  • This description of flow separation successfully captures the observed dependence on the various experimental parameters - wettability, flow velocity, solid surface edge curvature.

    The Guardian World News

  • It is especially challenging for researchers to disperse and stabilize nanoparticles in molten metals (or melts) because most melts have a large surface-to-volume ratio and are unable to maintain contact with the solid nanoparticle surfaces (a quality known as poor wettability).
