Metal
Oxides
The local
order and crystallinity of a metal
oxide surface is being investigated
with atomic force microscopy and
correlated with the chemical reactivity
of the surface with molecular adsorbates
such as oxygen, water, and methanol
as measured by time-of flight mass
spectroscopy and x-ray photoelectron
spectroscopy. The results of these
studies are relevant to the development
of gas sensors and fuel cell technologies.
Metal
Carbides
The
surface electronic structure of
metal carbides is being measured
with electron spectroscopy and correlated
with the chemical and tribological
properties of the surface.(Tribology
is the study of friction, lubrication,
and wear of two bodies in relative
motion; modern studies have demonstrated
both physical and chemical origins
to these phenomena.) The results
of these studies are relevant to
the development of hard coatings
for use in Aerospace applications.
