NKEK12006U CANCELLED: Surface Physical Chemistry
MSc Programme in Biochemistry
MSc Programme in Chemistry
MSc Programme in Nanoscience
Surface Physical Chemistry; The course is roughly covering the
following themes in this order:
1) Intermolecular forces and potentials.
2) Interactions involving polar and polarizable molecules.
3) Van der Waals and steric forces between molecules.
4) Van der Waals forces between particles and surfaces.
5) Electrostatic forces between surfaces in liquids (EDL).
6) Combining forces: DLVO, hydration, wetting.
The student will acquire basic knowledge about forces between molecules and between surfaces. The student will understand the basic concepts involved in the theory. This includes understanding of concepts such as Van der Waals forces, electrical double layer of dissolved ions (EDL) and DLVO (colloid stability) theory and its application to experimental systems
The student will be able to participate in scientific activities within surface forces (research, conferences, general scientific discussions, understanding papers on the subject, etc.).
After having passed the course, the student should be able to:
- account for types of classical interactions between various types of species including ions, polar molecules, polarizable molecules and understand the concept of potentials.
- account for the origin and basic concepts of Van der Waals and steric forces.
- account for Van der Waals forces between surfaces and particles, Hamaker constant and the geometric derivation of the equations.
- account for the dissociation constant, electrical double layer, Grahame equation, effect of divalent ions, the Debye length.
- account for the combined effect of Van der Waals and electrical double layer: DLVO.
Understand the limitations of the theories involved
See Absalon for a list of course literature
The course will use latest litterature on Surfaces forces.
- 7,5 ECTS
- Type of assessment
- Continuous assessmentContinuous evaluation, internal censorship, evaluation is given by the 7 step scale. The evaluation is based on 3 written 1 hour subtests that carry equal weight towards the final evaluation. The tests will be in the form of assignments that covers the material covered up to the point of the test.
- All aids allowed
- Marking scale
- 7-point grading scale
- Censorship form
- No external censorship
several internal examiners
If ten or fewer students have signed up for re-exam, the type of assessment will be changed to oral exam:
The student will prepare 15 minutes presentations on close to 10 subjects in the pensum. One subject will be chosen at random at the reexam. The student will give her/his presentation and will be asked questions for 15 minutes in pensum. If a student fail to do any of the 3 subtest and/or is attending less than 60% of the course, the student will be asked to do the reexamination test to pass.
Criteria for exam assesment
Criteria is defined by the set of skills listed in the "målbeskrivelse"
In order to obtain the grade 12 the student should convincingly and accurately demonstrate the knowledge, skills and competences described under Learning Outcome.
- Theory exercises
