Wind energy demands significant space, leading to the grouping of wind turbines into farms with an increasing number of turbines. A drawback of densely packed wind farms is the aerodynamic interference between turbines, causing wake losses.
Thermal runaway (TR) is a major challenge in the development and safety of Li-ion batteries, especially for electric vehicles. When a cell experiences TR, it releases heat rapidly, posing risks of explosion and propagation to adjacent cells.
Transport electrification is a major theme in the energy transition. It involves the use of electric technologies in various modes of transportation, such as cars, buses, bicycles, and others. Permanent magnet synchronous machines are often used in this type of application due to their compact design and high efficiency.
Catalysts are very often made of active phases containing metallic elements (such as platinoids, cobalt, nickel…) considered as strategic or even critical because of the economic strain induced by a growing usage in multiple sectors (industrial chemistry, energy storage, electrolysers, …) Hence, the quest for a circular economy approach brings n
The design of innovative materials is a prerequisite for the successful development of future thermochemical processes such as high-temperature heat storage and green hydrogen production. Oxygen carriers are a family of materials used in such applications to absorb and release oxygen cyclically while delivering and storing heat respectively.
A detailed understanding of Neolithic ceramics plays a crucial role for archaeologists, providing insights into ancient manufacturing techniques and shedding light on social connections and ancient human movements.
La découverte de phases actives de catalyseurs hétérogènes représente un enjeu majeur dans le contexte de la transition énergétique.
The impact of climate change and human activities on the water resource evolution is today a major concern for our societies. Managing karst aquifers requires an in-depth understanding of hydrodynamic flows, considering the heterogeneity of the geological reservoir.
Because of their very low polarity, carbon-hydrogen (C-H) bonds are particularly difficult to activate. However, their ubiquity in organic molecules makes their activation and functionalization particularly interesting.
The aeronautics sector must rapidly evolve to further improve aircraft energy efficiency. This involves the evolution of fluids, the modification of system architectures and, of course, the optimization of these two items to ensure a safe operation. The degradation of aeronautical oils is one topic that has to be addressed.
The study of processes such as CO2 injection in the underground or geothermal energy requires to simulate flows and geomechanics in cracked porous media in a coupled way. Cracks have a major influence on the hydraulic conductivity since they can be highly permeable.
The Li-ion battery is the technology shared by all automakers to provide the energy storage required for the deployment of electrified vehicles. During its life cycle, a battery may encounter a wide range of operating conditions.
