When interfaces are formed at the junction between materials and liquids, surprising emergent dynamical properties not present in either parent phase can spontaneously coalesce at the interface. Examples include the emergent catalytic, photochemical, electrochemical, and dynamical properties that form at solid-liquid interfaces made possible through the concerted interaction of ionic and electronic degrees of freedom between the two phases. These intriguing interfacial properties are driven by the dynamical and often coupled mechanisms operative at solid-liquid interfaces, including: ionic exchange, electron transfer, photo-excitation, strong electric fields, solvation, surface reconstructions/interphases, and non-equilibrium transition pathways. Enhanced control and understanding over coupled ionic and electronic dynamics across solid-liquid interfaces are poised to drive important material advances in energy, sensing, and computing applications; impacting broadly across fields such as low power computing, energy storage, superconductivity, solar fuels, and atmospheric carbon capture.
Despite the growth in applications and intensive ongoing research, the fundamental nature of the short timescale and small length scale processes at solid-liquid interfaces are not well understood due to the inherently far from equilibrium charge dynamics often present. To enable dramatic performance enhancements, leading theoretical and experimental efforts seek to understand the precise correlation between ionic and electronic dynamics across solid-liquid interfaces at ultrafast spectroscopic timescales and nanoprobe accessible dimensionalities. Some examples include a deeper understanding of multi-step reaction kinetics at solid-liquid interfaces, including the intricate balance between ionic motion and electron transfer, as well as the role of non-equilibrium excitations due to light interactions and coupled driving electric fields arising under external bias potentials in catalytic, photochemical, and electrochemical reaction processes.
This symposium's primary focus is on exploring the coupled relation between ionic and electronic transfer dynamics at solid-liquid interfaces, with an eye to understanding and engineering the coupling between these phenomena. The symposium will encompass complementary theoretical and experimental characterization presentations seeking to design and map electrostatic and electrochemical processes at solid-liquid interfaces. The aim is to present leading examples over the full range of research from fundamentals to near-future energy, computing, and sensing technological applications.
Invited speakers will be drawn from diverse backgrounds in the characterization and modeling of solid-liquid interfaces. This varied group will provide the broad platform necessary to offer a critical and timely assessment of coupled ion and electron dynamics at solid-liquid interfaces phenomena while offering the fertile environment needed to catalyze new interdisciplinary breakthroughs. A special emphasis will be dedicated to a generalized presentation on how the charge transfer dynamics at solid-liquid interfaces can be systematically engineered at short timescales and small length scales to complement, enhance, and surpass existing solid-liquid based energy and electronic device technologies.
