Mössbauer studies and magnetic properties of cubic CuFe2O4 nanoparticles
(Springer New York LLC, 2019)
This study reports the preparation and characterization of nanocrystalline spinel powder of cubic copper ferrite nanoparticles (NPs) which have been fabricated via a cost-effective citrate sol–gel approach. The structural ...
Structural and temperature-dependent optical properties of thermally evaporated CdS thin films
(Elsevier Ltd, 2019)
In this work, structural and temperature dependent optical properties of thermally evaporated CdS thin films were investigated. X-ray diffraction, energy dispersive spectroscopy and Raman spectroscopy experiments were ...
Tracking of SPIONs in barley (Hordeum vulgare L.) plant organs during its growth
(Springer New York LLC, 2019)
Barley plants were grown in water solutions containing nutrient elements and superparamagnetic iron oxide nanoparticles (SPIONs), particularly the magnetite nanoparticles (Fe3O4; 15–20-nm particle size). No visible detection ...
Restricted rotation around the methylene bridge of 5-(2-p-(chlorophenyl)benzimidazole-1-yl)methyl-4-(o-substitutedphenyl)-2,4-dihydro-[1,2,4]-triazole-3-thiones as evidenced by NMR, X-RAY and DFT studies and the importance of low energy rotational conformers
(Elsevier B.V., 2019)
The aim of this study was to clarify the restricted rotation around the –CH2–N bond of the compounds, 5-(2-(p-chlorophenylbenzimidazol-1-yl-methyl)-4-(o-methylphenyl)-2,4-dihydro-[1,2,4]-triazole-3 thione [1], 4-(o-florophenyl)- ...
Synthesis, characterization, conformational equilibrium and intramolecular hydrogen bond analysis of Novel Azocalix[4]arenes including acryloyl moiety using DFT studies
(Elsevier B.V., 2019)
Azocalix[4]arenes were synthesized via diazo-coupling reaction with aniline in 1:1, 1:2, 1:3 and 1:4 molar ratio. Novel Azocalix[4]arenes having Acryloyl moiety were prepared esterification reaction with metallic sodium ...
Effect of heating rate on thermoluminescence characteristics of Y2O3 nanoparticles
(Elsevier B.V., 2019)
The present paper reports the results of heating rate dependencies of thermoluminescence (TL)peaks observed for Y 2 O 3 nanoparticles in the below room temperature region. TL glow curve presented six peaks around 62.5, ...
Temperature dependence of band gaps in sputtered SnSe thin films
(Elsevier Ltd, 2019)
Temperature-dependent transmission experiments were performed for tin selenide (SnSe) thin films deposited by rf magnetron sputtering method in between 10 and 300 K and in the wavelength region of 400–1000 nm. Transmission ...
Cu-Al-Mn shape memory alloy based Schottky diode formed on Si
(Elsevier B.V., 2019)
In this work, martensite was made over the wide temperature ranges and the two forms of martensite mor-phology in Cu85.41Al9.97Mn4.62shape memory alloy (SMA) were β′and γ′martensite phases. The SMA wascharacterized by the ...
Ca2+/Mg2+ co-substituted strontium nanohexaferrites: magnetic investigation and Mossbauer analysis
