  1. 1. Polarisation-resolved super-resolution microscopy

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Wouter Duverger; [2021]
    Nyckelord :biophysics; microscopy; super-resolution microscopy; polarisation microscopy; STED; Physics and Astronomy;

    Sammanfattning : This project aims to implement polarisation microscopy on the Tegenfeldt STED (stimulated emission depletion) microscope. STED microscopy is a targeted optical super-resolution method that can attain sub-diffraction resolution using visible light. LÄS MER

  3. 2. Energy Efficient Composites for Automotive Industry.

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

    Författare :Mariana Rojas; [2021]
    Nyckelord :Hybrid composites; Short fibres; Carbon fibres; Flax fibres; Manufacturing; Resin Transfer Moulding RTM ; Vacuum infusion; Tensile tests; Flexural tests;

    Sammanfattning : Hybrid composites play a key role in sustainable development. For many years, carbon fibres in an epoxy matrix have been an attractive option for many structural applications because of their higher specific mechanical properties mostly. LÄS MER

  4. 3. Live 3D imaging quantum LiDAR

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Theodor Staffas; [2021]
    Nyckelord :lidar; otdr; snspd; lidar; otdr; snspd;

    Sammanfattning : In this thesis, I demonstrate a single­photon Light Detection And Ranging, (LiDAR)system operating at 1550 nm capable of reconstructing 3D environments live withmm resolution at a rate of 400 points per second using eye­safe laser pulses. Thesystem was built using off­-the-­shelf optical components and analysis was performedusing open-­source software. LÄS MER

  5. 4. Transparent paper: Evaluation of chemical modification routes to achieve self-fibrillating fibres

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

    Författare :Paulina Sandberg Birgersson; [2020]
    Nyckelord :Transparent paper; nanopaper; nanocellulose; chemical modification of cellulose; cellulose nanofibrils CNF ; Transparent papper; nanopaper; nanocellulosa; kemisk modifiering av cellulosa; cellulosa nanofibriller CNF ; nanopapper;

    Sammanfattning : Transparenta papper tillverkade av cellulosa nanofibriller (CNF), visar stor potential att kunna ersätta petroleumbaserade plaster inom många användningsområden, till exempel för mat- och varuförpackningar. CNF, även känt som nanocellulosa, kombinerar viktiga cellulosaegenskaper, med unika egenskaper hos nanomaterial. LÄS MER

  7. 5. Use of Diffuser Fibres in the Treatment of Prostate Cancer by Interstitial Photodynamic Therapy

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Shaineze Afir; [2018]
    Nyckelord :photodynamic therapy; cancer treatment; matlab; diffuser fibres; biomedical; Mathematics and Statistics;

    Sammanfattning : SpectraCure AB is a start-up company aiming at treating internal solid tumours such as prostate tumours with an innovative technology called ‘Interstitial Photodynamic Therapy’. This treatment requires the use of fibres to deliver the amount of light required to activate a drug injected to the patient which leads to the destruction of the tumours. LÄS MER
