Diffusion preserves the positivity of concentrations, therefore, multicomponent diffu- sion should be nonlinear if there exist non-diagonal terms. The vast variety of nonlinear multicom- ponent diffusion equations should be ordered and special tools are needed to provide the systematic construction of the nonlinear diffusion equations for multicomponent mixtures with significant in- teraction between components. We develop an approach to nonlinear multicomponent diffusion based on the idea of… Expand

On the Value Method of Determining a Dominant Mechanism of Nonlinear Multicomponent Diffusion
Abstract The work is devoted to the problem of analyzing the mechanisms of nonlinear multicomponent diffusion in complex systems. A new method is proposed for determining the stoichiometricExpand
Nonlinear diffusion in multicomponent liquid solutions.
Mutual diffusion in multicomponent liquids is studied and taking into account molecular complex formation allows one to explain the experimental dependence of diffusion coefficients on the composition (components concentration). Expand
Governing equations in non-isothermal diffusion
Abstract Generalizations of Fick's law for the diffusion flux are often considered in the literature by analogy with those for the heat flux. The paper reviews the balance equations for a fluidExpand
Manifestation of Onsager’s off-diagonal fluxes in diffusion of coadsorbed particles
According to Onsager's phenomenological theory, the diffusion fluxes of coadsorbed particles are expressed via the gradients of their chemical potentials and can contain the off-diagonal terms. InExpand
Quasisolitons in self-diffusive excitable systems, or Why asymmetric diffusivity obeys the Second Law
It is demonstrated that quasi-solitons can be robustly observed in excitable systems with excitable kinetics and with self-diffusion only, and a reduction procedure can be used for the search of complicated wave regimes in multi-component, stiff systems by studying simplified, soft systems. Expand

Three mean-field models for bimolecular reactions proceeding on planar supported catalysts

Diffusion and Transport of Molecules In Living Cells
This work has shown that for diffusion on catalyst surfaces in crystal lattices, porous media, phase-segregation, etc. a more general nonlinear approach is required. Expand


Multicomponent diffusion theory and its applications to polymer‐solvent systems
Recent publications by Zielinski and Hanley and by Alsoy and Duda have proposed relationships between self- and mutual-diffusion coefficients in multicomponent systems that can be derived fromExpand

We elaborate how holonomic constraints can be incorporated into the general equation for the nonequilibrium reversible-irreversible coupling (GENERIC) framework of nonequilibrium thermodynamics.Expand
Constraints in nonequilibrium thermodynamics: General framework and application to multicomponent diffusion.
As a consequence of its more elaborate and restrictive structure, GENERIC removes the ambiguities occurring in the classical thermodynamics of irreversible processes when one works with redundant variables. Expand

The purpose of this article is to explore what a rational framework might be if one were to analyse the Kirkendall effect from a dynamical perspective, and the extent to which such ideas may have relevance to diffusion in solids. Expand
