Synthesis of AlNiCo Core Shell Nanopowders by Hydrogen Plasma Reaction
Genç, Ayşe Merve; Akdeniz, Mahmut Vedat; Öztürk, Tayfur; Kalay, Yunus Eren (2016-12-02)
Magnetic core/shell nanostructures have been recently received much interest owing to their utmost potential in permanent magnetic applications. In the present work, AlNiCo permanent magnet powders were synthesized by ball milling and a core/shell nanostructure was obtained using RF induced plasma. The effects of particle size and nanoshell structure on the magnetic properties were investigated in details. The coercivity of AlNiCo powders was found to increase with decreasing particle size, exclusively nano...
Synthesis of silver nanoparticles by oleylamine-oleic acid reduction and its use in making nanocable by coaxial electrospinning
Çınar, Simge; MAVİŞ, BORA; Çolak, Üner (American Scientific Publishers, 2011-12-01)
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, reductio...
Synthesis of Liquid Crystal Templated Polymeric Microparticles Shaped by Microwells
Kocaman, Ceren; Akdeniz, Burak; Büküşoğlu, Emre (2018-08-30)
We aimed to develop a new method for the synthesis of liquid crystal templated microparticles. In this study, polydimetylsiloxane (PDMS) masks which have protrusions in micro dimensions were used to template polyvinylalcohol (PVA) microwells. The liquid crystal mixtures of a reactive mesogen (RM257) and a nonreactive liquid crystal (E7) were filled into PVA microwells. The solution was then photopolymerized using a UV light source. After polymerization, microparticles were collected by dissolving PVA ...
Synthesis of silver nanowires through polyol process
Coşkun, Şahin; Ünalan, Hüsnü Emrah; Department of Metallurgical and Materials Engineering (2012)
Nanotechnology enabled synthesis of various shapes and morphologies of conventional materials. Nanotubes, nanoparticles, quantum dots and nanowires are the new form of materials. Especially nanowires have gotten great attention due to their unique physical, chemical and optical properties. Superior properties of nanowires are based on their high surface area and two quantum confinement directions. Silver is one of the most conductive metals and it has the highest thermal conductivity. Due to excellent prope...
Synthesis of alpha-Fe2O3/TiO2 heterogeneous composites by the sol-gel process and their photocatalytic activity
Bouziani, Asmae; PARK, JONGEE; Öztürk, Abdullah (Elsevier BV, 2020-09-01)
alpha-Fe2O3/TiO2 heterogeneous composites were synthesized by the sol-gel process to increase the photocatalytic activity of TiO2. The structural, morphological, and optical characteristics of the composites were determined by X-ray diffraction, scanning electron microscope, and UV-vis diffuse reflectance spectroscopy. Results revealed that the incorporation of alpha-Fe2O3 to TiO2 widened the visible light absorption ability of TiO2. It was realized that the calcination temperature plays a crucial role in m...
