PFAS show up in products as varied as firefighting foams, nonstick cookware and stain-resistant fabrics. While none of the proposed substitutes outperform existing PFAS yet, the best alternatives are approaching the same performance in certain water-repelling applications, scientists report in the July 15 Journal of Colloid and Interface Science.” …
