Lead(II) adsorption on thiourea treated graphene oxide in aqueous solutions
Ersoy Özmen, Güliz; Gökağaç Arslan, Gülsün; Department of Chemistry (2019)
Lead poisoning has serious damages on the human health. The Pb+2 contamination in water affects the kidneys and nervous, cardiovascular, immune, reproductive and developmental systems resulting in Alzheimer's, Parkinson's and Schizophrenia diseases. One of the ways that human are exposed to lead is through water resources, therefore, removing lead from aqueous solutions is a significant issue in our everyday life. It is known that graphene oxide (GO) is a promising material to remove Pb+2 ions due to its hi...
Interface Engineering with a Thienothiophene-Based Ammonium Salt for Realization of Semitransparent Perovskite Solar Cells with Enhanced Efficiency and Improved Stability
Güneş, Ümmügülsüm; Günbaş, Emrullah Görkem; Department of Chemistry (2021-9)
The stability issues of perovskite solar cells (PSCs) is one of the most important factors preventing commercialization. Various approaches have been proposed to overcome this problem, and among them, interface engineering is highlighted as one of the most convenient ways. In this study, a thienothiophene based ammonium salt (TTMAI) was coated on 3D FAMA (((FAPbI3)1−x(MAPbBr3)x))-based perovskite. GIXRD and SEM analysis revealed that TTMAI did not incorporate in the 3D perovskite but only resulted in a chan...
3D synthetic human face modelling tool based on T-spline surfaces
Aydoğan, Ali; Ulusoy, İlkay; Department of Electrical and Electronics Engineering (2007)
In this thesis work, a 3D Synthetic Human Face Modelling Software is implemented using C++ and OpenGL. Bézier surfaces, B-spline surfaces, Nonuniform Rational B-spline surfaces, Hierarchical B-Spline surfaces and T-spline surfaces are evaluated as options for the surface description method. T-spline surfaces are chosen since they are found to be superior considering the requirements of the work. In the modelling process, a modular approach is followed. Firstly, high detailed facial regions (i.e. nose, eyes,...
Syntheses and optoelectronic applications of thiadiazolo quinoxaline bearing alternating conjugated copolymers
Ataoğlu, Emre; Çırpan, Ali; Ünalan, Hüsnü Emrah; Department of Polymer Science and Technology (2016)
Donor-acceptor type conjugated polymers containing thiadiazolo quinoxaline and benzodithiophene derivatives were used as photoactive material for organic solar cell. The alkoxy- substituted benzo[1,2-b;4,5-b’]dithiophene (BDT) monomer, 2,6bis(trimethyltin)-4,8-di(2-ethylhexyloxyl)benzo[1,2-b;4,5-b’]dithiophene, was polymerized with 4,9-dibromo-[1,2,5]thiadiazolo[3,4-g]quinoxaline through a Pd(0)catalyzed Stille coupling reaction. In order to improve the interchain interactions between polymer chains, an alk...
Preparation and characterization of PT nanocatalysts supported by thiourea-treated GO nanoparticles : the application to anodic process of DMFC
Karaosmanoğlu, Toprak Seda; Gökağaç Arslan, Gülsün; Department of Chemistry (2017)
In this thesis, Pt / graphene oxide (Pt / GO), Pt / reduced GO (Pt / 24 h thiourea-treated GO), Pt / 20 min thiourea-treated GO, Pt/ 2 h thiourea-treated GO, and Pt / 5 h thiourea-treated GO nanocatalysts were prepared for methanol oxidation reaction (MOR). The last three ones were synthesized for the first time. They were characterized by FTIR, UV-Vis spectroscopy, acid-base back titration, XRD, XPS, TEM and ICP-MS techniques. Their electrochemical properties and performances toward methanol oxidation reac...
