Lecturer(s) :

Hagfeldt Ulf Anders

Language:

English

Summary

Acquire an understanding of interfacial phenomena, micro-heterogeneous colloidal solution systems and dynamic electrochemistry.

Content

1. Thermodynamics of interfaces
Interfacial tension and surface thermodynamic functions, Laplace pressure, spreading and wetting, contact angle (Young-Dupré equation), capillary ascension, vapor pressure of curved interfaces (Kelvin equation).

 

2. Colloids/Micelles
Gibbs adsorption equation, solutions of amphiphile molecules (surfactants), hydrophobic effect, micelle formation, critical micellar concentration. Monomolecular Langmuir-Blodgett films.

 

3. Solid/gas and solid/solution adsorptions
Langmuir, Fowler-Guggenheim and BET isotherms. Adsorption of gases on porous solids, capillary condensation in mesoporous particles.

 

4. Electrokinetic phenomena
Zeta potential, electro-osmosis and electrophoresis, streaming and sedimentation potentials.

 

5. Interfaces
Stability of colloids according to the DLVO model. Membrane potential, Goldman's equation.

6. Dynamic electrochemistry
Redox potentials, Nernst equation, mass transport, chronoamperometry, voltammetry, Butler-Volmer equation, three-electrode measurements
