AbstractIn CO2-rich atmospheres such as that of Venus, the study of water vapor requires the use of H2O collision parameters for CO2. However, due to a lack of data, models still use collision parameters for air to estimate the abundance of water vapor in this type of atmosphere. In this thesis, new experimental laboratory measurements of the collision parameters of H2O, HDO, and D2O by CO2 were carried out. These were then used as the basis for dedicated theoretical calculations. Their impact was evaluated using radiative transfer simulations applied to the atmosphere of Venus, under conditions close to those of future observations by the European EnVision mission. The results clearly show that using collision parameters for air instead of CO2 can lead to an overestimation of nearly 40% of the abundance of water vapor in the mesosphere and to inversion difficulties in the troposphere. This work thus provides essential elements for improving the spectral analysis of CO2-rich atmospheres.JuryDr. Ha TRAN (Sorbonne University), ChairProf. Muriel LEPÈRE (University of Namur), SecretaryDr. Emmanuel MARCQ (University of Versailles)Dr. David JACQUEMART (Sorbonne University)Dr. Laurence RÉGALIA (University of Reims)Dr. Séverine ROBERT (Royal Institute for Space Aeronomy, Belgium)

In line with its predecessors, ICEL 2026 will provide an excellent opportunity for the intellectual and social exchanges that keep our community closely connected. It will bring together participants from all over the world involved in the research, development, and manufacturing of emissive materials. A wide array of subjects will be explored, offering a comprehensive perspective on contemporary advances in these fields. We extend a warm invitation for the dissemination of recent breakthroughs in related topics, with a particular emphasis on fostering the active participation of young and motivated researchers.We especially expect to cover the following topics:Thermally Activated Delayed Fluorescence emittersRadical emittersOrganometallic complexesPerovskitesLasingCircularly polarized luminescenceLight emission from exciplexesGreen- and biophotonicsComputational modeling of light-emitting materialsAll practical information (registration, abstract submission, and accommodation) is available on the ICEL2026 website. Access the ICEL2026 website

Our keynote speakers for 2026 are Professor Roosmarijn Vandenbroucke (Ghent University) and Professor Nelly Litvak (Eindhoven University of Technology). More information on the "Women in Science" website

At UNamur, research is not confined to laboratories. From physics to political science, robotics, biodiversity, law, AI, and health, researchers collaborate daily with numerous stakeholders in society. The goal? Transform ideas into concrete solutions to address current challenges.
