1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/SynkrotronljusfysikSammanfattning : 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. LÄS MER
2. Effects of vegetation and nutrients on methanotroph abundance and methane emissions from constructed wetlands
Master-uppsats, SLU/Dept. of Aquatic Sciences and AssessmentSammanfattning : 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). LÄS MER
3. An annual evaluation of CH4 oxidation in a freshwater lake
Kandidat-uppsats, Linköpings universitet/Tema MiljöförändringSammanfattning : 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. LÄS MER
4. Rhizosphere Priming and Methane Oxidation in Agricultural Soil - Effect of Land Use on Atmospheric Concentrations of CO2 and CH4 and Climate Change
Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildningSammanfattning : 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.

5. Modelling methane emissions from Arctic tundra wetlands : effects of fractional wetland maps
Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskapSammanfattning : 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. LÄS MER
