The postdoctoral fellow will participate in the SENSES (making Sense of Electrical Noise by Simulating Electrolyte Solutions) research project, coordinated by Benjamin Rotenberg. The general objective is to provide an integrated understanding of electrical fluctuations in bulk, interfacial and confined ionic fluids.
In this context, the post-doctoral fellow will investigate how much information can NMR relaxometry experiments actually provide on the multiscale dynamics of individual ions. For quadrupolar nuclei, the relaxation of the magnetization reflects the fluctuations of the electric field gradient (EFG) at the nucleus. Using molecular dynamics simulations, parametrized on prior ab initio calculations, this project will examine specifically the effect of fluctuations of the solvation shell and of the ionic cloud around each ion. The possibility to extract information on these mechanisms from experiments will be examined in collaboration with the experimentalists expert of NMR relaxometry in the PHENIX laboratory.
The postdoctoral fellow will in particular:
• develop new theoretical approaches to model and interpret electrical noise in electrolyte solutions
• perform molecular simulations
• develop software to analyse these simulations (based on existing tools available in the laboratory)
• interact with other participants in the project and experimental collaborators
• disseminate research via scientific publications and conferences
Candidates should have at the beginning of the contract a PhD in Physical Chemistry or in Physics, as well as a research experience relevant for the topic/activities of the present project. A good experience in molecular simulation is expected, as well as a good knowledge of the associated theoretical and numerical tools (Statistical Mechanics of liquids...; some programming skills in at least on of: Python, Fortran, C, C++, ...). Written/oral communication in English is necessary (knowledge of French is not).
The PHENIX laboratory (Physical chemistry of electrolytes and interfacial nanosystems) is a joint research unit between CNRS and Sorbonne Université. It is located on the Pierre et Marie Curie Campus, in the center of Paris. It consists of ~90-100 people, including academic staff, PhD students and postdoctoral fellows, and conducts research in the fields of Energy (electrochemical storage, recycling...), Health (nanoparticles for imaging, ...) and Environment (waste disposal, water treatment, ...).
The postdoctoral fellow will be part of the "multiscale modelling and experiments" group and conduct research in the framework of the ERC project SENSES. Access will be provided to computational resources at the lab and University levels.
