Researchers at Penn and Argonne National Laboratory have made the most direct observation of a key intermediate, a carbon-centered radical, formed during the breakdown of hydrocarbons during combustion and in the atmosphere. This benchmark study could help researchers design fuels that burn more efficiently in the future.
