Please note the following offer for a PhD position:


Partitioning of organic compounds between gas and particle phase in atmospheric aerosol

PhD at IEK-8: Troposphere, FZ-Jülich


With 4400 staff members Forschungszentrum Jülich is the largest interdisciplinary research center in Germany focusing its research in the fields of health, environment and energy, and information technology. At IEK-8: Troposphere simulation chamber experiments, experimental field studies, and model calculations are used to investigate the processes that control the chemical transformation and spatial distribution of trace compounds, and their ultimate removal from the atmosphere. About 60 scientists, engineers, technicians, and doctoral students are currently working at the institute in the field of atmospheric chemistry. The distribution of semi- and low volatile organic species between the gas and particle phase is usually described by the partitioning coefficient, assuming equilibrium conditions. Recent findings indicate that the observed organic particle mass in the field is larger than can be explained based on current understanding. We therefore perform dedicated measurements of the partitioning coefficient in simulation chamber experiments to understand the distribution of organic compounds between gas and particle phase.


Job description


We have an immediate opening for a PhD student focusing on the determination of partitioning coefficients for key organic substances of low and intermediate volatility. The candidate will determine partitioning coefficients experimentally using mass spectrometric methods developed at the institute. Comparisons with model predictions of the partitioning coefficient based on vapor pressure estimates will be used to challenge current theories of organic aerosol formation.
