Stabilization of an expansive soil using phosphogypsum
Özkan, İlyas; Çokça, Erdal; Department of Civil Engineering (2015)
Expansive soils are a worldwide problem that poses several challenges for civil engineers. Such soils swell when given an access to water and shrink when they dry out. The most common and economical method for stabilizing these soils is using admixtures that prevent volume changes. Studies for treatment of expansive soils with phosphogypsum are very limited in literature. In this study the effect of phosphogypsum (PG) in reducing the swelling potential is examined. The expansive soil was prepared in the lab...
Synthesis and characterization of waterborne and phosphorus containing flame-retardant polyurethane coatings
Çelebi, Funda; Aras, Leyla; Gündüz, Güngör; Department of Chemistry (2002)
In this study, phosphorus containing flame retardant water-dispersed polyurethane paints were produced by incorporating different amounts of phosphorus compound onto the polyurethane main chain. The novel flame retardant compound was synthesized in three steps. In the first step, monobenzalpentaerythritol was produced from benzaldehyde and pentaerythritol. In the second step, phosphorylation of monobenzal pentaerythritol was performed. Final step includes the formation of phosphorus phenyl dihydroxyl from t...
Process development for continuous photofermentative hydrogen production
Boran, Efe; Eroğlu, İnci; Özgür, Ebru; Department of Chemical Engineering (2011)
By the integration of dark and photo fermentative hydrogen production processes, higher yields of hydrogen can be obtained from biomass. In the first step, biomass is utilized for hydrogen production by dark fermentation and in the second step, the effluent of dark fermentation is further utilized for hydrogen production by photofermentation using photosynthetic purple non-sulfur bacteria. The purpose of this study was to develop a solar pilot scale tubular photobioreactor (PBR) for continuous photo ferment...
New quinoxaline and selenophene based benzodithiophene bearing conjugated polymers for photovoltaic applications
Çalışkan, Meriç; Çırpan, Ali; Department of Chemistry (2019)
The current research trends have greatly focused on the development of new low band gap conjugated polymers featuring alternating donor-acceptor unities to achieve remarkable power conversion efficiencies for OPV devices. For this purpose, a series of new quinoxaline and selenophene based BDT bearing conjugated polymers namely P1, P2 and P3 were synthesized using Stille cross coupling reaction. The 2-(2-Octyldodecyl)selenophene ring was attached to 4th and 8th positions of phenyl ring in BDT to obtain donor...
Studies on photochemical vapor generation of selenium
Çetmeli , Melis; Ertaş, Gülay; Department of Chemistry (2019)
Selenium is a significant trace element for human health. Selenium can be essential or toxic for human body depending on its concentration. Within the scope of this thesis, photochemical vapor generation tungsten coil atomization technique has been studied for the determination of selenium. Volatile selenium compounds were generated by exposure of UV light of the solution containing selenium and acetic acid. To increase sensitivity of photochemical vapor generation system, the technique was combined with tu...
