Thermoelectric effects in electrochemical systems
TLDR
In this article, the Dufour energy flux density and thermal diffusion were applied to electrolytic solutions and the electrode interface to clarify the quantitative description of heat generation at an interface and its relationship to the temperature dependence of the open-circuit potential of thermogalvanic cells.Abstract:
Fundamental multicomponent transport equations, including thermal diffusion and the Dufour energy flux density, are applied to electrolytic solutions and the electrode interface to clarify the quantitative description of heat generation at an interface and its relationship to the temperature dependence of the open-circuit potential of thermogalvanic cells.read more

The Maxwell-Stefan approach to mass transfer
Rajamani Krishna,J.A. Wesselingh +1 more
TL;DR: In this paper, the limitations of the Fick's law for describing diffusion are discussed and it is argued that the Maxwell-Stefan formulation provides the most general and convenient approach for describing mass transport which takes proper account of thermodynamic non-idealities and influence of external force fields.
