The U.S. National Nanotechnology Initiative (NNI) and European Commission have organized the ninth annual meeting of the nanoEHS Communities of Research (CORs) as a virtual workshop on September 16-17, 2020. As the nanoEHS research ecosystem continues to evolve, this event will identify future needs and opportunities. Conversations will further address how the lessons learned from nanoEHS research can be applied to other areas such as emerging technologies and incidental nanomaterials. The workshop will foster high-level discussions of nanoEHS and related areas to explore connections and synergies that will drive responsible development into the coming decades.
