Synthesis of macromolecular catalyst systems and applications
Oğuzkaya, Funda; Tanyeli, Cihangir; Department of Chemistry (2011)
SYNTHESIS OF MACROMOLECULAR CATALYST SYSTEMS AND APPLICATIONS Oğuzkaya, Funda PhD., Department of Chemistry Supervisor: Prof. Dr. Cihangir Tanyeli September 2011, 144 pages The thesis mainly proposed to design macromolecular catalyst systems. Such catalysts should follow the way of "Green Chemistry" with including no metallic ions and have also the ability of reusability. Hence, nitroxide chemistry was chosen as the key point. Catalysts were synthesized with surely including TEMPO as the functional part as ...
Computer simulation of stick-slip motion in machine tool slideways
Bilkay, O; Anlagan, O (Elsevier BV, 2004-04-01)
Especially in CNC (Computer Numerical Control) machine tools, stick-slip motion should be eliminated even at very low sliding speeds. Otherwise, the table begins oscillating around the desired position and exact positioning can never be achieved. In this study, stick-slip motion of plain machine tool slideways is simulated using a two-degree of freedom mathematical model. The governing equations are solved with the help of a mathematical package, MathCad 6.0. The results are compared with experimental ones ...

Glass-ceramics containing only apatite and wollastonite crystals were produced in the system MgO-CaO-SiO2-P2O5-F by the melt casting process. The bioactivity of the glass-ceramics was determined by immersing the glass-ceramics in a simulated body fluid (SBF) and by assessing the resulting apatite formation on the free surface after various immersion durations. A 12-mu m-thick apatite layer formed on the surface of the glass-ceramic containing only apatite crystals after 20 days immersion in SBF. However, th...

Zn-In-Se thin films were fabricated on the ultrasonically cleaned glass substrates masked with clover-shaped geometry by thermal evaporation of its elemental sources. Temperature-dependent conductivity characteristics of the films were investigated under dark and illuminated conditions. The semiconductor type of the films was found as n-type by thermal probe test. According to the van der Pauw technique, the dark electrical conductivity analyses showed that the variations of conductivity of unannealed and a...
Electromagnetic form factors of the rho meson in light cone QCD sum rules
Alıyev, Tahmasıb; Savcı, Mustafa (American Physical Society (APS), 2004-11-01)
We investigate the electromagnetic form factors of the rho meson in light cone QCD sum rules. We find that the ratio of the magnetic and charge form factors is larger than 2 at all values of Q(2), (Q(2)greater than or equal to0.5 GeV2). The values of the individual form factors at fixed values of Q(2) predicted by the light cone QCD sum rules are quite different compared to the results of other approaches. These results can be checked in the future, when more precise data on rho meson form factors is availa...
