By a News Reporter-Staff News Editor at Physics Week -- Research findings on Nanocrystals are discussed in a new report. According to news reporting originating from Istanbul, Turkey, by VerticalNews correspondents, research stated, "Nanocrystalline cobalt ferrites substituted with Zn with formula, Co1-x Zn (x) Fe2O4 (x=0.0-1.0) were prepared by the hydrothermal method. In this process, triethylene glycol was used both as a solvent and surfactant."
Our news editors obtained a quote from the research from Fatih University, "The ac conductivity measurements of the samples showed a temperature-dependency at lower frequencies and independency at higher frequencies, which indicates the ionic conductivity. The ac conductivity depends on the temperature. This conductivity can be fitted with the well-known power law model in higher frequency. The dc conductivity is assumed to obey the Arrhenius equation. The dielectric behavior in various temperatures ranges revealed frequency dependency in a reciprocal power law. The dissipation of energy stored within the nanoparticle was found to act upon the reciprocal power law of the frequency dependency."
According to the news editors, the research concluded: "Both the analysis of electrical conductivity and the dielectric permittivity functions suggest that the ionic and polymer segmental mobility could strongly be coupled in the nanoparticles."
