From page 60...
... The actual local atomic nature of nanophase boundaries needs to be further-elucidated in general, and atomic resolution electron microscopy on nanophase materials can be expected to facilitate such an elucidation. Beyond such studies of atomic structure, x-ray and neutron small-angle scattering can also be useful tools for the study of grain- and pore-size distributions and grain boundry characteristics, particularly as a function of sintering temperatures, as shown by recently completed small-angle scattering investigations (Epperson et al., 1989; Wallner et al., 1989~.
