The U.S. National Nanotechnology Initiative (NNI) and European Commission (EC) have organized the ninth annual meeting of the environmental, health, and safety effects of nanomaterials (nanoEHS) Communities of Research (COR) as a virtual workshop on September 16-17, 2020. According to NNI, as the nanoEHS research ecosystem continues to evolve, the workshop 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. NNI states that 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. The workshop will run for four hours each day. Webcast plenaries will include a live question and answer portion. Breakout sessions will feature interactive discussion. The draft agenda is available. Registration is free.
