  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. The Perception of Corruption in correlation to Homicides : A time-series cross-sectional empirical global study, with specific focus on the Latin American region

    University essay from Uppsala universitet/Institutionen för freds- och konfliktforskning

    Author : Lotta Ericsson; [2024]
    Keywords : Homicides; Perception of Corruption; Latin America; Grievance motivated violence; Corruption;

    Abstract : Most research that has examined the variation in homicide levels has examined their correlation with socioeconomic structural variables. In Latin America however, economic and social development has occurred, but high homicide levels remain, suggesting the involvement of other influencing factors. READ MORE

  4. 3. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Nicolai Laufer; [2023-06-21]
    Keywords : ;

    Abstract : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. READ MORE

  5. 4. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Anna Wagne; [2023]
    Keywords : Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

    Abstract : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. READ MORE

  6. 5. Influence of structural complexity of the Rumperöd forest on evapotranspiration

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Madeleine Durdek; [2023]
    Keywords : Forest structural complexity; evapotranspiration; vapour pressure deficit; eddy covariance; Earth and Environmental Sciences;

    Abstract : The influence of Forest Structural Complexity (FSC) on evapotranspiration (ET) was investigated in a mixed forest of Southern Sweden where micrometeorological Eddy Covariance (EC) measurements were conducted for the years 2015 to 2022. For each year, the top 25% of Vapour Pressure Deficit (VPD) were selected to emphasize the response of ET to the driest atmospheric conditions. READ MORE
