. The synthesis of nanostructured TiO2 and nanostructured CeO2-coated TiO2 has been investigated. On the basis of the synthesis of nano-TiO2, nano-CeO2-coated TiO2 was prepd. by use of sol-gel technol. Preparation and properties of ZnO-TiO2 and WO3-TiO2 composite film photocatalyst. Cheng, Gaodeng Xuexiao Huaxue Xuebao (2001), 22(10, Suppl.), 165-167. ZnO-TiO2 and WO3-TiO2 composite film photocatalysts were prepd. on porous titanium plates by sol-gel method. Their morphol. and structure were characterized by XRD and DTA method. Synthesis and Characterization of Titania Nanostructures on Glass by Al Anodization and Sol-Gel Process. Chu, Chemistry of Materials (2002), 14(1), 266-272. Titania nanostructures with larger surface areas are fabricated on a glass substrate by anodization of sputtered aluminum and the sol-gel process, and the structural characteristics of the nanostructures are investigated. Preparation and tribological properties of sol-gel TiO2-ZrO2 composite thin films. Chen, Science in China, Series A: Mathematics, Physics, Astronomy (2001), 44(Suppl.), 381-386. High oriented TiO2-ZrO2 composite thin films on Si (100) and glass sheet were successfully prepd. by sol-gel process followed by dip-coating the ethanol soln. of zirconium oxychloride and titanium tetrachloride. The sol-gel process, microstructure, morphol. and tribol. properties of TiO2-ZrO2 films were investigated using TGA, DSC, XPS, XRD, AFM and dynamic-static tribo-meter. Formation of TiO2-SiO2 composite thin films and their crystallization behaviors. Otsuki, Key Engineering Materials (2002), 206-213(Pt. 1, Euro Ceramics VII), 539-542. TiO2 thin films were fabricated by a precursor soln. prepd. by mol. precursor method. The dependency of ARPT (anatase-rutile phase transformation) was investigated on the formation temp., the film thickness on an amorphous quartz substrate, and the effects of SiO2 addn. to the TiO2 precursor. Yellow-to-violet upconversion in neodymium oxide nanocrystal/titania/ormosil composite sol-gel thin films derived at low temperature. Que, Journal of Applied Physics (2001), 90(9), 4865-4867. Nd (III) oxide nanocrystals synthesized by the inverse microemulsion technique were dispersed in sol-gel TiO2/organically modified silane (ormosil) composite thin films for photonic applications. X-ray diffraction anal. and TEM observation show that the Nd oxide nanoparticles have a nanocryst. structure and that the size of the nanoparticles is at 5-60 nm Optical properties and charge transport in nanocrystalline TiO2-In2O3 composite films. Poznyak, Thin Solid Films (2002), 405(1-2), 35-41. This work involves a comparative study of nanocryst. titanium and indium oxides as well as TiO2-In2O3 composites prepd. by a sol-gel method from concd. hydrous titanium dioxide and indium hydroxide sols. Highly transparent uniform films were fabricated from the sols by a spin-coating technique. TiO2-In2O3 nanocomposites possess pronounced extreme dependencies of both the apparent bandgap and the refractive index on the film compn. Preparations and characterizations of nanostructured TiO2 and TiO2-Si(Ti)O2 composite systems. Viswanath, Journal of Physics and Chemistry of Solids (2001), 62(11), 1991-1998. Nanocryst. TiO2 and TiO2-SiO2 composites have been prepd. by sol-gel route. The samples are consolidated and sintered to get nanostructured TiO2 and nanostructured TiO2-SiO2 composites. In the TiO2-SiO2 system, the TiO2 nanograins are dispersed in the Si(Ti)O2 matrix. Preparation and characterizations of TiO2/organically modified silane composite materials produced by the sol-gel method. Que, Wenxiu, Journal of Sol-Gel Science and Technology (2001), 20(2), 187-195. TiO2/organically modified silane (ORMOSIL) composite materials produced by the sol-gel method were studied for optical waveguide applications. High optical quality waveguiding films on different substrates, including Si, Ga arsenide, SiO2/Si substrates, and microscope glass slides, were prepd. from high Ti content (0.2 M) y-glycidoxypropyltrimethoxysilane at low temp. http://techreports.larc.nasa.gov/ltrs/PDF/1997/cr/NASA-97-cr201733.pdf http://msewww.engin.umich.edu/courses/MSE440/files_secure/Lecture%206%20Powders-sol.pdf http://my.netian.com/~gyetai/tio2.htm http://www.risoe.dk/afm/symp22/pdf/risoms22_283-288.pdf http://www.nrcan.gc.ca/~NACS2001/Technical% 20Program/Abstracts/Wednesday/Session%203/120.pdf
