In summary, we investigate interfacial atmospheric
reactions along four lines of research:
- Experimental measurement of the interfacial kinetics
on model substrates using a Knudsen flow reactor
or a molecular diffusion tube
- Experimental measurement of heterogeneous chemistry
in the presence of laboratory-generated aerosols
under well-defined conditions of size-distribution and
gas phase composition. Aerosol characterization studies
- Multiple diagnostic experiment using a stirred
flow reactor to investigate both the gas and the
condensed phase (FTIR, mass spectrometry, quarz crystal
microbalance...)
- Box-model simulations of the effect of heterogeneous
reactions on atmospheric chemistry
- Chemical kinetics and mechanismus of
interfacial reaction on substrates of atmospheric interest
and other technologically important materials.
- Time-resolved and steady state measurements
in Knudsen flow reactors using mass spectrometric and
laser-based analytical techniques.
- Measurements of surface residence times
of non-reacting and reacting molecules under the constraint
of saturable surfaces.
- Physico-chemical characterization of
laboratory-generated aerosols.
- Characterization of surface species
using FTIR spectroscopy after contamination of water
ice by different trace gases under atmospheric relevant
conditions.
- Box model calculations addressing a
realistic description of heterogeneous chemistry under
upper tropospheric and lower stratospheric conditions.
- Chemical-kinetic modeling of interfacial
reaction mechanismus.
