The development of specific liquid-liquid extraction operations is crucial for various bio-chemical processes, such as the production of biofuels. This technique is based on the differential solute affinity between two immiscible liquid phases.

Unlike conventional emulsions stabilized by surfactant molecules, Pickering emulsions are stabilized by nanoparticles. Because of their extreme stability to coalescence, they find numerous applications in several industries (agrifood, pharmaceuticals, chemical industry).

The advent of Machine Learning techniques (ML) is stimulating modern computational chemistry. This methodology may open avenues to address challenging questions in catalytic reactions involved in biomass derived molecules transformation.

In numerical simulation, the discretization of physical models made up of partial differential equations often gives rise to non-linear algebraic systems. The resolution of these systems is generally not easy, due to the large number of unknowns and especially their non-linear character.

The current energy crisis coupled with an unprecedented climate situation is bringing onshore and offshore wind energy to the forefront. For many years, IFPEN has focused its strategic axes to become a major actor of the energy transition and to allow wind energy to become competitive.

An emerging approach is expected to change the way of designing and assessing future mobility of people and goods. Whether it will be more electrified, connected, automated, digitalized or not, it will depend on which targets we aim to reach at given time horizons: environmental, economic, societal, etc.

To meet environmental objectives, one of the main levers is the electrification of the vehicle fleet. This will lead to a sharp increase in the production of Li-ion batteries over the next decade. For environmental and geostrategic reasons, recycling of these batteries in Europe will have to be implemented.

Following the rapid emergence of electric vehicles on the automotive market, manufacturers are seeking to regularly improve the performance of their products in order to stand out from the competition.

CFD simulations are currently used for the design and optimization of propulsion and industrial devices involving chemically reactive flows. They facilitate the research of new solutions that allows to reduce CO2 and pollutant emissions.

IFP Energies nouvelles (IFPEN) is a major research and training player in the fields of energy, transport and the environment. From research to industry, technological innovation is central to all its activities, structured around three strategic priorities: sustainable mobility, new energies and responsible oil and gas.
