Korunur, Murat
The energy-momentum localization problem, which was attemted by Einstein himself for thefirst time, has been continued to the present day. Recently, new prescription obtained bymodifying the torsion theory and these results shed light on the solution of the energymomentum localisation problem. Focusing this purpose, we consider a Locally RotationallySymmetric Bianchi Type-II model in the teleparallel framework and calculate the modifiedenergy and momentum density for the general case. We also obtain the energy andmomentum density for some special cases of the modified theory and compare our resultswith previous work in the literature.

İncele - MakaleAçık Erişim2019The effect of graphene oxide on the structural and electrical properties of yttrium ferrite based nanopowders
Aydin, Handan
In this study, Yttrium Ferrite based nano electroceramics were prepared bythe doping at various ratios of graphene oxide by the hydrothermal method.The obtained doped and undoped samples were characterized by XRD, SEM,FTIR, DTA, UV-VIS-NIR spectroscopy, temperature dependent electricalresistance changes and dielectric measurements. From the XRD results, it isobserved that the obtained samples are polycrystalline with an Orthorhombicstructure. The crystal parameters are changed with the doping of grapheneoxide. FTIR spectra indicate that the graphene oxide changes the peakintensities. This confirms the incorporation of the graphene oxide into theceramic structure. The doping of the graphene oxide changes the optical bandgaps of the samples. The dielectric constants of the samples are changed withthe graphene oxide. The DC electrical conductivity measurements confirm thesemiconducting behavior of the samples. The obtained results indicate thatthe electronic and nanostructure of the synthesized electroceramics can becontrolled by the doping of graphene oxide for electronic and energyapplications.

Korunur, Murat
Bu çalışmada, mutlak paralellizm olarak bilinen alternatif bir bakış açısıyla ünlü kütleçekim problemlerinden birini inceliyoruz. Bainchi-Type IX uzay-zamanın Taub çözümü ve mutlak paralellizmde Hamilton yaklaşımı tekniği göz önüne alındığında, bu duruma karşılık gelen açısal momentum, toplam enerji ve momentum dağılımları elde edilmektedir. Temel sonuçlarımızın diğer bir yazar tarafından literatürde yayınlanan sonuçlarla uyumlu olduğu görülmektedir

Bulut, Hasan; Baskonus, Haci Mehmet
In this paper, we apply the sine-Gordon expansion method which is one of the powerful methods to the generalized-Zakharov equation with complex structure. This algorithm yields new complex hyperbolic function solutions to the generalized-Zakharov equation with complex structure. Wolfram Mathematica 9 has been used throughout the paper for plotting two- and three-dimensional surface of travelling wave solutions obtained.
