The National Science Foundation (NSF) awarded a $437,610 Project Grant under the Engineering program (CFDA 47.041) to the University of Cincinnati to research the mechanisms for the release of nanoparticles from automotive tire tread. The project aims to explore how nanoscale tire wear particles are released into the environment, as tire wear is a major source of unregulated microplastic pollution. Through close collaboration between industry, government, and academia, the research will study the interfacial charging mechanism driving nanoparticle release and develop new approaches to mitigate these emissions. The project also plans to engage high school students in sample collection and public education on the issue of nanoparticle and microplastic environmental exposure from tires. The award period is from May 1, 2024 to April 30, 2027, and subawards are planned as part of this effort.
