Thermophysical properties of ?-Pu2O3: A new potential model
(American Institute of Physics Inc., 2013)
?-Pu 2 O 3 is an important material among plutonium based materials in nuclear industry. Pure plutonium surfaces quickly oxidizes into ?-Pu 2 O 3 and PuO 2 which are in the form of layers one on another [1]. Here we have ...
Distribution of natural radionuclide concentrations in sediment samples in Didim and Izmir Bay (Aegean Sea-Turkey)
(Elsevier Sci Ltd, 2012)
Natural and artificial radionuclide pollutants of the marine environment have been recognized as a serious environmental concern. The natural radioactivity activity concentrations of Ra-226, U-238, Th-232 and K-40 were ...
Investigation of structural and electrical properties of Zirconium dioxide thin films deposited by reactive RF sputtering technique
(Taylor & Francis Ltd, 2016)
ZrO2 thin films with different thicknesses (400nm, 500nm, 600nm) were deposited by reactive RF magnetron sputtering technique, on n-type Silicon (100) substrate at 200 degrees C applying 125W power ratin`g. The micro ...
Microstructural properties of InGaN/GaN light-emitting diode structures with different In content grown by MOCVD
(Springer, 2014)
The structural and morphological properties of metal-organic chemical vapor deposition (MOCVD)-grown InGaN/GaN light-emitting diode (LED) structures with different In content have been studied by high-resolution X-ray ...
Graphene Oxide/Poly(3-hexylthiophene) Nanocomposite Thin-Film Phototransistor for Logic Circuit Applications
(Springer, 2018)
Graphene is a sheet-structured material that lacks a forbidden band, being a good candidate for use in radiofrequency applications. We have elaborated graphene-oxide-doped poly(3-hexylthiophene) nanocomposite to increase ...
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. ...
First - principles calculations on stability and mechanical properties of various ABO(3) and their alloys
(Elsevier Science Sa, 2018)
In this study, we perform first principle calculations based on density functional theory (DFT) to obtain the ground state structural, elastic and dielectric properties of various ABO(3) type ceramics and their {A(x)A'((1-x))}BO3 ...
Trace metal and radionuclide pollution in marine sediments of the Aegean Sea (Izmir Bay and Didim)
(Springer, 2013)
To determine radioactivity and trace metal levels, surface sediments were collected from two important areas (A degrees zmir Bay and Didim) in the Aegean Sea region of Turkey, and were analyzed for concentrations of Po-210, ...
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 and artificial radioactivity levels and hazards of soils in the Kucuk Menderes Basin, Turkey
(Springer, 2014)
In this study, natural and artificial radionuclide activity concentrations in surface soils of Kucuk Menderes Basin have been measured using gamma spectroscopy. The soil samples were collected from agricultural lands in ...
