ZnO thin films were prepared using zinc chloride, zinc acetate and zinc nitrate precursors by spray pyrolysis technique oil glass substrates at 550 degrees C. Structural and optical properties of ZnO films were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM) and optical transmittance spectra. Regardless of precursors, ZnO thin films are all in hexagonal crystallographic phase and have to (0 0 2) preferred orientation. SEM images show completely different surface morphologies for each precursor in ZnO thin films. ZnO rod was observed only for zinc chloride precursor. The optical measurements reveal that films have a low transmittance and a direct band gap approximately 3.30 eV, which is very close to band gap of intrinsic ZnO.

Investigation of effect of kaolin addition on combustion characteristic of olive residue Batır, Özge; Külah, Görkem; Selçuk, Nevin; Department of Chemical Engineering (2017) In this thesis study, effect of kaolin addition on combustion characteristic of olive residue was investigated by using thermogravimetric analyzer (TGA) combined with Fourier-transform infrared (FTIR) spectrometer in parallel with ash characteristics by X-Ray Fluorescence (XRF) and X-Ray Diffraction (XRD). The experiments were carried out by burning olive residue with 2%, 4% and 8% by wt. kaolin at 900˚C. Results reveal that addition of kaolin leads to decrease in rate of weight loss during char combustion ...
Investigation of silver-induced crystallization of germanium thin films fabricated on different substrates Kabacelik, Ismail; KULAKCI, MUSTAFA; Turan, Raşit (2015-06-01) Silver-induced crystallizations of amorphous germanium (alpha-Ge) thin films were fabricated through electron beam evaporation on crystalline silicon (c-Si) (100), aluminum-doped zinc oxide (AZO), and glass substrates at room temperature. The solid-phase crystallization (SPC) of alpha-Ge films was investigated for various post-annealing temperatures between 300 and 500 degrees C for 60 min. Two crystallization approaches were compared: SPC and metal-induced crystallization (MIC). The structural properties o...
The Effect of Ultrasonication on the Size and Morphology of Iron Oxide - Chitosan Nano and Microparticles Akin, Deniz; YAKAR, ARZU; Gündüz, Ufuk (2013-04-28) The aim of this study is to synthesize magnetic Fe3O4-chitosan nano and microparticles (Fe3O4-CPs) by suspension cross-linking and ionic gelation methods and investigate the effect of ultrasonication on the size, morphology and magnetic properties. The synthesized particles were characterized by transmission electron microscopy (TEM), dynamic light scattering (DLS) and vibrating sample magnetometry (VSM). The results showed that the ultrasonication decreased the mean particle diameter and enhanced magnetic ...
The characterization of polyaniline and polypyrrole composites by pyrolysis mass spectrometry Hacaloğlu, Jale; Kücukyavuz, Zühal (2009-09-05) hi this work, direct insertion probe pyrolysis mass spectrometry technique was applied to investigate the thermal and structural characteristics of electrochemically prepared polyaniline (PANI), polypyrrole (PPy), and their composites/copolymers synthesized either by electrochemical polymerization of pyrrole on PANI-coated electrode (PANI/PPy) or by coating PANI on PPy (PPy/PANI) in H(2)SO(4) solutions. It has been determined that the polymer first coated on the electrode degraded to a certain extent during...
Synthesis and characterization of nanosized calcium phosphates by flame spray pyrolysis, and their effect on osteogenic differentiation of stem cells Ataol, Sibel; Tezcaner, Ayşen; Duygulu, Ozgur; Keskin, Dilek; Machin, Nesrin E. (2015-02-14) The present study evaluates the synthesis of biocompatible osteoconductive and osteoinductive nano calcium phosphate (CaP) particles by industrially applied, aerosol-derived flame spray pyrolysis method for biomedical field. Calcium phosphate nanoparticles were produced in a range of calcium-to-phosphorus ratio, (1.20-2.19) in order to analyze the morphology and crystallinity changes, and to test the bioactivity of particles. The characterization results confirmed that nanometer-sized, spherical calcium pho...
