New distribution records of Bohemian Waxwing Bombycilla garrulus (Linnaeus, 1758) from Turkey
(Universitatea din Oradea, 2019)
The Bohemian Waxwing (Bombycilla garrulus Linnaeus, 1758) is a rare and high irregular migrant in Turkey. Most of records from the country have been taken in winter season. In this study, four winter and one spring ...
Effect of immobilization on the activity of catalase carried by poly(HEMA-GMA) cryogels
(Elsevier B.V., 2019)
Hydrogen peroxide is converted by catalase to molecular oxygen and water to remove oxidative stress. In this study, catalase immobilization was performed using poly(2-hydroxyethyl methacrylate-glycidyl methacrylate) ...
A kind of energy storage technology: Metal organic frameworks
(2012)
Abstract- For last fifteen years energy has been transferred by using electricity. As an energy carrier electricity has some disadvantages like its wire need for transportation and its being non-storable for large amounts. ...
Ca2+/Mg2+ co-substituted strontium nanohexaferrites: magnetic investigation and Mossbauer analysis
(Springer, 2019)
We report a comprehensive evaluation of the microstructures, magnetic, and hyperfine traits of Ca2+/Mg2+ co-substituted strontium nanohexaferrites (SHFs) of chemical compositions Sr1-2xCaxMgxFe12O19 (x <= 0.1). These SHFs ...
The Temperature Effect on Magnetic Properties of NiFe2O4 Nanoparticles
(Springer, 2018)
In this study, NiFe2O4 nanoparticles (NPs) were fabricated via auto citric acid sol-gel route at three different temperatures (900, 1000 and 1100 A degrees C). X-ray diffraction (XRD) and Fourier transform infrared were ...
Microstructural, optical, and magnetic properties of vanadium-substituted nickel spinel nanoferrites
(Springer New York LLC, 2019)
The current study investigates the impact of vanadium substitution on the structural, magnetic, and optical properties of NiFe2−xVxO4 (x ≤ 0.3) nanoparticles (NPs) produced by the cost-effective sol-gel route. The as-prepared ...
Tb3+ substituted strontium hexaferrites: Structural, magnetic and optical investigation and cation distribution
(Chinese Society of Rare Earths, 2019)
In this study, SrFe12−xTbxO19 (0.00 ≤ x ≤ 0.1) hexaferrites (HFs) were prepared successfully by citrate sol-gel approach. X-ray powder diffraction analyses affirm the hexagonal structure of products. Impurity phase starts ...
Tailored microstructures, optical and magnetic qualities of strontium hexaferrites: Consequence of Tm3+ and Tb3+ ions Co-substitution
(Elsevier Sci Ltd, 2019)
Terbium (Tb) and Thulium (Tm) co-doped strontium hexaferrites (SHFs), with composition SrFe12-2xTbxTmxO19 (0.00 <= x <= 0.04), were prepared via sol-gel auto-combustion method. The effect of Tb3+ and Tm3+ (as codopants) ...
Analysis of forward and reverse biased current-voltage characteristics of Al/Al2O3/n-Si Schottky diode with atomic layer deposited Al2O3 thin film interlayer
(Springer, 2019)
The dark current-voltage (I-V) characteristics of Al/Al2O3/n-Si Schottky diode are investigated in a wide temperature range of 260-360 K. The diode shows four orders of magnitude rectification. In forward and reverse bias ...
Determination of current transport characteristics in Au-Cu/CuO/n-Si Schottky diodes
(Elsevier, 2019)
In this study, the material properties of CuO thin films fabricated by sputtering technique and electrical properties of CuO/n-Si structure were reported. Temperature-dependent current-voltage (I-V) measurement was carried ...
