Day 22 of the chemistry advent timeline first looks at the discoverer of another allotrope of carbon: Sumio Iijima is a physicist who discovered carbon nanotubes. They have since been used in a number of applications, with research looking into further possibilities.

Frances Arnold is a biochemist who uses ‘directed evolution’ to optimise enzymes for a variety of processes. She shared the 2018 Nobel Prize in Chemistry for her work. 

Jacqueline Barton carries out work on electron transport in DNA. Her work has potential applications in disease diagnosis and treatment. In 2015, she won the American Chemical Society’s highest honour, the Priestley Medal, for her work.
