Doctoral theses

Under the European Green Deal, the demand for advanced secondary batteries is a pressing challenge. Critical for the impending energy transition, these batteries are instrumental for advancing the electric vehicle market, a linchpin for EU industrial and economic expansions.

Understanding the hydro-sedimentary dynamics at the watershed scale in response to daily or multi-year forcing is a key challenge in assessing the impact of climate change on water resources.

INRIA and IFP Energies nouvelles, leading French research laboratories, are seeking a talented and motivated master's student to join their team for a PhD position. As numerical simulation plays a pivotal role in our research and industrial applications, optimizing the performance of our parallel simulators is crucial.

Electric cars contribute to the de-carbonization of the transport sector and their massive deployment is foreseen. In this context, the battery industry strives for ever improved technologies, both in terms of performance and safety.

It is now established that molecular hydrogen (H2) exists naturally on the planet in the form of diffuse or continuous emanations. However, many questions remain unanswered as to its origin, formation mechanisms and real potential for exploitation.

The numerical discretization of physical models representing evolutionary problems in many fields leads to nonlinear algebraic systems of very large dimensions. The process of solving these systems, which must be carried out robustly and rapidly at each time-step in order to increase software efficiency, comes up against a number of obstacles.

As part IFPEN activities on Energy Transition Sustainable Development, a doctoral thesis is proposed in the Electrochemistry and Materials Department at IFP Energies Nouvelles Solaize, 10 km from Lyon, in collaboration with the company APERAM (CIFRE funding).

The numerical discretization of physical models in many fields leads to very large nonlinear algebraic systems. The resolution of these systems, which is usually achieved by successive linearization like Newton's method, needs to be fast in order to increase software efficiency.

In the context of reducing the environmental impact in polymer manufacturing, the use of recycled plastics will rise. Mechanical recycling is simple and economic, but faces limitations in product quality and appearance.

Producing renewable fuels and chemicals from biomass is mandatory in the fight against climate change as well as land and sea pollution. Fatty acids, derived from the lipid fraction of biomass, are oleochemical molecules of choice for the manufacture of biodegradable surfactants, cosmetics, lubricants and polymers.

The importance of air quality cannot be underestimated as it represents a major public health issue: today, nearly 91% of the global population is exposed to air pollution levels exceeding the exposure thresholds set by the WHO. This thesis lies at the intersection of three scientific domains: numerical modeling, air quality, and deep learning.

Through various research programs, IFP Energies nouvelles is now strongly involved in the development of bioprocesses to produce biofuels and bio-based chemical intermediates.
