COURSE DESCRIPTION

Course objectives

Students will expand basic knowledge of colloid chemistry obtained from lectures in Physical Chemistry. They will learn principles and applications of surface and colloid chemistry.

Course enrolment requirements and entry competences required for the course

 

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

Students will upon completion of the course
1) know the modern instrument methods of separation, purification and identification of colloids, 2) be able to interpret properties and effects of surfactants (micellar colloids), 3) be able to explain the kinetic phenomena of colloidal solutions, 4) understand the electrokinetic phenomena, 5) be able to explain the rheological properties of colloidal system.

Course content broken down in detail by weekly class schedule (syllabus)

Lectures
1st week: Introduction. Classification of colloidal systems. Aggregation of colloidal particles.
2nd week: Micelle formation. Properties and structure of micelles in aqueous and non-aqueous solutions.
3rd week: Purification and separation of colloids, ultrafiltration, reverse osmosis.
4th week: Dialysis, lyophilization, gel filtration.
5th week: Size and shape of colloidal particles. Experimental techniques for determining the size and shape of the colloidal particles.
6th week: Kinetic properties of the colloidal systems, sedimentation, diffusion, osmotic pressure.
7th week: Interface Phenomena: liquid-gas, liquid-liquid, solid-liquid interface.
8th week: Viscosity of colloidal systems.
9th week: Experimental techniques for determining the surface composition.
10th week: Rheology of colloidal systems.
11th week: Electrical double layer, electrophoresis.
12th week: Electrokinetic potential and electrical mobility, electrokinetic phenomena.
13th week: Coagulation and stability of colloids.
14th week: Gel, membrane, biological membrane.
15th week: Emulsions and microemulsions.
Laboratory exercises
1. Microemulsions, size of microemulsions aggregates and dynamic. 2. Surface tension. 3. Critical micelle concentration. 4. Standard Gibbs energies of micellization of surfactants in aqueous solutions at different electrolyte concentrations. 5. Microstucture and stability in surfactant free microemulsions.

Student responsibilities

Students are required to attend classes and actively participate in the teaching process. This will be recorded and evaluated in making a final assessment.

Screening student work (name the proportion of ECTS credits for eachactivity so that the total number of ECTS credits is equal to the ECTS value of the course):

Grading and evaluating student work in class and at the final exam

The course content is divided into two units that students take over
partial exams or joining final exam at the end of the semester. The exam
is considered passed if students achieve at least 60%. The final grade is
based on the evaluation of partial exams. Grades: <60% not satisfied;
60-69% successful (2) 70-79% good (3), 80-89% very good (4), 90-100%
excellent (5).

Quality assurance methods that ensure the acquisition of exit competences

Quality of the teaching and learning, monitored at the level of the (1) teachers, accepting suggestions of students and colleagues, and (2) faculty, conducting surveys of students on teaching quality.
