1. 1. APPLICATION OF IN SITU Rb-Sr DATING AND GEOCHEMICAL INVESTIGATIONS ON A NEW, 1.52-1.56 GA. OLD PEGMATITE FIELD IN THE ARCHIPELAGO OFF GOTHENBURG, IDEFJORDEN TERRANE, WESTERN SWEDEN

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Laszlo Zorc; [2023-08-18]
   Nyckelord :;

   Sammanfattning : In this study, Rb-Sr geochronology was used to determine the crystallization/cooling ages of muscovites and biotites from mapped primitive barren and rare element pegmatites in the Stora-Le-Marstrand Formation in the southwestern archipelago of Gothenburg. The results indicate that primitive barrens can be linked to the DG2 deformation event that occurred 1. LÄS MER

3. 2. Managing a diversified business model portfolio : A digital platform company perspective

   Master-uppsats, Uppsala universitet/Företagsekonomiska institutionen

   Författare :Viktor Andersson; Filip Möcander; [2022]
   Nyckelord :Business models; Business Model Diversification; Business Model Innovation; Business Model Integration; Cannibalization; Synergy;

   Sammanfattning : In parallel with the popularization and widespread diffusion of the internet, interest in the concept of different business models (BM) has increased dramatically, attracting the attention of both scholars and managers alike (Dodgson, Gann and Phillips, 2013). As a result, an increasing number of businesses decide to establish themselves and compete in the digital arena (Lee, 2001); many of which are employing what is called a platform model capitalizing on the ability to operate with several BMs simultaneously (Gu, Kannan and Ma, 2018; Aversa, Haefliger, Hueller and Reza, 2021).

4. 3. Electrochemical Behavior of the High Entropy Oxide (Mg,Co,Ni,Zn)1-xLixO (x=0,35)

   Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Rasmus Sandström Kinnane; [2022]
   Nyckelord :high entropy oxides; lithium-ion battery; x-ray diffraction; scanning electron microscopy; cyclic voltammetry;

   Sammanfattning : Today's society is currently developing lithium-ion batteries to eventually replace the use of fossil fuels. High entropy oxides is a new type of material to use as an anode in the lithium-ion battery. These high entropy oxides may consist of a few different transition metals including lithium and oxygen.

5. 4. Investigations of Large Size Non-Metallic Inclusions in the Nickel-based alloy Inconel 718

   Kandidat-uppsats, KTH/Materialvetenskap

   Författare :Yuehui Ma; Wardah Saleem; [2022]
   Nyckelord :;

   Sammanfattning : Inclusions of different types are present in all steels. How dangerous these are for the properties of the material depends on their chemical composition and the manufacturing process. LÄS MER

7. 5. Modelling the global water cycle – the effect of Mg-sursassite on the amount of globally subducted water

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Författare :Nils Benjamin Gies; [2021-07-05]
   Nyckelord :;

   Sammanfattning : Subduction of hydrated lithospheric mantle is the most important process regarding the transfer of significant amounts of water to depths exceeding 350 km. Hence, the interplay of the thermal structure within the subducted slab together with the PT-stability fields of hydrous ultra-high pressure phases control the dehydration of the slab and the amount of water transported into the deeper mantle.
