  1. 1. High-Temperature Thermal Energy Storage for Innovative Hybrid CSP/PV Plants : A Comprehensive Design Optimization

    University essay from KTH/Energiteknik

    Author : Lorenzo Centonze; [2023]
    Keywords : ;

    Abstract : By means of a literature review, critical parameters in the context of thermal energy storage systems, particularly packed bed thermal energy storage systems are identified. The goals of this thesis project are to come up with an optimized design for a PBSTES and to evaluate the thermal performance of alternative storage materials derived from byproducts of industrial processes and natural rocks in order to reduce the environmental impact of the designed system.

  3. 2. Syn-Magmatic Deformation Structures in the Slaufrudalur Pluton, East Iceland

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Chun Hei Ho; [2023]
    Keywords : Granite; Iceland; magma chamber; magmatic microstructure; melt fraction; mush; pluton; rheology; strain; syn-magmatic deformation;

    Abstract : Structures and deformation mechanisms of magmatic rocks are controlled by rheology. An increase in melt fraction can weaken a rock body and localises significant amount of strain. This interplay between rheology, melting and deformation in a magma reservoir, however, is not always clearly documented in literature. READ MORE

  4. 3. Assessing the controls of the fluoride concentrations in the groundwater of Gothenburg area

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Crayton Enga Bessong; [2022-11-04]
    Keywords : Fluoride; Groundwater; Fluorite; Solubility; Fluorosis; Idefjorden Terrane;

    Abstract : The human uptake of fluoride can promote healthy teeth in low concentration (1.5 mg/l). Drinking water is a major route to which we humans are expose to fluoride intake. READ MORE

  5. 4. Redesign of a tribological pin-on-disc machine

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Michal Szumin; [2022]
    Keywords : tribometer; particulate matter; studded tyres; tyre-road contact; tribometer; partiklar; dubbdäck; kontakt mellan däck och väg;

    Abstract : In contradistinction with road transport exhaust particulate matter (PM) emission, non-exhaust PM emission has not decreased substantially in recent years. One source of non-exhaust PM emission is studded tyre-pavement contact. READ MORE

  6. 5. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Nsioh Elvis Nkioh; [2022]
    Keywords : geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

    Abstract : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. READ MORE
