A sol-gel process for producing microspheres of low density alumina has been developed. A Dispal alumina sol and aluminum monohydrate were used as starting materials. Microspheres with spherical shape and controllable size have been produced by using a drop generation technique, The technique consists of producing a continuous stream Of uniform droplets of alumina sol and then converting the drops into a rigid form by exposing them to an ammonium hydroxide gelation medium. By using this technique. alumina spheres with surface area 351 m(2)g(-1) and pore size 10.7 Adegrees have been prepared.

Fabrication of high density alumina ceramics from nanopowders through colloidal processing.
Kayacı, Hüseyin Utkucan; Çınar, Simge; Department of Metallurgical and Materials Engineering (2020)
Utilizing nanopowders in production of fully dense materials with fine grain structures is highly advantageous, particularly where high mechanical properties are desired. Besides, recently developed techniques, such as 3D-printing of ceramics, may require high solids content suspensions. Despite the advantages of slurry based processing of oxide ceramics, production of nano-structured high density bodies is still a challenge. The main limitation in colloidal processing of nanopowders is their unexpectedly h...
Investigation of the effects of initial substrate and biomass concentrations and light intensity on photofermentative hydrogen gas production
Akman, Melih Can; Erguder, Tuba Hande; Gündüz, Ufuk; Eroglu, Inci (2014-01-01)
Biohydrogen, which can be produced by dark fermentation and photofermentation processes, is a renewable and clean approach for hydrogen production. In this study, it was aimed to determine the operational conditions which satisfy the highest photofermentative hydrogen production rate in batch reactors. To that purpose, the effects of initial substrate concentration, initial volatile suspended solids (VSS) concentration and light intensity on photofermentation process were investigated by using Response Surf...
Investigation of the effects of initial substrate and biomass concentrations and light intensity on photofermentative hydrogen gas production by Response Surface Methodology
Akman, Melih Can; Bayramoğlu, Tuba Hande; Gündüz, Ufuk; EROĞLU, İNCİ (2015-04-27)
Biohydrogen, which can be produced by dark fermentation and photofermentation processes, is a renewable and clean approach for hydrogen production. In this study, it was aimed to determine the operational conditions which satisfy the highest photofermentative hydrogen production rate in batch reactors. To that purpose, the effects of initial substrate concentration, initial volatile suspended solids (VSS) concentration and light intensity on photofermentation process, and their interactive effects were inve...
Analysis of single phase convective heat transfer in microchannels with variable thermal conductivity and variable viscosity
Gözükara, Arif Cem; Güvenç Yazıcıoğlu, Almıla; Department of Mechanical Engineering (2010)
In this study simultaneously developing single phase, laminar and incompressible flow in a micro gap between parallel plates is numerically analyzed by including the effect of variation in thermal conductivity and viscosity with temperature. Variable property solutions for continuity, momentum and energy equations are performed in a coupled manner, for air as a Newtonian fluid. In these analyses the rarefaction effect, which is important for the slip flow regime, is taken into account by imposing slip veloc...
Modeling of particle filled resin impregnation in compression resin transfer molding
Şaş, Hatice Sinem; Erdal Erdoğmuş, Merve; Department of Mechanical Engineering (2010)
Compression Resin Transfer Molding (CRTM) is an advanced liquid molding process for producing continuous fiber-reinforced composite parts in relatively large dimensions and with high fiber volume fractions. This thesis investigates this process for the purpose of producing continuous fiber reinforced composites with particle fillers. In many composites, fillers are used within the resin for various reasons such as cost reduction and improvement of properties. However, the presence of fillers in a process in...
