  • The laboratory is active in the field of investigation of colloidal systems and applications of new colloids, with a focus on formation and characterization of dispersed systems, ranging in size from nanoparticles and nanocapsules through microparticles and microcapsules, up to large beads and powders.
  • In addition, the research group deals with formulation chemistry in collaboration with industry to develop stable multicomponent, dispersed systems such as cosmetic emulsions and gels, paints, ink jet inks, coatings and pesticides.
  • Advanced, graduate-level coursework is offered.

Research provided
