Information

Prüfungsstoff

content of the lectures

e.g.
- what type of colloidal systems exist?
- what are colloids?
- what are interfaces?
- significant forces between colloidal particles: how they can be calculated in approximation and exactly and how they can be measured?
- how to form emulsions and foams?
- physical properties required for stable foams and emulsions to form
- how to manipulate the wettability of surfaces?
- why surfactants are active at interfaces?
- how to choose type/class of surfactant to use in certain situations? specifically which would be good to form emulsions, as dispersants and good wetting agents? which would be good to destabilise emulsions?
- why are rheological properties important in many applications and how to alter them?
- what is adsorption/absorption? how to describe these phenomena?
- electrical properties of interfaces
- kinetic properties of particles
