For the succesful and effective attendance of the course, a good knowledge of general chemistry is required and in particular good understanding of terms such as molecule, atoms, moles, Avogadro constant etc., as well as familiarity in calculations using those temrs. Ιn addition, it would be very helpful to the stutdents whether they could possess falimiarity with terms such chemical equilibrium and mass action law, thermally activated processes and Arrhenius kinetics, as well as the laws of Fick for diffusion and the meaning of the diffusion coefficient.
The basic understanding of the ideal and real structure of crystalline inorganic materials (metals, ceramics, alloys, solid solutions etc.) and their morphological characteristics of the microstructure (Materials Science and Technology I) so that the relation between structure and macroscopic properties or behaviour (Materials Science and Technology II) can be funadametnally understood.
Final goal is on one hand the ability of choice of the proper material for a certain application, on the other hand the ability to define interference pathways into a materials structure and microstructure in order to tailor its behaviour towards the desired direction (design).
