Research ArticleOpen accessEvery word in the titleSynthesis of Mesoporous Titania with Surfactant and its CharacterizationT. Benkacem, N. AgoudjilA mesoporous titania was obtained by gelation from Ti-alkoxide in acidic solutions with addition of surfactant cetyltrimetylammonium bromide (CH3(CH2)15N(CH3)3Br) using a sol-gel process. The effects of surfactant concentration on synthesis of mesoporous titania were studied. The structural characterisation was studied by differential thermal analysis, infrared spectroscopy, X-ray diffraction. Studies by X-ray diffraction showed that crystallisation of TiO2 powder occurs at … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,414 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titlePermeability, Strength and Filtration Performance for Uncoated and Titania-Coated Clay Wastewater FiltersMasturi, Silvia, Mahardika Prasetya Aji et al.Problem statement: Wastewater problems continue to be a relevant issue, particularly in urban areas. One promising low-cost material for manufacturing porous ceramics as water filter is clay. Clays can be blended with other materials such as polymers to obtain functional ceramic materials. Approach: Ceramic wastewater filters were fabricated from clay using both sol-gel and simple mixing methods followed by hot-pressing … …American Journal of Environmental Sciences, Vol. 8, Issue 2 · 29 Feb 2012 · 8,395 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsNano TiO2 Deposited on Crude Mineral and the Photoactivity to the Degradation of ChloroformHaiyan Song, Hongfu Jiang, Xingqing Liu, Guangyao MengSupported TiO2 catalysts have increasingly attracted intention in recent years because of their potential application to photocatalytic degradation of organic pollutants in water and air. In this work, nano TiO2 particles deposited on crude nonmetallic mineral were prepared by a Sol-gel process, the photocatalyst for degradation of chloroform was tested and optimized with respect to TiO2 loading, catalyst dosage and … …American Journal of Environmental Sciences, Vol. 2, Issue 2 · 30 Jun 2006 · 7,368 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMIXED CONVECTION BOUNDARY LAYER FLOW ON A VERTICAL SURFACE IN A POROUS MEDIUM SATURATED BY A NANOFLUID WITH SUCTION OR INJECTIONM. H.M. Yasin, N. M. Arifin, R. Nazar et al.An analysis of the steady mixed convection boundary layer flow past a vertical permeable surface embedded in a porous medium saturated by a nanofluid is performed in this study. Numerical solutions of the similarity equations are obtained using the shooting method. Three types of metallic or nonmetallic nanoparticles, namely Copper (Cu), Alumina (Al2O3) and Titania (TiO2) are considered by using … …Journal of Mathematics and Statistics, Vol. 9, Issue 2 · 10 May 2013 · 7,165 accessesView PDF Cite
