This Project Grant award for $420,000.00, provided by the National Science Foundation (NSF) under the Engineering program (CFDA 47.041), will develop a novel photochemical system to degrade per- and polyfluoroalkyl substances (PFAS) in water. The research aims to (1) investigate the working mechanisms of the new reaction system, (2) examine its performance in degrading various PFAS, (3) characterize PFAS degradation pathways and products, and (4) evaluate and improve the system's performance...
This Project Grant award from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) provides $150,000 to Claremont McKenna College to discover enzymatic pathways to break carbon-fluorine bonds in perfluorinated carboxylic acids (PFAS). PFAS are a group of persistent chemicals that are costly to remove from the environment. The project aims to engineer special enzymes that can degrade these stable chemical bonds, which could unlock new technologies for PFAS remediation in...
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 National Science Foundation (NSF) EAGER (Early-Concept Grants for Exploratory Research) project grant, awarded under the NSF Engineering program (CFDA 47.041), focuses on developing new fundamental understanding and early-stage technology for energy- and cost-effective aqueous defluorination of per- and polyfluoroalkyl substances (PFAS) using sustainable solar-assisted electrocatalysis. The $299,987 award, effective July 1, 2024 through June 30, 2026, will support research at the University...
This $419,463 Project Grant award from the National Science Foundation's Engineering program (CFDA 47.041) will support research by Georgia Tech Research Corporation to investigate enhanced electrochemical oxidation methods for the destruction of per- and polyfluoroalkyl substances (PFAS) in water. The project aims to systematically study the influence of electric field strength on PFAS electromigration and oxidative degradation, leveraging locally enhanced electric field treatment (LEEFT) to...
This Project Grant award of $350,000 from the National Science Foundation's Engineering program (CFDA 47.041) supports a collaborative research project at the University of Missouri System (Missouri S&T) to discover enzymatic pathways that can break carbon-fluorine bonds in perfluorinated carboxylic acids (PFAS). PFAS are a group of costly-to-remove chemicals that do not naturally break down in the environment due to their strong carbon-fluorine bonds. The goal of this 3-year project is to...
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...
The National Science Foundation (NSF) awarded a $227,460 Project Grant under its Engineering program (CFDA 47.041) to Arizona State University (ASU) to conduct collaborative research on elucidating nanofiltration removal performance and mechanisms for short-chain per- and polyfluoroalkyl substances (PFAS). This 3-year project, which commenced on September 1, 2024, aims to address critical knowledge gaps in the effectiveness of nanofiltration for removing diverse PFAS types, especially...
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...
