  1. 1. Dissociative Recombination of Astrochemically Interesting Ions

    Författare :Mathias Hamberg; Wolf Geppert; Mats Larsson; Stephan Schlemmer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dissociative Recombination; Astrochemistry; Chemical physics; Kemisk fysik; kemisk fysik; Chemical Physics;

    Sammanfattning : In this thesis the major work described concerns experimental determination of the dissociative recombination (DR) reaction for several molecular ions of astrochemical interest. DR is the process where an electron recombines with a molecular ion to form an excited neutral that disintegrates into two or more neutral fragments to release the gained excess energy. LÄS MER

  4. 3. Dynamics in the Dissociative Recombination of Small Polyatomic Molecular Ions

    Författare :Vitali Zhaunerchyk; Richard Thomas; Xavier Urbain; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; dissociative recombination; Molecular physics; Molekylfysik; Physics; fysik;

    Sammanfattning : Dissociative recombination (DR) is a process in which a positive molecular ion recombines with an electron and subsequently dissociates into neutral fragments. Among the different types of molecular ion-electron reactions DR deserves particular attention due to the important role it plays in low-temperature and low-density plasmas. LÄS MER

  5. 4. Dissociative Adsorption of CO2 on Copper: The Role of Steps

    Författare :Benjamin Hagman; Synkrotronljusfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; koppar; CO2; Copper surface; Carbon Dioxide : chemistry; Dissociative adsorption; Surface oxidation; Ambient pressure X-ray photoelectron spectroscopy APXPS ; Surface X-ray diffraction SXRD ;

    Sammanfattning : CO2 chemistry has received significant interest in recent time, due to the greenhouse effects of CO2 emissions and the resulting climate change. CO2 reduction reactions, such as methanol synthesis and reverse water-gas shift, is providing a route for recycling of CO2 and thus limiting the CO2 emissions. LÄS MER
