ENGINEERED AEROSOL PARTICLES, AND ASSOCIATED METHODS

摘要

An engineered aerosol particle for use in aerosol applications is provided. The engineered aerosol particle comprises a fabricated nanoparticle body member being non-spherical. The fabricated nanoparticle body member is configured to provide at least one of auto-rotation, tumbling, or lift when entrained in an airstream to thereby increase settling time of the fabricated nanoparticle body member. An associated method is also provided.

主权项

1. A collection of engineered particles, wherein each particle comprises:
a fabricated nanoparticle body member being non-spherical and configured to provide tumbling when entrained in an airstream to thereby increase settling time of the fabricated nanoparticle body member, wherein the nanoparticle body member has a three dimensional shape consisting of;
a longest dimension defining a longitudinal axis of the three dimensional shape; a uniform thickness; and,
an off-center fenestration wherein the off-center fenestration provides the particle with one dimension of symmetry and a center of mass offset from the longitudinal axis.
