First-principles study of coupled effect of ripplocations and S-vacancies in MoS2
(Amer Inst Physics, 2019)
Recent experiments have revealed ripplocations, atomic-scale ripplelike defects on samples of MoS2 flakes. We use quantum mechanical calculations based on density functional theory to study the effect of ripplocations on ...
Comparison of plastic antineutrino detector designs in the context of near field reactor monitoring
(Elsevier Science Bv, 2019)
We compare existing segmented plastic antineutrino detectors with our new geometrically improved design for antineutrino detection and light collection efficiency. the purpose of this study is to determine the most suitable ...
An analysis on the relation between the seed distance and vertical levitation force for the multi-seeded YBCO using the modified advanced frozen image (MAFI) and experimental methods
(Elsevier Science Sa, 2019)
The higher magnetic levitation force and related stiffness values are very important for Maglev and magnetic bearing applications. Also, larger superconducting surface area is needed for continuous and larger magnetic ...
Investigation of magnetic force properties between different PMGs and multi-seeded YBCO superconductors with different seed distances
(Elsevier, 2019)
The magnetic levitation force in vertical direction and guidance force in lateral direction should be increased for enhancing the loading capacity and stability of Maglev systems, respectively. in this study, we have ...
Investigating XRF parameters and valance electronic structure of the Co, Ni, and Cu spinel ferrites
(Elsevier Sci Ltd, 2019)
In the present study, K X-ray emission spectra of Cu, Ni, Co spinel ferrite (MFe2O4) alloys obtained with a HPGe detector by inducing 59.54 keV and 22.1 keV y gamma-rays emitted from 3 Ci Am-241 annular source and 40 mCi ...
Growth and characterization of Cu2SnS3 (CTS), Cu2SnSe3 (CTSe), and Cu2Sn(S,Se)(3) (CTSSe) thin films using dip-coated Cu-Sn precursor
(Springer, 2019)
Ternary compounds Cu2SnS3, Cu2SnSe3 and Cu2Sn(S,Se)(3) thin films used in thin film solar cell applications were prepared at the first time by such a two-stage process that includes dip-coating of Cu-Sn precursors as ...
Magnetic properties of the spin-5/2 Blume-Capel chain in a magnetic field
(Elsevier, 2019)
The magnetization plateaus and thermodynamic properties of the antiferromagnetic spin-5/2 chain system were studied by using Blume-Capel model. the system with crystal field interaction in the presence of an external ...
Effect of annealing temperature on K-shell X-ray fluorescence parameters of zinc oxide thin films prepared by the sol-gel method
(Taylor & Francis Inc, 2019)
Zinc oxide thin films were grown on a glass substrate by a sol-gel process using a spin-coating technique. the obtained thin films were annealed between 350 degrees C and 550 degrees C in 50 degrees C steps and were then ...
Radiation shielding properties of mortars with minerals and ores additives
(Elsevier Sci Ltd, 2019)
Incorporation of mineral and ores as fine aggregate additives was investigated for its effect on the neutron and gamma-ray shielding properties of cement mortar. Five mortar mixtures have been prepared with different ...
Natural radioactivity in ceramic tiles and associated radiological hazards
(Ijrr-Iranian Journal Radiation Res, 2019)
Background: the natural radioactivity levels in ceramic tiles produced in Turkey were determined and the related radiological hazards were assessed. Materials and Methods: the natural radioactivity levels (Ra-226, Th-232 ...
