Lennart Joos presented his PhD research on the TEDx Ghent auditions and was selected as a speaker for the TEDx meeting in June 22. In a six-minute talk, he demonstrated how a superacid has the potential to remove the hazardous NOx from exhaust gasses and hence prevent the formation of smog. Computer simulations provided a unique insight into the chemistry of this absorption process. In June, he will be speaking in front of 1000 knowledge junkies at TEDx Ghent!
