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 ...
Dynamic frictional contact problems involving elastic coatings
BALCI, MEHMET NURULLAH; Dağ, Serkan (Elsevier BV, 2018-08-01)
This paper presents a general theory of dynamic frictional contact of elastic coatings pressed against by a rigid punch moving with a constant speed. Governing equations of elastodynamics are solved by applying Galilean and Fourier transformations. The contact problem is then reduced to a singular integral equation, which is solved numerically. Developed procedures are verified through comparisons made to the available computational and analytical results. Parametric analyses illustrate the influences of pu...
Electronic and structural properties of armchair SWCNT/TiO2(110)-(1 x 2) system
Tayran, C.; ÇAKMAK, MELEK; Elliatioglu, S. (Elsevier BV, 2011-03-01)
We have presented structural and electronic properties of single-walled carbon nanotubes (CNTs) with armchair chirality on the reconstructed rutile TiO2(110)-(1 x 2) surface by means of ab initio calculations using density functional theory. For the TiO2 surface reconstruction, we have adopted an added-row model which was experimentally proposed in parallel to STM patterns and theoretically agreed by first principle calculations. In this work, we have studied, as examples, two CNTs with different sizes, (3,...

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...
Atomic and electronic structure of group-IV adsorbates on the GaAs(001)-(1 x 2) surface
Usanmaz, D.; ÇAKMAK, MELEK; Ellialtıoğlu, Süleyman Şinasi (Elsevier BV, 2009-09-01)
Ab initio calculations, based on pseudopotentials and density functional theory, have been performed to investigate the atomic and electronic structure of the group-IV adsorbates (C, Si, Ge, Sn, and Pb) on the GaAs(001)-(1 x 2) surface considered in two different models: (i) non-segregated Ga-IV-capped structure and (ii) segregated structure in which the group-IV atoms occupying the second layer while the As atom floats to the surface. The non-segregated structure is energetically more favorable than the se...
