Flame retardancy effects of zinc borate and nanoclay in ABS, and boron compounds in PET
Özkaraca, Ayşe Çağıl; Kaynak, Cevdet; Department of Metallurgical and Materials Engineering (2011)
In this thesis there were two main purposes, the first one being to investigate effects of zinc borate (ZB) on the flammability behavior of ABS when used with and without a traditional brominated flame retardant (BFR) / antimony trioxide (AO) system. The second purpose was to investigate contribution of nanoclays (NC) to the flame retardancy performance of the same traditional BFR compound with various combinations of AO and ZB again in ABS matrix. For these purposes, materials were melt compounded by using...

Synthesis of carborane derivatives for characterization of carbocations
Doğan, Sevban; Akdağ, Akın; Department of Chemistry (2019)
Weakly coordinating anions are extremely versatile species for capturing and characterizing cationic intermediates. Among these anions, carboranes and some boranes are known to be the most weakly coordinating anions. In this thesis, the carboranes and boranes were synthesized in order to capture and characterize unusual carbocations. B11H14-was synthesized from NaBH4. Undecaborate was converted to B10H14 by oxidation and extrusion of one boron vertex. The B10H14 was successfully converted to ortho-carborane...
Investigation of neutron sensitivity of un-doped and Dy-doped CaB4O7 for thermoluminescence applications
Iflazoglu, Sera; Yılmaz, Ayşen; KAFADAR, VURAL EMİR; YAZICI, AHMET NECMEDDİN (2018-09-01)
In this study, thermoluminescence characteristics of un-doped and Dy-doped calcium tetraborate (CaB4O7) compounds are reported. The polycrystalline powder samples of un-doped and Dy-doped CaB4O7 were prepared by a solid-state reaction at high-temperature method. The identification and characteristics of the obtained compounds were determined by X-ray diffraction, Fourier transform infrared analysis, differential thermal analysis, thermogravimetric analysis, and scanning electron microscopy. The glow curves ...
