Non-Equilibrium Redox Dynamics – NERD

This project advances the understanding of (supra)molecular electrochemical processes in non-equilibrium systems through a collaborative effort between an experimental and a theoretical research group. Electrochemical systems, ubiquitous in modern technology, often operate far from thermodynamic equilibrium. Despite their importance, the mechanisms governing dynamic redox phenomena remain poorly understood (theoretically) and underdeveloped (experimentally). For example, real-time control of dynamic patterns is essentially unprecedented, and the non-equilibrium thermodynamics of surface redox processes remains to be developed.

This project focuses on the interplay between electrochemical reactions and transport phenomena, under non-equilibrium conditions. The french experimental group (60% of person/month - larger research effort) will design and carry out measurements under controlled non-equilibrium conditions to capture real-time data on redox spatial phenomena. The theoretical group (40% of person/month - smaller effort) will use its expertise in theory and modelling of the nonequilibrium dynamics and thermodynamics of chemical reaction networks, (including diffusion and non-idealities) to extend the theory to account for energy supply via redox reactions at the electrodes, and use it to develop models to interpret and guide the experimental efforts, providing a deeper understanding of the emergent properties of these systems, leading to general design principles.

The researchers hired on each side of the collaboration will focus either on experiments or theory – based on the local expertise – while being frequently exposed to the complementary approach via frequent visits to the partner lab, which will ensure iterative feedback, enabling both the experiments and the models to evolve in tandem.
Leveraging this synergy, this project paves the way for novel electrochemical technologies and deepens our understanding of complex systems far from equilibrium.
