Total impedance of the double layer in ethanol at high pressure
In this research we propose in analytical form the formula for full electrode polarization impedance measured at high pressures. The main point in this formula is: “electrode polarization does not dominate at sufficiently high frequencies”. Using this principle, we are able to fit the electrode polarization effects and extract static conductivity and dielectric permittivity of the sample from the fit in the low frequency region, both in solid and liquid forms near the melting temperature. Beside that, we obtain the temperature dependence of the double layer exponent and demonstrate this dependence does flatten in the solid form of ethanol in comparison to the liquid state.
期刊介绍:
Chemical Physics publishes experimental and theoretical papers on all aspects of chemical physics. In this journal, experiments are related to theory, and in turn theoretical papers are related to present or future experiments. Subjects covered include: spectroscopy and molecular structure, interacting systems, relaxation phenomena, biological systems, materials, fundamental problems in molecular reactivity, molecular quantum theory and statistical mechanics. Computational chemistry studies of routine character are not appropriate for this journal.
