As part of the 2D-ENGINE dissemination and community building, this two-day workshop at ESRF (December 10–11) will convene the Grenoble-area and broader European community working on 2D materials and interfaces: ESRF beamlines and local labs (CEA, CNRS/UGA), members of the Graphene Flagship initiative, students, postdocs, and interested users. The goal is practical exchange and collaboration: tutorial-style talks that connect synthesis routes with in-situ/operando characterization and device-relevant interfaces, and that help align experimental needs toward joint proposals and shared workflows.
