  1. 16. Syntetiskt pärlemor : Producerat via in situ-kristallisation

    Master-uppsats,

    Författare :Pontus Blomberg; [2023]
    Nyckelord :Biomineralisation; Aragonite; Calcium; Carbonate; CaCO3; CNC;

    Sammanfattning : This thesis describes a sequence of experiments which have been performed with the intention to produce synthetic nacre. Synthetic nacre is a biomimetic material based on nacre, a material which can be found in mollusc shells. Nacre is a nanocomposite which has improved mechanical properties compared to the principal component aragonite (95% wt%). LÄS MER

  3. 17. The Adoption of New and Used Electric Vehicles : The difference in the impact of financial factors for new vs. used electric vehicles

    Magister-uppsats, Blekinge Tekniska Högskola/Institutionen för industriell ekonomi

    Författare :Pierre Johansson; China Venkatareddy Satti; [2023]
    Nyckelord :New Electric Vehicles; Used Electric Vehicles; Financial Factors;

    Sammanfattning : The growth of the market for electric vehicles (EVs) is increasing each year with record numbers of newly registered electric vehicles in 2022. Electric vehicles are considered the key component of a sustainable transportation sector. The knowledge of influential factors on purchase decisions for new EVs is high. LÄS MER

  4. 18. FTIR mätningar av absorptionsvätskor i Bioenergy Carbon Capture and Storage processer

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Isa Pettersson Haag; Emma Hedberg; Oliver Svahn; David Danielsen; [2023]
    Nyckelord :BECCS; FTIR; carbon dioxide; carbonate; bicarbonate; PCA;

    Sammanfattning : The effects of global warming are well understood. In order to combat this, society must move towards net zero emissions of green house gases, where carbon dioxide (CO2) plays a key role. In several IPCC climate scenarios that meet the Paris agreement, negative emission technologies that effectively remove CO2 from the atmosphere are included. LÄS MER

  5. 19. Environmental performance and sovereign bond yields: Evidence from emerging markets

    Magister-uppsats, Lunds universitet/Nationalekonomiska institutionen

    Författare :Kristin Unga; [2023]
    Nyckelord :sovereign yields; environmental performance; principal component analysis; Business and Economics;

    Sammanfattning : This thesis analyses if investors price a country’s environmental (E) performance into sovereign bond yields. The sample consists of 17 emerging countries from 2011 to 2020. LÄS MER

  7. 20. Identifying effects of adrenaline and dopamine binding on the beta2-adrenergic receptor structure and function using machine learning

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Joar Gunnarsson; Leon Bergner; [2023]
    Nyckelord :beta2-adrenergic receptor; GPCR; adrenaline; dopamine; Machine learning; Molecular dynamics simulation;

    Sammanfattning : The beta2-adrenergic receptor is a G-protein coupled receptor, involved in several physiological processes, which enables signaling through the cell membrane. To study the effect of dopamine and adrenaline binding on the receptor structure and function, we used machine learning methods applied to data from molecular dynamics simulations. LÄS MER
