  1. 31. Study of Reverse Water Gas Shift reaction using bimetallic catalysts on active supports : The case of unpromoted and K-promoted FeCu/CeO2

    Master-uppsats, KTH/Kemiteknik

    Författare :Carlo Sala; [2022]
    Nyckelord :CO2 utilization; RWGS; catalyst; active catalytic support; characterization; CO2 användning; RWGS; katalysator; aktiva katalysatorbärare; karakterisering;

    Sammanfattning : Reverse Water Gas Shift Reaction (RWGS) är en attraktiv lösning för CO2-använding och minskning av utsläppen i atmosfären. Denna reaktion begränsas av termodynamiken och det finns problem med storskalig tillämpning. För att förbättra genomförandet av processen krävs utveckling av en effektiv katalysator. LÄS MER

  3. 32. 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.

  4. 33. EBSD Investigation of High-Temperature Magnetite from Apatite-Iron-Oxide Deposits: Implications for the Formation of Giant Kiruna-Type Deposits

    Master-uppsats, Uppsala universitet/Mineralogi, petrologi och tektonik

    Författare :Jens Henriksson; [2022]
    Nyckelord :Kiruna-type deposit; electron backscattered diffraction; crystal settling; Fe-O systematics; crystal alignment;

    Sammanfattning : European iron production is to a large extent dependant on massive Kiruna type apatite-iron ore deposits. In this contribution, high-temperature magnetite samples from apatite-iron-oxide deposits are investigated by means of Electron Backscattered Diffraction. However, the origin of Kiruna-type deposits is still unresolved. LÄS MER

  5. 34. Non-perturbative models of diffractive hadronic collisions

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Edgars Karnickis; [2022]
    Nyckelord :diffractive process; proton-proton collision; elastic; parton; PDF; saturation; Physics and Astronomy;

    Sammanfattning : In this thesis, a new model for diffractive proton-proton collisions is presented. Interpreting protons as systems of many partons, we treat diffraction in terms of elastic interactions between the partons of the colliding protons. LÄS MER

  7. 35. Development of alkaline earth metal-based, metal-organic frameworks for greenhouse gas sorption

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Ali Maghsoodpoor; [2022]
    Nyckelord :Metal-organic Framework; gas sorption;

    Sammanfattning : Metal-organic frameworks (MOFs) constructed from metal atoms connected by organic linkers have received extensive attention for greenhouse gas separation in the past decades. Moreover, their large surface area makes them a promising candidate as adsorbents for gas sorption. LÄS MER
