Research Group Information

Organic Materials & Interfaces (OMI) is a truly interdisciplinary group sharing common interests in tuning properties of the interfaces via smart chemical modification. Currently, the next projects are running and students can join.

Organic solvent nanofiltration for recovery and re-use of homogeneous catalyst. Ceramic alumina nanofiltration membranes are modified on their surface and inside their pores by well-designed and functionalised polymers to optimise their rejection and permeability properties in molecular separations. The project is sponsored by the Institute for Sustainable Process Technology (ISPT) and Shell.

Understanding surfactant adsorption at sandstone and calcite surfaces. Surfactant adsorption is an important and undesired process in enhanced oil recovery processes. By a combination of Quartz Crystal Microbalance (QCM) measurements and High Temperature High Pressure Atomic Force Microscopy we are investigating these complex systems. The project is sponsored by Shell.

Sodium-selective membranes for application to regenerate green house water. New sodium-selective membranes are designed, synthesized and characterized for use in electrodialysis of green house water. Crown-ether functionalised polymers are made and investigated for this purpose. The project is in close cooperation with Wetsus, European centre of excellence for sustainable water, and Wageningen University

Covalent Organic Frameworks as a tool to make graphite supported metal catalysts for water electrolysis. Covalent Organic Frameworks are 3D-polymers with nano-sized pores and a relative high specific surface area. These systems are hardly investigated for metal salt immobilisation and subsequent pyrolysis. These new materials are investigated for alkaline water electrolysis.

Forensic chemistry and chemical visualizations. The visualisation and isolation of latent forensic traces is a challenge in the field of forensics. In collaboration with the Netherlands Forensic Institute, we investigate and develop novel visualization methods via interface modification.

Synthesis for energy conversion. Great effort is made towards the synthesis of chromophore molecules that can absorb a major part of the solar spectrum. Such molecular assemblies are investigated as interface modifier to induce a photovoltage or to function as super sensitizer in water-splitting catalysis. Redox active polymers and COFs are developed as new electrode materials for advanced Li-ion batteries.
