AC dielectric strength of synthetic ester-based Fe3O4, Al2O3 and SiO2 nanofluids — conformity with normal and weibull distributions

2019
This paper is aimed at studying the influence of conductive (Fe 3 O 4 ) and insulating (Al 2 O 3 and SiO 2 ) nanoparticles at various concentrations on the AC dielectric strength of MIDEL 7131 synthetic ester. The Normal and Weibull distribution functions are used to analyze the breakdown voltages with 1, 10, and 50% risk probabilities estimated. It is

Magnetic, magnetocaloric and magnetoresonance properties of (1-x)la0.7sr0.3mno3/xgeo2 (x=0, 0.15)

2019
© 2019 Trans Tech Publications, Switzerland. 0.85La0.7 Sr0.3 MnO3 /0.15GeO2 composite material and pure La0.7 Sr0.3 MnO3 were investigated by X-ray diffraction, scanning electron microscopy, magnetometry and electron spin resonance methods. It was observed that both samples demonstrate the ferromagnetic properties, while the absolute value of the ...

Yrast structures in the neutron-deficient ¹²⁷59Pr68 and ¹³¹61Pm70 nuclei

1998
The odd-proton nuclei 127Pr and 131Pm have been investigated using the 96Ru(35Cl,2p2n) and 96Ru(40Ca,αp)/96Ru(39K,2p2n) reactions, respectively, at beam energies of 164, 180, and 186 MeV. States belonging to the yrast bands of 127Pr and 131Pm, which are interpreted as being based upon the h11/2 [541]3/2- proton configuration, have been observed from ...

EPR of the V⁴⁺ion in single crystals of pyrovanadates β-Mg2V2O7, α-Zn2V2O7: Spin-hamiltonian parameters

2018
© Kazan Federal University. The angular variation of V4+electron paramagnetic resonance (EPR) line positions were recorded in single crystals of β-Mg2V2O7and α-Zn2V2O7at 120 K and 295 K in three mutually perpendicular planes in the temperature range from 120 to 295 K and at some intermediate temperatures.

Magnetic granulometry and Mössbauer spectroscopy of FemOn–SiO2 colloidal nanoparticles

2018
© 2018 Elsevier B.V. The colloidal nanoparticles FemOn–SiO2 have been obtained using the sol–gel method. Based on the data obtained with transmission electron microscopy and dynamic light scattering, a lognormal size distribution of nanoparticles with an average size of 20–30 nm have been constructed.
