Subject aims expressed by acquired skills and competences

- Explain what is the essence of the interfacial energy excess and how the phenomena related to it affect crystallization, phase transformations and fracture mechanics. - Describe the methods used to characterize microgeometry of solid surfaces. - Clarify the reason of the selective evaporation of components in mixed phases and its technological consequences. - Explain how solid surfaces can be modified in order to optimize their properties with emphasis on plasma technologies. - Interpretation of the phenomenon of epitaxy and the way it can be used to optimize joints of two materials. - Explain the catalytical effect of interfaces on chemical processes. - Deal with surface active substances and the way they influence properties of dispersion systems, nanostructured substances, emulsions, colloids and foams. - Describe the part a structured internal surface plays in modern adsorbents, zeolites and intercalation compounds.
