NIA is delighted to welcome UK-based Promethean Particles as a new Corporate Member.  Promethean operates the world’s largest continuous multi-material nanoparticle manufacturing plant, using continuous hydrothermal synthesis, where nanoparticulate materials are produced by mixing superheated/supercritical water with a solution of a metal salt (rather than slowly heating the entire contents of a batch vessel) with two fluids continuously mixed together.
