  1. 16. Synergistic fire- and mechanical effect of biochar and ammonium polyphosphate in epoxy composite

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Anton Olausson; Ludvig Jönsson; [2023]
    Keywords : Ammonium polyphosphate; Biochar; Composite; Epoxy; Synergistic effect;

    Abstract : Polymer composites are used in a varying extent and are challenging the use of traditional materials due to the push towards sustainable development. They have replaced steels and aluminum alloys in applications. READ MORE

  3. 17. Machine Learning of Laser Ultrasonic Data to Predict Material Properties

    University essay from Linköpings universitet/Statistik och maskininlärning

    Author : Filip Tuvenvall; [2023]
    Keywords : Machine Learning; Laser Ultrasonics; Material Properties; Steel; Hardness of Steel;

    Abstract : The hardness of steel is an important quality parameter for several industrial applications. Conventional mechanical testing is used in quality testing for material hardness and the method is time-consuming, can cause material mix-ups, and results in material waste. READ MORE

  4. 18. Experimental studies of radiation damage in uranium nitride

    University essay from KTH/Fysik

    Author : Maria Giamouridou; [2023]
    Keywords : uranium nitride nuclear fuel; advanced nuclear fuel; uranium nitride fabrication; uranium nitride characterisation; Spark Plasma Sintering; proton irradiation; irradiation damage; TANDEM accelerator; irradiation induced cracking; irradiation induced hardening; irradiation induced swelling; hydrogen implantation; dislocation loops; kärnbränsle av urannitrid; avancerat kärnbränsle; tillverkning av urannitrid; karakterisering av urannitrid; Spark Plasma Sintering; protonbestrålning; strålningsskador; TANDEM-accelerator; strålningsinducerad sprickbildning; strålningsinducerad härdning; strålningsinducerad svällning; väteimplantation; dislokationsloopar;

    Abstract : The effect of proton (H+) irradiation on uranium mononitride (UN) and UN compositefuel with 10 at.% ZrN (UN10at%ZrN) was examined. Protons of 2 MeV with fluences of1E17, 1E18, 1E19 and 1E20 ions/cm2 were accelerated towards the fabricated samples in orderto investigate the evolution of the micro-structure. READ MORE

  5. 19. CO2 Sequestration by Bio-Accelerated Silicate Weathering

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Tora Uebel; Elisabeth Odelius; [2023]
    Keywords : enhanced silicate weathering; microorganisms; negative emission technology; CO2 emissions;

    Abstract : Human-caused emissions of CO2 and other greenhouse gases are an established reason for the climate changes that affect planet Earth. Negative emission technologies (NETs), for example, bio-accelerated silicate weathering bioreactors, seek to capture and store carbon from the atmosphere. READ MORE

  6. 20. The transition of reaction-to-fire behavior from biomass to corresponding biochar

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Jacob Johansson; [2023]
    Keywords : biochar; biomass; heat release rate; reaction-to-fire;

    Abstract : As of now, the environmental issue is very topical and there is also an underutilization of different biological material where these can be used in ways that are typically not thought of. One way to increase the degree of utilization is to convert various biomasses such as natural rubber, olive pits, wood chips, and reed pellets into biochar. READ MORE
