Content, progress and pedagogy of the module

This course introduces students to the fundamental concepts and methodologies in colloid and interface science, with an emphasis on both theoretical understanding and practical applications. Key topics include:

• Types and classifications of colloids (e.g., macromolecules, clusters, emulsions)
• Surface and interfacial tension
• Wetting phenomena and contact angles
• Adsorption at interfaces
• Formation and behavior of micelles, foams, and bubbles
• Sol-gel processes and their relevance to materials science
• Electrostatic interactions, the electrical double layer, and colloidal stability
• Zeta potential and its measurement
• Advanced characterization techniques, including scattering methods (light, X-ray), electron microscopy, and surface analysis tools

The module is designed to provide a strong theoretical foundation while also preparing students to apply advanced characterization techniques that may be relevant to their semester project work. Emphasis is placed on how colloidal and interfacial phenomena influence the physical properties and functionality of materials in various engineering and biotechnological contexts.
