The general objective of the three-year project “SNISMs” funded by the DFG, which is being carried out in collaboration with TU Dortmund, is the understanding and knowledge-driven predictive development of acid-catalysed reactions in strongly non-ideal solvent mixtures (SNISMs) with respect to catalyst activity and dissociation, phase behaviour, reaction kinetics and reaction equilibrium. A thermodynamic screening tool will be implemented that allows ranking strongly non-ideal solvent mixtures (SNISMs) on the phase behavior, upstream (thermodynamics and kinetics of reactions) and downstream processing (product purification and catalyst recycling). The model will be validated with catalytic experiments using the most efficient heteropolyacid (HPA) catalyst providing a high acidity and hydrolytic stability for selected esterification reactions. Thus, the focus will be on sustainability by using catalysts and novel solvent mixtures, with a focus on biodegradable, cheap, and thus sustainable components. Moreover, the goal is to establish a fundamental understanding of the interactions between the SNISMs (and their constituents) and HPA catalysts for the kinetics of the selected reactions, and we aim at elucidating the additive influence of SNISM constituents on kinetics. Further, the accuracy of the ePCSAFT predictions for the phase behaviour and for the SNISMs influence on reaction kinetics, reaction equilibrium and catalyst activity and dissociation equilibrium will be determined.

The Project PalMod Phase III is a project between Universität Hamburg and several other German research institutes and universities, funded by the Federal Ministry of Education and Science (BMBF), to understand Earth system dynamics and variability during the last glacial cycle.

Model simulations in PalMod Phase II with cryosphere-ocean-atmosphere interactions in MPI-ESM have captured some features of the abrupt events of the last deglaciation (Heinrich events, Bølling-Allerød warming, Younger Dryas). Studies of marine sediments show that such abrupt events profoundly affect ocean biogeochemistry. Nevertheless, the cascades of changes in oceanic biogeochemistry have not yet been examined using comprehensive Earth system models with interactive carbon cycle. The planned work will address this knowledge gap. The project will focus on examining the response of the ocean carbon storage and biogeochemical cycles to abrupt events in MPI-ESM projections spanning the last deglaciation and future climate change scenarios with the goal to improve our quantitative understanding of the observed cascades of change.

Duties include academic services in the project named above. Research associates may also pursue independent research and further academic qualifications.

The activity includes the scientific collaboration in the third party funded project “FIIPS@Home” (An Early Warning, Information and Intrusion Prevention System for the Security of Private Home Networks). The focus is on the development of a collaborative and privacy-friendly platform for the detection and defense of attacks on private IT infrastructure. Together with other project partners, this platform will be designed, implemented, analyzed and evaluated. In addition, the position holder will continuously contribute to the publication and presentation of research and project results. As a research-intensive department, our research results are also directly incorporated into teaching.

The overall goal of the PrimePrevention collaborative project is to develop a coordinated strategy among German coastal countries to address the societal challenges related to increasing marine natural hazards due to climate change. Among those hazards are upwelling events, during which oxygen-depleted (hypoxic) and sulfidic deep-water is transported to the sea surface. These events occur regularly in late summer, especially on the east coast of Schleswig-Holstein, and not only affect the general health of the coastal ecosystem, but also the regional economy.

The goal of the project will be to gain an improved understanding of the sediment biogeochemical processes, which cause the release of hydrogen sulfide from the sediment into the water column. The new findings will be used in collaboration with microbiologists and physical oceanographers to predict and map the likelihood for the occurrence of sulfidic upwelling events in Kiel Bight and to evaluate the associated risk for local stakeholders (fishery, aquaculture, tourism). The research methodology applied will include sampling campaigns at sea, laboratory analyses and numerical reaction-transport-modeling. The project provides the opportunity to work on a timely geoscientific research topic with environmental and societal relevance.
