Volume II, Chapter 7, where we deal with thin film properties and surface micromachining. In the case of nanoparticles, deviation from expected bulk theory is even more pronounced (see Chapter 3 on quantum mechanics and the band theory of solids in the current volume). The crystal structure of a nanoparticle is not necessarily the same as that of the bulk material. Nanoparticles of ruthenium (2-3 nm in diameter), for example, have body-centered cubic (lattice point at each corner plus one at the center; see below) and face-centered cubic structures (lattice points at each corner as well as in the centers of each face; see below) not found in bulk ruthenium.
