  • The aim of the course is to describe technical surface and colloid chemical phenomena at a molecular level.
  • Surface and colloid chemistry is a knowledge area with numerous applications within all areas of chemical and biotechnological engineering. For instance almost all foods, numerous drugs, biological systems, bacterial suspensions, many polymer materials, all ceramic materials, multiphase processes and most chemical-technical consumer products are dispersions or by other means colloidal.

    The course is based on surface-active components. Both synthetic and natural amphiphiles are treated. Different phases (micellar, liquid crystalline and microemlsions) as well as aggregates such as vesicles are studied.

    A central concept is interparticular interactions in relation to colloidal stability. The role of surface activity in controlling interactions through adsorption and non-adsorption is discussed in relation to technical functionality in systems like emulsions and foams. The role of surface activity for wetting, filtration, dewetting, and sintering is discussed. A generally important aspect is how the material properties of dispersed systems are influenced by colloidal interactions and surface phenomena’s.

    The exercise part of the course threat quantitative aspects of the theory as well as problem solving in colloid chemistry. The practicals are aimed to illustrate how different surface and colloidal system might be constructed and work. The practicals are reported in written form. The projects consist of an analysis of surface and colloidal aspects of manufacturing, formulation or application of a consumer product with relevance to the interest of the student. The projects are reported in written and oral form.
Knowledge and Understanding
  • For a passing grade the doctoral student must
  • show understanding of the basic principles of surface activity and the characteristics and functionality of surface active components in disperse systems.
    explain and qualitatively describe colloidal interactions between particles and based on these predict colloidal stability or instability.
    describe the relationships between macroscopic material properties and microscopic structures.
Competences and Skills
  • For a passing grade the doctoral student must
  • be able to quantitatively evaluate the structure, formulations and stability of colloidal systems.
    be able to demonstrate understanding of surface and colloid chemistry theory and based on that evaluate technical situations, propose experimental studies and suggest techincal solutions.
    be able to perform and evaluate experimental investigations of colloidal functionality in technical systems.
    describe and be able to discuss how basic colloidal principles determine the outcome of a technical process and/or the functionality of a consumer product in written and oral form.
Judgement and Approach
  • For a passing grade the doctoral student must
  • be able to evaluate the complexity of a production process in realtion to its function for the consumer and impact on the internal and external environment from given background information.
    be able to independently search for and critically examine and evaluate information in scientific papers dealing with colloidal systems.

  • Laboratory exercises
  • Exercises
  • Project
Examination Formats
  • Written exam
  • Written report
  • Written assignments
  • Seminars given by participants
  • Mandatory reports from the practicals (2), written assignment and mandatory seminar assignment with written and oral reporting. Written exam. Students who miss a mandatory assignment may have it replaced by another new assignment covering similar aspects and training the same abilities.

    The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
  • Failed, pass
