With the help of scientists like Sophia Hayes, associate professor of chemistry, new technologies may make it possible to remove the greenhouse gas carbon dioxide from the atmosphere, turn it into a solid, and store it in a safe environment elsewhere. Hayes uses a technique called nuclear magnetic resonance (NMR) to understand the structure of materials, including carbon dioxide. Hear her describe this research project, explain how NMR works, and reveal how “the magic angle” – a Washington University innovation – changed the field.
