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

    University essay from KTH/Tillämpad fysik

    Author : Xinyi Wei; [2023]
    Keywords : Lignin; lignin-based elastomer; nanocomposites; Lignin; ligninbaserad elastomer; nanokompositer;

    Abstract : 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. Methods and Potentials of Kraft Lignin Esterification

    University essay from KTH/Fiber- och polymerteknologi

    Author : Taoran Xu; [2023]
    Keywords : Kraft lignin; acetylation; fatty acid esterification; quantitative 31P NMR; lignin nanoparticles; Kraftlignin; acetylering; fettsyreesterifiering; kvantitativ 31P NMR; lignin nanopartiklar;

    Abstract : Lignin, en av huvudkomponenterna i lignocellulosabiomassa, utgör en stor mängd av sidoströmen från massaindustrin. Lignin är aromatiska makromolekyler som förekommer i rikliga mängder i naturen och uppvisar unika antioxidant-, uv-skyddande, anti-ultravioletta, antikorrosiva och antimikrobiella egenskaper, etc. READ MORE

  4. 3. Development of magnetic lignin nanoparticles from low-molecular-weight eucalyptus and spruce lignin fractions

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Anna Wessén; Eliot Diklev; Lejla Al-Tamimi; [2020]
    Keywords : Magnetic nanoparticles; Hardwood; Softwood; Self-assembly; Lignin;

    Abstract : Lignin is one of the most common biopolymers in the world. Together with cellulose andhemicellulose it constitutes the fibers in the wood. It has a high molecular weight due to its complexstructure consisting of crossed-linked phenolic monomers and is concatenated with different types ofcarbon and ether bonds. READ MORE

  5. 4. The impact of the pulping process on the properties of lignin nanoparticles

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Kristoffer Guthenberg; [2020]
    Keywords : Lignin; Nano; Nanoparticles; Extraction; Kraft; Organosolv; Softwood; Properties;

    Abstract : Lignin valorization is a key component of the total utilization of biomass in the biorefinery industry. Lignin has seen some use in several different applications, but a breakthrough is still yet to happen, and there is still a need to find more areas where lignin can be used as an alternative feedstock or as the main component.

  6. 5. Optical Characterization of Lignin Nanoparticles

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Kristoffer Linder; [2020]
    Keywords : lignin; nanoparticles; nanoparticle; optical characterization; optical properties; surface plasmon resonance;

    Abstract : Lignin is one of the main components of wood and plants that acts as a kind of glue providing mechanical strength. It is a main polymer component composed from three phenolic structures, i.e. p-hydroxyphenyl (H), guaiacyl (G) and syringyl (S) units. READ MORE
