Characterization of lead glazed potteries from Smyrna (Izmir/Turkey) using multiple analytical techniques; Part II: Body
(Elsevier Sci LTD, 2014)Lead glazed pottery was one of the most important ceramic ware groups for the Late Hellenistic, Roman, Byzantine and Ottoman cultures in Anatolia. They were produced in different places in Anatolia such as Tarsus, Iznik, ... -
Characterization of lead glazed potteries from Smyrna (Izmir/Turkey) using multiple analytical techniques; Part I: Glaze and engobe
(Elsevier Sci LTD, 2014)Eighteen lead glazed potsherds from the Ayasuluk region (Smyrna) were characterized in order to have detailed knowledge of their production technology. Micro-Raman and scanning electron microscopy (SEM) with the combination ... -
The role of hydrothermal pathways in the evolution of the morphology of ZnO crystals
(Elsevier Sci LTD, 2016)Understanding growth mechanisms usually leads to the successful preparation of a targeted microstructure. However, the large number of parameters that influence the shape and the size of nanostructures often make it difficult ... -
Effect of bias voltage on tunneling mechanism in Co40Fe40B20/MgO/Co40Fe40B20 pseudo-spin valve
(Elsevier Science BV, 2015)Bias voltage dependence of tunneling mechanism has been systematically investigated in Co40Fe40B20 (2.1 nm)/MgO (2 nm)/Co40Fe40B20 (1.7 nm) pseudo-spin valve magnetic tunnel junction deposited using the combination of the ... -
Cytocompatibility property evaluation of gas pressure sintered SiAlON-SiC composites with L929 fibroblast cells and Saos-2 osteoblast-like cells
(Elsevier Science BV, 2012)Although the oxide ceramics have widely been investigated for their biocompatibility, non-oxide ceramics, such as SiAlON and SiC are yet to be explored in detail. Lack of understanding of the biocompatibility restricts the ... -
Micro-Raman spectroscopic analysis of inks and pigments in illuminated medieval old-Slavonic manuscripts
(Wiley-Blackwell, 2012)Micro-Raman spectroscopy was applied in characterisation of inks and pigments used in the text, illuminations and miniatures of two old-Slavonic manuscripts: Vrutok four gospels (13th14th centuries) and Benche four gospels ... -
Synthesis of Phosphorus Included Multiwalled Carbon Nanotubes by Pyrolysis of Sucrose
(American Chemical Society, 2013)Multiwalled carbon nanotubes (MWCNT) were synthesized by a pyrolysis route which involves a dehydration step using phosphoric acid. The resultants were found to be mostly containing amorphous carbon with scattered MWCNTs ... -
Wear behavior of solid SiAlON milling tools during high speed milling of Inconel 718
(Elsevier Science Sa, 2017)Machining of Inconel 718 is a challenging process because of high hot strength and hardness, high reactivity with the tool materials and low thermal conductivity of Inconel 718 alloy. Although SiAION ceramics in the form ... -
Structure, Microstructure and Magnetic Properties of CoxNi100-x Powders Synthesized by Hydrothermal Method
(Springer, 2017)Pure NiCo nanoparticles with different compositions were synthesized by hydrothermal route at 100 degrees C during 2 h. From x-ray diffraction analysis, we have shown that the structure varies from face-centered cubic (FCC) ... -
The effect of SnO2 on the improvement of mechanical properties of MgO-MgAl2O4 composites
(Elsevier Sci LTD, 2012)Incorporation of SnO2 into MgO-spinel (M-S) increased mechanical properties significantly. Relationships between the parameters improving mechanical properties and microstructural variables were examined. Basic parameters ... -
Black ceramic pigments for porcelain tile bodies produced with chromite ores and iron oxide waste
(Korean Assoc Crystal Growth, Inc, 2011)In this study, two different natural chromite ores and iron oxide waste from the steel rolling industry were used as less expensive alternative raw materials for the synthesis of black ceramic pigments to be used in porcelain ... -
Preparation, Characterization and Catalytic Properties of SBA-15-SO3H Supported Tungstophosphoric Acid for Esterification Reaction
(Polish Acad Sciences Inst Physics, 2017)SBA-15-SO3H supported tungstophosphoric acid (TPA, H3PW12O40) mesoporous materials were synthesized by impregnation of TPA into the hydrothermally synthesized SBA-15-SO3H and the catalytic performances were compared for ... -
Analytical transmission electron microscopy observations on the stability of TiCN in electrically conductive alpha-beta SiAlON/TiCN composites
(Elsevier Sci LTD, 2014)Coating of alpha-beta SiAlON granules with TiCN powder led to a continuous 3D electrically conductive network formation. Here, the stability of TiCN grains following gas pressure sintering (GPS) and its effect on the ... -
