  1. 6. Ozone oxidation of fatty acid thin films: a TIR Raman study

    University essay from KTH/Yt- och korrosionsvetenskap

    Author : Frida Preuss; [2022]
    Keywords : ozone oxidation; TIR Raman; fatty acid; vibrational spectroscopy; thin film formation; ozonoxidation; TIR Raman; fettsyra; vibrationsspektroskopi; skapande av tunna filmer;

    Abstract : Detta examensarbete initierades och handledes av Mellifiq, ett företag som arbetar med rening av luft och vatten, där en applikation är rening av köksfrånluft med ozon. Ozon förhindrar att fettpartiklar i frånluften ansamlas på väggarna i kanalen och värmeväxlaren, vilket leder till högre brandsäkerhet och mer effektiv användning av värmeväxlaren. READ MORE
