The interaction of guest species with the interior of porous materials are critical process in the fields of gas capture (CO2, H2O), gas storage (CH4, H2) but also Catalysis and battery technology. We explore unique gas adsorption processes such negative gas adsorption which is based on the release of gas from a porous metal-organic framework via self-induced pore contraction. We also explore how to use framework flexibiltiy to improve water capture capabilities and lower the energetic footprint of adsorption processes. Based on our research on dynamic porous materials we investigate activated transport processes in which the transport of molecules and ions is actively stimulated. Our current research focuses on the utilization of framework dynamics to activate ionic transport in semi-solid electrolyte systems for enhanced ionic mobility in battery systems of multivalent ions such as Mg.
