Selection

The selection is based on 1-165 credits.

Course Aim

The aim of the course is that the student, after completion of it, should be able to:

• define and explain basic surface and colloidal concepts such as surface energy, surface potential, coagulation, capillary condensation, viscosity, and hydrophobicity

• describe diffusion and light scattering properties of colloidal particles

• explain the association properties of surfactants, i.e., how they form aggregates in water

• discuss phenomena related to adsorption in interfaces between different phases such as air-water, solid-water, and solid-gas phases

• apply the DLVO theory and explain factors that influence colloidal stability, i.e., how to prevent or facilitate aggregation

• identify and categorize expressions within rheology and be able to describe factors that influence viscosity

• relate surface and colloid chemical theory to various applications in industrial processes such as mineral processing, food processing, etc.

• formulate mathematical solutions to simple surface and colloid chemical problems, linked to the phenomena covered in the theoretical parts of the course

Contents

The course deals with

• the colloidal state,

• kinetic and optical properties,

• adsorption equilibria at the interface between different phases,

• charged interfaces,

• colloidal stability, and

• emulsions and foams.

The theory is applied during laboratory and calculation exercises. For example, zeta potential measurement can provide information about the surface charge, and contact angle measurement can be considered as a method for assessing surface hydrophobicity.

Realization

Each course occasion´s language and form is stated and appear on the course page on Luleå University of Technology's website.

The teaching consists of lectures, exercise sessions, and laboratory exercises. Theory and practical exercises are weighed together to apply the theoretical contents in the laboratory work and exercises. The students are expected to actively take part in lectures as well as exercises. For an active dialog between student and the teacher, small exercises and discussions will be arranged as part of the theoretical lectures. This gives the teacher greater opportunities to ensure that students are absorbing the theoretical information and the possibility to correct if there are any misunderstandings. Exercises and laboratory assignments aim to give a more concrete understanding for the theory and its links to practical applications.

Examination

If there is a decision on special educational support, in accordance with the Guideline Student's rights and obligations at Luleå University of Technology, an adapted or alternative form of examination can be provided.

The course is examined as follows: approved laboratory reports, participation in exercise sessions, and an approved written examination are prerequisites for an approved course.

Both theory and calculation tasks are included in the examine order to challenge the student’s ability to deal with surface chemistry problems and answer theoretical questions analytically and contribute to a deeper understanding of the subject. Differentiated grades are applied. Grade scale: 3-4-5.
