  1. 1. Driven by Zero Emissions or Paramount Prestige? - Investigating the Coexistence of Environmental Concern and Materialism in Predicting Purchase Intentions of Premium Electric Cars

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Gustav Olofsson; Pontus Winblad; [2023-07-03]
    Nyckelord :Premium Electric Cars; Consumer Intentions; Theory of Planned Behavior; Environmental concern; Materialism; Sustainability Luxury Paradox; SEM Analysis;

    Sammanfattning : As the world embraces sustainability, markets align with the shift and undergo transformations. One of which is the luxury segment, from which the integration of sustainability challenges the theorized paradoxical relationship of the two concepts. LÄS MER

  3. 2. In-Situ Investigation of Particle Assisted GaSb Nucleation Using Environmental TEM

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Aidas Urbonavicius; [2023]
    Nyckelord :ETEM; Nucleation; GaSb; Nanowires; Materials chemistry; Technology and Engineering; Chemistry;

    Sammanfattning : III-V semiconductor material based nanowires have been extensively studied and shown to be a very exciting building block for future electronics. Material systems such as GaSb show a lot of promise in optoelectric and thermoelectric generation applications because of its high electron mobility and small bandgap. LÄS MER

  4. 3. Analys av platinaytor och platinatennytor under katalytisk etanoloxidation med röntgenfotoelektronspectroskopi

    Magister-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Författare :Mats Viktor Löfstrand; [2023]
    Nyckelord :Pt3Sn; APXPS; Ethanol oxidation; Pt 111 ; Pt 223 ;

    Sammanfattning : Fuel cells are more efficient and cleaner than combustion engines. Ethanol as a fuel has a high energy density and is safer and easier to handle than hydrogen which is normally used in fuel cells. If efficient fuel cells on alcohol were available, they could be used for engines and power sources for electronics. LÄS MER

  5. 4. Thermodynamic modelling of the copper-zinc-tin ternary system : A study towards lead-free brass

    Master-uppsats, KTH/Materialvetenskap

    Författare :Caterina Radogna; [2023]
    Nyckelord :Brass-based alloys; Lead-free brass; Calphad; Thermo-Calc; Thermodynamic description; Mässingsbaserade legeringar; Blyfri mässing; Calphad; Thermo-Calc; Termodynamisk beskrivning;

    Sammanfattning : Lead (Pb) is frequently used as an alloying element in brass to enhance machinability and castability. However, this element poses a significant risk to human health and the environment. The 2021 revision of the Drinking Water Directive imposed stricter limits on Pb content in brass, encouraging the development of lead-free brass. LÄS MER

  7. 5. Distance Consistent Labellings and the Local List Number

    Kandidat-uppsats, Linköpings universitet/Algebra, geometri och diskret matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Anders Henricsson; [2023]
    Nyckelord :distance-consistence; graph labelling; graph distance; avstånds-konsistens; grafmärkning; grafavstånd;

    Sammanfattning : We study the local list number of graphs introduced by Lennerstad and Eriksson. A labelling of a graph on n vertices is a bijection from vertex set to the set {1,…, n}. Given such a labelling c a vertex u is distance consistent if for all vertices v and w |c(u)-c(v)|=|c(u)-c(w)|+1 implies d(u,w)≤ d(u,v). LÄS MER
