  1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

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

    Author : Grigore-Leon Ratiu; [2024]
    Keywords : Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. READ MORE

  3. 2. Effects of vegetation and nutrients on methanotroph abundance and methane emissions from constructed wetlands

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Klara Yngve; [2022]
    Keywords : Diffusive flux; Ebullition; Dissolved CH4; CH4 oxidation; Phosphorous;

    Abstract : Agriculture is the largest anthropogenic source of nitrogen and phosphorous (P) leakage to Swedish coastal seas, causing eutrophication which threatens marine ecosystems. Constructing wetlands is one way to improve nutrient retention in the modern agricultural landscape. However, constructed wetlands can emit substantial amounts of methane (CH4). READ MORE

  4. 3. An annual evaluation of CH4 oxidation in a freshwater lake

    University essay from Linköpings universitet/Tema Miljöförändring

    Author : Eldina Cehic; [2020]
    Keywords : Methane oxidation; isotopic fractionation; stratification; open steady-state and closed system.; Metanoxidation; isotopfraktionering; stratifiering; öppet stabilt system och stängt system;

    Abstract : Freshwater lakes constrain its methane (CH4) emissions through CH4 oxidation. CH4 includes three carbon (C) isotopes; the stable isotopes 12C,13C and the unstable and more uncommon isotope 14C. Methanotrophs (i.e. READ MORE

  5. 4. Rhizosphere Priming and Methane Oxidation in Agricultural Soil - Effect of Land Use on Atmospheric Concentrations of CO2 and CH4 and Climate Change

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Esben Øster Mortensen; [2017]
    Keywords : The Priming Effect; Rhizosphere; Methane Oxidation; Land Use; Agriculture; Soil Ecology; Microorganisms; Climate Change; Atmospheric concentrations of CO2 and CH4.; Earth and Environmental Sciences; Biology and Life Sciences; Agriculture and Food Sciences;

    Abstract : Rhizosphere interactions have high influence on the fluxes of carbon to and from terrestrial ecosystems. One very important part of the rhizosphere interactions is the rhizosphere priming effect (RPE) which is defined as changes in the decomposition rate of soil organic matter (SOM) in response to labile organic carbon input from plant roots.

  6. 5. Modelling methane emissions from Arctic tundra wetlands : effects of fractional wetland maps

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Zhanzhang Cai; [2014]
    Keywords : fractional wetland maps; Arctic tundra; methane emissions; biogeochemical modelling; Physical Geography and Ecosystem analysis; LPJ-GUESS; sensitivity test; parameter optimization; Earth and Environmental Sciences;

    Abstract : The Arctic tundra has been considered as one of the most sensitive areas to global climate change. One impact of global warming is that permafrost thawing could result in more waterlogged and anaerobic conditions, and consequently an increasing release of methane (CH4) to the atmosphere. READ MORE
