Development of a LES combustion model for NH3/H2/air flames accounting for preferential diffusion and high Karlovitz regime coupled to a multicomponent Real Fluid Model (RFM)

Join a cutting-edge European research network!
As part of the MSCA-DN DT-HATS project, this PhD study addresses a high-impact challenge: developing a next-generation simulation framework for hydrogen/ammonia (H₂/NH₃) dual-fuel combustion, two key energy carriers in the path toward carbon neutrality.

Hydrogen consumption kinetics by subsurface microbial communities: what impact on natural hydrogen flows to the surface?

It has been established that molecular hydrogen (H₂) is present on the planet in the form of diffuse or continuous emanations. Nevertheless, many questions remain regarding its potential for exploitation. Hydrogen is an important electron donor (reductant) for subsurface ecosystems.

Amélioration d’image, super résolution et classification d'images par l'IA : Application à la microscopie holographique numérique

Digital holographic microscopy (DHM) has emerged as a powerful and transformative imaging technique, offering label-free, non-invasive visualisation of cellular structures and dynamic processes with exceptional sensitivity. Such a technology offers great promise for neuronal studies because it is label-free and quantitative.

Development of a LES method for characterising the impact of mixture preparation on combustion stability in H2 SI engines

Europe has outlined its plan to pursue its ecological transition, known as the ``Green Deal'', through the implementation of a series of political initiatives. Different road transport technologies support this transition, such as electric propulsion powered by batteries and fuel cells, or internal combustion engines running on hydrogen.

Towards a comprehensive understanding of reaction mechanisms of « Lytic polysaccharide monooxygénases » (LPMO) for an optimized hydrolysis of recalcitrant lignocellulose substrates

Biofuels are one of the solutions for reducing the combustion of fossil fuels and global greenhouse gas emissions. Second generation bioethanol is produced from lignocellulosic substrates which are not in competition with food production, but the economic viability of the process depends on an efficient enzymatic hydrolysis.

Deep fusion of hyperspectral images to enhance polymers recycling: from a better characterization to cross-modal generative models

The increasing demand for plastics and the need for efficient recycling are critical issues in waste management due to the complexity of separating mixed polymers and impurities. Despite advancements, current recycling rates remain low, largely because of the difficulty in accurately sorting plastic waste.
