  1. 11. Evaluation of two-stage GAC filtration for PFAS reduction in drinking water

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Julia Söderberg; [2023]
    Nyckelord :Per- and polyfluoroalkyl substances PFAS ; Granular activated carbon GAC ; drinking water; removal efficiency; DWTP;

    Sammanfattning : PFAS, or per- and polyfluoroalkyl substances, are a group of chemicals found in a wide range of industrial and consumer products. Due to their persistent nature and widespread use, concerns have been raised about their impact on human health and the environment. LÄS MER

  3. 12. Simulating sustainable futures - Investigating the implications of CO2 emission caps on economic growth in the OECD

    Kandidat-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Anja Sophia Theopold; Ulrika Ericson; [2023]
    Nyckelord :Economic growth; Climate change; Absolute caps on emissions; Technological change; OECD; Business and Economics;

    Sammanfattning : The matters of economic growth and climate change are both widely subjected to discussions and policymakers are under immense pressure to make decisions that enhance economic growth and stop climate change. Policies that ensure economic growth have traditionally had a negative impact on climate change and vice versa. LÄS MER

  4. 13. The regional test of relationship between economic growth and CO2 emissions : --Evidence from Chinese provinces

    Kandidat-uppsats, Jönköping University/Internationella Handelshögskolan

    Författare :Thoth Mo; Weibin Wang; [2023]
    Nyckelord :EKC; high-income provinces; low-income provinces; Inverted U-shaped relationship; turning point;

    Sammanfattning : This thesis has investigated the validity of the Environmental Kuznets Curve in the provinces of China which assumes the increase in GDP per capita (income per capita) would generate the raise of CO2 emissions (pollution) until a turning point in which CO2 emissions start decreasing. The study includes 30 provinces over a period spanning from 2000 to 2019 by applying OLS and Fixed-effects regression model with panel data. LÄS MER

  5. 14. Biocatalysis in Pickering emulsions

    Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Författare :Christine Vera Isabel Schmidt; [2023]
    Nyckelord :Enzymes; Pickering emulsion; Amine Transaminases; Green Chemistry; Stereoselectivity; Biotechnology; Biology and Life Sciences;

    Sammanfattning : Employing enzymes as catalysts in the production of chiral amines that are both used as building blocks and active pharmaceutical ingredients might be promising due to milder reaction conditions compared to non-biological catalysts, exclusion of heavy metals, high selectivity towards substrates and precision in chirality of the products. Transaminases are attractive for the use in this process. LÄS MER

  7. 15. Model Predictive Urea Dosing Control Strategy for Heavy-Duty Diesel Vehicles

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Mathias Schmekel; [2023]
    Nyckelord :Model predictive control; Selective catalytic reduction; Nitrogen oxides; Modell-prediktiv reglering; Selektiv katalytisk reduktion; Kväveoxider;

    Sammanfattning : Stricter requirements on the reduction of Nitrogen Oxides (NOx) in the emissions of heavy-duty diesel vehicles drives development for more efficient aftertreatment systems. An ammonia covered catalyst is one of the most successful technologies in reducing NOx by converting it into the harmless byproducts water and nitrogen. LÄS MER
