  1. 1. Drought resistance of Ectomycorrhizal fungi in the Suillus genus

    Master-uppsats, SLU/Dept. of Forest Mycology and Plant Pathology

    Författare :Patricia Salén; [2024]
    Nyckelord :Ectomycorrhiza; drought; Suillus;

    Sammanfattning : Rising instances of drought are causing more tree seedling fatalities post-nursery outplanting. In the face of climate change, fostering resilient forestry practices is imperative for preserving the health and functionality of our forests. LÄS MER

  3. 2. Evaluation of different block-copolymer coatings of iron oxide nanoparticles by flash nanoprecipitation

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Felix Bogdan; [2023]
    Nyckelord :Nanopartiklar; organisk katalysator; ROP; block-sampolymerer PL G A; oljesyra IONPs; Nanoparticles; organic catalyst; ROP; block-copolymers PL G A; oleic acid IONPs;

    Sammanfattning : Nanopartiklar (NP) erbjuder unika möjligheter för medicinska tillämpningar, inklusive kontrollerad frisättning av cancerläkemedel, användning som bildkontrast vid avbildningsprocedurer eller hypertermisk behandling av cancerceller. Flash nanoprecipitation (FNP) producerar NPs för att kombinera dessa tillämpningar i en snabb, billig och skalbar beläggningsprocess. LÄS MER

  4. 3. Investigation on the natural indigo dye for cotton fabric by using supercritical carbon dioxide

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

    Författare :Ryoi Takamatsu; [2023]
    Nyckelord :Dyeing; supercritical carbon dioxide; indigo; cotton; eco-friendly; textile;

    Sammanfattning : Concerns about the environmental impact of the textile industry are increasing, and there is an urgent need to develop and implement sustainable technologies. In particular, the environmental impact of dyeing, which emits a large amount of wastewater and chemicals, is one production process that needs to be resolved. LÄS MER

  5. 4. Service life study of environmentally friendly lubricants.

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Sammanfattning : Environmentally friendly lubricants are in demand in response to the rising concerns and restrictive legislation that surround the use of mineral oil lubricants. One area of importance is understanding the service life of the environmentally friendly base oils of these non-toxic, biodegradable and renewable alternatives. LÄS MER

  7. 5. 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.
