Information

Ziele, Inhalte und Methode der Lehrveranstaltung

Whether you look at the OLED display of your smartphone, soap bubbles during showering, or your milk for breakfast, soft matter interfaces are ubiquitous. This course gives an introduction to the physical principles to understand the structure and dynamics of soft condensed matter adjacent to solid, liquid, and vapor interfaces.
In particular, we aim for the links connecting intermolecular forces with molecular scale structure, dynamics, and physical materials properties. The course further introduces the experimental techniques required to study soft matter interfaces on the relevant time and length scales. Focus is set to scattering and spectroscopic techniques, providing complementary information.
The course will enable you to understand numerous physical phenomena surrounding us in everyday live while also providing you with the basic knowledge for improving the performance of modern soft materials for specific applications. Examples help to develop a deeper understanding and to explore links to other branches of physics.

Topics:
Thermodynamics of interfaces
Surface tension
Interface induced phase transitions
Adsorption and wetting
Charged interfaces and Helmholtz double layer
Surfactants and Emulsions
Interfacial freezing and premelting
Liquids in nanoporous materials
Self-organization of soft matter thin films
X-ray and neutron scattering
Reflectometry
X-ray spectroscopy

Art der Leistungskontrolle und erlaubte Hilfsmittel

Successful and regular active participation in exercises.
Oral exam at the end of the semester.
Due to Covid-19, the oral exam will held as online exam.

Mindestanforderungen und Beurteilungsmaßstab

After each lecture, there will be an exercise sheet to recapitulate the knowledge and reach in-depth understanding. Over the semester, students should have prepared solutions for at least 50% of the exercises and present their work at least 4 times orally at the blackboard.

Aim of the lectures is to obtain an overview over the current research on the molecular scale structure and dynamics of soft matter near interfaces. The exam will test the knowledge and understanding of the physical models and mechanisms as well as the relevant experimental techniques. Students will be asked to apply their knowledge to related problems and explain fundamental concepts and equations.
1. Excellent knowledge, can explain and apply concepts and equations: 1 (SEHR GUT)
2. Good knowledge, can explain concepts and equations: 2 (GUT)
3. Good knowledge, can understand concepts and equations: 3 (BEFRIEDIGEND)
4. Basic knowledge of concepts, can understand equations: 4 (GENUEGEND)
5. Else: 5 (NICHT GENUEGEND)

---------------------------------------------------

Final grad calculation:

25% written exercises
25% oral contribution incl. presentation
50% oral exam

Prüfungsstoff

Unless explicitly stated otherwise, all content covered in the lecture will be relevant for the exam. Slides will be provided online. Taking notes during the classes is recommended.
