  1. 1. Exploring the effects of pressure on the magnetic properties of quasi-low dimensional quantum magnets via thermodynamic measurements

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

    Författare :Emelie Zhu; [2024]
    Nyckelord :Physics and Astronomy; Technology and Engineering;

    Sammanfattning : Four model solid state compounds were used to experimentally investigate the effects of pressure on the interactions in one- and two-dimensional Heisenberg magnetic models. BaCuSi2O6, BaCu2V2O8, SrCuO2 and CuGeO3 were successfully synthesized via solid-state reactions and characterized via x-ray diffraction. LÄS MER

  2. 2. The evolution of wetland restoration policy - A case study of Kristianstad Vattenrike

    Master-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Alexander Palmér; [2024]
    Nyckelord :Wetlands; Kristianstads Vattenrike; Collective action; Social norms; Policy attributes; Earth and Environmental Sciences; Social Sciences; Agriculture and Food Sciences;

    Sammanfattning : Wetlands are vital for biodiversity, socio-ecological systems, and carbon sequestration, but they present a complex challenge in crafting effective conservation policies. This study investigates a successful case of wetland conservation policy, focusing on the notable achievements of Kristianstad Vattenrike. LÄS MER

  3. 3. Structural analysis of HZO thin film and electrode using X-ray diffraction

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

    Författare :Elliot Winsnes; [2024]
    Nyckelord :HZO; hafnia; hafnium dioxide; zirconium dioxide; ferroelectricity; ferroelectric; synchrotron radiation; X-ray diffraction; Physics and Astronomy;

    Sammanfattning : Since its discovery in 2011, the ferroelectricity of thin films based on HfO2 has been studied intensively. In particular, thin films with a 1:1 ratio of HfO2 and ZrO2 (HZO) has been of great interest. The ferroelectricity arises from a non-centrosymmetric orthorhombic (o) phase of HZO whose prevalence is dependent on the processing conditions. LÄS MER

  4. 4. Vehicle dynamics modelling of electromagnetic suspensions for MAGLEV applications

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :Léa Chatelais; [2024]
    Nyckelord :MAGLEV; Dynamics; Requirements; Suspension; Vehicle modeling; MATLAB; MAGLEV; Dynamisk; Fordran; Upphängning; Fordon modell; MATLAB;

    Sammanfattning : MAGnetic LEVitation Guidance System (MAGLEV) technology was commercially introduced relatively recently in the guided transport field. It is based on removing the wheels and rails of classic railway systems and supporting and guiding the train with magnets and magnetic forces instead. LÄS MER

  5. 5. Konceptstudie kring snabb-fästen för skärutrustning till en motorsåg

    M1-uppsats, Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Författare :Emil Gustafsson; Marcus Wallén; [2023]
    Nyckelord :;

    Sammanfattning : This report describes a thesis project together with Husqvarna Group at the Advanced Development Handheld department. The aim of the project was to develop a prototype for a more efficient rapid bar exchange for one of Husqvarnas chainsaws. The reason for this is that the current design for changing the bar and chain is time consuming. LÄS MER
