1. A method of inhibiting water vapor adsorption of a powder comprising:
providing a plurality of particles; adding discrete hydrophobic surface modified nanoparticles; exposing the particles to a relative humidity of least 15%; wherein the plurality of particles combined with the hydrophobic surface modified nanoparticles have a lower water vapor adsorption than the plurality of particles alone; and exposing the plurality of particles combined with the hydrophobic surface modified nanoparticles to a relative humidity of least 15%, wherein when a liquid is present, the liquid is a volatile inert liquid that is not a solvent with respect to the particles.
