  1. 1. Towards an understanding of the Retraction of TYPE IV PILI as a Mechanoresponse upon surface contact in Pseudomonas Aeruginosa

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Antoine Loussouarn; [2022]
    Nyckelord :Mechanosensing; Microscopy; Bacteria; Microfabrication; Genetics; Molecular Biology; Biophysics;

    Sammanfattning : Pseudomonas Aeruginosa is an opportunistic bacterium which is involved in nosocomial infections and which causes increasing concern in healthcare due to its high antibiotic resistance. During an infection by P.aeruginosa, the bacteria proliferate in the host’s organism by leveraging motility abilities. LÄS MER

    Kandidat-uppsats,

    Författare :Evelina Roxner; Ronja Olsmats Baumeister; [2019]
    Nyckelord :nanofabrication; optical lithography; photo lithography; line contacts; microfabrication; rear contact passivation; passivation layer; sub-micrometer features; thin film; ultra-thin film; solar cells; CIGS; aluminiumoxide;

    Sammanfattning : Thin film copper, indium, gallium, selenide (CIGS) solar cells are promising in the field of photovoltaic technology. To reduce material and fabrication cost, as well as increasing electrical properties of the cell, research is ongoing towards ultra-thin film solar cells (absorption layer thickness less than 500 nm).

  5. 4. Investigation of the heat transfer of enhanced additively manufactured minichannel heat exchangers

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Hamidreza Rastan; [2019]
    Nyckelord :Minichannel; Microchannel; Heat exchanger; Additive manufacturing; 3D printing; Numerical simulation; CFD; Comsol;

    Sammanfattning : Mini-/microchannel components have received attention over the past few decades owing to their compactness and superior thermal performance. Microchannel heat sinks are typically manufactured through traditional manufacturing practices (milling and sawing, electrodischarge machining, and water jet cutting) by changing their components to work in microscale environments or microfabrication techniques (etching and lost wax molding), which have emerged from the semiconductor industry.

  7. 5. Offline study of next generation EUV pellicle materials and performances : From experimental design to material characterization

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Susanna Licheri; [2019]
    Nyckelord :Semiconductors; Nanotechnology; EUV Lithography; EUV Pellicle; Qualification study; Halvledare; nanoteknik; EUV litografi; EUV Pellicle; kvalificerings studie;

    Sammanfattning : Lithography is the most crucial step in the semiconductor microfabrication workflow. Continuous features size shrinking co-occurs with the reduction of the exposure wavelength: a move from 193 nm light to extreme ultra-violet (EUV) at 13.5 nm is performed. The change poses a vast number of challenges that have been overcome in the past years. LÄS MER
