Despite the significant progress made in the field of electrochromic polymers, the multichromic facility of current knowledge is restricted. Therefore, as previously proven, electrochemical copolymerization of 1-benzyl-2,5-di(thiophen-2-yl)-1H-pyrrole (SNBS) and 3,4-ethylenedioxythiophene (EDOT) was used as a strategy to achieve desired multichromic properties, where the resultant copolymer displayed distinct color changes between claret red, yellow, green, and blue colors with short switching times and high optical contrast. As an application, absorption/transmission type electrochromic device with indium. tin oxide (ITO)/copolymer/gel electrolyte PEDOT/ITO configuration was constructed, where copolymer and PEDOT functioned as the anodically and the cathodically coloring layers, respectively. Results implied the successive use of this copolymer in electrochromic device applications, since the device exhibited short switching times with a wide color variation upon applied potential.

Nanotribological properties of the h-BN/Au(111) interface: a DFT study Baksi, Merve; Toffoli, Daniele; Gülseren, Oğuz; Üstünel, Hande (American Chemical Society (ACS), 2019-11-21) Understanding the quantum-mechanical origins of friction forces has become increasingly important in the past decades with the advent of nanotechnology. At the nanometer scale, the universal Amontons-Coulomb laws cease to be valid, and each interface requires individual scrutiny. Because of the well-known lubricating properties of two-dimensional materials, a significant amount of research has been performed in an effort to understand interfaces they form with one another. However, the interfaces between th...
Ballistic design optimization of three-dimensional grains using genetic algorithms Yücel, Osman; Aksel, Mehmet Haluk; Department of Mechanical Engineering (2012) Within the scope of this thesis study, an optimization tool for the ballistic design of three-dimensional grains in solid propellant rocket motors is developed. The modeling of grain geometry and burnback analysis is performed analytically by using basic geometries like cylinder, cone, sphere, ellipsoid, prism and torus. For the internal ballistic analysis, a quasi-steady zero-dimensional flow solver is used. Genetic algorithms have been studied and implemented to the design process as an optimization algor...
Composite slabs with expanded metal used as metal decking Keyder, E; Tengirsenk, O (2000-06-02) The feasibility of the use of expanded metal as metal decking in reinforced concrete slabs was investigated experimentally. 8 specimens either flat or having different corrugation geometries were tested. Flat or corrugated geometry of the specimen, strong or weak axis of expanded metal were chosen to be the variables of the test program. It was observed that the material develops excellent bond:with concrete and cracking takes place at significantly high load levels. Finite element models were set up and no...
Thermal decomposition of polystyrene-b-poly(2-vinylpyridine) coordinated to co nanoparticles Elmaci, Ayşegül; Hacaloğlu, Jale; Kayran, Ceyhan; Sakellariou, Georgios; Hadjichristidis, Nikos (2009-11-01) Direct pyrolysis mass spectrometry analyses of polystyrene-block-poly(2-vinylpyridne), PS-b-P2VP, indicated that the thermal degradation of each component occurred independently through the decomposition pathways proposed for the corresponding homopolymers; depolymerization for PS and depolymerization and loss of protonated oligomers for P2VP by a more complex degradation mechanism. On the other hand, upon coordination to cobalt nanoparticles, thermal decomposition of the P2VP blocks was initiated by loss o...
Conducting polymer composites of polypyrrole and polyimide Selampinar, F; Akbulut, Ural; Toppare, Levent Kamil (1997-01-01) A conducting composite of polypyrrole with a polyimide as the insulating matrix polymer was prepared via electrochemical methods. The characterization of the composite was done by FTIR, SEM and TGA studies. Conductivity and solubility studies together with spectroscopic methods reveal that a chemical interaction between the two polymers exists.
