  1. 1. Use of Pulse Thermography for Characterization of Defects in Polymer Composites

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Kim Klöckner; [2023]
    Nyckelord :NDT; Pulse Thermography; polymer composites; boats manufacturing; end-of-life structures; defect characterization;

    Sammanfattning : In this project, the possibility of using thermography as a non-destructive testing tool in the manufacturing process of boats and to assess the quality of end-of-life composite structures has been explored. To do so, a literature surview regarding the current applications of thermography and the techniques currently used for quality control in the boats industry has been conducted. LÄS MER

  3. 2. Flashlamp Annealing for Improved Ferroelectric Junctions

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

    Författare :Theodor Blom; [2023]
    Nyckelord :Flashlamp annealing; ferroelectricity; hafnia oxide; III-V semiconductor; thermal annealing; device performance; Technology and Engineering;

    Sammanfattning : The effects of flashlamp annealing (FLA) on the quality of ferroelectric HfxZr1–xO2 (HZO) interfaces, integrated on InAs substrates, are evaluated. For the integration of ferroelectric HZO on III-V semiconductors the crystallization via rapid thermal processing (RTP) can severely degrade the HZO/III-V interface. LÄS MER

  4. 3. Fabrication and Characterization of Quantum-well Field Effect Transistor

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

    Författare :Yang Fu; [2022]
    Nyckelord :quantum-well field-effect transistor; InGaAs; subthreshold swing; sheet resistance; contact resistance; electron mobility; Post Metallization Annealing; electrostatic control; Physics and Astronomy;

    Sammanfattning : The project aims to optimize the design and fabrication of InGaAs quantum-well field-effect transistor (QW-FET) by investigating transfer and output characteristics of the QW-FET. This work found a lower source/drain contact resistance solution starting with fabricating micrometer-level gate length transistors. LÄS MER

  5. 4. Characterization of the role of RbfA and KsgA in ribosome function

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Carina Kvernes Macpherson; [2022]
    Nyckelord :;

    Sammanfattning : Ribosome biogenesis is the maturation and accurate assembly of ribosomal RNA and proteins to form functional ribosomes competent to enter the translation cycle, facilitated by the action of ribosome biogenesis factors. RbfA and KsgA are two factors involved in late stages of the 30S subunit biogenesis, yet before translation initiation. LÄS MER

  7. 5. Fatigue properties of Laser Powder Bed Fusion (LPBF) built 21-6-9 stainless stee

    Master-uppsats, Högskolan Väst/Avdelningen för avverkande och additativa tillverkningsprocesser (AAT)

    Författare :Jayanth Krishna; [2021]
    Nyckelord :stainless steels; LPBF; Fatigue; 21-6-9;

    Sammanfattning : Fatigue performance is one of the important mechanical properties which is hindering some of the additive manufacturing build structures. The main objective of this study is to investigate the fatigue life dependence of the 21-6-9 austenitic stainless-steel build using the laser powder bed fusion (LPBF) technique. LÄS MER
