CSN faculty members Joel Pedersen and Rebecca Klaper will participate in a workshop at the Duke University Center for the Environmental Implications of NanoTechnology (CEINT) entitled Environmental Nanomaterial Testing Media Harmonization, or ENTM Harmonization. The goal of this workshop is to develop user-community-driven recommendations for consistently characterized, relevant media types in which nanomaterial characterization and testing should be carried out, along with recommendations for consistently captured characterization parameters. The outcomes of the meeting will be captured in a peer-reviewed manuscript.
