Introduction:

Physicochemical Approach to Colloid- and Nanoscience is an introductory course on the basic principles of colloid science, which forms a bridge between molecules and macroscopic world. The colloidal interactions influence almost all technological process and have a major impact on our ability to understand biological processes. Miniaturization of technical devices, possibly down to molecular scale, is an important strategy for material- and energy saving technologies. Due to significant development of nanotechnology, especially the preparation, stabilization and application of nanoparticles, we have to face the renaissance of colloid science. It must perhaps be considered as rather specialized interdisciplinary field, but obviously based upon chemical and physicochemical disciplines with a good balance between descriptive and quantitative parts.

The methods that prepare of colloidal dispersions will be introduced. Furthermore, theories related to Gibbs free energy change in the process of homogeneous nucleationas well as smart nanoparticles and magnetic colloids will be introduced.

Chapter 3 Stability of colloid- and nanoparticles                       4 hours

Main interactions which affect the stability of colloid and nanopartical, such as - van der Waals, electrostatic repulsion, hydrophobic interaction will be introduced.

Chapter 4 Kinetics of coagulation and gelation                         4 hours

Mechanism of coagulation and gelation, coagulation kinetics, Fick laws of diffusion will be introduced.

Chapter 9 Gels                                                6 hours

Gels classified according to their gelation mechanism, structure, thermal stability, will ben introduced. Furthermore, gelation mechanisn of physical gels, such as colloidal aggregation, crystallization, helix formation, H-bond, Coulombic interactions, as well as gelation mechanism of chemical gels, crosslinking polymerization and crosslinking of macromolecules will be introduced.
