The research network GDR CohereX (Science with coherent X-rays at 3rd and 4th generation synchrotron sources) will take place from the 7th to the 9th of October 2025, at SOLEIL. It aims to gather the French community using coherent X-rays covering a wide range of research fields from biological systems to magnetic and electronic structures over functional materials and cultural heritage materials up to the dynamics of matter. The General Meeting of the GDR CohereX aims to present the latest research results using coherent X-ray techniques and to share the know-how. They also aim to promote the development of innovative studies and data analysis approaches, in particular, with respect to the unique opportunities offered at upgraded extremely brilliant synchrotron sources.

Ce colloque francophone bisannuel a pour vocation de réunir l’ensemble des communautés qui utilisent et développent l’instrumentation des rayons X pour l’étude de la matière avec pour visées tous les champs d’application répondant aux besoins et aux défis sociétaux.

L’école porte sur la détermination des structures et des microstructures à l’échelle nanométrique par diffraction électronique dans un MET. Elle concerne les développements récents associés à l’utilisation de techniques d’acquisition et d’analyse des données avancées telle que la précession en mode tomographie (PEDT), les affinements dynamiques et la cartographie de phase et d’orientation en 4D-STEM . Les méthodes d'analyse de symétrie en faisceau convergent seront également présentées.

L’ANF "Méthodes innovantes en cristallisation et cristallographie des macromolécules biologiques" (RECI-TECH 2025), portée par les réseaux ЯÉCIPROCS et CRISTECH et en partenariat avec le synchrotron SOLEIL, aura lieu au synchrotron SOLEIL du 8 au 11 Décembre 2025. Elle portera sur des problématiques de cristallogenèse pour la cristallographie sérielle et les nouvelles stratégies pour la collecte et l’analyse des données de diffraction.

We are excited to welcome you in Bordeaux for the 4th edition of the Integrative Structural Biology Meeting (BSI), co-organized with the Association Française de Cristallographie (AFC) and the Société Française de Biophysique (SFB). We are currently experiencing a historic and transformative shift in structural and cellular biology, driven by groundbreaking advancements in super-resolution optical microscopy and cryo-electron microscopy. These technologies are surpassing previous resolution limits, enabling unprecedented insights into the architecture of proteins, organelles, cells, and tissues. This opens the door to a more comprehensive, multi-scale understanding of biological systems. As a result, structural biologists, biophysicists, biochemists, and cell biologists are becoming increasingly interconnected. By sharing our knowledge and innovations, we can explore structural biology in greater depth and uncover the full complexity of its underlying mechanisms.

This invaluable forum for the synchrotron radiation users’ community will provide the opportunity to exchange and learn about the evolution of the machine and the beamlines. It will be also the occasion to share scientific, technical and practical issues about the synchrotron radiation use.

The development of vacuum-compatible liquid sampling sources has enabled the use of ionizing radiation sources (XUV and X-rays) to study reaction dynamics in solution. This development is constantly evolving with improvements in light sources, such as the relative democratization of laser sources based on high-order harmonic generation, and improvements in liquid targets with the recent development of stable flat liquid jets with sub-micrometer thicknesses. The transvers nature of reaction dynamics in water across different scientific communities means that the spectroscopic tools available are extremely varied. These include time-resolved photoemission spectroscopy (femtosecond and even attosecond), highly nonlinear optics via liquid-phase HHG, chiral linear probe development (circular X-ray dichroism, PECD), RIXS, coincidence measurement (e-,e-), etc. This workshop will bring together users of these different tools. It will also provide an opportunity to compare and improve theoretical aspects of molecular dynamics in the liquid phase, thanks to the participation, we hope, of European experts in the field.
