Application of Classical Thermodynamics to Conductivity in Nonpolar Media: Experimental Confirmation

Autor: S. Gourdin-Bertin, Claire Chassagne

Publikováno v: The journal of physical chemistry. B. 122(3)

We previously proposed ( Gourdin-Bertin , S. and Chassagne , C. J. Chem. Phys. 2016 , 144 ( 24) ) a simple theoretical model to account for the evolution of conductivity with dielectric permittivity in nonpolar media. In this article, we validate the

The electric signal induced by an ultrasonic wave in aqueous solutions of charged species is measured and analyzed. A device is developed which measures the raw induced electric signal for small sample volumes (few milliliters) and without any preced

Application of classical thermodynamics to the conductivity in non-polar media

Autor: S. Gourdin-Bertin, Claire Chassagne

Publikováno v: Journal of Chemical Physics, 144(24)

Electrical conductivity in non-polar media is a subject which recently regained interest. If most of experiments and theoretical developments were done more than 50 years ago, new experiments and theories have been recently published. As the electric

In electrolyte solutions, an electric potential difference, called the Ionic Vibration Potential (IVP), related to the ionic vibration intensity, is generated by the application of an acoustic wave. Several theories based on a mechanical framework ha

In the framework of irreversible thermodynamics, we show that the sedimentation current in electrolyte solutions is mathematically equivalent to the low frequency limit of the ionic vibration current, appearing in the presence of an acoustic wave. Th

Publikováno v: The Journal of Chemical Physics. 142:194706

In this article, the relations for electroacoustic phenomena, such as sedimentation potential, sedimentation intensity, colloid vibration potential, colloid vibration intensity/current, or electric sonic amplitude, are given, on the basis of irrevers
