  1. 11. Petrological, geochemical and structural evidence of fluid-rock interaction in the Siljan Ring

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : William Crang; [2024]
    Keywords : methane; hydrothermal fluids; fluid-rock interaction; impact craters; reduction haloes; pyrite preservation; Siljan Ring;

    Abstract : The Siljan Ring in Dalarna, Sweden is the site of the largest meteor impact crater in Europe and has long been a topic of discussion regarding methane production. However, the source of this methane and the timing of production in relation to the impact remain unclear. READ MORE

  3. 12. Measuring copper abundances in the Galactic Bulge

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

    Author : Nikolei Höglinger; [2024]
    Keywords : Copper; Galaxy: abundances; Galaxy: bulge; Chemical Evolution; Physics and Astronomy;

    Abstract : Context: The chemical evolution of Cu in the Galactic bulge have been studied in a few studies using red giant branch stars, but the ages of individual red giant stars are difficult to determine. In addition, the bulge has been a challenging region of the Milky Way galaxy to obtain high-resolution spectra of stars, except when observing through certain few small fields into the bulge that are known to have low extinction.

  4. 13. Synthesis of aromatic thiol ligands for the formation of thermoelectric materials

    University essay from KTH/Kemi

    Author : Clément Bouchut; [2024]
    Keywords : ligand; organic chemistry; organic synthesis; thermoelectric materials; thiol; ligand; organisk kemi; organisk syntes; termoelektriska material; tiol;

    Abstract : I detta arbete så har en uppsättning aromatiska ditiol-ligander framställts (3,5-dimerkaptobensoesyra I, methyl-3,5-dimerkaptobensoat II, 3,5-dimerkaptotoluen III, 4,6-dimerkaptoisoftalaldehyde IV). En trestegssyntes innehållande Newman-Kwart omlagring som nyckelsteg användes för framställning av föreningarna I-III medan förening IV togs fram via en annan syntesväg. READ MORE

  5. 14. Influential Factors and Key Actors Shaping Sustainability Assurance Opinions: A Case Study of a Big-4 Firm

    University essay from Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Author : John Gerendas; Axel Tottie-Håkansson; [2024]
    Keywords : Sustainability assurance; CSRD; Comfort; Task-oriented language; Materiality construction;

    Abstract : The rise in sustainability reporting has increased the demand for sustainability assurance, especially in the light of new legislation, requiring more companies to undergo third-party assurance. This thesis provides insights into the practical work of a sustainability assuror in the sustainability assurance process and how sustainability assurance opinions are formed as well as how materiality is constructed.

  6. 15. Flow of charged particles in Pb-Pb and pp collisions at the LHC

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

    Author : Mohamed Berkat; [2024]
    Keywords : Quark Gluon Plasma; QGP; Quantum Chromodynamic; QCD; flow coefficients; Event Plane; Cumulants; ALICE; Physics and Astronomy;

    Abstract : This thesis investigates the transition of Quantum Chromodynamic (QCD) matter to a strongly interacting Quark Gluon Plasma (QGP), where quarks and gluons become deconfined. The expansion of this plasma exhibits characteristics of an ideal relativistic hydrodynamics system, suggesting a behavior similar to that of a perfect fluid. READ MORE
