In the thesis project we want to take advantage of our recent advances in 3D printing combined with the development of integrated dynamic nuclear magnetic resonance devices to study operating systems by NMR and perform in situ or operando experiments. We wish to apply these developments according to an important area of ??research in the field of energy: the identification and study of migrations of different molecular species generated during the operation of an organic redox flow battery (RFBO).
In this purpose it will be necessary to build a mini battery that will be integrated within a conventional NMR magnet. The solution flow in each of the compartments will be driven using our patented mini bubble Pump approach. Here the modularity of our low cost system will allow us to follow spectroscopy and imaging different molecular species in several positions of the battery. The components and geometry will be adapted to organic flow cells, the main goal being to understand and analyze the degradation mechanism and products of the redox molecule (anthraquinone derivatives) on the redox cycle.
The work requested from the doctoral student will go from a strong implication in the design of the mini-battery, to its construction and the magnetic resonance studies. In this area, dedicated protocols and new sequences, using both spectroscopic and recent MRI techniques, will have to be developed.
