Contents:

General treatment of colloidal systems and their relevant interfaces. Thermodynamics of curved interfaces and adsorption at surfaces. Methods to determine surface tension. Recent developments in adhesion and wetting. Insight into (theories of) colloidal stability, charged interfaces and the electro-kinetic behavior of colloids.

Learning outcomes:

At the end of this course, the student:
- has a general knowledge of interface science;
- understands how interface energy describes the wetting behavior of surfaces;
- can use the Laplace equation to calculate the pressure drop over a curved interface;
- can use the Kelvin equation to determine the effect of interface curvature on vapor pressure and solubility;
- has insight in absorption phenomena at interfaces and can describe these according to adsorption isotherms;
- has understanding about the surface potential including descriptive models;
- can identify which factors influence the stability of colloidal systems and can make qualitative predictions.
