Effect of initial water content and calcination temperature on photocatalytic properties of TiO2 nanopowders synthesized by the sol-gel process
Agartan, Lutfi; Kapusuz, Derya; PARK, JONGEE; Öztürk, Abdullah (2015-12-01)
The effects of initial water content and calcination temperature on sol gel synthesized TiO2 powders were studied. Mother solutions had water/Ti-precursor mole ratios (R ratio) of 1, 5, 10, and 50. Dried aerogels were calcined for 3 h at temperatures of 300, 400, and 500 degrees C to obtain crystallized TiO2 nanopowders in the range of 15-30 nm. PE-scanning electron microscopy and X-ray diffraction techniques were employed to investigate the morphological and structural properties of the nanopowders synthes...

Effect of cooling rate on microstructure and high temperature stability of rapidly solidified Al-Fe-V-Si alloys
Kalkanlı, Ali (Informa UK Limited, 1999-01-01)
Recently, AI-Fe-V-Si alloys have received more attention owing to their high temperature stability associated with vanadium rich precipitates and silicides. In this work, a series of alloys was prepared and processed by melt spinning and gas atomisation to observe the effect of solidification rate on crystal structures existing in both as cast and heat treated conditions. This study covers their microstructural examination and crystallography. The composition of these alloys was Al-(6.8-7.8)Fe-( 1.0-3)V-(1....
Effect of precipitation temperature and organic additives on size and morphology of ZnO nanoparticles
Yildirim, Ozlem Altintas; Durucan, Caner (2012-06-01)
Low temperature (25 degrees C-80 degrees C) synthesis of zinc oxide (ZnO) nanoparticles (<20 nm) at short synthesis periods (similar to 30 min) was achieved by precipitation. The precipitation system was formed using zinc acetate dihydrate as zinc source, ethylene glycol (EG) as solvent and polyvinyl pyrrolidone (PVP) as chelating agent. The size of spherical ZnO nanoparticles was manipulated by the choice of precipitation temperature (13.0 +/- 1.9 nm at 25 degrees C and 9.0 +/- 1.3 nm at 80 degrees C), whi...
Effect of surface type on structural and optical properties of Ag nanoparticles formed by dewetting
Tanyeli, Irem; Nasser, Hisham; ES, FIRAT; Bek, Alpan; Turan, Raşit (2013-09-09)
Integration of an array of Ag nanoparticles in solar cells is expected to increase light trapping through field enhancement and plasmonic scattering. Requirement of Ag nanoparticle decoration of cell surfaces or interfaces at the macro-scale, calls for a self-organized fabrication method such as thermal dewetting. Optical properties of a 2D array of Ag nanoparticles are known to be very sensitive to their shape and size. We show that these parameters depend on the type of the substrate used. We observe that...
