  1. 1. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Rasmus Staaf; [2024]
    Nyckelord :artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

    Sammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

  3. 2. Incorporation of Plasticizers through Refining into Wood Pulp : A Potential Route For Bio-based Thermoplastic Materials

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Victor Eric Pierre Chartrain; [2023]
    Nyckelord :Cellulose; Paper; Plasticizer; Mechanical Refining; Cellulosa; Papper; Mjukgörare; mekanisk bearbetning;

    Sammanfattning : Fibers are interesting materials alternative to replace conventional fossil-based plastics, as they are bio-based and do not lead to CO2 emissions. Due to their limited ductility, it is difficult to use them to make complex three-dimensional shapes. LÄS MER

  4. 3. Fabrication of battery separator by coating with sulfonated cellulose nanofibrils on kraft paper and inkjet paper substrates : Tillverkning av batteriseparator genom bestrykning med sulfonerad cellulosananofibriller på kraft papper och bläckstråle papper substrat

    Master-uppsats, Karlstads universitet/Avdelningen för kemiteknik

    Författare :Forat Alshogran; [2023]
    Nyckelord :modified nanocellulose; coating; battery separator; contact angle; mechanical strength; permeance; ionic conductivity;

    Sammanfattning : Modified nanocellulose have distinctive qualities and have drawn a lot of interest from a variety of fields. It is a natural, sustainable product that is manufactured from plant-based materials like wood and other renewable resources. It is also biodegradable. LÄS MER

  5. 4. "Undantaget": Reinterpreting (a) dwelling for (an) elderly

    Uppsats för yrkesexamina på avancerad nivå, KTH/Arkitektur

    Författare :Emmie Olson; [2023]
    Nyckelord :dwelling; housing; elderly; timber; wood; vernacular; post-and-plank; Halland;

    Sammanfattning : In the upcoming years, the proportion of elderly within the population will increase significantly (SCB, Socialstyrelsen). The share of aged is already, and will increasingly be, noticeably higher in municipalities on the countryside compared to in the cities. 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.
