Dear Colleague
I would appreciate it if you would pass the following postdoctoral position
announcements on to any students who might be interested. The areas are:
1. Surface Chemistry: Size-Selected Model Catalysts/Cluster-Surface
Deposition Dynamics
For this position, a background in surface chemistry/surface science
techniques is desirable, but good candidates in other areas will be
considered.
2. High Energy Fuels: Metal NanoClusters as Combined Fuel and Combustion
Catalyst
For this position, a background in kinetics or catalysis is desirable, but
good candidates in other areas will be considered.
More complete descriptions are given below
regards

Postdoctoral Positions in Surface Chemistry and High Energy Fuels Chemistry
Two postdoctoral positions are available in the lab of Professor Scott
Anderson, in the Chemistry Department of the University of Utah. A short
description of each position follows. Additional information can be
obtained from my web site
(www.chem.utah.edu/chemistry/faculty/anderson/anderson.html) or by e-mailing
me at ([log in to unmask]). Both positions offer competitive salaries
and excellent health benefits. If interested, please send a CV and arrange
to have three letters of recommendation (include PhD advisor and any
postdoctoral mentors) sent to Prof. Scott Anderson, Dept. of Chemistry,
University of Utah, 315 S. 1400 E. Rm 2020, Salt Lake City, UT 84112. The
University of Utah is an EEO employer and encourages applications from
qualified minorities and women.
Surface Chemistry: Size-Selected Model Catalysts/Cluster-Surface Deposition
Dynamics
Mass-selected metal clusters are deposited on planar oxide supports, then
characterized by a combination of in situ XPS, ISS, AES, and TPD/R. STM is
also available but not in situ, and we are hoping to add in situ IR
spectroscopy this year. We are interested in both the chemical properties
of the model catalysts produced by cluster deposition, and also in the
dynamics of the cluster-support interaction. Issues of particular interest
are the effects of cluster size, impact energy, and of different types and
densities of support defects. Recent results on Ni clusters and Ir clusters
on TiO2 are available at
http://www.chem.utah.edu/chemistry/faculty/anderson/clussurf.html.
For this position, a background in surface chemistry/surface science
techniques is desirable, but good candidates in other areas will be
considered.
High Energy Fuels: Metal NanoClusters as Combined Fuel and Combustion
Catalyst
Micron sized metal (aluminum, sometimes boron) particles are commonly added
to propellants as a high energy density fuel. Particles can also be added
to liquid hydrocarbon fuels to produce a slurry with higher energy density
that could be obtained with hydrocarbon fuels alone. As the particle size
decreases, the surface area per volume increases, so that eventually the
molecule-surface collision frequency begins to compete with intermolecular
collisions. In this limit, catalytic surface chemistry, even if not very
efficient, can begin to contribute significantly to combustion rates. In
this project we will explore the possibilities for enhancing combustion
rates by introducing high surface area particles. One particle type of
interest is pure metal coated with a native oxide (e.g. Al/Al2O3), where the
oxide may serve as a catalyst. The particle surfaces can also be doped with
small amounts of more catalytically active metals, or with active oxides,
such as ceria. To avoid the complications inherent in real fuels, which are
complex mixtures, we will focus on breakdown of JP10 (a synthetic fuel) and
other pure hydrocarbon species. Breakdown is monitored on-line by in situ
mass spectrometry.
For this position, a background in kinetics or catalysis is desirable, but
good candidates in other areas will be considered.
