Synthetic strategy directed towards the synthesis of bicyclo[3.3.0]octa-3,5,8-triene-2,7-dione
Atalar, Taner; Balcı, Metin; Department of Chemistry (2004)
Although the chemistry of benzenoid and nonbenzenoid quinones have been the subject of extensive theoretical and experimental studies, the extent of our present understanding regarding the geometries and stabilities of quinones of pentalene is meager. After studying the existence of cyclopentadienone and its reactivity as a diene and dienophile in the literature, the study of some related species, particularly the ones with fully unsaturated pentalenic structures were started. In this thesis, the elusive co...
Comparative evaluation of steel mesh, steel fiber and high performance polypropylene fiber-reinforced concrete in panel/beam tests
Ceylan, Semih; Turanlı, Lütfullah; Department of Civil Engineering (2014)
Comparison of concrete mixtures containing steel mesh, steel fiber and polypropylene fibers were evaluated in terms of toughness, flexural strength, compressive strength and split tensile strength. Five types of concrete were prepared with steel mesh, steel fiber and polypropylene fiber with the identical water/cement (w/c) ratio and the identical workability. 10x60x60 cm plates, 8x8x32 cm beams and 10x20 cm cylindrical concrete specimens were prepared. Compressive strength, split-tensile strength and tough...
Properties and hydration of cementitious systems containing low, moderate and high amounts of natural zeolites
Uzal, Burak; Turanlı, Lutfullah; Department of Civil Engineering (2007)
The extent of the benefits provided by use of SCMs in cementitious systems increases as their percentage amounts in total binder increases. However, the proportion of SCMs in cementitious systems is limited, especially for natural pozzolans, by some factors such as increase in water requirement and decrease in rate of strength development. Therefore investigations are needed to increase the amount of natural pozzolans in blended cements or in concrete as much as possible without decreasing their performance...
Generation of aryl radicals from arylboronic acids by manganese(III) acetate: Synthesis of biaryls and heterobiaryls
Demir, Ayhan Sıtkı; Reis, O; Emrullahoglu, M (2003-01-24)
The efficient generation of aryl radicals from arylboronic acids by manganese(III) acetate is described. In aromatic solvents, in situ generated aryl radicals afford the corresponding biaryls in very good yields. This method works selectively, and yields are better than those from similar, previously described methods. Arylboronic acids carrying sensitive functional groups also work efficiently.
Sorption of C8 aromatics on MCM-41
Ali, Baraa Abbas; Yücel, Hayrettin; Department of Chemical Engineering (2010)
The discovery of MCM-41 materials have attracted substantial research attention due to the remarkable features of these materials including a narrow pore size distribution, high surface area, high pore volume, and high thermal and hydrothermal stability, as well as, parallel hexagonal arrangement of uniform cylindrical pores without pore channel intersection. These well-defined structural characteristics make them ideal media to study the adsorption, catalysis, ion exchange, and separation. MCM-41 sample us...
