The aliphatic polycarbonates created by Cornell chemist Geoffrey Coates are safe and strong enough to be used in medical implants and devices. They're also used as extremely effective binders for the creation of non-oxide ceramics, which are often used as components experiencing high compressive stresses such as cam rollers in diesel engines, valves, seals, rotating parts and wear plates, abrasive powder blast nozzles, cutting tool tips, and more.
