{"id":"https://openalex.org/G7746357313","display_name":"Enhancing transport and delivery of ferrihydrite nanoparticles via polymer encapsulation in PFAS-contaminated sediments to simulate PFAS defluorination by Acidimicrobium sp. Strain A6","description":"Project Narrative Per- and polyfluoroalkyl substances (PFAS), especially perfluorooctanoic acid (PFOA) and perfluoro octane sulfonate (PFOS), have been associated with multiple health problems and are being detected with increasing frequency in ground and drinking water sources. PFAS, and especially the perfluorinated ones like PFOA and PFOS, are considered to be stable and not biodegradable. Here we propose a novel method that leverages the only known organism to date that can defluorinate PFAS to allow for the design and operation of bioremediation schemes at sites with these contaminants, resulting in the detoxification of the affected water resources.","funder_award_id":"R01ES032694","funder":{"id":"https://openalex.org/F4320337361","display_name":"National Institute of Environmental Health Sciences","doi":"10.13039/100000066"},"funded_outputs":["https://openalex.org/W4384069875","https://openalex.org/W4391852938","https://openalex.org/W4400693245","https://openalex.org/W7147225054","https://openalex.org/W7166710767"],"funded_outputs_count":5,"parent_awards":[],"sub_awards":[],"sub_awards_count":0,"amount":null,"currency":"USD","amount_usd":null,"amount_usd_basis":null,"recipients":[],"recipient_countries":[],"recipient_regions":[],"research_scope":{"is_research":true,"basis":"funder_default","tier":1},"funding_type":"research","funder_scheme":"R01","start_date":"2021-02-16","end_date":"2024-10-31","start_year":2021,"end_year":2024,"landing_page_url":"https://reporter.nih.gov/project-details/10515660","doi":null,"provenance":"nih_exporter","lead_investigator":{"given_name":"PETER R.","family_name":"JAFFE","orcid":null,"role_start":null,"affiliation":{"name":"PRINCETON UNIVERSITY","country":"UNITED STATES","ids":null}},"co_lead_investigator":null,"investigators":null,"works_api_url":"https://api.openalex.org/works?filter=awards.id:G7746357313","primary_topic":{"id":"https://openalex.org/T11869","display_name":"Per- and polyfluoroalkyl substances research","score":0.9855,"subfield":{"id":"https://openalex.org/subfields/2304","display_name":"Environmental Chemistry"},"field":{"id":"https://openalex.org/fields/23","display_name":"Environmental Science"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}},"topics":[{"id":"https://openalex.org/T11869","display_name":"Per- and polyfluoroalkyl substances research","score":0.9855,"subfield":{"id":"https://openalex.org/subfields/2304","display_name":"Environmental Chemistry"},"field":{"id":"https://openalex.org/fields/23","display_name":"Environmental Science"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}}],"institution_awarded":[{"id":"https://openalex.org/I20089843","display_name":"Princeton University","ror":"https://ror.org/00hx57361","country_code":"US","type":"education","lineage":["https://openalex.org/I20089843"]}],"updated_date":"2026-10-30T03:00:55.000Z","created_date":"2026-10-09T19:56:01.000Z"}
