First discovery of middle tournaisian conodonts in the Griotte-type nodular pelagic limestones, Istanbul area, NW Turkey
Göncüoğlu, Mehmet Cemal; Goncuoglu, Y (2004-07-01)
The uppermost layers of the Ayineburnu member of the Buyukada Formation in the Istanbul-Gebze area are represented by Griotte-type pelagic nodular limestones. They yielded conodont elements (Bispathodus stabilis and Sipbonodella lobata) that can identify the interval from the upper part of the sandbergi Zone through the isosticba- Upper crenulata Zone - middle Tournaisian - Early Carboniferous. This is the first middle Tournaisian conodont record published from an autochthonous succession in the Istanbul Te...
First-principle investigation for the hydrogen storage properties of NaXH3 (X= Mn, Fe, Co) perovskite type hydrides
SÜRÜCÜ, GÖKHAN; CANDAN, ABDULLAH; Gencer, Ayşenur; IŞIK, MEHMET (Elsevier BV, 2019-11-15)
In the present study, NaXH3 (X = Mn, Fe, Co) perovskite type hydrides have been investigated by performing first-principles calculation. The results of the structural optimizations show that all these compounds have negative formation energy implying the thermodynamic stability and synthesisability. The mechanical stability of these compounds has been studied with the elastic constants. Moreover, the polycrystalline properties like bulk modulus, Poisson's ratio, etc. have been obtained using calculated elas...
First-Principles Investigation of NOx and SOx Adsorption on Anatase-Supported BaO and Pt Overlayers

We present a density functional theory investigation of the adsorption properties of NO and NO2 as well as SO2 and SO3 on BaO and Pt overlayers on anatase TiO2(001) surface. Mono layers, bilayers, and trilayers of BaO grow without strain-induced large scale reconstructions. While the bilayer and trilayer preserve, to a large extent, the NO2 adsorption characteristics of the clean BaO(100) surface, the effect of the support is evident in SO2 and SO3 adsorption energies, which are somewhat reduced with respec...

First-principles investigation of LaGaO3 and LaInO3 lanthanum perovskite oxides
Erkisi, Aytac; GÖKOĞLU, GÖKHAN; Sürücü, Gökhan; Ellialtioglu, Recai; Yildirim, Erdem Kamil (2016-01-01)
Among the class of ABO(3)-type perovskite oxides, LaMO3 (M=Ga and In) compounds are investigated in cubic (Pm-3m), tetragonal (P4mm), hexagonal (P-3m1), rhombohedral (R-3c) and orthorhombic (Pbnm) phases using generalised gradient approximation (GGA) within the density functional theory. On-site Coulomb interaction is also included in the calculations (GGA+U). After the determination of the stable phase, phase transition pressures have also been calculated. Then, their full structural, mechanical, electroni...
