  1. 1. Property prediction of super-strong nanocellulose fibers

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

    Författare :Maria Abada; Elin Fossum; Louise Brandt; Anton Åkesson; [2020]
    Nyckelord :Cellulose nanofibril CNF ; Spinning; Flow-stop; Flow-focusing; Mechanical properties; Carboxymethylation; TEMPO-oxidation;

    Sammanfattning : The innovative technology behind production of strong biofilaments involves the process of spinning filaments from nanoparticles extracted from wood. These nanoparticles are called cellulose nanofibrils (CNFs). LÄS MER

  3. 2. Mechanical and Thermal Characterisation of Polymer Films Exposed to Filling Products

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

    Författare :Erik Vu; [2019]
    Nyckelord :polymer technology; polymerteknologi; Technology and Engineering; Chemistry;

    Sammanfattning : Knowledge on how polymeric materials changes or is affected when exposed to products is of interest and importance for many commercial applications. Understanding the product interaction on packaging materials is the key to preventing errors and increasing the quality of products. LÄS MER

  4. 3. Investigating the triolein/aqueous interface and Thermomyces lanuginosa lipase activity

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Veronika Tolevska; [2018]
    Nyckelord :Spectroscopic ellipsometry; SAXS; lipase activity; interfacial activation; triolein aqueous interface; physical chemistry; fysikalisk kemi; Chemistry;

    Sammanfattning : The triglyceride/ aqueous interface has an important role in many processes, e.g. lipase activity. Lipase is responsible for the degradation of triglycerides to smaller components, such as fatty acids. 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. Fracture mechanics and damage modeling of injection molded high density polyethylene

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Hållfasthetslära

    Författare :Isabelle Wahlström; [2018]
    Nyckelord :Polymer; HDPE; damage; fracture mechanics; SAXS; WAXS; DIC; virtual engineering; Technology and Engineering;

    Sammanfattning : For many applications a fracture is a disaster, leading to failure of the application and thus its usefulness. However, when it comes to the opening of a food and beverage package, fracture is a necessity. At Tetra Pak, food and beverage packages are produced to make food safe and available everywhere. LÄS MER
