“Dielectric Properties in Dense Heterogeneous Systems in an Aqueous Environment”

Relaxation dynamics associated with interfacial polarization of heterogeneous systems immersed in aqueous electrolytes are important to a variety of fields and disciplines. The system we study is composed of conductor mixtures and our early focus has been on low-frequency transitions in the dielectric response observed in dense systems. These indicate a change the charging dynamics brought about by ionic interaction during the relaxation process. This is of particular interest to applications of electromagnetic contrast and biological systems that rely on collective responses of polarizable entities. Results from these early studies of granular systems have pushed our research into new areas and my talk will include aspects of nearest-neighbor interactions in these systems and non-equilibrium dynamics of apparently simple water systems.
