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 $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...
The National Science Foundation (NSF) awarded a $221,627 Project Grant under its Engineering program (CFDA 47.041) to the Regents of the University of Minnesota to conduct research on the transformation mechanisms and products of per- and polyfluoroalkyl substances (PFAS) during drinking water disinfection processes. The 3-year project, beginning August 1, 2024, will investigate how PFAS compounds react with common disinfectants like chlorine and ozone. This research aims to improve...
The National Science Foundation (NSF) awarded a $499,997 Project Grant under the Engineering program (CFDA 47.041) to the Regents of the University of Michigan to fund research aimed at advancing the use of persulfate and powdered activated carbon for in situ capture and destruction of per- and polyfluoroalkyl substances (PFAS) contaminating groundwater. The 3-year project will: 1) evaluate reaction kinetics for PFAS degradation using the persulfate/activated carbon treatment process, 2)...
This Project Grant from the National Science Foundation Division of Chemical, Bioengineering, Environmental, and Transport Systems Engineering Directorate provides $419,999 to Rice University from October 1, 2022 to August 31, 2025. The funding supports research to develop synthetic membranes for filtering per- and polyfluoroalkyl substances (PFAS) from water to below 70 parts-per-trillion, as well as education and training. Specifically, the awardee will design recognition sites for anionic...
This Project Grant award of $412,000 from the National Science Foundation (NSF) Engineering program (CFDA 47.041) will be used by the University of Massachusetts (UMass) to investigate the use of engineered polymer microparticles to adsorb and remove per- and polyfluoroalkyl substances (PFAS) from wastewater. The central hypothesis is that the adsorption of PFAS molecules will alter the interfacial properties of the microparticles, causing emulsions to destabilize and allowing for the capture...
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 National Science Foundation Project Grant of $312,596 awarded on October 1, 2022 will support research at San Diego State University to develop an innovative "trap and destroy" water treatment technology for per- and polyfluoroalkyl substances (PFAS). The university will work to optimize adsorptive photocatalysts that can selectively absorb PFAS from water and then destroy the compounds using ultraviolet or solar light. Key deliverables under the 24-month award include...
This National Science Foundation (NSF) Project Grant award under CFDA 47.041, Engineering, provides $241,750 to the University of Missouri System to research the transformation mechanisms and products of per- and polyfluoroalkyl substances (PFAS) during water disinfection processes. The 3-year project, running from August 2024 to July 2027, aims to determine how PFAS and their precursors react with common disinfectants like chlorine and ozone during drinking water treatment. The research...
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...
