Investigation of fly ash characteristics on zeolite 4A synthesis
Akın, Süleyman Şener; Kazanç Özerinç, Feyza; Department of Micro and Nanotechnology (2019)
There is lack of information about the relation between the candidate raw material fly ash and end product, Zeolite 4A.This study aims to fill the gap in the literature through controlled ash production experiments, characterization studies and Zeolite 4A synthesis. As a result of studies, the nucleation behaviour of the alkali fusion product obtained from fly ash was demonstrated and the most crystalline Zeolite 4A with cubic morphology were obtained from Seyitömer fly ash with alkali fusion product of Si/...
Investigation of Fluorine Atom Effect on Benzothiadiazole Acceptor Unit in Donor Acceptor Donor Systems

Synthesis of two new pi-conjugated monomers containing fluorine substituted benzothiadiazoles as acceptor units and 3,4-ethylenedioxythiophene (EDOT) as donor unit was accomplished by facilitating Stille cross-coupling reactions (4,7-bis(2,3-dihydrothieno[3,4-b][1,4] dioxin-5-yl)-5-fluorobenzo[c][1,2,5] thiadiazole (E2BTD-F) and 4,7-bis(2,3-dihydrothieno [3,4-b][1,4] dioxin-5-yl)-5,6-difluorobenzo[c][1,2,5] thiadiazole (E2BTD-2F)). NMR and HRMS spectra of newly synthesized compounds are in agreement with th...
Investigation of optoelectronic properties of benzotriazole and thiazole bearing conjugated polymers
Ünay, Hakan; Çırpan, Ali; Department of Polymer Science and Technology (2019)
This thesis deals with the design, synthesis and characterization of conjugated polymers P1 and P2 that have potential application in organic solar cell. Polymer design was accomplished by using band gap engineering method. According to that, benzodithiophene (BDT) and silafluorene were chosen as donor groups in P1 and P2 respectively. The acceptor parts were the same for both polymers including benzotriazole (BTZ) and thiazole group. According to electrochemical studies both polymers were having n-dopable ...
Investigation of surface properties of quince seed extract as a novel polymeric surfactant
Kirtil, Emrah; Svitova, Tatyana; Radke, Clayton J.; Öztop, Halil Mecit; Şahin, Serpil (2022-02-01)
© 2021 Elsevier LtdIn recent years, there is a growing trend from both academia and the industry towards the use of “clean-labeled” ingredients obtained from renewable resources. Proteins and polysaccharides, in particular, are becoming increasingly popular as alternatives to already well-established synthetic surfactants. Quince seeds are a relatively novel hydrocolloid source that has recently raised interest among researchers due to their strong surface activity and viscosity-enhancing properties. This s...
Investigation of graphene-integrated tunable metamaterials in THz regime
Demir, Şimşek; Sabah, Cumali (2018-05-01)
A metallic fishnet metamaterial structure in sub-THz region is presented. The proposed structure is based on hexagonal resonators. Simulations have been performed by a 3D full-wave electromagnetic simulator and a negative refractive index has been observed at the frequency range between 0.55 and 0.70 THz with the help of the graphene layer. In order to observe the effect of the graphene layer, the metamaterial structure has been simulated and examined before and after graphene integration. Significant modif...
