Course is offered by the department of Chemistry and Chemical Engineering
...along with their contact details. If the course have external guest lecturers or such, give a brief description of their role and the company or similar they represent.
If needed, list administrative staff, along with their contact details.
Short description of the course purpose and content: can be copied from syllabus in Studieportalen. Additional information can be added.
List all mandatory literature, including descriptions of how to access the texts (e.g. Cremona, Chalmers Library, links).
Also list reference literature, further reading, and other non-mandatory texts.
Description of the course's learning activities; how they are implemented and how they are connected. This is the student's guide to navigating the course. Do not forget to give the student advice on how to learn as much as possible based on the pedagogy you have chosen. Often, you may need to emphasize concrete things like how often they should enter the learning space on the learning platform, how different issues are shared between supervisors, etc.
Provide a plan for
- laboratory work
Should contain a description of how the digital tools (Canvas and others) should be used and how they are organized, as well as how communication between teachers and students takes place (Canvas, e-mail, other).
Do not forget to describe any resources that students need to use, such as lab equipment, studios, workshops, physical or digital materials.
You should be clear how missed deadlines and revisions are handled.

Learning objectives and syllabus
- describe how surfactants, surface active polymers, and polar lipids self-aggregate in solution and at surfaces
- describe the environmental issues related to surfactants
- understand how a balance between attractive and repulsive interactions governs the stability of dispersed systems
- understand the role of surfactants as emulsifier, wetting agent, foaming agent, and active ingredient in detergents
- describe the difference in physicochemical behavior between a low molecular weight surfactant and a surface active polymer and relate these differences to practical uses
- understand how combinations of surfactants and of a surfactant and a polymer behave
- understand the fundamental differences between a microemulsion and an emulsion and describe advantages and disadvantages with both system
- describe how surfactant self-assembly can be taken advantage of for organic and bioorganic synthesis and for preparation of inorganic nanomaterials
- understand how formulations based on organic solvents may be replaced by surfactant-based formulations such as emulsions and microemulsions as a way to make more environmentally benign products

If the course is a joint course (Chalmers and Göteborgs Universitet) you should link to both syllabus (Chalmers and Göteborgs Universitet).
Description of how the examination – written examinations and other – is executed and assessed.
- what components are included, the purpose of these, and how they contribute to the learning objectives
- how compulsory and/or voluntary components contribute to the final grade
- grading limits and any other requirements for all forms of examination in order to pass the course (compulsory components)
- examination form, e.g. if the examination is conducted as a digital examination
- time and place of examination, both written exams and other exams such as project presentations
- aids permitted during examinations, as well as which markings, indexes and notes in aids are permitted
Do not forget to be extra clear with project assignments; what is the problem, what should be done, what is the expected result, and how should this result be reported. Details such as templates for project reports, what happens at missed deadlines etc. are extra important to include.
