turbulEnt Dense Gas flow modeling using large Eddy Simulation – EDGES
This Young Researcher Project proposes to introduce Large Eddy Simulation (LES) in the field of Organic Rankine Cycle (ORC) turbine flow modeling. No prior study has been focused on the accuracy and relevance of current subgrid-scale (LES) or statistical (Reynolds Averaged Navier-Stokes or RANS) mo
Exploring geological resources and reservoirs Integrity by geophysical prospecTING of clays properties from nano to field scale – ExCiTING
The central objective of the project is to improve the geophysical imaging of clay formations and to detect the presence of mineralization that generates a complex resistivity response, from the earth surface to the cover of the targeted reservoirs. The complex resistivity presents an interesting se
Hydrothermal transformation of cellulosic substrates assisted by photocatalysis – PHOTHER
Fossil resources are not inexhaustible and a source of pollution. The objective is then to replace them with one of the most important renewable sources of carbon, the cellulosic part of lignocellulosic biomass, which is inedible. However, nowadays high pressure and temperature and expensive materia
paramagnetic NMR shifts in actinide complexes : beyond the lanthanide model – ACTIpNMR
The presence of covalency in complexes of the 4f and 5f elements has been a source of intense research and controversy. This covalency have been probed by many spectroscopies, but there has been little use of NMR. The NMR shifts of paramagnetic substances have two contributions; the dipolar term ar
Sustainable catalytic process for the “One-pot” formation of cyclic carbonates through oxidation of alkenes and CO2 cycloaddition – OxCyCat-CO2
Global warming is one of the greatest challenges facing humanity and it is now essential to find solutions to limit the concentration of greenhouse gases, including CO2, in the atmosphere. To achieve this, chemistry provides solutions that allow CO2 to be regarded not as a waste product, but as a so
Ultradispersed metal catalysts for energy applications involving hydrogen – UltraCat
Heterogeneous catalysis is a crucial process for saving and producing energy. It often involves precious metals, the amount of which must be drastically reduced for a sustainable human development. Last-generation electron microscopes have recently enabled the emergence of so-called supported “singl
Dynamics and instabilities of helical vortex pairs – TWIN-HELIX
The aim of this project is to gain new basic knowledge on the dynamics and instabilities of vortex pairs having a large-scale helical geometry, which have relevance to applications involving flows around rotors. These applications include the wake generated by a helicopter and the flow behind a hori
Towards a better assessment of hydraulically induced damage in geo-engineering applications – HydroGeoDam
Predicting occurrence of hydraulically induced damage in geological systems constitutes a major challenge in subsurface engineering. For instance, geo-resources completion, underground storage management or even building and maintenance of construction sites can all be affected by the progressive de

The goal of the project TACOT is to demonstrate the applicability of thermoacoustics for refrigeration in the automotive field. It brings together Groupe PSA and four CNRS research laboratories (Institut P’, LAUM, LIMSI, LMFA), and is organized into three challenges. The first challenge consists in
Catalytic Activation of CO2 towards Carboxylic Acids and Esters Mediated by Organometallic Precursors – CO22CHEM
Carbon dioxide conversion into value-added chemicals through C-C bond-forming reactions has gained considerable interest, as it might constitute a conceivable solution to gradually relinquish the use of fossil fuels / resources in favour of more sustainable carbon resources. The use of CO2 as raw ma
Xenotime as a material for actinides specific storage – x-mas
Nuclear energy appears as an important actor to supply clean and sustainable electricity with low carbon dioxide emission. One of the main challenges facing this industry is related to the conditioning and storage of the generated radwastes. In this framework, ceramic “crystalline” matrices especial
Passive Radiative Cooling – RADCOOL
Very often in thermodynamics, in order to have a good conversion efficiency, it is necessary to have a high temperature heat source and a low temperature heat sink. Now the space which has a temperature around 3 K is a very interesting heat sink ... if we are able to interact with it. However, the E
