What are advanced materials, and are they safe? In this series of seven videos, Risk Bites takes you through the emergence of increasingly advanced materials over the 20th century and the incredible opportunities that these materials and the associated science and technology open up. We'll also be delving into the unique risks that advanced materials potentially raise, and how these might be navigated.
