On September 1, 2022, Frédérique Battin-Leclerc (LRGP) received the Polanyi Medal, named in honor of Michal Polanyi. This biennial prize of the Royal Society of Chemistry has been awarded since 1979; previous winners include John Polanyi, Nobel Prize in 1986, and Mario Molina, Nobel Prize in 2012. Until 2022, there was only one female laureate (2018) and no French. This prize rewards outstanding contributions to the field of gas kinetics. The presentation was followed by a plenary lecture by the laureate entitled “Chemistry of fuel low-temperature oxidation: recent progress and open questions”.
