Several charred plant and charcoal samples from various stratigraphic levels of the Neolithic Site, 1 Catalhtoyuk - Turkey, were dated in the AMS facility of Purdue University (PRIME Lab). Radiocarbon dates reveal a complicated chronology, as was foreseen from archeological investigations. Our measurements suggest that this unique Neolithic town may have been initiated at the East mound around 8390 BP.


DSC study of the combustion properties of turkish coals
Ozbas, K.E.; Kök, Mustafa Verşan; Hicyilmaz, C. (Springer Science and Business Media LLC, 2003-01-01)
In this research, differential scanning calorimetry (DSC) was used to determine the combustion behavior and kinetic analysis of raw and cleaned coal samples of different size fractions. DSC curves of the three coal samples (Soma, Tuncbilek and Afsin Elbistan) showed two reaction regions. The first reaction region was due to moisture loss (endothermic) and observed in the temperature range of ambient to 150°C. The second region was the exothermic region due to the combustion and observed in the temperature r...
New phosphine oxide aziridinyl phosphonates as chiral Lewis bases for the Abramov-type phosphonylation of aldehydes
Doğan, Özdemir; Aygun, Muhittin (Elsevier BV, 2013-05-31)
A series of Lewis bases were screened for Abramov-type phosphine additions to aldehydes. A novel phosphine oxide aziridinyl phosphonate POAP-A was found to be better than the others in forming the product in 96% yield and with 42% ee. The absolute configuration of the newly synthesized POAP Lewis bases was determined by single-crystal X-ray analysis.
Thermal characteristics and kinetics of crude oils and SARA fractions
Kök, Mustafa Verşan (Elsevier BV, 2013-10-10)
In this study, two Turkish crude oils from southeastern part of Turkey and their saturate, aromatic and resin fractions were analyzed by thermogravimetric analysis (TGA). The experiments were performed at three different heating rates (5, 10, 15 degrees C/min) under air atmosphere. Two different reaction regions were observed from thermogravimetry (TG), differential thermogravimetry (DTG) curves due to the oxidative degradation of crude oil components. From TGA curves, it was detected that the heavier fract...

The interaction of hydrogen on potassium promoted catalysts prepared by both sequential and co-impregnation methods was studied by proton NMR spectroscopy. Potassium addition decreased the amounts of both hydrogen adsorbed on the metal (site blocking) and the support hydroxyl groups. No evidence for a ruthenium-mediated (through-metal) electronic interaction between potassium species and adsorbed hydrogen was found. During catalyst preparation, potassium was incorporated on the support by an exchange with t...
3,5-Dimethylpyrazolium Chlorochromate(VI): An Efficient Reagent for Solvent-Free Oxidation of Organic Substrates
Özdemir, Melek (Informa UK Limited, 2012-01-01)
A new chromium(VI) reagent 3,5-dimethylpyrazolium chlorochromate, C5H8N2H[CrO3Cl] (DmpzHCC), was synthesized and used for the selective oxidation of various organic compounds under solvent-free conditions with high efficiency. This new compound has certain advantages over its companion analogues in terms of controlled acidity, amount of oxidant, lack of solvent, short reaction times, and high yields.
