Learning objectives of this course include:
- Students will posses insight in important interfacial aspects including interfacial energy and surface potential and be able to relate this to interpreting interfacial phenomena or observations.
- Students will be able to explain and mathematically describe different interfacial phenomena, such as: wetting, colloidal stability.
- Students will be familiar with experimental techniques for measurement of various colloidal and interfacial properties (ex. zeta potential, streaming potential, contact angle, etc.) and interpretation/limitations of these measurements.
- Students will understand the applicability and limitations of various colloid-related theoretical frameworks, such as DLVO/XDLVO.
- Students will be able to critically evaluate scientific literature on interfacial phenomena.
Description of colloids, surfaces and interfaces. All kinds of interfaces between different phases are treated. Thermodynamic descriptions of these interfaces are deduced. Several techniques for characterizing interfaces are discussed. During contact hours, the contents of will be presented and discussed, and exercises will be made and discussed. For each topic, a case assignment will be offered. Topics include:
- Lifshitz-van der Waals Interactions
- Polar/Acid-Base Interactions
- Wetting and Contact Angles
- DLVO and XDLVO interaction
- Electrokinetic Phenomena
- Electrostatic and Polymeric Stabilization of Colloids
- Colloidal Phenomena (Marangoni-Effect, Ouzo effect, etc.)
