Thousands of per- and polyfluoroalkyl substances (PFAS) have been synthesized since the mid-20th century. These compounds, selected for their exceptional properties, find many applications in our daily lives, including waterproofing textiles, packaging, and non-stick coatings for kitchen utensils.

Lithium (Li) is a lightweight alkali metal with a high electrochemical potential, making it a critical element in the energy transition. However, its demand is projected to increase 42-fold by 2040, positioning Li as a resource under significant criticality.

Reports and studies warning of potential future tensions in raw material markets essential for the low-carbon and digital transition have multiplied in recent years.

In the pursuit of energy transition, optimizing catalytic processes is essential for the efficient and sustainable conversion of raw materials into biofuels. At the heart of this optimization lies a deep understanding of atomic-level reaction mechanisms.

IFP Energies Nouvelles is seeking a motivated PhD candidate to participate in a cutting-edge research project focused on the development of a new hybrid combustion model for gas turbines.

In the face of current environmental challenges, the shift towards more sustainable mobility is a key focus. European governments have outlined a roadmap to promote the adoption of public transportation, integrate new energy sources and reduce the reliance on single-occupancy car use, also known as “car-solo”.

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.

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.
