Systems and Methods for Degrading PFAS
Background Per- and polyfluoroalkyl substances (PFAS) are widely used, hard-to-break-down chemicals that are harmful to human health; they contaminate water, soil, animals, and people all over the world. PFAS removal from the environment is thus very challenging, and effective PFAS remediation is so urgently needed that the U.S. government recently...

Shape Memory Polymers
Technology Overview A class of shape memory polymers with the unique property that the shape recovery rate is adjustable. The polymers can be structurally tailored to fit many applications because the rate of strain relaxation is influenced by the number and type of covalent cross-links, non-covalent hydrogen bonds, and temperature. Benefits Shape...
