Diffusion controlled oriented growth of a nano porous material by the Kirkendall effect

Nanotubes and nanoporous materials are being made by solid state diffusion utilizing the Kirkendall effect. Recently published manuscripts have shown that the product phase grows with an oriented microstructure. Based on the requirement of relative mobilities of the components to produce a good quality nanoporous material, it is shown that the oriented microstructure will grow invariably in most of the systems.
