S8. Interface Structure, Orientation, and Composition: Influence on Properties and Kinetics



Interface properties and kinetics can be controlled by structure, composition and orientation at atomistic, mesoscopic, and microscopic scales. Chemical adsorption, local structure, orientation, and microscopic shape (faceting) of interfaces have been observed to change with thermodynamic parameters (chemical potential, temperature, etc.), but the influence of these features on interface motion (grain growth, coarsening, sintering) and properties (grain boundary diffusion, electric and ionic or thermal conductivity, wetting) has not been fully correlated with the observed transitions. This symposium will examine both structure of interfaces over a variety of thermodynamic variables and influence of interface transitions on properties and kinetics.
