Preparation and Characterization of Polypropylene/Serpentine Composites
Tan, Semra; Tincer, İsmail Teoman (Wiley, 2011-07-15)
Composites of serpentine and polypropylene (PP) were prepared by twin-screw extrusion. Serpentine was collected as rocks from the Ankara-Beynam region and ground into powder with an average particle size of about 3 mu m for composite production. Both as-received (rock) and powdered serpentine were characterized. A silane coupling agent (SCA), gamma-aminopropyl triethoxy silane, was used for the surface treatment of serpentine. Mechanical properties of the composites were measured in terms of impact strength...
Preparation and characterization of acrylic bone cements
Endoğan, Tuğba; Hasırcı, Nesrin; Department of Chemistry (2005)
Acrylic bone cements are used in dentistry and orthopedic surgery to fix prosthetic devices into the bone. Bone cements transfer and distribute the applied load and increase the load-carrying capacity of the prosthesis/cement/bone system with the help of mechanical bonding between the device and the bone. In spite of all their advantages, bone cements have several drawbacks such as insufficient mechanical properties, high exothermic polymerization temperature, release of monomer to the environmental tissue ...
Preparation and characterization of hydroxyapatite containing acrylic bone cements
Başgörenay, Burcu; Hasırcı, Nesrin; Department of Polymer Science and Technology (2004)
Acrylic bone cements are one of the most important biomaterials used in orthopaedic surgery and dental applications to fill the cavities or provide mechanical interlock between prosthesis and the bone. Their biocompatibility can be increased by addition of different materials into the formulation, such as hydroxyapatite. Besides all the advantages, bone cements have several drawbacks including tissue necrosis, chemical necrosis, shrinkage of the cement and aseptic loosening. Therefore painstaking research a...
Preparation and characterization of polymer coated superparamagnetic magnetite nanoparticle agglomerates
TURAL, Bilsen; Özkan, Necati; Volkan, Mürvet (2009-05-01)
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 tempera...
Preparation and Characterization of Neodymia Doped PVA/Zr-Ce Oxide Nanocrystalline Composites via Electrospinning Technique
Keskin, Selda; Uslu, Ibrahim; TUNÇ, TUNCAY; ÖZTÜRK, MUSTAFA; Aytimur, Arda (2011-01-01)
In this study, neodymia doped poly(vinyl) alcohol/zirconium-cerium acetate (PVA/Zr-Ce) nanofibers were prepared using the electrospinning technique, and then calcined at 800 degrees C for 2 hours. For this purpose, PVA/Zr-Ce polymer solutions doped with different concentrations of neodymia were prepared using electrospinning technique, and then calcined and sintered at 800 degrees C for 2 hours. The effect of neodymia doping was investigated in terms of solution properties, morphological changes and thermal...
