The effects of hydrogenated tallow amine acetate on rutile and ilmenite surfaces

The Effect of dispersed phase feed rate on the production of pickering emulsions Dönmez, Dila; Ayrancı Tansık, İnci; Department of Chemical Engineering (2018) Emulsions are fundamental in many applications such as food, petroleum, detergent, pharmaceutical and cosmetic industries. Pickering emulsions are defined as emulsions of any type, either oil-in water, water-in-oil or even multiple, stabilized by solid particles instead of surfactants. Solid particles may prevent the droplets from coalescing by getting adsorbed at the interface, and thus stabilizing the emulsion. Pickering emulsions have more advantages over emulsions stabilized by surfactants in terms of s...
The effect of annealing conditions on the red photoluminescence of nanocrystalline Si/SiO 2 films Wu, Xiaochun; Bek, Alpan; Bittner, Alexander M.; Eggs, Ch.; Ossadnik, Ch.; VEPREK, S (Elsevier BV, 2003-02-03) Nanocrystalline Si (nc-Si) embedded in a SiO2 matrix, fabricated by plasma CVD and a subsequent post-treatment shows a broad red photoluminescence (PL). In this paper, the effects of annealing temperature, atmosphere and time on the red PL from 1.75 to 1.5 eV have been investigated in detail. It is found that the spectral shift and the PL intensity from 1.75 to 1.5 eV show a strong and unique dependence on annealing conditions. For a PL approximately 1.75 eV, upon 400 °C forming gas annealing, the spectral ...
The effects of feed size distribution on confined-bed comminution of quartz and calcite in piston-die press Hoşten, Çetin; Cimilli, H. (Elsevier BV, 2009-05-16) Packing characteristics of particle beds, determined mainly by the particle size distribution, exert a critical influence on the interparticle breakage of minerals in confined beds under compression. This paper is concerned with the effects of feed size distribution on characteristic phenomena of confined-bed comminution. Minus 3.35-mm quartz and calcite feeds were prepared by proportionately mixing previously classified narrow-size fractions so as to construct particle size distributions having the Gaudin-...

The effect of reed beds on wave attenuation and suspended sediment concentration Oğuz, Elif; Koroglu, Aysun; Kabdaşlı, Mehmet Sedat (Coastal Education and Research Foundation, 2013-01-01) The effect of emergent and submerged vegetation on uniform and oscillatory flow conditions has been intensively studied by researchers in the last two decades. It has been determined that vegetation affects wave characteristics and cause wave attenuation especially in shallow waters where wave orbitals are in interaction with vegetation. Consequently they affect sediment deposition and resuspension acting as a sink. The aim of this study is to determine wave attenuation due to vegetation, and to identify th...
