TL;DR: In this article, the magnetocaloric properties of cobalt ferrite nanoparticles were investigated to evaluate the potential of these materials as magnetic refrigerants, and the magnetic entropy change (ΔSm) calculated indirectly from magnetization isotherms in the temperature region 170-320 K was found to be negative.
Abstract: The magnetocaloric properties of cobalt ferrite nanoparticles were investigated to evaluate the potential of these materials as magnetic refrigerants. Nanosized cobalt ferrites were synthesized by the method of sol–gel combustion. The nanoparticles were found to be spherical with an average crystallite size of 14 nm. The magnetic entropy change (ΔSm) calculated indirectly from magnetization isotherms in the temperature region 170–320 K was found to be negative, signifying an inverse magnetocaloric effect in the nanoparticles. The magnitudes of the ΔSm values were found to be larger when compared to the reported values in the literature for the corresponding ferrite materials in the nanoregime.

TL;DR: In this paper, the authors investigated the role of service experience in B2B services vis-a-vis service quality and found that service experience was found to influence both perceived utilitarian and hedonic value derived from service.

TL;DR: In this paper, the first six terms of the stress field were obtained for both opening mode and shear mode loading, and it was observed that the structure of the terms other than r?1/2 and r0 are influenced by nonhomogeneity.
Abstract: Stress field for stationary cracks, aligned along the gradient, in functionally graded materials is obtained through an asymptotic analysis coupled with Westergaard's stress function approach. The first six terms of the stress field are obtained for both opening mode and shear mode loading. It is observed that the structure of the terms other than r?1/2 and r0 are influenced by the nonhomogeneity. Using this stress field, contours of constant maximum shear stress are generated and the effect of nonhomogeneity on these contours is discussed. ©2002 ASME

TL;DR: In this paper, the frequency dependence of ac conductivity is analyzed by the power law σ(ω)ac = Bωn which is typical for charge transport by hopping or tunnelling processes.
Abstract: Mn1−xZnxFe2O4 nanoparticles (x = 0 to 1) were synthesized by the wet chemical co-precipitation technique. X-ray diffraction and transmission electron microscopy and high resolution transmission electron microscopy were effectively utilized to investigate the different structural parameters. The ac conductivity of nanosized Mn1−xZnxFe2O4 were investigated as a function of frequency, temperature and composition. The frequency dependence of ac conductivity is analysed by the power law σ(ω)ac = Bωn which is typical for charge transport by hopping or tunnelling processes. The temperature dependence of frequency exponent n was investigated to understand the conduction mechanism in different compositions. The conduction mechanisms are mainly based on polaron hopping conduction.
