Manganese ferrite (MnFe2O4) has been successfully synthesized by using coprecipitation methods with a various particles size of 13.1, 13.8, 16.2, 18.1, and 18.4 nm. Analysis of crystal structure properties which has been carried out by using XRD (X-Ray Diffraction) method revealed that all samples belong to cubic spinel structure. The measurement used computerized impedance spectroscopy system ...
Polycrystalline ceramics of bismuth layered structure of (Bi2O3)(BaxFe1-xO3) (0.2x0.8, x is in step of 0.2) have been prepared by conventional solid-state reaction method to study its modified dielectric and electrical properties. X-ray diffraction technique is used on the powdered samples for physical characterization and an average grain size of 16 – 21 nm was obtained. The XRD analysis rev...
In this paper, the dielectric constant has been evaluated for ices Ih, III, V, VI, and VII for several water models using two different methodologies. Using Monte Carlo simulations, with special moves to sample proton-disordered configurations, the dielectric constant has been rigorously evaluated. We also used an approximate route in which proton-disordered configurations satisfying the Bernal...
