The course is online with a series of pre-recorded lectures, with periodic zoom "tutorials". We will address a broad range of surface and colloidal principles and see how these are applied, for example in cosmetics, recycling, detergency, food technology and pharmaceuticals. Some of the sustainability issues we face in this discipline and their solutions form a continuous theme. We will discuss the surface science of nature – how nature solves such challenges as water harvesting by beetles in the desert, how geckos stick to the ceiling and the lotus leaf effect.

Intended learning outcomes
After completing the course, a student should be able to:
- Explain aspects of surface, colloid and soft matter chemistry.
- Apply surface and colloid science on interfacial phenomena.
- Communicate and present surface and colloid science.
Literature and preparations
Equivalent knowledge to a bachelors degree, minor or major, in chemistry, chemical engineering, or material science. and English corresponding to English B/6.
Examination and completion
If the course is discontinued, students may request to be examined during the following two academic years.
- INL1 - Assignment, 2.0 credits, grading scale: P, F
- RAP1 - Report, 3.0 credits, grading scale: P, F
Based on recommendation from KTH’s coordinator for disabilities, the examiner will decide how to adapt an examination for students with documented disability.
The examiner may apply another examination format when re-examining individual students.
Opportunity to complete the requirements via supplementary examination
Opportunity to raise an approved grade via renewed examination
- All members of a group are responsible for the group's work.
- In any assessment, every student shall honestly disclose any help received and sources used.
- In an oral assessment, every student shall be able to present and answer questions about the entire assignment and solution.
