  1. 1. 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.

  3. 2. 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

  4. 3. Optical characterisation of AAO/CsPbBr3 perovskite nanocomposites

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Klára Nováková; [2021]
    Nyckelord :perovskite; scintillator; optoelectronics; semiconductor; X-ray detection; Physics and Astronomy;

    Sammanfattning : Direct bandgap metal lead halide perovskites offer promising optoelectronic properties desirable in a wide range of applications including photodetection. However, the incomplete and poor understanding of the photophysical processes taking place in these materials, along with their poor stability, is the bottleneck for optimisation and further development of metal halide perovskite devices.

  5. 4. 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

  7. 5. Flexible and recyclable electronics made from nanoreinforced silk

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Marek Bukovský; [2020]
    Nyckelord :Wearable electronics; flexible electronics; silk fibroin; MXene; nanocomposites; Bärbar elektronik; flexibel elektronik; silkes fibriller; MXene; nanokompositer;

    Sammanfattning : Forskningsområdet för bärbar elektronik är fortfarande relativt ungt och det finns ett stort behov av utveckling av nya material inom området. Olika typer av kompositer är mycket intressanta och de ska uppvisa såväl hög hållfasthet som goda ledande egenskaper. LÄS MER
