A study of ion aggregation and intermolecular interactions

Article Abstract:

The coupling of electroactive oxidized and reduced species as well as electroactive ion-electroinactive counterion coupling inside the redox polymer on steady state current-potential responses has been studied. The Ising model is used in deriving the diffusion-migration which is then utilized in analyzing the steady-state current potential responses and intermolecular interaction. Results show that the rate of charge transport is dependent on association of electroactive species with inactive counterions along with interaction between electron transfer active species.

Modeling of the electrified interface of liquid membrane ion-selective electrodes

Article Abstract:

Research was conducted to analyze a model system with a composition typical for neutral carrier ion-selective electrode membranes generally used in practice. Computer modeling of the interface between two immiscible electrolyte solutions demonstrate that non-Nernstian behavior of cation-sensitive ion-selective electrodes can take place by three molecular mechanisms. the theory uses a lattice-based self-consistent field model extended to include ion-carrier complexation using multistate mechanism.

Theory of electrified interfaces: a combined analysis using the density functional approach and Bethe approximation

Article Abstract:

The metal/electrolyte interface is analyzed by employing jellium model for metal surfaces and Bethe approximation for dipolar interactions. The total surface energy considering the metal-solvent interactions is then calculated using a one-parameter family of trial functions for the electronic density profile. A systematic analysis of the metal-solvent bond length and its dependence on electrode charge density is presented. The results are discussed.
