Effect of ultra-thin CdSexTe1−x interface layer on parameters of CdTe solar cells
(Elsevier, 2022)
Effects of an ultra-thin CdSexTe1-x junction interface layer on CdTe solar cell parameters were investigated employing a CdSexTe1-x/CdTe absorber structure. CdSexTe1-x thin films with varying composition were grown by ...
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, ...
Use of the cold substrate method for biomaterials: the dtructural and biological properties of the Ag layers deposited on Ti-6Al-4V
(Springer, 2020)
Silver nanofilms were vacuum-deposited on Ti-6Al-4V substrates at low (< 300 K) temperatures to improve their biocompatibility. After the surface of the Ti-6Al-4V samples was coated with Ag over the temperature range from ...
The comparison of levitation and lateral force of bulk and cut-pasted bulk GdBCO samples at different temperatures
(Elsevier Science Sa, 2020)
In this work, in the first time, we have investigated the levitation and lateral force properties of bulk and cut-pasted bulk GdBCO samples at different temperatures and different cooling heights (CH) to determine the ...

(Elsevier, 2020)
This study presents a new concept of segmented antineutrino detector based on hexagonal plastic scintillator bars for detecting antineutrinos from a nuclear reactor core. the choice of hexagonal scintillator bars is original ...
Cold substrate method to prepare plasmonic Ag nanoparticle: deposition, characterization, application in solar cell
(Springer Heidelberg, 2020)
In this study, the surface plasmon effects of the Ag nanoparticle were investigated depending on the substrate temperature and coating time. Deposition procedure for the Ag coating was the vacuum deposition at low substrate ...

(Springer Heidelberg, 2020)
Purpose Different kinds of sensors such as accelerometers and gyroscopes have been used for inferring, predicting, and monitoring human activities for various kinds of applications, including human-computer interaction, ...
Transparent and conductive CdS:Ca thin films for optoelectronic applications
(Springer Heidelberg, 2020)
This paper presents the structural, morphological, optical and electrical evolution of Ca-doped CdS thin films. Non-doped and Ca-doped CdS samples with various amounts of Ca atoms (from 0 to 10 at.% with an increasing step ...
Effects of silver doping on magnetic levitation performance of MgB2 superconductors
(Elsevier Sci Ltd, 2020)
MgB2 bulk samples with the silver contents of 0, 1.5, 3.0, 4.5, 6.0, 9.0 and 12.0 wt% were fabricated at 775 degrees C for 3 h in Ar atmosphere by solid-state reaction method. the structural and electromagnetic properties ...
