报告题目:General formulation and some salient results in charge regulation theory

报告人:R. Podgornik 教授,中国科学院大学理学院,卡弗里理论科学研究所




报告摘要:There are no net charges in (bio)colloid world, and all of them result from dissociation of chargeable groups, as in e.g., proteins from dissociable amino acid moieties, a process in general referred to as charge regulation. Recent advances in the theoretical formulation and analysis of charge regulated system lead to some far reaching conclusions on electrostatic interactions in colloid milieu, that often differ fundamentally from the accepted wisdom. I will present several examples of novel behavior or new understanding of the known behavior that is specifically connected with the response of the charging equilibrium on (bio)colloidal surfaces to the local bathing solution conditions.
