| Language of Teaching / Examination: | English |
| Duration: | 1 semester |
| Frequency of Offer: | Every winter semester |
| Credits: | 6 |
| Learning Outcome: | After completing the module, students will be able to analyze and apply modern concepts, methods and theories of physical interfacial chemistry. Students will gain a sound understanding of the fundamentals of the thermodynamics of phase boundaries and interfacial processes, methods for determining interfacial tension, films, interfaces with amphiphilic molecules (surfactants and micelles), colloids and adsorption phenomena. Students will also learn the fundamentals and applications of physical methods for characterizing solid surfaces using microscopic and spectroscopic methods. The module should enable students to transfer and apply the acquired knowledge independently and across disciplines to problems of interfacial chemistry. They learn the methodology of structuring scientific questions and using the methods of physical chemistry to examine them qualitatively and quantitatively, while making critical preliminary assessments, considerations and quantitative estimates and evaluating scientific plausibility. Students also learn problem-solving strategies, the description and communicative discussion of physical-chemical issues in interfacial chemistry and acquire social skills such as communication, creativity and scientific discourse. |
| Contents: | Section 1: Thermodynamics of phase boundaries and interfacial processes Thermodynamic description of interfaces Phase boundaries between two pure phases, between two phases with several components and involving three phases: Interfacial tension, pressure difference of two phases on curved surfaces (Young/Laplace equation), vapor pressure of a liquid (Kelvin equation), nucleation and growth of phases, wetting phenomena (contact angle, Young equation, wetting transitions); measurement methods, examples from interfacial chemistry, including surfactants, micelles and colloids; adsorption phenomena and examples of interfaces with unique properties. Section 2: Spectroscopic and microscopic methods for the characterisation of solid surfaces: - Electron Spectroscopy (UPS, XPS, Augerelectron spectroscopy) - Ion Spectroscopic Techniques (SIMS, Laser-MS) - Surface Photon Spectroscopic Methods (linear/non-linear methods) - Electron-Stimulated Microanalysis Methods (Scanning electron microscopy) - Scanning Probe Microscopy (Atomic force microscopy, Scanning tunnelling microscopy) - Thin films / Optical coatings (Fabrication (PLD), Characterization, Application) |
