嘉宾简介：

Rudolf Podgornik is Chair Professor at the University of Chinese Academy Sciences in Beijing. He is a National Program Expert with a National Specially Appointed Foreign Expert Honor. He specializes in soft matter physics, macromolecular physics and biophysics, with particular emphasis on Coulomb fluids, Lifshitz theory of van der Waals dispersion interaction and the Casimir effect, membranes, polymers, polyelectrolytes and physics of DNA, RNA and viruses. He authored more than 400 scientific articles and edited two books that were cited more than 10000 times, making an outstanding contribution to global scholarship.

报告摘要：

I will present some recent results regarding the electrostatic interactions in different soft matter systems, mostly focusing on the various effects that explicit inclusion of dissociation, the s.c. charge regulation, has on the effective Coulomb interactions. The relevant systems will include charge regulation of charge multipolar moments in proteins, then specifically charge dissociation mechanisms in viral proteinaceous shells, the symmetry breaking that can be driven by charge regulation, the anomalous screening in macroion electrolyte solutions as well as the related Casimir-type fluctuation interactions.
