A study on microstructural characterization of the interface between apatite-wollastonite based glass ceramic and feldspathic dental porcelain
PEKKAN, Gürel; PEKKAN, KERİMAN; PARK, JONGEE; Öztürk, Abdullah (2016-12-01)
In this study, the contact area between the glass ceramic containing apatite [Ca-10(PO4)6(O,F-2)] and wollastonite [CaO center dot SiO2] crystals (A-W glass ceramic) and feldspathic dental porcelain was characterized using scanning electron microscope and energy dispersive spectroscopy. Alumina-added A W glass ceramics were prepared by sintering glass compacts in the MgO-CaO-SiO2-P2O5-Al2O3 system at 1100 degrees C. Commercially available dental porcelains for alumina frameworks were applied on the A-W glas...

A study on nanofiller effects of serpentine in polypropylene matrix
Tan, Semra; Tincer, İsmail Teoman (2012-04-15)
The nanocomposite materials were prepared using serpentine as filler and polypropylene (PP) as the matrix in the presence of maleic anhydride grafted polypropylene (PP-g-MA) compatibilizer. The melt intercalation was carried out following serpentine modification with a quaternary salt of cetyl-trimethyl-ammonium bromide. The structure of nanocomposites was shown by X-ray diffraction (XRD) and transmission electron microscopy (TEM) studies. Thermal analysis performed by differential scanning calorimetry (DSC...
A theoretical study of chemical doping and width effect on zigzag graphene nanoribbons
Pekoz, Rengin; Erkoç, Şakir (Elsevier BV, 2009-12-01)
The energetics and the electronic properties of nitrogen- and boron-doped graphene nanoribbons with zigzag edges have been investigated using density functional theory calculations. For the optimized geometry configurations, vibrational frequency analysis and wavefunction stability tests have been carried out. Different doping site optimizations for a model nanoribbon have been performed and formation energy values of these sites revealed that zigzag edgesite for both of the dopants were the most favorable ...
