Plastics focused on recyclability from the beginning. The result is a new kind of plastic called polydiketoenamine or PDK

A report on PDKs has been published recently in the journal Nature Chemistry. “With PDKs, the immutable bonds of conventional plastics are replaced with reversible bonds that allow the plastic to be recycled more effectively.”  Unlike conventional plastics, the monomers of PDK plastic can be recovered and freed from any additives simply by dunking the material in a highly acidic solution. The acid …

Biomimicry: New Platform Adapting Natural Processes Lets Surfaces Self-Clean

Aruga Technologies, a Pennsylvania start-up, has developed a technology platform that allows surfaces to self-wipe and remain continuously clean throughout contact with depositing fluids. The technology is inspired by how some natural surfaces, such as arteries, dolphin skin, and mussel use dynamic surface wrinkles to renew. Mimicking this phenomenon in synthetic surfaces decreases fouling and results in an optimized and …
