  1. 1. 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

  3. 2. Microfluidic sorting of sperm for assisted reproduction - An evaluation of ZyMōt multi sperm separation device

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Emma Olofsson; [2023-06-22]
    Nyckelord :Assisted reproduction technologies Spermatozoa DNA fragmentation Density-gra- dient centrifugation Microfluidics ZyMōt Multi;

    Sammanfattning : Infertility is a worldwide problem and the main reason for the use of assisted reproductive technol- ogy (ART). In-vitro fertilization (IVF) is one ART treatment normally used, where the fertilization of oocytes occurs in vitro. LÄS MER

  4. 3. Utvärdering av nötningsmekanismer för verktyg till jordbearbetning : För ett hållbart jordbruk i framtiden

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Martin Hallhagen; [2023]
    Nyckelord :jordbruk; tribologi; metodutveckling; nötning;

    Sammanfattning : In the agricultural industry, cultivator tines are used for stubble cultivation and seedbed preparation. They are exposed to rapidly developing abrasive wear, which becomes a major economic problem. The occurring wear in the tines is heavily dependent on the characteristics of the soil which it passes through. LÄS MER

  5. 4. Characterization of Mitilysin Pores by Cryo-electron Microscopy

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Vladimir Novakovic; [2023]
    Nyckelord :Mitilysin; Mly; Structural Biology; Cryo-EM; pore; toxin; pore forming proteins; pore forming toxins; PFP; PFT;

    Sammanfattning : Pore forming toxins (PFTs) are a large group of proteins found mainly in bacteria with some exceptions found in animals. They bind and form pores in their target membranes and form pores, which leads to cell death. Among these are cholesterol-dependent cytolysins (CDC), which require the presence of cholesterol to bind target membranes. LÄS MER

  7. 5. Biopolymers processed and used as enzyme carriers

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Dániel Mészáros; [2023]
    Nyckelord :Biobased materials; plasticized sodium alginate; water stability; extraction kinetics; enzyme carrier; Biobaserade material; Mjukgjort natriumalginat; Vattenstabilitet; extraktionskinetik; Enzymbärare;

    Sammanfattning : Syftet med detta masterprojekt var att undersöka möjligheten att använda biobaserat, mjukgjort natriumalginat (NaAlg) som enzymbärare. Alginaterna görs traditionellt bearbetbara genom att tillsätta olika mjukgörare, såsom polyoler (glycerol, sorbitol, etc.), i detta arbete användes glycerol. LÄS MER
