The enthalpy of the subsystem of silver ions in the intercalation compounds Ag
x
TiS2 has been calculated from the electrochemically measured thermodynamic functions of the silver subsystem. The ionic conductivity and the coupled chemical diffusion coefficients for silver in the intercalation compound have been measured. The activation energy for diffusion of silver ions is determined and the obtained value is interpreted from analyzing the concentration dependence of the enthalpy of the ionic subsystem. The conclusion has been drawn that the high diffusion mobility is associated with the competition between the covalent and elastic interactions, which decreases the activation energy for diffusion of ions.read more

Kinetics of reactions in interlayer space of titanium diselenide intercalated with iron
TL;DR: The hierarchy of diffusion mobilities of various defects in FexTiSe2 intercalation compound has been determined in this article, and it has been found that the largest mobility is inherent to intrinsic defects of the TiSe2 lattice, i.e., vacancies in Ti and Se sublattices.

On the Electrical Conductivity of Cuprous Sulfide: A Diffusion Theory
TL;DR: Theoretical expressions for the potential distributions for the process of tending to the limiting stationary state as well as for the stationary state were derived for the residual potential, a potential which remains after the current has been switched off and decays according as the initial homogeneity is recovered as discussed by the authors.

Elastic energy and staging in intercalation compounds
TL;DR: In this paper, a simple model for the elastic energy associated with the intercalation of a layered host lattice is presented, which accounts for the staging phenomena observed in many intercalations systems and is compared with Safran's theory of staging.
