Effect of CdS and CdSe pre-treatment on interdiffusion with CdTe in CdS/CdTe and CdSe/CdTe heterostructures
(Elsevier, 2021)
High efficiency CdTe solar cell structure has the configuration of CdS/CdSe/CdTe. Depending on the deposition and post deposition techniques employed, this stack is often subjected to high temperatures, often in presence ...
Mn substitution effect on the local structure of La(Fe1-xMnx)AsO studied by temperature dependent x-ray absorption measurements
(IOP Publishing, 2021)
The local structure of La(Fe1-xMnx)AsO has been investigated using temperature dependent Fe K-edge extended x-ray absorption fine structure (EXAFS) measurements. The EXAFS data reveal distinct behavior of Fe-As and Fe-Fe ...
Bio-kinetics of cesium-137 in Mediterranean mussel (Mytilus galloprovincialis) and sea snail (Rapana venosa) via seawater exposure
(Elsevier, 2021)
Accumulation and depuration kinetics in the samples of mussel (Mytilus galloprovincialis L. 1758) and sea snail (Rapana venosa (Valenciennes, 1846)) exposed to Cs-137 radioisotope via seawater exposure were investigated ...
Acute copper accumulation in Mediterranean mussel and sea snail
(Taylor & Francis Inc., 2021)
In this study, the rate of copper accumulation in mussel (Mytilus galloprovincialis) and sea snail (Rapana venosa) organisms exposed to acutely different non-lethal copper concentrations was investigated for 5 days under ...
Dynamic magnetic features of a mixed ferro-ferrimagnetic ternary alloy in the form of ABpC1−p
(Springer Heidelberg, 2021)
In this work, we studied the dynamic magnetic features of a mixed ferro-ferrimagnetic ternary alloy in the form of AB(p)C(1-p). We also investigated the effect of Hamiltonian parameters on the system's dynamic magnetic ...
Assessing pollution levels and health effects of heavy metals in sediments around Cayeli copper mine area, Rize, Turkey
(Bellwether Publishing, Ltd., 2021)
Heavy metal concentrations of Mn, Cr, Fe, Ni, Cu, Zn, Cd and Pb in sediment samples collected from 12 stations in the Black Sea coast, Buyukdere and Sabuncular streams around Cayeli copper mine area in Rize, Turkey were ...
Beam dynamic studies at accelerator system of gun for a self-amplified spontaneous emission free electron laser project
(Elsevier, 2021)
One of the important factors in high radiation generation facilities is the production of a high quality electron beam. To do that, the requirements of an optical electron source, such as current, radiation emission, etc. ...
Evaluation of ecological risk, source, and spatial distribution of some heavy metals in marine sediments in the Middle and Eastern Black Sea region, Turkey
(Springer Heidelberg, 2021)
In the present study, the concentration levels of heavy metals such as Mn, Fe, Ni, Cu, Zn, Cr, and Pb in sediment samples collected from 16 sampling locations in the Middle and Eastern Black Sea regions, Turkey, were ...
On the 30th anniversary of the Chernobyl Nuclear Power Plant Accident, assessment of the activity concentrations and the radiological hazard parameters of soil samples collected from Rize province and districts
(Elsevier Ltd, 2021)
Uranium, thorium and potassium are the main terrestrial sources of radiation that are located at different levels in the soil depending on the geographical and geological conditions and contribute to increase of the natural ...
Determination of hypertension disease using chirp z-transform and statistical features of optimal band-pass filtered short-time photoplethysmography signals
(Iop Publishing Ltd, 2020)
Hypertension is the condition where the normal blood pressure is high. This situation is manifested by the high pressure of the blood in the vein towards the vessel wall. Hypertension mostly affects the brain, kidneys, ...
