Nanoparticles of Ni0.3Zn0.4Ca0.3Fe2O4 (NZCF) were successfully prepared by the facile wet chemical method coupled with sonochemical method. These nanoparticles embedded in a graphene oxide (GO) matrix (NZCFG). Rietveld analyses X-ray diffraction, transmission electron microscope, scanning and photoelectron spectroscopy carried out to extract different relevant information regarding structure, morphology, ionic state. A major improvement saturation magnetization is achieved due substitution...
We have studied the mixed network former effect on dynamics of lithium ions in borotellurite glasses wide composition and temperature ranges. The length scales ion dynamics, such as characteristic mean square displacement spatial extent sub-diffusive motion been determined from ac conductivity dielectric spectra, respectively, framework linear response theory. relative concentrations different structural units deconvolution FTIR spectra. A direct correlation between concentration BO4 has...
In this paper we have studied the correlation of microscopic length scales ion dynamics with network structure in lithium-iodide–doped lithium metaphosphate glasses. We obtained for dynamics, such as characteristic mean square displacement and spatial extent sub-diffusive motion ions. observed that ions to travel a smaller distance overcome nearest percolation barriers order perform long-range diffusion. The phosphate chain lengths shorten addition iodide also these glasses, between has been...
Ion dynamics in lithium bismuth borate conducting glasses have been reported wide composition and temperature ranges. The activation energy for the dc conduction has analysed using Anderson-Stuart model a correlation between conductivity doorway radius predicted. characteristic length scales ion dynamics, such as mean square displacement spatial extent of sub-diffusive motion ions determined from ac dielectric spectra, respectively. A direct connection network structural units established.

We have reported the effect of immobile ions on ion transport in conducting lithium phosphate glasses for different doping concentrations and glass modifier to former ratio. The composition dependence conductivity these has been compared with that silver glasses. obtained microscopic length scales, such as mean square displacement center charge mobile spatial extent localized motion from dielectric spectra. observed a direct correlation between scales dynamics structural units network.
We have studied the dynamics of silver ions in AgI-doped Ag2O-SeO2-MoO3 mixed former glasses wide frequency and temperature ranges. observed that ionic conductivity exhibits a glass network effect for low AgI content. The scaling spectra shows mechanism charge carrier is independent composition. obtained mobile Ag+ ion concentration from Nernst-Einstein relation, which found to be temperature, but slightly dependent on also characteristic mean square displacement mapping time domain. It...
