Open Ph.D. position: ?Structure, Stability and Reactivity of
Microhydrated Metal Oxide Clusters?
Applications are invited for an open Ph.D. position in the group of
Prof. Knut Asmis (University of Leipzig, Germany). The work will be
performed at the Free-Electron-Laser facility FHI-FEL at the
Fritz-Haber-Institute in Berlin (Germany). The position is funded by
the German Research Foundation as part of the newly-funded
Collaborative Research Centre 1109 ?Understanding of Metal Oxide/Water
Systems at the Molecular Scale: Structural Evolution, Interfaces, and
Dissolution?.
The goal of the project is to study the structure, stability and
reactivity (towards water) of microhydrated metal oxide clusters using
state-of-the-art mass spectrometric as well as laser spectroscopic
techniques.[1] The clusters are alternatively produced by laser
vaporization, magnetron sputtering or electrospray ionization and
characterized using a cryogenically-cooled ion trap / triple mass
spectrometer setup with direct access to the widely tunable radiation
from the FHI-FEL as well as to a table IR-OPO-OPA laser system. This
custom-built setup allows for IR single- and multiple-photon
photodissociation experiments, as well as the unique opportunity of
performing isomer-specific measurements over nearly the complete IR
spectral range using population labeling spectroscopy
(IR2MS2-technique).[2] Together with quantum chemical calculations
from collaborative groups within the CRC this work is aimed at
shedding new light on the structure-reactivity relationship of metal
oxide aggregates at the molecular level, as well as insights into the
first stages of hydration shell formation at metaloxide-water
interfaces.
We are looking for a highly-motivated, independent candidate with a
Master or Diploma degree in chemistry, physics or a related field.
Prior experience with gas phase clusters, mass
spectrometry and laser spectroscopy, as well as programming skills, is
beneficial. The successful candidate will be based in Berlin, join our
satellite group at the FHI and will be part of the Ph.D.
student training programme MIWOS.
