Colloidal dispersions are systems where one phase, having at least one dimension between 1 and 1000 nm, is dispersed in a second phase. Examples are particles dispersed in a liquid to form a suspension or liquid droplets dispersed in a second liquid, in which it is insoluble, to form an emulsion.
Colloidal dispersions are present in every-day life, from food systems to ceramics. The chemistry of colloidal dispersions covers many overlapping fields of science, such as physical chemistry, organic chemistry, physics and biology. It is therefore rare that solely colloidal dispersions are covered in academic course programs.
Who is this course intended for?
The course is relevant for industrialists, researchers and PhD students working with development and formulation of any colloidal system, be it paints, coatings, ceramics, food or pharmaceutical formulations.
What will this course give me?
This course provides a comprehensive introduction to the fundamental and practical aspects of colloid chemistry and colloidal dispersions.
