  1. 1. Syntetiskt pärlemor : Producerat via in situ-kristallisation

    Master-uppsats,

    Författare :Pontus Blomberg; [2023]
    Nyckelord :Biomineralisation; Aragonite; Calcium; Carbonate; CaCO3; CNC;

    Sammanfattning : This thesis describes a sequence of experiments which have been performed with the intention to produce synthetic nacre. Synthetic nacre is a biomimetic material based on nacre, a material which can be found in mollusc shells. Nacre is a nanocomposite which has improved mechanical properties compared to the principal component aragonite (95% wt%). LÄS MER

    Sammanfattning : During the global pandemic of coronavirus, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak, the world was desperately searching for simpler yet more effective solutions to stop the spread of coronavirus (COVID-19). Since no one was prepared for the fast spread of such a contagious virus, there was a shortage of proper protective solutions to stop the spread. LÄS MER

  4. 3. Glyoxylic-Modified Lignin for Synthesis of Smart Elastomer and Composite Materials

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Xinyi Wei; [2023]
    Nyckelord :Lignin; lignin-based elastomer; nanocomposites; Lignin; ligninbaserad elastomer; nanokompositer;

    Sammanfattning : Sustainable development has become a global goal and the utilization of bioresources is a key way to achieve this crucial goal. Glyoxylic acid-functionalized lignin (GA-lignin) is one of the novel lignin derivatives extracted from beech wood (hardwood) and has great potential to be an industrially important bioresource.

  5. 4. Användning av den vattenbaserade emulsionspolymeren för utveckling avspecifika egenskaper hos tegel och betong: syntes och karakterisering

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Shahab Nasr; [2022]
    Nyckelord :Water-based acrylic styrene emulsion polymerization; Coating; Nanocomposites; Concrete; Brick;

    Sammanfattning : Improvement properties of building materials are essential. In this dissertation thesis, the main concern had been on synthesizing a new resin to improve the properties of concrete and brick. Solvent-based polymers have been used for many years to improve the quality of building materials. LÄS MER

  7. 5. 2D-material nanocomposites with nonlinear optical properties for laser protection

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Nils Ross; [2021]
    Nyckelord :optical power limiting; OPL; laser protection; nanocomposites; 2D-materials; graphene oxide; MXene; Ti3C2; melting gel; graphene; two-dimensional materials; nonlinear optical properties; NLO; spectroscopy;

    Sammanfattning : Lasers are increasingly used for a wide range of different applications for both civil and military purposes. Due to the distinct properties of laser light, use of lasers often comes with a risk of damage to the human eye and other optical sensors. Therefore, an effective laser protection is needed. LÄS MER
