| 1. A method, comprising:
providing a plurality of particles, at least some of the particles comprising a first material that is solid at a service
temperature and a second, entrapped material that is fluid at the service temperature, wherein the first material and the
second, entrapped material are in nanoscale proximity such that each atom of the first material is positioned within less
than about 1 micrometer of at least one atom of the second material;
applying pressure to the particles sufficient to cause at least a portion of the first material to exhibit fluidity at a temperature
at which, in the absence of the pressure, the portion of the first material remains solid, and that causes mixing of at least
some of the first and second material together;
releasing the pressure to form an article that is a composite of the particles and that has a defined structure at the service
temperature.
