  1. 21. A model for heterogenic catalytic conversion of carbon dioxide to methanol

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Elin Johannesson; [2020]
    Nyckelord :Carbon dioxide; methanol; heterogeneous catalysis; zinc oxide; computational chemistry; density functional theory;

    Sammanfattning : Since our society became industrialised, the levels of carbon dioxide in our atmosphere have been steadily rising, to the point where it in early 2020 at is 413 ppm. The high concentration is causing several troubling effects worldwide because of the increase in mean temperature that it creates, which causes longer draughts, more severe floods, and rising seawater levels to name a few.

  5. 24. Swedish wetlands and their role in helping Sweden reach domestic climate neutrality by 2045

    Kandidat-uppsats, Stockholms universitet/Institutionen för naturgeografi

    Författare :Niki Giarimi; [2020]
    Nyckelord :;

    Sammanfattning : Wetlands are among the most productive ecosystems on earth, in particular when it comes to long- term storage of carbon. Their unique conditions of saturated soils and vegetation cover have resulted in them playing an important role in the regulation of atmospheric greenhouse gases such as carbon dioxide and methane.
