Physical Chemistry and Electrolyte Interfacial Nanosystems Laboratory (PHENIX) - UMR 7195

The PHENIX Lab (PHysicochimie des Electrolytes et Nanosystèmes InterfaciauX), jointly supervised by Sorbonne Université and the CNRS, was launched on 1 January 2014 following the closing of the PECSA Lab (Physical Chemistry of Electrolytes, Colloids and Analytical Sciences).

The PHENIX Lab is associated with the Chemistry (section 13) and Physics (section 5) institutes of the CNRS. It also belongs to the Faculty of Chemistry of Sorbonne Université and is part of the Federation Research Institute of Materials Centre Paris (FR 2482).

The PHENIX's research activity focuses on the physical chemistry of electrolytes and multiscale interfacial materials, such as colloidal systems and porous materials. One of its main features is the strong coupling between experiments and modeling. Different research topics include the development and functionalization of inorganic nanoparticles, the use of multi-scale magnetic materials for environmental applications, the development and study of the behavior of magnetic particles in the framework of biomedical applications, the study of molten salt for the upstream and downstream of the nuclear power cycle, the energy storage in batteries and supercapacitors where the development of new original electrodes and the understanding of their functioning are essential, modeling and experimental results of the transport properties and confined fluid retention of charged species and in multiscale interfacial systems. These topics can be distributed according to three themes with high social impact: energy, health and the environment.

Researchers in PHENIX have a triple set of skills: recognized expertise in testing and chemical synthesis, the ability to implement numerical simulations in a very wide range of scales of length and time, and their capabilities in the development of suitable theoretical models.

Teams and research themes

Three teams and two transversal axes structure the PHENIX Lab:

- The Inorganic Colloids team, led by C. Cleaning: The scientific activity of this team is centered around three themes: (i) the development of methods of synthesis and dispersion of magnetic mineral nanoparticles with among others a microfluidic axis and ionic liquids as synthesis media theme; (ii) microscale and nanoscale magnetic particles in the context of biomedical applications: imaging, vectorization, hyperthermia; (iii) the magnetic material for the multi-scale environment.

- The Electrochemistry and Ionic Liquids team led by H. Groult: The scientific activity is centered around three main themes: "high-temperature ionic liquids", "ionic liquid at room temperature" and "materials & Nnanoelectrochemistry." The transversal theme "Energy and Fluor" remains a major focus and fits in the Lab's triptych of Energy, Health and Environment.

- The Multiscale Modeling and Experimentation team moderated by Mr. Jardat: The scientific activity is centered around two main themes: "coupled transport in complex fluids" and "transport in porous media: new challenges, new approaches." A transversal theme "development of methodological tools" to develop new methodologies, both experimental and modeling, to provide new tools for research purposes.

- The transverse axis studying multi-scale transport by low field NMR facilitated by A.-L. Rollet: This axis is based on the skills already present within PHENIX and the dynamic development of a NMR platform at Sorbonne Université. Two NMR experiments have been chosen to start: the field cycling relaxometry (NDMR) and low-field NMR to perform experiments of pulsed field gradient (PFG-NMR). These methods are developed in particular to study and understand of transfer of multi-scale fluid in porous hierarchical structures.

- The transversal axis on 3D X-ray imaging of materials and environmental benefits of colloidal systems hosted by L. Michot and P. Levitz: This theme explores the opportunities and recent developments in micro-and nano-ray tomography X. The goal is to perform morphological and topological analysis (and sometimes functional analysis by coupling with spectroscopic techniques) of the interfacial nanosystems studied in PHENIX.
