    Sammanfattning : The combustion of fossil fuels has for a long time been a problem from an environmental and sustainability point of view, especially when it comes to the emissions of atmospheric carbon dioxide. The environmental concern has for instance shifted the attention towards finding new sustainable alternatives for producing chemicals and fuels, as a substitute to today’s dependence on fossil based crude oil.

  4. 23. Towards the use of Alcohol dehydrogenases as biocatalysts for stereoselective isotope labeling of aromatic alcohols.

    Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - BMC

    Författare :Irena Serveta; [2018]
    Nyckelord :;

    Sammanfattning : The enzyme ADH-A and one of its mutants ADH-A C1B1 from ​ Rhodococcus ruber,​ have in previous studies been proved to act as proper biocatalysts, fully capable of performing redox reactions. Two redox reactions were studied during this project, were those enzymes act as catalysts. LÄS MER

  5. 24. Perfluoroalkyl substances (PFASs), flame retardants and cyclic volatile methylsiloxanes in indoor air in Uppsala, Sweden : occurrence and human exposure assessment

    Master-uppsats, SLU/Dept. of Aquatic Sciences and Assessment

    Författare :Bo Sha; [2017]
    Nyckelord :passive air sampling; SIPs; indoor air; PFAS; flame retardants; siloxanes; human exposure;

    Sammanfattning : Indoor air samples were collected from three buildings located at the Swedish University of Agricultural Science (SLU) campus in Ultuna, Uppsala, Sweden and from residences of nine volunteers working in the three buildings. Sorbent-impregnated polyurethane foam (SIP) disk passive air samplers were deployed in different types of rooms in the three buildings including computer room (n = 1), labs (n = 3), lecture rooms (n = 3), offices (n = 8) and dining areas (n = 3) and homes (n = 9) of the volunteers between September and November in 2016.

  7. 25. Preparation, characterization and testing of model catalysts for CO oxidation and CO2 hydrogenation

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Stefano Albertin; [2017]
    Nyckelord :Surface science; Rhodium; Nanoparticles; Catalysis; CO2; Physics and Astronomy;

    Sammanfattning : A joint research between Lund University and Chalmers Competence Centre for Catalysis have shown promising results for a Rh-based catalyst for CO2 hydrogenation catalytic applications. The original catalyst consisted of a dispersion of nanoparticles onto a porous 3D oxide network. LÄS MER
