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.

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.

Le réchauffement climatique à l’échelle de la planète a conduit l’Europe à s’inscrire sur une trajectoire de réduction de sa consommation énergétique et de ses émissions de CO2 avec un objectif de neutralité carbone à 2050.

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.

Le développement des technologies de décarbonation constitue un des piliers fondamentaux de la transition énergétique.

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.

The electrochemical storage of electrical energy has become a global issue and a major challenge. Li-ion batteries are considered as the preferred solution to store energy. Safe batteries systems keep today the weakest link in the development of many energies or power demanding.

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.

L’équipe R&I corrosion du département d’Electrochimie et Matériaux au sein d’IFP énergies nouvelles (Solaize), en lien avec le LaSIE (La Rochelle), propose un poste de thèse captivant sur la compréhension de la dégradation des métaux dans les pr

The global production of plastics is growing exponentially and consequently is the plastic pollution in the environment. At IFP Energies Nouvelles, we develop models that simulate the transport, deposition, and erosion of plastics in the environment.

Context and objectives
During laundry washing, fibers are inevitably shed from textiles and are carried into the wastewater. These fibers, typically around 10 μm in diameter, vary in composition
- mainly polyester and cotton

The energy transition towards renewable sources is a major societal challenge. Optimizing wind farm systems is crucial to maximize efficiency while reducing component wear and tear. However, control algorithms for these systems are often computationally intensive and hard to execute in real-time.
