Molecular structure and phase change properties of various polymer-doped liquid crystal
(Elsevier Science Bv, 2019)
In this study, the electro-optical and phase transition properties of 4-cyano-4'-n-pentylbiphenyl (5CB) liquid crystal doped by various polymers have been investigated. New liquid crystals were synthesized by doping 5CB ...
Natural radioactivity measurements and evaluation of radiological hazards in sediment of Aliaa Bay, zmir (Turkey)
(Springer Heidelberg, 2021)
The activity concentration of natural Ra-226, Th-232, and K-40 radionuclides was examined in some selected locations in Aliaga Bay of Izmir district, Turkey. Sediment samples from 30 locations were collected and analyzed ...
New predicted two-dimensional MXenes and their structural, electronic and lattice dynamical properties
(Pergamon-Elsevier Science Ltd, 2019)
MXenes, transition metal carbides and nitrides, are a bourgeoning class of two-dimensional (2D) materials due to their tunable electronic and magnetic structures, rich surface chemistry and thermal stability. Here, we ...
Dose rates and seasonal variations of U-238, Th-232, Ra-226 K-40 and Cs-137 radionuclides in soils along Thrace, Turkey
(Springer, 2014)
Concentrations of U-238, Th-232, Ra-226, K-40 and Cs-137 are measured in collected soil samples from various locations in the Thrace region of Turkey. The activity concentrations range from 12.82 to 101.75 Bq kg(-1) d.w. ...
Annual effective dose of naturally occurring radionuclides in soil and sediment
(Taylor & Francis Ltd, 2014)
In this study, the natural radioactivity level of soils and sediments due to the usage of fertilizers, particularly phosphate fertilizers, in agricultural lands of the Buyuk Menderes River Basin, Western Turkey, have been ...
A suggestion to radiological hazards characterization of Ra-226, Th-232, K-40 and Cs-137: spatial distribution modelling
(Elsevier Science Bv, 2018)
Spatial distribution modelling has been proposed to characterize the radiological hazards associated with concentration of natural Ra-226, Th-232, K-40 and artificial Cs-137 radionuclides in the nature. These elements have ...
Descriptive statistics and risk assessment for the control of seasonal pollutant effects of Po-210 and Pb-210 in coastal waters (Canakkale, Turkey)
(Springer, 2018)
Po-210 is absorbed into the human body by seafood intake. Especially, mollusks and mussels are known to have much higher Po-210 concentration than fish among various other types of seafood and are consumed in large quantities ...
Electrical characteristics of Au/n-GaAs structures with thin and thick SiO2 dielectric layer
(Pleiades Publishing Inc, 2011)
The aim of this study, to explain effects of the SiO2 insulator layer thickness on the electrical properties of Au/n-GaAs Shottky barrier diodes (SBDs). Thin (60 ) and thick (250 ) SiO2 insulator layers were deposited on ...
Tuning of electronic structure, magnetic phase, and transition temperature in two-dimensional Cr-based Janus MXenes
(Amer Physical Soc, 2021)
Two-dimensional (2D) transition metal carbides and nitrides, called as MXenes, displaying astonishing properties are emerged as a new class of 2D layered materials. In this study, we have studied the structural, electronic, ...
Structural, electrochemical and optical properties of hydrothermally synthesized transition metal oxide (Co3O4, NiO, CuO) nanoflowers
(Springer, 2020)
In this work, structural, electrochemical and optical properties of the flower-like Co3O4, NiO and CuO nanostructures were investigated. Co3O4, NiO and CuO nanoflowers were prepared using hydrothermal method. Fourier ...
