The project aims to create supracolloidal membrane structures inspired by the...
This $199,999 federal Project Grant award from the National Science Foundation's Engineering program (CFDA 47.041) will fund research to elucidate the performance and mechanisms of nanofiltration (NF) for removing short-chain per- and polyfluoroalkyl substances (PFAS) from contaminated water. The research aims to evaluate NF removal of diverse (ultra)short-chain PFAS, establish structure-property-performance relationships using machine learning, and investigate PFAS interactions with NF...
This National Science Foundation (NSF) Project Grant award, under the NSF Directorate for Engineering (CFDA 47.041), will provide $212,973 to the University of Utah from July 2023 to June 2026 to conduct collaborative research on the molecular and nanoscale structure and interactions of per- and polyfluoroalkyl substances (PFAS), also known as "forever chemicals." The research will investigate PFAS surfactants in aqueous solutions and at water-air, water-oil, and water-solid...
This two-year, $194,025 Project Grant from the National Science Foundation's Division of Chemical, Bioengineering, Environmental, and Transport Systems will fund the development of a low-cost, mass-scale sorbent for removing toxic per- and polyfluoroalkyl substances (PFAS) from drinking water. Montclair State University will design a fluorinated block copolymer sorbent that leverages self-assembly at solid-liquid interfaces to facilitate PFAS elimination. The porous polymer will be synthesized...
The National Science Foundation (NSF) Division of Chemical, Bioengineering, Environmental, and Transport Systems awarded a $301,130 project grant to The Research Foundation for the State University of New York (SUNY) to study the molecular and nanoscale structure and interactions of per- and polyfluoroalkyl substances (PFAS) in aqueous solutions, at interfaces, and with other surfactants. The research aims to develop fundamental knowledge that supports improved water quality and the design of...
This Project Grant award from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) provides $200,000 to Georgia Tech Research Corp to conduct research on the use of nanofiltration (NF) for removing short-chain per- and polyfluoroalkyl substances (PFAS) from contaminated water. The overarching goal is to elucidate the performance and mechanisms of (ultra)short-chain PFAS removal by NF through an integrated approach of experimental studies and computational modeling, including...
This National Science Foundation (NSF) Engineering program (CFDA 47.041) project grant, awarded to Arizona State University for $227,460, aims to elucidate the performance and mechanisms of nanofiltration (NF) for removing (ultra)short-chain per- and polyfluoroalkyl substances (PFAS) from contaminated water. The 3-year project, starting Sep 1, 2024, will combine experimental studies and computational modeling to investigate NF's effectiveness in removing diverse PFAS, especially short-chain...
This $477,596 federal Project Grant awarded by the National Science Foundation's Division of Chemical, Bioengineering, Environmental, and Transport Systems (CFDA 47.041 - Engineering) to the University of Alabama supports research to improve the selectivity of polyamide reverse osmosis (PARO) membranes for seawater desalination. The project will use a combined computational-experimental approach to investigate how surfactant molecular structure affects the interfacial polymerization process...
This $386,034 National Science Foundation project grant supports the development of chemically resilient, fouling resistant polymer membranes for water separation applications. Funded under the Engineering program (CFDA 47.041), the 24-month award to the University of Massachusetts Amherst enables fundamental research to manufacture porous polymer membranes using an all-aqueous process that eliminates toxic solvents currently used. The research aims to (1) develop a mechanistic understanding...
