Role of the local structure in superconductivity of LaO0.5F0.5BiS2-xSex system
(Iop Publishing Ltd, 2017)
We have studied the local structure of LaO0.5F0.5BiS2-xSex by Bi L-1-edge extended x-ray absorption fine structure (EXAFS). We find a significant effect of Se substitution on the local atomic correlations with a gradual ...
Viscous dissipation effects on entropy generation in heated vertical parallel-plate channels for mixed convection
(Inderscience Enterprises Ltd, 2017)
In this study, effect of viscous dissipation on entropy generation for fully developed incompressible laminar flow mixed convection in vertical parallel-plate channels with asymmetric and symmetric uniform heat fluxes was ...
Role of Mg doping in the structural, optical, and electrical characteristics of ZnO-based DSSCs
(2017)
ZnO- and Mg-doped ZnO samples are prepared by spray pyrolysis on conducting glass substrates to fabricate ZnO-based dye-sensitized solar cells (DSSCs). In uences of Mg-doping content on the power conversion efficiencies ...
Assessment of metal concentrations (Cu, Zn, and Pb) in seawater, sediment and biota samples in the coastal area of Eastern Black Sea, Turkey
(Pergamon-Elsevier Science Ltd, 2017)
This study investigated the contents of Cu, Zn and Pb in seawater, sediment, different shell sizes of mussel (Mytilus galloprovinciaIis) and sea snail (Rapana venosa) samples collected from four different provinces of the ...
Improvement in levitation force performance of bulk MgB2 superconductors through coronene powder adding
(Elsevier Science Sa, 2017)
The effect of coronene (C24H12) addition on the levitation force properties of MgB2 superconductor has been investigated for the first time in this study. the polycrystalline disk-shaped MgB2 + y wt % C24H12 samples (y = ...
Effects of Na doping on CdS thin films and n-CdS/p-Si solar cells via chemical bath deposition method
(Korean Assoc Crystal Growth, Inc, 2017)
Un-doped and Na doped CdS thin films were deposited by chemical bath deposition method. the effects of Na doping on structural, optical and electrical properties of CdS thin films and n-CdS/p-Si heterojunction were ...
The investigation of magnetic levitation performances of single grain YBCO at different temperatures
(Elsevier Science Sa, 2017)
The temperature dependence of the magnetic levitation force has been investigated for single-grain YBCO bulk sample, 20 mm in diameter with a thickness of 8 mm, fabricated by top-seeded melt growth (TSMG) method using Nd123 ...
Determination of radioactivity levels and heavy metal concentrations in seawater, sediment and anchovy (Engraulis encrasicolus) from the Black Sea in Rize, Turkey
(Pergamon-Elsevier Science Ltd, 2017)
Seawater, sediment and fish (anchovy) samples consumed in the Rize province of the Eastern Black Sea region of Turkey were collected from five different stations. the radioactivity levels (Ra-226, Th-232. K-40 and Cs-137) ...
Effect of the Hamiltonian parameters on the hysteresis properties of the kinetic mixed spin (1/2,1) Ising ferrimagnetic model on a hexagonal lattice
(Elsevier Science Bv, 2017)
The hysteresis properties of a kinetic mixed spin (1/2, 1) Ising ferrimagnetic system on a hexagonal lattice are studied by means of the dynamic mean field theory. in the present study, the effects of the nearest-neighbor ...
Enhancement in the optical and electrical properties of CdS thin films through Ga and K co-doping
(Elsevier Sci Ltd, 2017)
In the presented work, Ga-doped CdS and (Ga-K)-co-doped CdS thin films are grown on glass substrates at a temperature of 400 degrees C through spray pyrolysis. Influence of K-doping on structural, morphological, optical ...
