the membrane area needs to be scaled up for future practical technology development. Mechanical
properties of the membrane under various temperatures need to be also evaluated.
The novel concept demonstrated here is not limited to ionic oxide material. Beyond fuel-cell applications,
the host layer materials (if functionalized with appropriate ligands) could potentially serve as membranes
for waste water clean-up, biomolecule separation, synthesis of uniform macromolecules (dendrimers), and
mining applications. Furthermore, many different kinds of nanocrystalline oxides or non-oxides
(metals/alloys, nitrides) can be developed in the nanopore channels of our unique host matrix layer to take
advantage of the nanocrystal confinement and oriented interfacial effects. For example, proton-
conducting oxides or polymers can be prepared as guest phases confined in nanopore channels for proton
membranes. Such nanocomposite membranes could also lead to a new generation of electrochemical
sensor materials for H2, NOX, etc. The designed nanocomposite membranes could be used for solar cells,
membrane catalytic reactors (desulfurization by hosted Mo2N nanophase), hard-disk memory (magnetic
recording with high signal-to-noise ratio), or for electronic/optical devices (when guests are
semiconductors such as CdS). In summary, the R&D and application opportunities for our novel
nanostructured membranes are very broad.
