The broader impact/commercial potential of this I-Corps project is the development of technology that will provide access to clean water. This project will generate knowledge to develop efficient, cost-effective and sustainable per- and polyfluoroalkyl substance treatment technologies, help the water industry and industry dischargers, prepare our society for water sustainability, and ultimately protect public health. The customers for the technologies include the industrial wastewater dischargers, hazardous waste site managers, municipal water districts, private water companies, chemical manufacturing industries, and government agencies. This project will enhance US technological competitiveness in the water sector by accelerating new knowledge transfer.This I-Corps project is based on the development of a vacuum ultraviolet light-driven photochemical technology for treatment of per- and polyfluoroalkyl substances. This technology is a clean and energy-efficient medium that directly photolyzes water to a pool of energetic radicals. The traditional application of this system for per- and polyfluoroalkyl substance treatment is limited by an unreactive environment (i.e., simultaneous generation of oxidative and reductive radicals) and low quantum yield of radicals. This project will develop an innovative system that overcomes the deficiencies, and elucidate the unique mechanism for generation, propagation, and manipulation of reactive radicals for a complete destruction of per- and polyfluoroalkyl substances.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

I-Corps项目的更广泛影响/商业潜力是开发提供清洁水的技术。该项目将产生知识，以开发高效、具有成本效益和可持续的单氟烷基和多氟烷基物质处理技术，帮助水工业和工业排放者，使我们的社会为水的可持续性做好准备，并最终保护公众健康。该技术的客户包括工业废水排放者、危险废物场地管理者、市政水区、私营水务公司、化学制造行业和政府机构。该项目将通过加速新知识的转移，提高美国在水务部门的技术竞争力。这个I-Corps项目的基础是开发用于处理全氟烷基和多氟烷基物质的真空紫外光驱动光化学技术。这项技术是一种清洁和节能的介质，直接将水光解成一池高能自由基。该系统用于处理全氟烷基和多氟烷基物质的传统应用受到非反应环境（即氧化自由基和还原自由基同时产生）和自由基量子产率低的限制。本项目将开发一种创新的系统，以克服这些不足，并阐明活性自由基的产生、传播和操纵的独特机制，以完全破坏全氟烷基和多氟烷基物质。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
