My proposal RT-MAP has been successfully evaluated in HORIZON-MSCA-2022-PF-01 call. Here we will develop novel hollow iron oxide particles and assess their reactivity, stability and mobility under flow through porous media. Such hollow magnetic particles (h-MPs) have aroused great interest for their potential to encapsulate and control reagent release for environmental remediation and/or heterogeneous catalysis. Most available reactivity assessment studies rely on the interpretation of breakthrough curves measurement at the outlet batch tests or column experiments and do not allow a direct visualization of pore scale transport and reaction phenomena. RT-MAP will develop novel microfluidic cells, providing a new window on coupled flow and reaction processes at the microscale, a key to modeling and predicting macroscale reaction rates. The combination of complementary expertise of the fellow (material synthesis and characterization), and the supervisor and cosupervisors (molecular geochemistry, reactive transport in porous media, microfluidics) will offer a unique opportunity to address these emerging scientific questions.
