  1. 1. PGE Geochemistry and Mineralogy of Dunite, Chromitite, and Laterite Samples from the Acoje Ophiolite Block, Philippines

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Michelle Dossey; [2023]
    Nyckelord :PGM; PGE; laterite; limonite; chromitite; dunite; platinum group minerals; platinum group elements; Acoje; Philippines;

    Sammanfattning : Ni-laterites have the potential to become unconventional ore deposits for platinum group elements (PGE). This study was conducted to determine enrichment trends of PGE as a result of the Ni-laterization process. LÄS MER

  3. 2. A theoretical framework for interpretation and prediction of magneto-optical measurements

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Viktor Frilén; [2023]
    Nyckelord :moke; tmoke; lmoke; pmoke; magneto-optical effects; layered media; dielectric function; maxwells equations; dielectric tensor; linear respons; magnetism; light induced transistions; DFT; SO;

    Sammanfattning : The interplay of experiments and theory is essential to deepen our understanding of magnetization dynamics. This thesis aims to serve as a bridge between these two aspects by establishing a mathematical framework that enables the computation of optical observable quantities based on theoretical models.

  4. 3. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Christopher Hallén; Marcus Johansson Storne; [2023]
    Nyckelord :;

    Sammanfattning : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. LÄS MER

  5. 4. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :William Gulding; [2023]
    Nyckelord :Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

    Sammanfattning : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. LÄS MER

  7. 5. Theoretical investigation of Co-dependence in magnetic high-entropy alloys

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Johan-Michael Kurak; [2023]
    Nyckelord :;

    Sammanfattning : High-entropy alloys (HEA) is a class of materials consisting of multiple principal elements that often crystallize in simple lattices such as body-centered cubic, face-centered cubic and hexagonal close-packed structures. Many HEAsexhibit exceptional mechanical properties, e.g. LÄS MER
