Projektbeschreibung der*des Nominierenden

Dr. Tiziana Boffa Ballaran investigates the crystal structure response of minerals and other complex inorganic materials to changes in pressure, temperature and chemical composition and relates it to thermodynamic properties and phase changes. In her present project, she is going to focus on solid solutions of garnets and carbonates and investigate the local elastic strain field which arises when smaller atoms are replaced by larger atoms. These results can then be compared to thermodynamic mixing properties in general.
