Charity programmes : representation of povertry in Turkish television
Çamur, Aysel; Erdoğan, Necmi; Department of Political Science and Public Administration (2004)
This thesis analyses the representation of poverty in the charity programmes broadcast on Turkish television, namely Deniz Feneri, Kimse Yok mu, Yarinlar Umut Olsun and Yolcu. It examines the continuities, discontinuities and breaks in the representation of poor with reference to Turkish cinema, novel and media. Critical discourse analysis of the charity programmes indicates that poverty is legitimised and naturalised, being made no reference to social, economic and political context of poverty. The constru...
Processing and characterization of poly(ethylene terephthalate) based composites
Kılınç, Mert; Bayram, Göknur; Department of Chemical Engineering (2004)
Polymeric composites are any of the combinations or compositions that comprise two or more materials as separate phases, at least one of which is a polymer. By mixing a polymer with another material, such as glass, carbon, or another polymer, it is often possible to improve the desired properties of the polymer. In this study, ternary composites were prepared by using recycled poly(ethylene terephthalate), PET as the matrix material, short glass fiber (SGF) as the reinforcing filler and thermoplastic elasto...
Enhancing electrochromic properties of polypyrrole by silsesquioxane nanocages
Ak, Metin; Gacal Özcan, Burçin; Kışkan, Barış; Yağcı, Yusuf; Toppare, Levent Kamil (Elsevier BV, 2008-04-29)
A new monomer, octa(thiophenephenyl)silsesquioxane (OThiophenePS) was synthesized via click chemistry. The chemical structure of OThiophenePS was characterized by nuclear magnetic resonance (H-1 NMR) and Fourier transform infrared (FT-IR) spectroscopies. Electrochemical polymerization of pyrrole with OThiophenePS was performed resulting in polypyrrole-attached, polyhedral oligomeric silsesquioxane (OPS-PPy). The spectroelectrochemical studies show that the electrochromic properties of (OPS-PPy) are superior...
Fabrication of a Novel Polymeric Scaffold for Amperometric Laccase Biosensor
Soylemez, Saniye; Bekmezci, Aybüke; Göker, Seza; Toppare, Levent Kamil (Wiley, 2019-11-14)
Present work displays the preparation of an electrochemical biosensor using a conjugated polymer and laccase enzyme for catechol quantification in samples. The biosensing system is based on an enzyme immobilization on polymer modified graphite transducer surface. For that purpose, a random conjugated polymer, thienothiophene-benzoxadiazole-alt-benzodithiophene (BOTT), was coated onto a graphite electrode surface via drop casting method followed by immobilization of a biomolecule (laccase) for sensing experi...
Degradation of EPDM via gamma irradiation and possible use of EPDM in radioactive waste management
Hacıoğlu, Fırat; Usanmaz, Ali; Özdemir, Tonguç; Department of Polymer Science and Technology (2010)
In this study, degradation of ethylene propylene diene terpolymer (EPDM) via gamma radiation and possible use of EPDM in radioactive waste management were investigated. In estimation of radiation stability and possible use of EPDM in radioactive waste management, dose rate (both high and low), irradiation environment (in water and in air), additives (carbon black, zinc oxide, plasticizer) used in formulation, peroxide type (either aliphatic or aromatic) and content were parameters which were analyzed. Three...
