CHEM-E2121 - Surface Chemistry of Bio-based Materials D, Lecture, 3.9.2024-10.10.2024

Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.

LEARNING OUTCOMES

After completing the course, the students will be able to understand the theoretical background of surface and colloid chemistry, and apply that knowledge in bioproducts engineering. In particular, the students will be able to:

  • Understand how surface energy and roughness affect the wettability of surfaces.
  • Identify different methods to modify surface properties.
  • Understand the fundaments of key surface analysis techniques.
  • Interpret the role of surface active components in surface modification, as well as in emulsions and foams.
  • Discuss the advantages and disadvantages of nanoparticles.
  • Comprehend different surface forces and how they affect the stability of colloidal dispersions.
  • Explain how polymers adsorb on surfaces and how they affect the interactions between particles or surfaces.
