327-6100-00LMaterials Colloquium0 creditsP. Novák, G. Habert, S. Huber, K. Maniura, further lecturers
AbstractThe Materials Colloquium is a platform for PhD students, postdoctoral researchers, group leaders, senior scientists, and professors to present their own and their group’s research to their colleagues. The apero following the colloquium has the purpose to stimulate discussions and to promote networking in a relaxed, more informal environment. The Colloquium is open to all who are interested.
ObjectiveLearn about recent research in the field of materials science.

AbstractElectrolytes: conductivity, transfer number, diffusion, migration, convection. Electrode/electrolyte interface, Nernst equation, potential vs. turnover. Kinetics, overpotential. Electrocatalysis. Porous electrodes, solid state electrochemistry, current density distribution. Electroanalytical techniques. Applications: electrolysis, galvanotechnics, batteries; electrosynthesis, sensors, corrosion.
ObjectiveTowards the end of the course the students will understand the basics of electrochemistry and will be able to describe and calculate electrochemistry-related matters in industrial processes and products.
ContentHistoric development and applications of electrochemistry. Electrochemical cells: electrodes, electrolyte, charge transfer, material flux, electrochemical conversion. Electrolytes: structure of solutions, conductivity, transfer number, solid and polymer electrolytes, transport processes in the electrolyte (diffusion, migration, convection, limiting current density). Cell voltage, electrode potential, potential series. Reversible electrode reactions: Nernst equation, potential vs. turnover. Electrode / electrolyte phase boundary: electrochemical double layer, exchange current density. Kinetics of electrochemical reactions: global and local current density, overpotential, Tafel equation, Butler / Volmer equation. Electrocatalysis. Porous electrodes, solid state electrochemistry, current density in the electrodes and in the electrolyte, electrochemical engineering. Electroanalytical methods: chronopotentiometry, cyclovoltammetry, electrochemical impedance measurements. Applications: electrolysis, galvanotechnology, batteries, ultracapacitors, fuel cells, electrosynthesis, electrochemical sensors, corrosion.
