Identification of heavy metal origins related to chemical and morphological soil properties using several non-destructive X-ray analytical methods
(Kluwer Academic Publishers, 2013)
Soils are complex mixtures of organic, inorganic materials, and metal compounds from anthropogenic sources. In order to identify the pollution sources, their magnitude and development, several X-ray analytical methods were ...
Growth and characterization of CT(S,Se) thin films and Al/n-Si/p-CT(S,Se)/Mo heterojunction diode application employing a two-stage process
(Elsevier, 2023)
Cu2SnS3 (CTS), Cu2Sn(S,Se)3 (CTSSe), and Cu2SnSe3 (CTSe) thin films were deposited on n-type silicon wafer substrates using a two-stage process. This process involved drop-coating Cu-Sn precursors, which is different from ...
Human health risk assessment of heavy metals accumulation in different genders and tissues of whiting fish (Merlangius merlangus euxinus Nordmann, 1840) from Rize, Turkey
(Elsevier, 2024)
The contamination of fish resulting from marine pollution is a major concern, as it poses potential adverse effects on human health. Therefore, heavy metal concentrations (Cr, Fe, Ni, Cu, Zn, and Pb) in different genders ...
Polarized-beam high-energy EDXRF in geological samples
(0-Belirlenecek, 2013)
Certified reference materials (NIST 1645, BCR 143, IAEA 7, BCR 141, NIES-CRM-02, and IAEA 375) were used for determining the performance of a secondary target energy-dispersive X-ray fluorescence (EDXRF) spectrometer, ...
The effect of external electric field on mass attenuation coefficients of some semiconductor
(Taylor and Francis Inc., 2014)
In this study, we measured the mass attenuation coefficient of n-type GaAs, p-type GaAs, n-type Si and Au/n-Si/n+Si/Al samples with and without external electric field. Samples were set in perpendicular direction to the ...
Synthesis and fabrication of Mg-doped ZnO-based dye-synthesized solar cells
(Springer, 2014)
Undoped and 2, 4 and 6 at.% Mg-doped ZnO nanorods were successfully deposited on ZnO seeded fluorine tin oxide substrates by a simple chemical bath deposition technique to form a photoanode. It was seen that all the samples ...
Evaluation and mapping of radioactivity and radiological risks in sediments before the nuclear power plant in Türkiye
(Springer, 2024)
The main aim of this study was to investigated background levels of radioisotopes 137Cs (Cesium), 232Th (Thorium), 40K (Potassium), and 226Ra (Radium) in all samples taken from two important rivers of the Sinop province ...
Kinetic phase phenomena of model with the chemical formula ABpC1−p on honeycomb lattice
(Elsevier, 2024)
We investigate the ferromagnetic–ferrimagnetic ternary alloy model with the chemical formula ABpC1−p with mean-field theory based on Glauber-type stochastic dynamics, namely dynamic mean-field theory, on a honeycomb lattice ...
Fabrication of gold thin films on cooled glass substrates
(Springer, 2024)
In this article, gold (Au) thin films were fabricated on glass substrates under vacuum conditions (4.5 x 10(-6) Torr) within a temperature range of 100-300 K, incrementing in steps of 50 K. Analyses through Field Emission ...
Improving photovoltaic characteristics of CdS-based hybrid solar cells through Mn incorporation
(Elsevier, 2024)
CdS thin films, both with and without Mn-doping, were grown via chemical bath deposition on indium tin oxide-coated glass substrates for application in hybrid solar cells. X-ray diffraction analysis revealed that Mn doping ...
