Improving the stability of solar cells using metal-organic frameworks
(Royal Soc Chemistry, 2016)
Although Cu2S-containing chalcogenide solar cells are appealing and cost-effective for photovoltaics (PVs), these materials suffer from rapid performance degradation as a result of the diffusion of copper ions into the CdS ...
A study of temperature dependent local atomic displacements in a Ba(Fe1-xCox)(2)As-2 superconductor
(Royal Soc Chemistry, 2016)
We have studied the local structure of a Ba(Fe1-xCox)(2)As-2 superconductor using temperature dependent extended X-ray absorption fine structure (EXAFS) measurements. Polarized EXAFS at the Fe K-edge on an optimally doped ...

(Ijrr-Iranian Journal Radiation Res, 2016)
Background: Turkey, especially the northern part of it, was one of the countries which were contaminated by the Chernobyl accident. Rize is a city located in the Northeastern district of Turkey which was heavily influenced ...
Elemental composiiıons of some cosmetic products marketed in Turkey
(Parlar Scientific Publications (P S P), 2016)
The aim of this study was to determine elemental composition of various cosmetic products marketed in Turkey by X-Ray Fluorescence Spectrometry (XRFS). These cosmetic products ranged from blush, eye shadow, lipstick, nail ...
Investigation of natural radioactivity and associated radiological hazards in ceramic sanitary ware products commercially sold in Turkey
(Taylor & Francis Ltd, 2019)
All ceramic products used in the construction of buildings contain natural radioisotopes at various rates. These radioisotopes are the main source of outdoor radiation to which people living in houses or workplaces are ...
Determination of natural radionuclides and some metal concentrations in human tooth samples in the Rize province, Turkey
(Taylor & Francis Ltd, 2019)
The main purpose of this study was to identify the concentrations of naturally occurring radionuclides (Ra-226, Th-232 and K-40) and some metals (Fe, Ni, Cu, Zn, Pb and Cd) in tooth samples collected from humans living in ...
Assessment of metal concentrations (Cu, Zn, and Pb) in seawater, sediment and biota samples in the coastal area of Eastern Black Sea, Turkey
(Pergamon-Elsevier Science Ltd, 2017)
This study investigated the contents of Cu, Zn and Pb in seawater, sediment, different shell sizes of mussel (Mytilus galloprovinciaIis) and sea snail (Rapana venosa) samples collected from four different provinces of the ...
Improvement in levitation force performance of bulk MgB2 superconductors through coronene powder adding
(Elsevier Science Sa, 2017)
The effect of coronene (C24H12) addition on the levitation force properties of MgB2 superconductor has been investigated for the first time in this study. the polycrystalline disk-shaped MgB2 + y wt % C24H12 samples (y = ...
Effects of Na doping on CdS thin films and n-CdS/p-Si solar cells via chemical bath deposition method
(Korean Assoc Crystal Growth, Inc, 2017)
Un-doped and Na doped CdS thin films were deposited by chemical bath deposition method. the effects of Na doping on structural, optical and electrical properties of CdS thin films and n-CdS/p-Si heterojunction were ...
The investigation of magnetic levitation performances of single grain YBCO at different temperatures
(Elsevier Science Sa, 2017)
The temperature dependence of the magnetic levitation force has been investigated for single-grain YBCO bulk sample, 20 mm in diameter with a thickness of 8 mm, fabricated by top-seeded melt growth (TSMG) method using Nd123 ...
