Learning outcomes

After successful completion of the course, students are able to independently analyze problems in the area of colloid and interface physics, and they will be able to transfer conceptual and theoretical concepts to unexpected and new problems in the area.

Colloid and interface chemistry and physics covers a broad and diverse domain – the colloidal domain of nano-to-micro structured materials -and is concerned with fundamental aspects of molecular ordering in hierarchically emerging systems, and with interaction forces and energies in these systems. Applications include examples from the bio-, natural- and life science domain as well as technology in medical and technical areas.

After successful completion of the course, students understand the fundamentals and modern experimental methods, theories and simulation approaches in the colloid and interface domain. This includes for instance inter and intramolecular interactions, surface and interface structures, self-organized structures (lipids, micelles, liposomes…) and dynamic and static surface phenomena (e.g. contact angles, wetting and dewetting or the Marangoni effect), as well as specific (key/lock type) or non-specific biologic interactions.
