  1. 1. Fossilfri plast i Sverige

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Miljö- och energisystem

    Författare :Viktor Wahldén; [2024]
    Nyckelord :Plast; plastanvändning; kol; grönt kol; fossilfri; cirkularitet; kolkällor; avfallsektorn; skogsindustrin; energi; Technology and Engineering;

    Sammanfattning : Med bakgrund i den fossilfria omställningen var målet med detta arbete att undersöka hur stort behovet av kol till svensk plastanvändning 2050 är samt att jämföra kolbehovet med mängden tillgängligt fossilfritt kol. För att svara på detta utformades tre scenarier på plastanvändningen. LÄS MER

  3. 2. The Pseudo-Unitary Group U(p,q) in Quantum Magnonics

    L3-uppsats, Uppsala universitet/Materialteori

    Nyckelord :quantum magnonics; materials theory; pseudo-unitary; quantum mechanics; magnons; antiferromagnets;

    Sammanfattning : The study of magnons is an essential part of combining quantum information science and spintronics, allowing for the investigation of quantum properties such as entanglement in solid-state devices. Magnons are commonly described using the theory of T. Holstein and H. LÄS MER

  4. 3. Effects of natural aging and low strain-rate on mechanical properties of aluminium alloy sheets used in automotive industry

    Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Amirhossein Gholami; Ali Abedisamarin; [2024]
    Nyckelord :Ageing. AA6014. AA6016;

    Sammanfattning : These days, lightweight materials such as aluminum alloy sheets, especiallythose in the AA6xxx series, are in high demand for use inthe automotive industry. During natural aging, the properties of aluminummay undergo significant changes due to the diffusion of atomswithin the crystal structure, impacting the strength and formabilityof aluminum sheets.
