The present study focuses on the synthesis, microstructural and magnetic properties of ternary FeNiCo nanoparticles. Nanocrystalline ternary FeNiCo particles were synthesized via hydrogen reduction assisted ultrasonic spray pyrolysis method in single step. The effect of precursor concentration on the morphology and the size of particles was investigated. The syntheses were performed at 800 degrees C. Structure, morphology and magnetic properties of the as-prepared products were characterized through X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and vibrating sample magnetometer (VSM) studies. Scherer calculation revealed that crystallite size of the ternary particles ranged between 36 and 60 nm. SEM and TEM investigations showed that the particle size was strongly influenced by the precursor concentration and Fe, Ni, Co elemental composition of individual particles was homogeneous. Finally, the soft magnetic properties of the particles were observed to be a function of their size.

Preparation and thermal characterization of poly(2-vinylpyridine) copolymers coordinated to Cr nanoparticles Öztürk, Yurdagül; Kayran, Ceyhan; Hacaloğlu, Jale (2015-06-01) In this study, polystyrene-block-poly(2-vinylpyridine), PS-b-P2VP, polyisoprene-block-poly(2-vinylpyridne), PI-b-P2VP and poly(methyl metacrylate)-block-poly(2-vinylpyridine), PMMA-b-P2VP, coordinated to Cr metal were synthesized and characterized by Fourier transform infrared, transmission electron microscopy and direct pyrolysis mass spectrometry techniques. Both thermal degradation mechanism and thermal stability of P2VP blocks were affected by the coordination of Cr nanoparticles to nitrogen of pyridine...
Synthesis optimization and characterization of chitosan-coated iron oxide nanoparticles produced for biomedical applications Unsoy, Gozde; Yalcin, Serap; Khodadust, Rouhollah; GÜNDÜZ, GÜNGÖR; Gündüz, Ufuk (2012-11-01) The chitosan-coated magnetic nanoparticles (CS MNPs) were in situ synthesized by cross-linking method. In this method; during the adsorption of cationic chitosan molecules onto the surface of anionic magnetic nanoparticles (MNPs) with electrostatic interactions, tripolyphosphate (TPP) is added for ionic cross-linking of the chitosan molecules with each other. The characterization of synthesized nanoparticles was performed by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS/ESCA), Fourier trans...
Synthesis and characterization of polythiophene/montmorillonite and polythiophene/polypropylene composites Dülgerbaki, Çiğdem; Küçükyavuz, Zuhal; Department of Chemistry (2006) In this study, polythiophene(PTP)/montmorillonite(MMT) nanocomposites were synthesized by in situ intercalative polymerization and chemical oxidative polymerization. In in situ intercalative polymerization method, composites containing 90 and 95% MMT were prepared. In chemical oxidative polymerization method, a series of composites ranging from 1 to 15% by weight MMT were synthesized. Thermal and morphological properties of samples were investigated by Differential Scanning Calorimeter (DSC), Thermal Gravim...
Syntheses, spectroelectrochemical and electrochemical characterizations of naphthodithiophene containing polymers for solar cell applications Akbayrak, Merve; Önal, Ahmet Muhtar; Department of Chemistry (2016) This study consists of synthesis of alternating donor-acceptor type hybrid monomers based on various carbazole units as the electron rich donor group and thieno[3,4c]pyrrole-4,6-dione (TPD) or 2,5-dihydro-3,6-di-2-thienyl-pyrrolo[3,4-c]pyrrole-1,4dione (DPP) as the electron poor acceptor unit. The main goal of this research was not only to synthesize new low band gap polymers but also to shed more light on the substituent and linkage side effect of carbazole units on the optoelectronic properties of monomer...
Synthesis, structural characterization and chemistry of tribenzoheterotriquinane based molecular structures. Kepil, Dilay; Günbaş, Emrullah Görkem; Department of Chemistry (2020) The synthesis of heteroatom containing derivatives of triquinane structure by the Mascal group represents an important development in the field of fundamental organic chemistry. Some derivatives of hererotriquinane structures showed unusual reactivity and structure properties. For example, oxonium ions are known as fleeting intermediates in certain reaction mechanisms. However, oxatriquinane, the oxygen containing analogue of heterotriquinane family, shows extreme stability. It can be chromatographed and su...
