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...

The formation and characterization of cyclodextrin functionalized polystyrene nanofibers produced by electrospinning
Uyar, Tamer; Havelund, Rasmus; Hacaloğlu, Jale; Zhou, Xingfei; Besenbacher, Flemming; Kingshott, Peter (2009-05-18)
Polystyrene (PS) nanofibers containing the inclusion complex forming beta-cyclodextrin (β-CD) were successfully produced by electrospinning aimed at developing functional fibrous nanowebs. By optimization of the electrospinning parameters, which included varying the relative concentration of PS and β-CD in the solutions, bead-free fibers were produced. Homogeneous solutions of β-CD and PS in dimethylformamide (DMF) were used with concentrations of PS varying from 10% to 25% (w/v, with respect to DMF), and β...
Exciton simulations of the optical properties of several photosynthetic light-harvesting complexes
İşeri, Erkut İnan; Gülen, Demet; Department of Physics (2004)
The work presented in this thesis was aimed to investigate the structure-function relationship of several photosynthetic Light-Harvesting Complexes (LHCs) including Chlorophyll Protein 29 (CP29) and Light-Harvesting Complex II (LHCII) of green plants, and Fenna-Matthews-Olson (FMO) complex of green sulfur bacterium Chlorobium tepidum. Based on the exciton calculations, a model was proposed to the electronic excited states (EES) of both CP29 and LHCII complexes by incorporating a considerable part of the cur...
