continues to rise at room temperature with time.
Most notably, the level of graphitic-like material
increases in each sample. We have attempted to use
thermal siphoning to remove the cesium after post-
treatment; preliminary experiments indicate that more
than 66% of the original mass of cesium can be
recovered in this manner. These results lend further
credence to the notion that the cesium may be acting
catalytically in transforming carbon from disordered
to ordered nanodomains.

ture 20008C causing vaporization and, hence, de-
fect formation. Under such conditions the nanotubes
form on the face of the cathode, the electrode that is
bombarded with electrons. Logically, given its elec-
tropositive character, the role of cesium is to supply
electrons to the carbon, a step necessary to set off the
process of ordering. The required temperature is low
because the NPC begins in a highly strained form
that is rich in defects. The addition of electrons
provides the pathway for release of this free energy.
Therefore Cs-promoted ordering may be thought of
as approaching nanostructures from a higher-free-en-

may serve to explain both the spontaneous nature of
the reaction and the unprecedented formation of
nanostructures under such mild conditions. Addi-
tional work is underway to uncover the mechanism
of this new nanostructure-forming process.
