  1. 21. Linking the selectivity of varying surface phases of a real palladium catalyst toward specific methane oxidation pathways with Ambient Pressure X-ray Photoelectron Spectroscopy

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Author : Ulrike Küst; [2023]
    Keywords : APXPS; catalysis; palladium; methane; Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis, especially within methane oxidation, is of high importance in order to more efficiently remove unburned methane from bio-fuel exhausts. This is relevant as bio-fuel engines will replace those driven by fossil fuels in the coming decades. READ MORE

  3. 22. Effects of clear-cut logging on five old-growth forest bryophyte species. : How does the most common forestry method in Sweden impact vulnerable forest specialists?

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Nathalie Edwards; [2023]
    Keywords : Bryophytes; old-growth forests; forestry; nature conservation; sustainable forestry; mossor; gammelskog; skogsbruk; naturvård; hållbart skogsbruk;

    Abstract : Clear-cut logging is the most widely practised forestry method in Sweden. This often conflicts with nature conservation and leads to issues where economic interests are pitted against ecological values. READ MORE

  4. 23. Quantity and quality of oaks (Quercus) as suitable habitats for the longhorn beetle species Plagionotus detritus : An inventory study in Stockholm and Uppsala County, Sweden

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning
