Biorefinery [SORT] Molecular Methods for Separation Processes [SORT] Nanoporous Materials [SORT]
The Biorefinery group focuses on converting lignocellulosic biomass into high-value products using CO₂, water, and enzymes. It aims to fully utilize plant residues like wheat straw, isolating components such as cellulose, hemicellulose, and lignin for bio-based chemicals, fuels, and materials. The group supports the second-generation biorefinery concept and participates in outreach activities like the European Summer School in High Pressure Technology. The Molecular Methods for Separation Processes group develops predictive models for designing and optimizing innovative separation processes, especially in complex electrolyte and solvent systems. Key efforts include advancing COSMO-RS-ES and COSMO-RS-Phi for modeling electrolytes, investigating enzyme behavior, and exploring stimuli-responsive gels for autonomous process control using both experimental and theoretical approaches. The Nanoporous Materials group explores the synthesis, characterization, and scalable processing of aerogels using supercritical CO₂ drying. Research includes biopolymer-based aerogels for biomedical and food applications, renewable precursors like lignin, and emulsion gelation for sub-100 µm particles. The group also applies modeling to optimize processes like drying and solvent exchange, with a focus on industrial integration.

Current Projects

SMART Reactors

The DFG Collaborative Research Center CRC 1615 SMART Reactors develops flexible, self-adapting reactor systems through fundamental research. These SMART reactors aim to sustainably convert renewable resources into multiple products, enabling resilient and scalable processes.

 

PintPFS

The Research Training Group ‘Processes in Natural and Technical Particle-Fluid Systems’ (PintPFS) brings together civil, materials, mechanical, and process engineering to study, and improve particle-fluid systems. Advanced measurement tools, strong partnerships (e.g. DESY, Hereon), and a structured training program support cutting-edge doctoral research.

 

KNIFFELIX

Together with the wonderful people at KNIFFELIX, we design engaging riddles and hands-on exercises that introduce young people, and anyone curious about science and technology, from ages 8 to 99, to the fascinating world of aerogels. These playful learning formats make complex topics more accessible and spark curiosity about advanced materials.
