Tritium concentrations and consequent doses in bottled natural and mineral waters sold in Turkey and Azerbaijan
(Elsevier Ltd, 2021)
In this study, tritium levels in commercially sold bottled natural and mineral waters in Turkey and Azerbaijan were determined. Tritium measurements were performed using Liquid Scintillation Counter (PerkinElmer TriCarb ...
Dynamic magnetic properties of a mixed ferro-ferrimagnetic ternary alloy in the form of AB(p)C(1-p) with single-ion anisotropy
(Elsevier, 2021)
We investigate the dynamic magnetic properties of the AB(p)C(1-p) form mixed ferro-ferrimagnetic ternary alloy. For this purpose, the system was simulated by means of a Hamiltonian including single-ion anisotropy, A and B ...
Sequential forward mother wavelet selection method for mental workload assessment on N-back task using photoplethysmography signals
(Elsevier, 2021)
The increasing demands of a cognitive task require additional brain resources. This demand, known as mental workload, can lead to deteriorated task performance. Therefore, assessment of mental workload can provide a proper ...
Magnetic levitation force and trapped field properties of multiseeded YBCO with triangular arrangement of seeds
(Wiley, 2021)
Although there are studies in literature using different number of seeds with different arrangements, especially line and rectangular, it is seen that there is no detailed study handling the levitation force together with ...
Impact of in/ex situ annealing and reaction temperature on structural, optical and electrical properties of SnS thin films
(Elsevier, 2021)
In this work, SnS thin films were prepared by in situ and ex situ annealing process of precursor films deposited by RF (Radio Frequency) magnetron sputtering employing binary SnS target. In situ annealing treatment was ...
Processing CdS- and CdSe-containing window layers for CdTe solar cells
(Elsevier, 2021)
The influence of heat treatment steps on the characteristics of (CdS, CdSe) junction partners and on solar cell performance was studied. CdS films were obtained by chemical bath deposition, and CdSe layers were evaporated. ...
Hybrid transparent conductive electrode structure for solar cell application
(Elsevier, 2021)
This study draws on our experiences with graphene to perform a hybrid TCO structure composed of AZO and graphene. We first set out to enhance the electrical and optical properties of AZO to enable its use especially in the ...
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 ...
Phase transformation in Cu2SnS3 (CTS) thin films through pre-treatment in sulfur atmosphere
(Springer, 2021)
In this study, Cu2SnS3 (CTS) thin films prepared by a two-step sulfurization process were characterized. Cu and Sn metallic layers were first deposited on glass substrates by sputtering and then annealed in-situ while in ...
