  1. 1. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

    Master-uppsats, Lunds universitet/Materialteknik

    Författare :Johan Ranstad; [2023]
    Nyckelord :Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

    Sammanfattning : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. LÄS MER

  3. 2. Laminated HZO on InAs: A study of as-deposited ferroelectricity

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :André Andersen; [2022]
    Nyckelord :Ferroelectricity; HZO; InAs; III V; As-deposited ferroelectricity; BEOL; Nanoelectronics; Nanoprocessing; Nanotechnology; ALD; MOSCAP; Memory Technology; Technology and Engineering;

    Sammanfattning : As the limits of transistor feature size scaling is reaching its saturation, new innovations are needed to prevent performance loss. High performance transistors on the III/V semiconductor platform implemented with ferroelectric oxides might in the future satisfy this demand. LÄS MER

  4. 3. Circularity of aluminium: Mapping difficulties in scrap circulation : A literature study and interviews with actors with focus on aluminium circulation in Sweden

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Felix Fernström; Erik Karpe; Paul Thellenberg; [2022]
    Nyckelord :Aluminium; Aluminium alloys; contaminants; impurities; scrap; tramp elements; Aluminium; aluminiumlegeringar; föroreningar; orenheter; skrot; spårämnen;

    Sammanfattning : Aluminium has great properties that are utilised the world over, but the production of primary aluminium is very energy intensive. In order to reduce the energy-cost, the aluminium can be recycled by re-melting aluminium scrap. LÄS MER

  5. 4. Evaluation of Peridynamics and Its Application in Harmonic-Structured Material Simulations

    Master-uppsats, Lunds universitet/Mekanik

    Författare :Theodor de Sousa; [2020]
    Nyckelord :peridynamics; peridigm; harmonic-structured materials; computational mechanics; fracture modelling; Technology and Engineering;

    Sammanfattning : Materials are constantly sought to be improved in different manners. Two of the most common characteristics to improve are strength, and ductility. Historically, materials are modified homogeneously to achieve improvement, while the past century has also seen composite materials becoming standard-issue within various industries. LÄS MER

  7. 5. Synthesis and Characterization of some Photo-CORM and Photosensitizers

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Joachim Björklund; [2019]
    Nyckelord :Inorganic Chemistry; Bioinorganic Chemistry; CORM; Photo-CORM; Photosensitizers; Synthesis; Characterization; Oorganisk kemi; Chemistry;

    Sammanfattning : It is well known that Carbon monoxide is a toxic and hazardous gas, but during recent years it has been proven that using a controlled concentration, carbon monoxide can in fact be used as a therapeutic agent, and can contribute to decrease malaria, treat cardiovascular and lung diseases and potentially even treat cancer, among other things. The main problem in using carbon monoxide directly is the fact that it is not trivial to control the volume of gas inhaled, compromising its use as a therapeutic agent. LÄS MER
