High pressure phase transition and elastic behavior of europium oxide
(National Institute of Optoelectronics, 2014)
We report the questionable high pressure structural and elastic characteristics of europium oxide (EuO) up to 50 GPa with shell model potential framework by geometry optimization calculations. We determined B1→B2 phase ...
Effect of annealing temperature on magnetic and mössbauer properties of ZnFe2O4 nanoparticles by sol-gel approach
(Springer New York LLC, 2018)
In this study, spinel ZnFe 2 O 4 nanoparticles (NPs) were synthesized by citrate sol-gel route using nickel nitrates, ferric nitrates and citric acid by annealing at 900, 1000, and 1100 ? C. We reported the structural and ...
Synthesis and structural and magnetic characterization of BaZn x Fe12−x O19 hexaferrite: hyperfine interactions
(Springer New York LLC, 2017)
To study the effect of Zn substitution on structural magnetic properties and hyperfine interactions of barium hexaferrite, BaFe12−x Zn x O19 (0.0≤x≤0.3) hexaferrites were synthesized via sol-gel auto-combustion technique. ...
Mössbauer analysis and cation distribution of Zn substituted BaFe12O19 hexaferrites
(Springer New York LLC, 2018)
Barium hexaferrite is a well-known hard magnetic material. Doping using nonmagnetic cation such as Zn2+ were found to enhance magnetization owing to preferential tetrahedral site (4 f 1) occupancy of the zinc. However, the ...
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 ...
Structural and magnetic properties of thermal- and deformation-induced martensite in an Fe-27%Ni-4%Mn-1%Zn alloy
(Springer New York LLC, 2018)
Deformation- and thermal-induced martensite properties were examined according to existing martensite morphology and magnetic properties for same prior austenite homogenization conditions in Fe-27%Ni-4%Mn-1%Zn alloy. ...
Magnetic and kinetical properties of Fe-27%Ni-4%Mn and Fe-27%Ni-4%Mn-2%Zn alloys investigated by VSM and DSC
(Springer New York LLC, 2018)
We report on the structural, thermal, and magnetic properties of thermally induced martensite in Fe-27%Ni-4%Mn and Fe-27%Ni-4%Mn-2%Zn alloys. Scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and ...
Martensitic transformation and magnetic properties of the CuAl, CuAlMn, and CuAlMnZn alloys
(Springer New York LLC, 2018)
In the present work, the effect of alloying elements on the phase transformation which are formed by cooling effect in CuAl, CuAlMn, and CuAlMnZn (wt%) alloys are investigated using scanning electron microscopy (SEM) and ...
Crystal structure of rac-3-hydroxy-2-(p-tolyl)-2,3,3a,4,7,7a-hexahydro-1H-4,7-methanoisoindol-1-one
(International Union of Crystallography, 2015)
In the title compound, C16H17NO2, the cyclohexene ring adopts a boat conformation, and the five-membered rings have envelope conformations with the bridging atom as the flap. Their mean planes are oriented at a dihedral ...
Phase transition and elasticity of gallium arsenide under pressure
(Universidade Federal de Sao Carlos, 2014)
Geometry optimization calculations were performed for some structural, elastic and mechanical properties of gallium arsenide (GaAs) under pressures up to 25 GPa. In contrast to previous works, a recent Stillinger-Weber ...
