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 ...
Semi-conductive carbon from industrial tea waste biomass for a p-n junction
(Springer, 2024)
Some semiconducting carbonaceous material was developed from industrial tea waste biomass by catalytic pyrolysis and heteroatom doping; then, a p-n junction was realized on an n-type Si substrate. I-V characteristics of ...
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 ...
Selective radiation measurement for safety evaluation on base stations
(Gazi University, 2013)
In this paper, general information about unionized radiation, standards and measurement routines for wireless communication systems, electromagnetic fields and antenna structures are given. The safety of mobile phones has ...
Assessment of radiological levels at schools in trabzon, turkey
(Sage Publications, 2013)
In this study, a survey on environmental radioactivity in 16 high schools located in north eastern region of Turkey (the black sea region, province of Trabzon) was carried out. Indoor air radon (222Rn) concentrations were ...
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, ...
Determination of trace elements in ashes of milk samples by using XRF technique
(Chemical Publishing Co., 2013)
Energy dispersive X-ray fluorescence system has been used to determine the heavy metal ions present in cow's milk. Samples have been collected from farm and markets within the border of Kahramanmaras province, Turkey. An ...
Influences of ferromagnetic deflectors between layers of superconducting power transmission cables on transport current losses
(Springer International Publishing, 2014)
Alternating-current losses in two-layer power transmission cables constructed by type-II superconducting strips in the presence of ferromagnetic deflectors between the layers are numerically investigated. Each layer comprises ...
