Welcome to the second of two lecture series in Brescia 7-10 Settembre Prof. Dr. Ing. Signe Kjelstrup Non-Equilibrium Thermodynamics: Foundations and Applications 13-16 Settembre Prof. Dr. Dick Bedeaux Non-Equilibrium Thermodynamics of Heterogeneous Systems: The Square-Gradient Model Why these two invited lecture series in Brescia? 7-10 Settembre Prof. Dr. Ing. Signe Kjelstrup Non-Equilibrium Thermodynamics: Foundations and Applications 13-16 Settembre Prof. Dr. Dick Bedeaux Non-Equilibrium Thermodynamics of Heterogeneous Systems: The Square-Gradient Model Teaching Thermodynamics to Engineers • Not just stable and homogeneous equilibrium states, folks! • Stop teaching entropy as an equilibrium-only property! • Nonequilibrium is central in industrial research in all fields •Heterogeneous states (capillary and surface tension phenomena) dominate the micro- nano- bio- world • The next generation of engineers, physicists, chemists, and biologists must learn to team up to gain better control of nonequilibrium states and take fuller advantage of their spontaneous tendency towards equilibrium Interface description Interface description Cahn-Hilliard theory also van der Waals square gradient model or diffuse interface or phase field model Filling the gaps between physics, chemistry, and engineering 7-10 Settembre Prof. Dr. Ing. Signe Kjelstrup Non-Equilibrium Thermodynamics: Foundations and Applications 13-16 Settembre Prof. Dr. Dick Bedeaux Non-Equilibrium Thermodynamics of Heterogeneous Systems: The Square-Gradient Model Don't forget pioneering contributions by others to the same goal, e.g., by the Keenan school of Thermodynamics: from engineering, to physics, to mathematical-physics, and back!
