The effects of Dea:water ratio on the properties of ZnO nanofilms obtained by spin coating method
(Elsevier Science, 2014)In this work the ZnO were fabricated with the sol-gel spin coating method and the effects of the Dea:water ratios on the properties of the as-prepared ZnO thin films were determined by using a X-ray diffractometer transmission ... -
The Electrochromic Performances of Single Phase VO2 Nanoparticled Films
(Elsevier Science SA, 2016)In the present work pure phase vanadium oxide VO2 nanoparticled films were synthesized using acetate based sol-gel precursors. The effect of the water: Vanadyl acetylacetonate ratio on electrochemical and structural ... -
Electrochromic properties of heat-treated thin films of CeO2-TiO2-ZrO2 prepared by sol-gel route
(Elsevier Science Bv, 2008)CeO2-TiO2-ZrO2 thin films were prepared using the sol-gel process and deposited on glass and ITO-coated glass substrates via dipcoating technique. The samples were heat treated between 100 and 500 degrees C. The heat ... -
Epidemic models for phase transitions: application to a physical gel
(Taylor & Francis Ltd, 2017)Carrageenan gels are characterized by reversible sol-gel and gel-sol transitions under cooling and heating processes and these transitions are approximated by generalized logistic growth curves. We express the transitions ... -
Modeling the optical properties of WO(3) and WO(3)-SiO(2) thin films
(Elsevier Science Bv, 2008)The optical properties and surface morphology of sol-gel spin coated WO(3) and WO(3)-SiO(2) composite films annealed at 250 and 400 degrees C are investigated. For the purpose of extracting the optical parameters of the ... -
Optical and structural properties of sol-gel made Ce/Ti/Zr mixed oxide thin films as transparent counter electrode for electrochromic devices
(Elsevier Science Bv, 2008)Ce/Ti/Zr mixed oxide thin films were prepared using sol-gel process with mole ratios from 45/5 to 5/45 of Ti/Zr and 50 of Cc and deposited by dip coating technique. Optical electrochromic and structural properties of such ... -
Optical and structural properties of Ta2O5-CeO2 thin films
(Elsevier Science Bv, 2007)In this study the sol-gel spin-coating method has been used to make Ta2O5-CeO2 thin films. These films have been prepared in various composition ratios to observe changes in their optical and structural properties. Reflectance ...
