Assessment of human health risk from heavy metals levels in water and tissues of two trout species (Oncorhynchus mykiss and Salmo coruhensis) from the Frtna and Guneysu Rivers in Turkey
(Taylor & Francis Inc, 2017)
Human health risks were evaluated from consumption of heavy metal contaminated fish from the Firtina and Guneysu Rivers in Rize. the study was aimed to assess heavy metal load in water and two fish species. the potential ...
Study of the hydrothermal crystallization process of barium titanate by means of X-ray mass attenuation coefficient measurements at an energy of 59.54 keV
(Elsevier Science Inc, 2017)
In this work, the X-ray mass attenuation coefficients of hydrothermally synthesized barium titanate (BaTiO3) samples were calculated with the purpose of determining the crystallization sequence of BaTiO3. Hydrothermally ...
Controllable growth and characterization of highly aligned ZnO nanocolumnar thin films
(Elsevier, 2017)
We investigated the effects of growth conditions during magnetron sputtering on the structural, morphological, and optical properties of nanostructured ZnO thin films. Undoped ZnO thin films are deposited onto p-type Si ...
Effect of heat treating metallic constituents on the properties of Cu2ZnSnSe4 thin films formed by a two-stage process
(Elsevier Science Sa, 2017)
In this study Cu2ZnSnSe4 (CZTSe) thin films were grown by a two-stage process that involved sputter deposition of a Cu/Sn/Zn/Cu metallic stack, annealing the stack at various temperatures for 30 min, evaporation of a Se ...
Physical properties of CdS:Ga thin films synthesized by spray pyrolysis technique
(Springer, 2017)
This paper reports the investigation of physical properties of CdS:Ga thin films grown for the first time by a simple spray pyrolysis method as a function of Ga-doping level from 0 to 8 at.%. X-ray diffraction (XRD), ...
A comparison of two methods used for determination of tritium concentration in urine samples by liquid scintillation counter
(Springer Singapore Pte Ltd, 2018)
Background Tritium (3H) emits low-energy beta particles with a maximum energy of 18.6 keV. Liquid scintillation counting technique (LSC) is mostly used for the detection and quantification of low-energy emitters like H-3. ...
Dynamic hysteresis loops of the spin-2 bilayer Ising model
(Elsevier Science Bv, 2018)
Based on the mean-field theory and Glauber-type stochastic dynamics, the dynamic hysteresis loops (DHLs) of the spin-2 Ising model are studied on the bilayer square lattice. the DHLs are given for different values of ...
Optical and electrical optimization of dysprosium-doped CdS thin films
(Springer, 2018)
As-grown and Dy-doped CdS thin films containing concentrations of 1, 2, 3, 4 and 5 at.% Dy atom were prepared via chemical spray route on glass substrates. the constructed thin films were searched through analyzing their ...
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 ...
An overview of the ecological half-life of the Cs-137 radioisotope and a determination of radioactivity levels in sediment samples after Chernobyl in the Eastern Black Sea, Turkey
(Elsevier Science Bv, 2018)
A study which determined the activity concentration of Cs-137 in sediments contaminated by effluents from the Chernobyl accident which had collected along the coast of the Eastern Black Sea region in Turkey was carried out ...
