Production and characterization of magnesium oxychloride cement based polishing bricks for polishing of ceramic tiles
Özer, Muhammed Said; Öztürk, Abdullah; Department of Metallurgical and Materials Engineering (2008)
Magnesium oxychloride cement (MOC) based grinding and polishing bricks developed for polishing of granite based ceramic tiles were produced and characterized. For surface grinding 46 and 180 grit size SiO2 powder embedded MOC based abrasive bricks; for polishing 600 and 1200 grit size SiC powder embedded MOC based abrasive bricks followed by neat (unreinforced) MOC pastes were applied on ceramic tiles. Three different neat MOC pastes depending on MgO/MgCl2 molar ratio in the paste e.g. 6/1, 7/1, and 8/1, we...

Recovery of tungsten from tungsten bearing compounds
Erdoğan, Metehan; Karakaya, İshak; Department of Metallurgical and Materials Engineering (2013)
Extensive research in recent years has failed to develop any essentially new method of large scale tungsten production. A new tungsten powder production technique from calcium tungstate (CaWO4) has recently been reported. In this thesis, this technique was further explored from the aspects of electrochemical reduction mechanism and kinetics, applicability to scheelite concentrates and industrial production. Cyclic voltammetry, constant potential and constant current electrochemical reduction tests were perf...
Synthesis of paracyclophane-peptide based semiconductive peptide hydrogels
Dolgun, Volkan; Özçubukçu, Salih; Department of Chemistry (2017)
Self-assembling peptide hydrogels are becoming an emerging field especially in last decades. Application of these hydrogel forming peptides in biomedical materials, organic electronic devices and tissue engineering is a challenging topic which requires alternative structures to get better and to be easily applied systems. [2.2]Paracyclophane has an interesting structure which two benzene rings are bound to each other with a bridge containing 2 carbons. It is known that the distance between two benzene rings...
Synthesis of 2,3-disubstituted thiophenes from ketoalkynes
Vatansever, Erol Can; Balcı, Metin; Department of Chemistry (2013)
Synthesis of thiophene containing compounds are of particular interest in synthetic organic chemistry. Besides the importance for synthetic organic chemistry, thiophene derivatives are used in applied research such as drug synthesis and study of functional materials. In this thesis, a new methodology for developing of 2,3-disubstituted thiophenes was developed. This methodology utilizes readily available compounds in a two-step synthesis to provide a facile access to the 2,3-disubstituted thiophenes. In the...
