© 2019 Author(s).The vibrational and thermo-elastic properties of BaScO3 compound have been investigated using Density Functional Theory (DFT) with Vienna Ab initio Simulation Package (VASP). Perovskite materials could crystallize in five possible crystal structures: orthorhombic, tetragonal, rhombohedral, hexagonal, and cubic. Therefore, BaScO3 has been investigated for these five possible crystal structures and the most stable phase has been determined as the orthorhombic phase. Then, the vibrational properties have been calculated and dynamical stability of the most stable phase of BaScO3 has been determined. In addition, thermo-elastic properties have been studied in the temperature range between 0 to 1000 K and pressure range between 0 to 20 GPa. As we know up to date, this is the first investigation of the vibrational and thermo-elastic properties of BaScO3 compound that could direct the future studies.

The mechanical and electronic properties of spinel oxides VX2O4 (X = Mn and Fe) by first principle calculations
Ylldlz, Bugra; Erkişi, Aytaç; Sürücü, Gökhan (2019-11-25)
© 2019 Author(s).We have performed first-principles density functional theory calculations within generalized-gradient approximation to obtain the mechanical properties and the electronic behavior of Vanadium based Spinel Oxides VX2O4 (X=Mn and Fe) which conform Fm-3m space group with 225 space number and are promising good candidates for spintronic applications due to their half-metallic band gaps (Eg=1.71 eV for VFe2O4 and Eg = 0.53 eV for VMn2O4) in the plotted spin-polarized electronic band structure.

DFT study for the mechanical and electronic properties of Mg3BHx (x=l,4,7) compounds for hydrogen storage applications
Gencer, A.; Sürücü, Gökhan (2019-11-25)
© 2019 Author(s).The electronic devices such as cell phones, laptops etc. are a necessary part of our daily life that requires portable power sources. Hydrogen being the most abundant element on the Earth, is an excellent energy carrier with high energy capacity that enable to use hydrogen storage methods in portable power sources. In addition, hydrogen storage could be essential to store the energy obtained from the renewable energy sources. The solid state hydrogen storage is an encouraging method for hyd...
Manufacturing silk/epoxy composite laminates: Challenges and opportunities
Hamidi, Youssef K.; Yalcinkaya, M. Akif; Güloğlu, Görkem Eğemen; Pishvar, Maya; Amirkhosravi, Mehrad; Altan, M. Cengiz (2019-02-06)
© 2019 Author(s).Application of natural fibers in polymer composites has been gaining popularity in several industries pursuing environmentally friendly products. Among the natural fibers with proven potential applications, silk fibers have recently received considerable attention from researchers. Silk fibers provide higher mechanical properties compared to other commonly used natural fibers such as sisal, jute, and hemp. Silk may also exhibit comparable specific mechanical properties to glass fibers. Howe...
Final results on neutrino oscillation parameters from the OPERA experiment in the CNGS beam
Agafonova, N.; et. al. (American Physical Society (APS), 2019-09-06)
© 2019 authors. Published by the American Physical Society.The OPERA experiment has conclusively observed the appearance of tau neutrinos in the muon neutrino CNGS beam. Exploiting the OPERA detector capabilities, it was possible to isolate high purity samples of νe, νμ and ντ charged current weak neutrino interactions, as well as neutral current weak interactions. In this paper, the full dataset is used for the first time to test the three-flavor neutrino oscillation model and to derive constraints on the ...

Öztürk, Murat; Sevim, Umur Korkut; Altlntaş, Olcay; Ünal, Emin; Akgöl, Oguzhan; Karaaslan, Muharrem; Sabah, Cumali (2021-01-01)
© 2021 The Author(s). Published by Cambridge University Press in association with the European Microwave Association.In this paper, we present a linear to circular polarization converter integrated in a concrete structure to eliminate signal transmission problem originated from the concrete buildings in microwave regime. Two polarization converter samples and a control specimen made by traditional concrete are designed and their signal transmission responses are compared experimentally. Axial ratio values w...
