Description du contenu de l'enseignement

Provide the students with the basics to understand:
  • surface phenomena
  • colloidal stabilization
  • surfactant behavior
  • techniques used to study surfaces and interfaces (in particular optical techniques)


Physical-chemistry of surfaces and interfaces
  • Description of interactions playing a role in interfacial phenomena
  • Van der Waals type interactions between macroscopic bodies
  • Electrostatic and steric colloidal stabilization
  • Basics of thermodynamics of surfaces and interfaces
  • Wetting (total and partial)
  • Homogeneous nucleation
Techniques to investigate surfaces
  • Reflection of light at a perfect interface (Fresnel's laws, evanescent waves)
  • Reflection of light by a thin film (matrix method)
  • Description of different optical techniques to investigate interfaces
  • Measurement of hydrodynamic thickness, differences between optical and hydrodynamic thickness.
  • Other techniques (streaming potential, AFM, XRay)

Compétences à acquérir

  • Acquisition of basics in the field of surfaces (developed and evaluated)
  • Capacity to read and understand articles in the field (developed and evaluated)
  • Capacity to select the appropriate technique to investigate the surfaces (developed and evaluated)
  • Develop critical thinking about data obtained by different techniques (developed)
  • Try to develop curiosity (by favoring the lecture of articles)
