Electrochemical synthesis of poly(methylsilyne), and the effect of silicon-based preceramic polymers on the properties of polypropylene based composites
Eroğlu, Damla; Bayram, Göknur; Department of Chemical Engineering (2008)
In the first part of this dissertation, poly(methylsilyne) was produced both in small and large-scales. In the small-scale, the aim was to synthesize the polymer by electrochemical polymerization of methyltrichlorosilane at a constant potential of -6 V supplied by batteries, using sodium dodecyl sulfate (SDS) as the supporting electrolyte. The polymer was characterized by 1H-NMR, FTIR, UV-Visible Spectroscopy and GPC in addition to its distinctive yellow color. The yellow color and the 1H-NMR, FTIR, UV-Visi...
Oxygen-18, deuterium and tritium in the Black Sea and the Sea of Marmara
Rank, D; Ozsoy, E; Salihoglu, I (1999-01-01)
The stable isotopes O-18 and H-2, together with the transient tracer H-3 can be used to identify origins and characteristics of distinct water masses in the Black Sea, and in its smaller neighbour, the Marmara Sea, connected between them and to the Mediterranean Sea through the Straits of Bosphorus and Dardanelles, respectively. Exchange through the system and the water mass formation and evolution are characterised, based on the isotope measurements. Spatial coverage including the shelf and deep regions, w...

Synthesis and characterization of mechanical, thermal and flammability properties of epoxy based nanocomposites
Kop, Erhan; Yılmazer, Ülkü; Department of Chemical Engineering (2007)
Polymer-clay nanocomposites have received a lot of attention because of outstanding improvements in properties when compared with neat polymeric materials. The aim of this study was to prepare epoxy-clay nanocomposites by mixing organically modified montmorillonite with an epoxy resin and to investigate the effects of clay content on the mechanical, thermal and flammability properties of the resultant nanocomposites. The production of the epoxy-clay nanocomposites was accomplished by in-situ polymerization....
