The course for Ph.D. students is focussed on the phenomena occurring on phase boundaries, their modelling and evaluation of basic characteristics of disperse systems. The classification and stability of disperse systems is discussed and related to their thermodynamical, optical, rheological and electrical properties, and examples of applications. Systems with nanometer-scaled patterns and their applications for adsorbates studies, colloidal systems, are addressed in particular.

Outcomes for the Ph.D. students:

1. Knowledge of the methods of characterisation of disperse systems and heterogeneous materials and of relevant models and selected industrial applications,

2. to critically assess the predictive and correlative properties of the models,

3. description of disperse systems and microstructures with emphasis on the applicability on the own research tasks of the students,
