Originally planned to take place at the Ruhr University Bochum, Germany this two day workshop on November 2 and 3 was quickly transformed into an online event. Various supervisors of PIONEER participated and gave presentations: Vasco Guerra, Xin Tu, Gerard van Rooij and Richard Engeln. But also the ESRs were represented by Chloé Fromentin who talked about “Kinetic mechanisms in CO2 – O2 plasmas: Development of an reaction mechanism”.
