The textbook outlines general issues of the thermodynamics of surface phenomena at phase boundaries in systems with varying degrees of dispersion. The processes of adsorption on solid and liquid surfaces are considered, and the stability of dispersed systems is discussed. Separate chapters are devoted to colloidal solutions and basic concepts about nanomaterials.

The textbook is intended for students of higher educational institutions studying in the master's program "Materials Science of Nanomaterials and Electronic Components" in the direction of master's training "Technical Physics". It can also be used when teaching students in the areas of training “Materials Science and Technology of Materials”, “Metallurgy”, in advanced training systems, in institutions of additional professional education.

Recommended by the UMO for university polytechnic education as a teaching aid for university students studying in the master's program "Technical Physics".
