In the title compound, tetracarbonyl[(1,2,5,6-eta)-1,5-cyclooctadiene]molybdenum(0), [MO(C8H12)(CO)(4)], the coordination polyhedron around the metal atom is a distorted octahedron. The Mo-C bond distance for CO groups trans to a C=C unit is significantly shortened [average value 1.948 (8) Angstrom], while the Mo-C bond distances for the cis groups are only slightly shortened [average value 2.031 (8) Angstrom], compared with the values reported for [Mo(CO)(6)]. The average distance of the Mo atom to the midpoints of the olefinic C=C bonds is 2.388 (8) Angstrom.

Electrochemical oxidation and reduction properties of Moclobemide (MCB) were investigated at glassy carbon electrode (GCE) and hanging mercury drop electrode (HMDE). Diffusion-adsorption behavior and some extra electrochemical parameters such as diffusion coefficient, number of transferred electrons and proton participated to its electrode mechanisms on both electrode and surface coverage coefficient were calculated from the results of cyclic voltammetry and square-wave voltammetry. Reversible catalytic hyd...
Controlling light inside a multi-mode fiber by wavefront shaping
Binici, Halil İbrahim; Yüce, Emre; Kocaman, Serdar; Department of Micro and Nanotechnology (2018)
Light is the primary tool used for collecting information from macroscopic and microscopic structures of matter. Micro-nano technology based materials like microcavities, waveguides, photonic crystals and fibers are used for confining light in space and the latter enable long distance information transfer. To increase the capacity of an information link, the core size of an optical fiber must be increased. Due to increased size of the fiber, the number of supported modes increases and becomes a multi-mode f...
Chebyshev Spectral Collocation Method for Natural Convection Flow of a Micropolar Nanofluid in the Presence of a Magnetic Field
Türk, Önder (2016-01-01)
The two-dimensional, laminar, unsteady natural convection flow of a micropolar nanofluid (Al2O3-water) in a square enclosure under the influence of a magnetic field, is solved numerically using the Chebyshev spectral collocation method (CSCM). The nanofluid is considered as Newtonian and incompressible, and the nanoparticles and water are assumed to be in thermal equilibrium. The governing equations in nondimensional form are given in terms of stream function, vorticity, micrototaion and temperature. The co...
Configuration of the Diels–Alder Adduct of Hexachlorocyclopentadiene withL-Menthyl Acrylate
Ülkü, D.; Tahir, M. N.; Demir, A. S.; Akhmedov, I.; Tanyeli, Cihangir (International Union of Crystallography (IUCr), 1997-7-15)
The structure of the title compound, endo-(2R)-(-)-L-menthyl 1,4,5,6,7,7-hexachloro-4-norbornene-2-carboxylate, consists of discrete C18H22CL6O2 molecules related by a twofold screw axis. The relative configuration was determined and the chirality at the unknown centres was assigned on the basis of the known chiral centres of L-menthene. Both the average Csp(2)-Cl, 1.689(5), and Csp(3)-Cl, 1.753(3) Angstrom, distances are a little shorter than the literature values. The six-membered ring of the L-menthyl gr...
Experimental measurements of interfacial strength at the nanoscale Nanoölçekteki arayüzeylerin kayma dayanimlarininin deneysel olarak ölçülmesi
Özerinç, Sezer (Journal of the Faculty of Engineering and Architecture of Gazi University, 2019-01-01)
Nanolayered metals are nanomaterials composed of alternating layers of two metals with layer thicknesses below 1 micron. Nanolayered metals are promising for engineering applications due to their superior properties such as high yield strength, thermal stability and radiation resistance. For the development of stronger nanolayers and for obtaining a better understanding of structure-proprety relationships of these materials, the interfacial strengths of the layers needs to be measured accurately and precise...
