Types of interfaces, similarities and differences. Thermodynamics of interface. Gibbs’ concept of interfacial region. First law of thermodynamics; excess character of interfacial energy; Gibbs’ dividing plane. Interfacial enthalpy, heat capacities. Second law of thermodynamics; interfacial entropy; free surface energy (Helmholtz); free surface Gibbs energy. Gibbs-Helmholtz and Gibbs-Duhem equations. Gibbs adsorption isotherm; functional definition of the localization of Gibbs dividing plane, relative interfacial excess. Adsorption on different interfaces. Insoluble molecular films on liquid surface, surface pressure, compression/decompression isotherms. 2D phase transitions of molecular films. Potential difference at interfaces; types of potentials. Electrical double layer at interfaces - models, methods of investigations, consequences; electrokinetic effects. Transport in electrolytes - diffusion, migration, convection. Nernst-Planck equation, boundary conditions: membrane potential and diffusion potential. Electrode processes in heterogeneous systems. Current-voltage curves, determination of the type of electrode process and kinetic parameters. Applications of electrode processes.
