  • Importance and function of interfaces in nature and technology with special emphasis on challenges in process engineering and mechanical engineering.
  • Introduction to the thermodynamics of interfaces with special emphasis on their application in technology.
  • Properties of different pairings of phases at interfaces (combinations of solid, liquid, gas) and their technical relevance.
  • Properties of different three-phase interfacial contacts (e.g. solid-liquid-gas or liquid-liquid-gas) as well as their technical relevance.
  • Experimental determination of interfacial properties (e.g. interfacial tension and wetting behavior) for different phase pairings (e.g. gas-liquid and solid-liquid).
  • Theoretical methods for determining interfaces properties: Density functional theory and molecular simulation

Competencies / intended learning achievements

  • Students are familiar with interfacial phenomena and processes relevant in technology, e.g. the wetting behavior, interfacial tension and adsorption.
  • Students have a general understanding of interfacial properties and their importance in technology and nature. Students can distinguish between properties of curved and planar interfaces as well as technical surfaces and (idealized) surfaces in a laboratory.
  • Students are able to describe and characterize experimental and theoretical methods for the determination and description of interface properties. They will be able to explain the basics of the methods and their limitations.
  • They will be able to select the appropriate experimental or theoretical method for a specific problem in interfacial thermodynamics.
  • The students are able to use modeling tools for selected problems and to evaluate the results with respect to the applied assumptions and simplifications.
