Electricity plays many roles in our lives, from lighting our homes to powering the technology and appliances we rely on every day. Electricity can also have a major impact at the molecular scale, by powering chemical reactions that generate useful products. Working at that molecular level, MIT chemistry professor Yogesh Surendranath harnesses electricity to rearrange chemical bonds. The electrochemical reactions he is developing hold potential for process such as splitting water into hydrogen fuel, creating more efficient fuel cells, and converting waste products like carbon dioxide into useful fuels. “All…
