  1. 1. Utilizing wood ash to stimulate algal growth in mine waters from northern Sweden

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Katelyn Murphy; [2023]
    Nyckelord :acid rock drainage; acid mine drainage; controlled eutrophication;

    Sammanfattning : Acid rock drainage (ARD), caused by the oxidation of sulphide bearing minerals, continues to be an environmental impact of both closed and operational mines, leading to waters with low pH values and high metal concentrations (Park et al., 2019). LÄS MER

  3. 2. Robotic 3D Printing of sustainable structures

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Författare :Tammam Alkhatib; [2023]
    Nyckelord :3D printing; Robotic 3D printing; ABB Robotstudio; Robot simulation; Offline robot programming; 3DP PowerPac;

    Sammanfattning : This bachelor thesis aims to integrate and evaluate a 3D printing robotic cell at the SmartIndustry Group – SIG lab at Linnaeus University (LNU).A sustainable structure consisting of wood fiber polymer composites was 3D printed withan industrial robot. Sustainable 3D printing material can be recycled or burned for energyafterwards. LÄS MER

  5. 4. Laser Scattering for Fast Characterization of Cellulose Filaments

    Kandidat-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Alexandra Konstantinidou; Saga Holmström; Susanna Hellberg; [2022]
    Nyckelord :Cellulose nanofibrils; Fibers; Sustainable development; Bio-based material; Characterization; Microscale; Microscopy; Small-angle light scattering; Laser diffraction; Cellulosananofibriller; Fiber; H˚allbar utveckling; Biobaserade material; Karakterisering; Mikroskala; Mikroskopi; Ljusspridning; Laserdiffraktion;

    Sammanfattning : Cellulosananofibriller (CNFs) hör till naturens mest fundamentala byggstenar och förser naturliga material, såsom den yttre cellväggen i trä, med en otrolig styrka och styvhet. Genom att imitera träets arkitektur öppnas möjligheter upp för tillverkning av nya, biobaserade och lättviktiga strukturella material med mekaniska egenskaper som överskrider de för glasfiber, metaller och legeringar.

  7. 5. Assessment of promoter regulation in Pseudomonas putida using GFP and flow cytometry

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi

    Författare :Luka Cululejevic; [2022]
    Nyckelord :applied microbiology; Pseudomonas putida; promoter characterization; aromatic compounds; vanillin; guaiacol; Biology and Life Sciences;

    Sammanfattning : Lignin is found in all biomass and is an abundant natural source of aromatic compounds. It has the potential to serve as a renewable raw material for a variety of chemicals currently derived from fossil fuel sources such as muconic acid, an important platform chemical. Kraft lignin is a waste stream from the pulp and paper industry. LÄS MER
