This $255,638 Project Grant award from the National Science Foundation's Engineering program (CFDA 47.041) will support a collaborative research project to elucidate the role of ion dehydration in regulating the transport and selectivity of monovalent ions in polyamide nanofiltration (NF) membranes. The overarching goal is to explore a novel ion dehydration mechanism that can enable challenging separations, such as the extraction of lithium from brines, beyond the capabilities of current NF...
This $300,000 Project Grant award from the National Science Foundation's (NSF) Division of Materials Research supports research at Northwestern University aimed at improving the understanding of ion transport in spatially-confined, electrically-charged environments. The research focuses on developing theoretical, numerical, and computational approaches to design and analyze both externally driven and surface-induced ionic flows in confined systems, with an emphasis on understanding the roles...
This $450,000 National Science Foundation project grant will fund research into ion transport and selectivity in salt-rejecting polymer membranes operating under elevated salinities and pressures. The grant was awarded on August 1, 2022 to The Regents of the University of Colorado, with completion scheduled for July 31, 2025. The project aims to investigate using polymer membranes to treat extremely salty wastewaters from desalination and oil/gas production in a way that uses less than 10% of...
This three-year, $349,991 Project Grant from the National Science Foundation's Engineering program (CFDA 47.041) will fund research at Columbia University to develop dual-driving force operation of ion-selective membranes for selective ion separation. The Principal Investigator will work to enhance membrane selectivity and permselectivity by coordinating two opposing driving forces—electrostatic potential and hydraulic pressurization—during transport. Specific objectives include developing a...
