Alloying and phase transformation in CdS/CdSe bilayers annealed with or without CdCl2
(Elsevier Sci Ltd, 2019)The present paper studies the structural, compositional, morphological and optical properties of thin CdS/CdSe stacks annealed in an inert atmosphere or subjected to a CdCl2 treatment. the bilayer stacks were fabricated ... -
CZTS layers formed under sulfur-limited conditions at above atmospheric pressure
(Elsevier Sci Ltd, 2019)In this study CZTS thin films were grown by a two-stage process that involved sequential sputter deposition of metallic Cu, Zn, and Sn layers on Mo coated glass substrates followed by RTP annealing in a sulfur atmosphere ... -
Effects of silver doping on magnetic levitation performance of MgB2 superconductors
(Elsevier Sci Ltd, 2020)MgB2 bulk samples with the silver contents of 0, 1.5, 3.0, 4.5, 6.0, 9.0 and 12.0 wt% were fabricated at 775 degrees C for 3 h in Ar atmosphere by solid-state reaction method. the structural and electromagnetic properties ... -
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 ... -
Influence of pre-annealing Cu-Sn on the structural properties of CZTSe thin films grown by a two-stage process
(Elsevier Sci Ltd, 2018)In this study CZTSe thin film were synthesized by a two-stage process that included sequential sputter deposition of Cu and Sn layers forming a Cu/Sn structure, pre-annealing the Cu/Sn structure at 200-380 degrees C for ... -
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 ... -

OXA- and GES-type beta-lactamases predominate in extensively drug-resistant Acinetobacter baumannii isolates from a Turkish University Hospital
(Elsevier Sci Ltd, 2014)We determined the antibiotic susceptibility and genetic mechanisms of resistance in clinical strains of Acinetobacter baumannii from Istanbul, Turkey. A total of 101 clinical strains were collected between November 2011 ... -
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 ... -
The size effect on the magnetic levitation force of MgB2 bulk superconductors
(Elsevier Sci Ltd, 2016)In this study, the size effect on the magnetic levitation performance of disk-shaped MgB2 bulk superconductors and permanent magnets was investigated. MgB2 samples with varying diameters of 13 mm, 15 mm and 18 mm, each of ... -
Zirconium-based highly porous metal-organic framework (MOF-545) as an efficient adsorbent for vortex assisted-solid phase extraction of lead from cereal, beverage and water samples
(Elsevier Sci Ltd, 2017)In this study, zirconium-based highly porous metal-organic framework, MOF-545, was synthesized and characterized. the surface area of MOF-545 was found to be 2192 m(2)/g. This adsorbent was used for the first time as an ...
