In order to produce magnetic microparticles (agglomerates), magnetite (Fe3O4) particles were synthesized using coprecipitation of FeSO4 center dot 7H(2)O and FeCl3 center dot 6H(2)O with the presence of poly (methacrylic acid) (PMAA) in aqueous solution.. Transmission electron microscopy (TEM), X-ray diffraction, and vibrating sample magnetometry (VSM) methods were used to characterize the PMAA coated superparamagnetic agglomerates. The influences of various processing parameters such as the process temperature, PMAA content, and the addition of surfactant on the agglomerate size and size distribution of produced magnetic microparticles were investigated. The particle size and size distribution characteristics, (the volume weighted mean size (1)[4,31, surface weighted mean size D[3,2], the geometric standard deviation, and span value) of the magnetic agglomerates were determined using the laser diffraction technique. The PMAA coated magnetic agglomerates with surface weighted mean sizes ranging from 1.5 to 3 mu m were produced successfully.

Preparation and characterization of magnetic nanoparticles Küçük, Burcu; Volkan, Mürvet; Department of Chemistry (2009) Magnetite (Fe3O4) and Maghemite (γ-Fe2O3) are well-known iron oxide phases among magnetic nanoparticles due to their magnetic properties, chemical stability, and nontoxicity. They have gained acceptance in several fields of application of nanomaterials such as magnetic recording systems, magnetic refrigeration, magneto-optical devices, magnetic resonance imaging, magnetic separation techniques and separation and purification of biological molecules. Recently, there is a growing interest in the synthesis of ...
Synthesis of zinc oxide nanoparticles by aqueous methods and effect of metal incorporation on the structural/functional properties of nanoparticles Altıntaş Yıldırım, Özlem; Durucan, Caner; Department of Metallurgical and Materials Engineering (2014) Zinc oxide (ZnO) nanostructures have attracted considerable attention in many electrical, optoelectronic and magnetic applications due to their unique properties originating form characteristic wide band gap and large exciton binding energy of ZnO. Electrical, optical and magnetic properties of ZnO nanostructures strongly depend on their size and morphology. Therefore, there has been a strong interest in the synthesis of ZnO nanostructures with well-controlled size and shape. These synthesis approaches shou...
Synthesis of BaHF Ceramics by Microwave Heating Emel, Erdal; Tulbez, Sımge; Dericioğlu, Arcan Fehmi (null; 2016-11-25) Barium hexaferrite (BaFe12O19, BaHF) is an important magnetic material due to its effective electromagnetic wave absorbing characteristics. The most convenient way of producing BaHF ceramics is mixed oxide method in which BaHF powders are synthesized from Fe2O3 and BaCO3 starting materials by the action of heat. The calcination process is typically conducted by conventional heating under ambient atmosphere. However, microwave heating can be ...
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 of gold nanowires with high aspect ratio and morphological purity Dertli, Elçin; Nalbant Esentürk, Emren; Ünalan, Hüsnü Emrah; Department of Micro and Nanotechnology (2012) Metal nanoparticles have unique optical, electrical, catalytic and mechanical properties, which lead them to various applications in nanotechnology. In particular, noble metal nanowires are attracting growing attention due to their potential applications such as in opto-electronic devices and transparent conductive contacts (TCCs). There are two general approaches to synthesize nanowires: template-assisted and solution phase methods. However, these synthesis approaches have various disadvantages. For exampl...
