Description
Prof. Sebastian Pawlus
The lecture will present the differences between stable and metastable states and explain what the amorphous phase is. In particular, it will present the properties of supercooled liquids as a large group of metastable systems from which amorphous glasses are formed. Ways of achieving this state and selected methods of testing its properties (e.g., dielectric spectroscopy, rheology) will be presented. Unique methods of testing the effect of high pressure during isothermal compression and isobaric cooling of supercooled systems, used at the Institute of Physics, will be presented. Examples of the practical use of materials in an amorphous state (medicines) will be presented. Selected examples will show how research methods used to study supercooled liquids are used to study other systems, including metal-organic hybrid materials
