Evaluation of the alkali reactivity of cherts from Turkey
Bektas, F.; Topal, Tamer; Göncüoğlu, Mehmet Cemal; TURANLI, LUTFULLAH (2008-06-01)
Chert, which is a crypto and/or microcrystalline sedimentary rock, may lead to alkali-silica reaction in concrete when the conditions are favorable. However, cherts vary in composition and consequently may demonstrate different reaction characteristic. In this study, eight different chert types were investigated. Accelerated mortar bar test, ASTM C 1260, was performed on aggregate blends of limestone and chert. Ten sets of mortar bars with varying amount of cherts, 1 to 100%, were tested for each chert type...
Synthesis of furopyrrolone and furopyridazinone derivatives: a new class of compounds
Karahan, Emrah; Balcı, Metin; Department of Chemistry (2011)
Furopyrrolone has a bicyclic structure consisting of furan and a pyrrolone ring. It is isoelectronic with isoindolinone which is also a heterocyclic organic compound. It has a bicyclic structure, consisting of a benzene ring fused to a five-membered nitrogen containing pyrrolone ring. Pyrrolones, pyrrolidines, pyrrolidinones, pyridazines and pyridazinones are precursors to many pharmaceuticals. In this project we developed new synthetic procedures leading to the synthesis of furopyrrolone derivatives. To do...
Investigation of combustion characteristics of indigenous lignite in a 150 kwt circulating fluidized bed combustor
Batu, Aykan; Selçuk, Nevin; Department of Chemical Engineering (2008)
Coal is today the fossil fuel which offers the greatest proven reserves. Due to increasingly stringent environmental legislation, coal fired combustion systems should be based on clean coal combustion technologies. For clean and efficient energy generation from coal reserves, the most suitable technology known to date is the ‘Fluidized Bed Combustion’ technology. Applications of circulating fluidized bed combustion (CFB) technology have been steadily increasing in both capacity and number over the past deca...
Investigation of bioprocess parameters for glucose isomerase production by Bacillus thermoantarcticus
Haykır, Işık; Çalık, Pınar; Department of Chemical Engineering (2007)
In this study, the effects of bioprocess parameters on glucose isomerase roduction by Bacillus thermoantarcticus (DSMZ 9572) were investigated. For his purpose, firstly, in laboratory scale shake-bioreactors, a defined medium was designed in terms of its carbon and nitrogen sources, to achieve the highest glucose isomerase activity. Optimum concentrations of medium components were determined by a statistical approach, namely Response Surface Methodology (RSM). RSM defined the relationship between the respon...
Investigation of concentration profiles in carbon nanotube production reactor
Yalın, Mustafa; Özbelge, H. Önder; Department of Chemical Engineering (2009)
Carbon nanotubes have received considerable attention since their discovery due to their novel properties. They have potential application areas in physics, chemistry and biology. Arc discharge, laser furnace, chemical vapor deposition and floating catalyst methods are the most commonly used methods to produce carbon nanotubes. Although carbon nanotubes have superior properties compared to other materials, they could not be used widely. The main reasons of this are that continuous and large scale production...
