The main objective of this congress is to bring researchers together to discuss the progress of operando methodologies, i.e. characterization of functional materials in their working state. In operando studies, physicochemical methods probe the behavior of working materials while their performance is measured simultaneously. The operando approach is suited to elucidate catalyst structure-activity relationships at the molecular level. Both academia and industry recognize the importance of this approach that is now a well-established research area in catalysis.

The theme of this meeting is “Multiscale, Multimodal Microscopy for Multidisciplinary Research”. In recent years, microscopy technologies have become increasingly diverse and sophisticated, enabling seamless observation across scales from nano to macro and combining different modalities to generate new insights. Furthermore, interdisciplinary research is rapidly expanding, fostering integration across a wide range of fields, including medicine and life sciences, materials science (metals, inorganic, physical, and chemical), and information science.

The 249th ECS Meeting takes place at the Seattle Convention Center in Seattle, WA, from May 24–28, 2026. Anchored by the theme Sustainable Technologies, the meeting underscores the vital role of electrochemistry and solid state science in addressing today’s most pressing sustainability challenges. From clean energy and decarbonization to circular materials and climate-resilient systems, international researchers from academia, industry, and government come together to share breakthroughs that reduce emissions, conserve resources, and advance a more sustainable future. Through oral presentations, panel discussions, poster sessions, tutorials, and exhibits, the 249th ECS Meeting spotlights cutting-edge innovations that drive climate action, resource efficiency, and long-term planetary health.
