| 报告介绍 | Abstract:
Classical thermodynamics is concerned with the fundamental laws of nature and quantitative relations among different macroscopic variables such as various forms of free energy, temperature and chemical composition. Its application requires either experimental data for the calorimetric and/or volumetric properties of a specific thermodynamic system under consideration, or statistical-mechanical models to connect those properties with the molecular composition and suitable macroscopic constraints. Whereas the thermodynamic properties of a macroscopic system are inevitably related to its microscopic structure, neither the structure nor structure-property relationships are explicitly defined in classical or statistical thermodynamics. Structural thermodynamics is built upon a formally exact mathematical framework to quantify microscopic structure along with the properties of thermodynamic systems following the variational principle of equilibrium. It represents a generalization of the classical thermodynamics augmented with explicit structure-property relationships. This talk introduces the basic ingredients of structural thermodynamics to define the structure of a macroscopic system and its connections with various thermodynamic properties. Illustrative examples will be given in terms of phenomenological models for understanding phase transitions in complex molecular systems and the density functional theory for materials design and molecular screening.
Biography:
Dr. Jianzhong Wu is a professor in the Department of Chemical and Environmental Engineering and a cooperating faculty member in the Mathematics Department at the University of California at Riverside. He received his Ph.D. in Chemical Engineering from the University of California at Berkeley, M.S. and B.E. in Chemical Engineering and B.S. in Applied Mathematics from Tsinghua University at Beijing. Dr. Wu’s research is mainly focused on the development and application of liquid-state methods, in particular the density functional theory, to study phase transitions and the physicochemical properties of confined fluids, soft materials and biomolecular systems. |
