20. The Haber-Bosch process, devised in the early 20th century, revolutionized global industry. It provides a way of“fixing” atmospheric nitrogen into ammonia, allowing for the production of fertilizers and the many nitrogenbased chemicals we use today. The reaction is carried out in numerous industrial facilities all over the world:
