Professor Bowen's research interests
are centered around clusters and nanoparticles. Clusters
are aggregates of atoms and/or molecules held together by
some of the same interatomic or intermolecular forces
which are responsible for cohesion in solids and liquids.
Clusters are thus finite-size microcosms of the condensed
phase, the realm in which most chemistry occurs. A major
objective of Dr. Bowen's research is to provide a
molecule's eye view of many-body, condensed phase
interactions. The study of size-specific and
composition-specific clusters provides an incisive means
of addressing this fundamental and longstanding problem
in physical chemistry. For technical reasons, clusters
are best studied as negatively-charged species.
Experimental methods utilized in Dr. Bowen's group to
study clusters include both continuous and pulsed
negative ion photoelectron spectroscopy, mass
spectrometry, and photodissociation spectroscopy. This
work is instrumentally oriented, with major components of
their several ion beam apparatus including both
continuous and pulsed lasers, high vacuum systems, ion
and electron optics, electronics and computers, as well
as time-of-flight, quadrupole, magnetic sector, and Wien
fliter mass spectrometers. The training in advanced
instrumentation, afforded students in Dr. Bowen's group,
lays a firm foundation for careers in either physical or
analytical chemistry. Experimental emphasis is also
placed on designing unique sources of cluster ions and on
the preparation and characterization of nanoparticles for
a variety of technological applications, such as
catalysis. |
