The remaining years of our ending millennium are characterized by a
tempestuous devel- opment of Surface Science, whose ultimate
consequences are presently hard to foresee. While some of these
consequenees are apparent to everybody (e. g. modern information
eleetronies would hardly be possible without the progress in device
fabrication whieh, in turn, has required profound knowledge of surface
teehnology ) there are several other dis- ciplines where the impact of
surface physical chemistry may not be so obvious, but, nevertheless, has
contributed much to the technological progress made in the past, and is
expected to cause even more such benefit in the future. We only list
here the c1assical syn- thetic inorganic chemistry or the technical
chemistry which have both greatly benefited from a more fundamental
understanding of heterogeneously catalyzed (surface) pro- cesses leading
to, among others, improved industrial fabrication processes. (We selec-
tively mention the promising attempts to model the Fischer-Tropseh
reaction or the ammonia synthesis reaction, remembering also the
optimization of the hydrocarbon reforming proeess by developing
appropriate bi metallic catalyst materials). Furthermore, materials
science with its considerations of eorrosion, embrittlement, and
fracture, as weIl as energy technology with its considerations of
photovoltaics, hydrogen storage, or fuel cell development, must also be
mentioned here. Many other important aspeets remain unmentioned, because
of space limitations.
