Development of amino functionalized POSS based (3-Glycidoxypropyl)trimethoxysilane hybrid sol-gel coatings for aircraft applications
Varan, Dilara Çisel; Öztürk, Abdullah; Department of Metallurgical and Materials Engineering (2021-12)
An amino functionalized and 50 percent amphiphilic polyhedral oligomeric silsesquioxane (POSS) based (3-Glycidoxypropyl)trimethoxysilane (GPTMS) sol-gel reaction was carried out under extreme basic conditions. Amount of POSS per 1 mol of GPTMS was varied at molar ratios of 0.2, 0.4, and 0.6. The sol-gel product was coated on the aluminium 2024 alloy samples with immersion technique and thermally treated to improve corrosion resistance of the alloy. Influence of aging durations (1, 3, and 6 days) on the sol-...
Development of solid sodium borohydride hydrogen gas generator for portable pem fuel cell applications
Boran, Aslı; Eroğlu, İnci; Department of Chemical Engineering (2018)
Hydrogen is considered as a promising candidate to replace fossil fuels. For implementing a hydrogen based infrastructure, hydrogen storage is the mainobstacle that is needed to be overcome. Being boron based compound, sodium borohydride, NaBH4, is a convenient hydrogen storage material for applications like unmanned air vehicles. There are several issues behind commercialization of NaBH4 hydrolysis systems. This doctorate thesis aims to be solution of NaBH4 hydrolysis system by highlighting three main cont...
Development of polybenzimidazole/graphene oxide composite membranes for high temperature PEM fuel cells
Uregen, Nurhan; Pehlivanoglu, Kubra; Ozdemir, Yagmur; DEVRİM, YILSER (2017-01-26)
In this study, phosphoric acid doped Polybenzimidazole/Graphene Oxide (PBI/GO) nano composite membranes were prepared by dispersion of various amounts of GO in PBI polymer matrix followed by phosphoric acid doping for high temperature proton exchange membrane fuel cell (HT-PEMFC) application. The structure of the PBI/GO composite membranes was investigated by X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and by thermogravimetric analysis (TGA). The introduction of GO into the FBI polymer matri...
Development of diffusion bonded materials for electronics cooling applications
Atabay, Sıla Ece; Dericioğlu, Arcan Fehmi; Department of Metallurgical and Materials Engineering (2017)
Failure of most of the electronic systems are originating from deterioration of the components due to excessive heat flux generation. The unstoppable demand for more complex and miniaturized electronic systems makes the development of more suitable and feasible production methods for their cooling systems and components compulsory. In the scope of this study diffusion bonding behavior of the aluminum (Al) 6063 alloy was investigated to make this bonding method and alloy system available for the electronic c...
Development of hole transport transparent conductive electrodes for n-type crystalline silicon solar cells
Akdemir, Ozan; Bek, Alpan; İmer, Muhsine Bilge; Department of Micro and Nanotechnology (2018)
Conventional transparent conductive electrodes (TCEs) used in crystal silicon (c-Si) solar cells are commonly made of indium tin oxide (ITO) which provides low sheet resistance and high transparency. However, due to indium scarcity, ITO layers increase the fabrication cost; thus, alternative TCEs, such as fluorine-doped tin oxide (FTO), zinc oxide (ZnO), metal nanowires and Oxide/Metal/Oxide (OMO) multilayers, are being investigated. Conventional solar cells also make use of doped layers, to create the junc...
