Seasonal variation of the concentrations of Cs-137 in sediment, sea water, and some organisms collected from Izmir Bay and Didim
(Taylor & Francis Ltd, 2014)
Cs-137 in the marine environment mainly originates from fallout of atmospheric nuclear weapon tests, accidental releases from nuclear facilities, and from the Chernobyl accident. After the latter accident, many studies ...
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 ...
Effects of high-temperature AIN buffer on the microstructure of AlGaN/GaN HEMTs
(Pleiades Publishing Inc, 2013)
Effects on AlGaN/GaN high-electron-mobility transistor structure of a high-temperature AlN buffer on sapphire substrate have been studied by high-resolution x-ray diffraction and atomic force microscopy techniques. The ...
Analytical solutions of conformable time, space, and time–space fractional KdV equations
(2018)
In this study, we consider the Korteweg–de Vries (KdV) equation for solitary waves in the domain ofconformable fractional calculus. By means of this fractional theory, we obtain exact solutions for time, space, andtime–space ...
Characterization of an AlN buffer layer and a thick-GaN layer grown on sapphire substrate by MOCVD
(Springer, 2011)
An AlN buffer layer and a thick-GaN layer for high-electron-mobility transistors (HEMTs) were grown on sapphire substrate by metal-organic chemical vapor deposition (MOCVD). The structural and morphological properties of ...
Modeling Superionic Behavior of Plutonium Dioxide
(Walter De Gruyter Gmbh, 2016)
The Bredig transition to the superionic phase indicated with the.-peak in C-p was highly expected for plutonium dioxide (PuO2) as other actinide dioxides. However, least-square fit and local smoothing techniques applied ...
Levels of Po-210 and Pb-210 in mussel and sediments in Candarli Gulf and the related dose assessment to the coastal population
(Pergamon-Elsevier Science Ltd, 2013)
Po-210 and Pb-210 in mussel (Mytilus galloprovincialis) and sediment samples collected at Candarli Gulf during the period of 2010-2012 are presented and discussed. The activity concentrations of Po-210 and Pb-210 were ...
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 ...
AFM induced self-assembling and self-healing mechanism of silicon oxide nanoparticle linear array domains templated on Moire superlattice patterns on HOPG
(Elsevier Science Bv, 2019)
Silicon oxide nanocluster suspensions were drop-cast on highly oriented pyrolytic graphite (HOPG) and investigated using ultra-high vacuum non-contact atomic force microscopy (AFM). The assembly of silicon oxide nanoparticle ...
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 ...
