In the present study, silver nanoparticles were produced by hydrazine hydrate and oleylamine/oleic acid systems in order to investigate the effects of reducing agents with different strengths on the reduction mechanism. Particle size and size distribution of silver particles produced by slow reducing system were studied in detail by using transmission electron microscopy (TEM), X-Ray Diffraction (XRD), photon correlation spectroscopy (PCS), and surface plasmon resonance spectroscopy (SPR). Finally, reduction mechanism by oleylamine and oleic acid system was clarified and particles with average diameter of 2.7 nm were produced. Nano-sized particles were then placed at the center of the polymer fibers by coaxial electrospinning and nanocable like structures were produced. SEM and TEM were used for the characterization of these cables.

Preparation of iron oxide nanoparticles by microwave synthesis and their characterization Acarbas, Ozge; Ozenbas, Macit (American Scientific Publishers, 2008-02-01) In this study production of fine particle Fe2O3 via microwave processing of Fe(NO3)(3)center dot nH(2)O followed by low temperature annealing was reported. XRD was used to characterize the structural properties of nanoparticles. Approximate particle sizes were between 3-13 nm according to Scherrer's equation. Single point BET measurement results also show that samples have large surface area and they are nanometer sized particles. TEM study was conducted to examine the structure of the nanoparticles. TEM fi...
Characterization of iron oxide thin films prepared by sol-gel processing Karakuscu, Aylin; Ozenbas, Macit (American Scientific Publishers, 2008-02-01) Iron oxide thin films were prepared by spin-coating a gel solution of iron(III) nitrate dissolved in 2-methoxyethanol and acetylacetone on glass and quartz substrates. The film thickness was adjusted by changing the spinning rate of the spin coater, Annealing was carried out between 300 degrees C to 600 degrees C to investigate the phases present in the films. Viscosity of the main solution was found as 0.0035 Pa (.) s by viscosity measurement. TGA/DTA analyses showed that heat treatment should be done betw...
Synthesis of aromatic poly(pyridinium salt)s and their electrochromic properties Keshtov, M. L.; UDUM, YASEMİN; Toppare, Levent Kamil; Kochurov, V. S.; Khokhlov, A. R. (Elsevier BV, 2013-05-15) Synthesis of a series of new conjugated electrochromic polymeric pyridinium salts containing main-chain triphenylamine and their electrochromic properties were demonstrated. All polymers exhibit intense UV absorptions at 336-338 nm in DMF and 340-343 nm in thin film form and fluorescence centered at 410-438 nm in DMF and 460-461 nm in thin film form. The electrochromic properties of the films were investigated by electrochemical and spectroelectrochemical methods. Reversible redox signals with stable electr...
Synthesis of conducting copolymers of thiophene capped poly(ethylene oxide) with pyrrole and thiophene Yildiz, Huseyin Bekir; Kiralp, Senem; Toppare, Levent Kamil; Yagci, Yusuf; Ito, Koichi (Elsevier BV, 2006-11-10) Thiophene capped poly(ethylene oxide) (PEO) was synthesized. Copolymerisations of PEO with pyrrole (Py) and thiophene (Th) were achieved in water-sodium dodecyl sulfate (SDS) and acetonitrile (AN)-tetrabutylammonium tetrafluoroborate (TBAFB) solvent electrolyte couples via constant potential electrolyses. Characterisations of the samples were performed by NMR, cyclic voltammetry (CV), FT-IR, scanning electron microscopy (SEM). Electrical conductivities were measured by the four-probe technique. PEO-co-PTh f...
Synthesis and characterization of a new soluble conducting polymer and its electrochromic device Varis, Serhat; Ak, Metin; Tanyeli, Cihangir; Akhmedov, Idris Mecidoglu; Toppare, Levent Kamil (Elsevier BV, 2006-12-01) A mixture of isomers 2,5-di(4-methyl-thiophen-2-yl)-1-(4-nitrophenyl)-1H-pyrrole, 2-(4-methyl-thiophen-2-yl)-5-(3-methyl-thiophen-2-yl)1-(4-nitrophenyl)-1H-pyrrole and 2,5-di(3-methyl-thiophen-2-yl)-1-(4-nitrophenyl)-1H-pyrrole (Me-SNS(NO2)) were synthesized. Resulting monomers were polymerized chemically, producing soluble polymers in common organic solvents. The average molecular weight has been determined by gel permeation chromatography (GPC) as Mn = 5.6 x 10(3) for the chemically synthesized polymer. T...
