  1. 6. In situ X-ray diffraction studies of vertically aligned CsPbBr3 nanowire arrays

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

    Författare :Jesper Larsson; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The past decade has seen a great interest in the development of metal halide perovskite materials for use in photo-optical devices, due to the excellent photo-optical properties of these materials. The primary limitation to industrial adoption, and the subject of much research, is the susceptibility of these materials to degradation from exposure to various factors such as air, heat and moisture.

  3. 7. Application of ERT for Quality Assurance in Jet Grouting Columns; A development of an alternative quality control

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Edvin Nilsagård; Rebecka Knutsson; [2022]
    Nyckelord :ert; jet grouting; quality control; pygimli; res2dinv; resistivity; Technology and Engineering;

    Sammanfattning : With the increased urbanization major cities are facing, expansion of larger facilities and households are inevitable. Expansion means larger areas of the surface needs to be used where the risk of varying subsurface soil properties increases with larger surface areas. LÄS MER

  4. 8. Feasibility Study of Resistivity Measurement of Metal Surfaces to Address Potential Dislocations Caused by Surface Conditioning

    Master-uppsats, Uppsala universitet/FREIA

    Författare :Mircea-George Coman; [2022]
    Nyckelord :;

    Sammanfattning : High electrical fields are needed inside the accelerating cavities of particle accelerators in order to accelerate the particles to higher energies in shorter distances. But high electrical fields will lead to electrical breakdowns. LÄS MER

  5. 9. Investigation of the Magnetic- and Electron Transport Properties of Fe/MgO Superlattices

    Kandidat-uppsats, Uppsala universitet/Materialfysik

    Författare :Ali Rostom; David Holmgren; [2022]
    Nyckelord :Fe MgO superlatice; interlayer exchange coupling; Van der Pauw; electronic transport; magnetic field; resistive properties; 3D memory storage;

    Sammanfattning : Anti-ferromagnetic interlayer exchange coupling between iron layers in Fe/MgO superlatices have recently been of interest among researchers for its potential application in 3D memory storage in computers (hard drives) and in the research field of spintronics. Thinfilms and bi-layers between the 10-100 ångström range in thicknesses were analyzed for its resistive properties during different conditions. LÄS MER

  7. 10. Spårning av vägsalt och vattenlösliga  föroreningar med CVES och EM  prospektering

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

    Författare :Alicia Holmberg; Tania Bethoon; [2022]
    Nyckelord :CVES; EM; road salt; water soluble pollutants; geophysical measurement method; ABEM Terrameter LS; Slingram; CVES; EM; vägsalt; vattenlösliga föroreningar; geofysiska mätmetoder; ABEM Terrameter LS; Slingram;

    Sammanfattning : Vid utformning av väginfrastruktur borde trafikrelaterade utsläpp med ursprung från väg- och däckslitage samt halkbekämpning tas hänsyn till för att nå en verklig hållbar utveckling. Exempel på vägrelaterade utsläpp är aluminium, bly, koppar, kadmium, krom och zink. LÄS MER
