This $255,638 Project Grant award from the National Science Foundation (NSF) Engineering program (CFDA 47.041) will fund a collaborative research effort to study the role of ion dehydration in regulating the transport and selectivity of monovalent ions in polyamide nanofiltration (NF) membranes. The award, with a performance period from September 1, 2024 to August 31, 2027, involves researchers from the University of Wisconsin - Madison and the Technion - Israel Institute of Technology. The key objectives are to:
- Investigate the impact of ion dehydration on the transport and selectivity of ions in state-of-the-art NF membranes.
- Analyze the effects of membrane surface hydrophobicity and charge on ion dehydration using custom-fabricated NF membranes.
- Employ molecular dynamics simulations to support the experimental results on ion dehydration and membrane selectivity.
The project aims to advance the understanding of NF separation mechanisms to address critical societal needs around water purification, desalination, and resource recovery. It will also include outreach activities to increase scientific literacy and awareness around water sustainability.
