  1. 1. Birefringence: Effects and Implications on In-Ice Radio Detection of High-Energy Neutrinos

    Master-uppsats, Uppsala universitet/Högenergifysik

    Författare :Nils Heyer; [2022]
    Nyckelord :Birefringence; Cosmic Neutrinos; In-ice radio propagation;

    Sammanfattning : The detection of high-energy neutrinos in the EeV range requires new detection techniques to cope with the small expected flux. The radio detection method, utilizing Askaryan emission, can be used to detect these neutrinos in polar ice. LÄS MER

  3. 2. Simulation of birefringence effects for high-energy neutrino detectors

    L3-uppsats, Uppsala universitet/Högenergifysik

    Författare :Nils Heyer; [2021]
    Nyckelord :astroparticle physics; radio detection; high-energy neutrinos; birefringence;

    Sammanfattning : The detection of high-energy neutrinos in the E > O(PeV) range requires newdetection techniques in order to cope with the decreasing flux. The radio detectionmethod uses Askaryan emission to detect these neutrinos. LÄS MER

  4. 3. Application of Twist Symmetry to a Cylindrical Dielectric Waveguide

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

    Författare :Kwinten Van Gassen; [2020]
    Nyckelord :;

    Sammanfattning : The application of higher order symmetry to waveguide design is an active field and is showing evidence of improvement over traditional waveguide designs. There are two forms of higher symmetry: glide symmetry and twist symmetry. LÄS MER

  5. 4. Dissolution and fibre spinning of cellulose from an ionic liquid

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Erika Andersson; [2018]
    Nyckelord :Cellulose; scattering; ionic liquid; dissolution; regenerated cellulose fibre; structure-property relationship; materials chemistry; materialkemi; Chemistry; Technology and Engineering;

    Sammanfattning : Regenerated cellulose fibres can become a sustainable alternative to cotton and polyester in textile applications. One method of producing such is dissolution of cellulose in an ionic liquid (IL) and regeneration through air-gap spinning. LÄS MER

  7. 5. Rotational Diffusion of Cellulose Nanofibrils.

    Kandidat-uppsats, KTH/Mekanik

    Författare :Johan Wärnegård; William Hedén; [2014]
    Nyckelord :;

    Sammanfattning : Cellulose nanofibrils, CNF, is a technical term for the smallest crystalline constituents of wood. Namely particles of cylindrical shape measuring 20-40 nm in diameter and 1-2 um in length. These fibrils display high ultimate tensile strength and a Young's modulus comparable to Kevlar. LÄS MER
