  1. 6. Optical Emission Spectroscopy Pulse Distribution Analysis on Steel Production Samples : Accuracy, sample variation, spread in different samples and steel grades/routes

    University essay from KTH/Materialvetenskap

    Author : Paulo Urrea Molina; [2023]
    Keywords : ;

    Abstract : This thesis work aimed to contribute to the development of online characterization techniques for non-metallic inclusions in steelmaking. The study focused on assessing the precision and accuracy of the optical emission spectroscopy pulse distribution analysis (OES/PDA) technique using asreference light optical microscope (LOM) and scanning electron microscope(SEM).

  3. 7. Petrography of impactites from the Dellen impact structure, Sweden

    University essay from Lunds universitet/Geologiska institutionen

    Author : Robert Mroczek; [2023]
    Keywords : Dellen; Impact; structure; magnetite; apatite; shock waves; shock-metamorphic; features; Impactite; petrography; scanning electron microscope; SEM; geology; Earth and Environmental Sciences;

    Abstract : Identification and characterization of shock-metamorphic features in hypervelocity impact craters is important for our understanding of how shock waves interact with geologic materials and how impact craters form, which in turn is essential to our understanding of what role impact cratering played in the development of our solar system. Of particular interest are accessory minerals like apatite, which contains various volatiles that can affect the atmosphere of a body, or magnetite whose magnetic properties constitute a remote sensing indicator which allows us to study and understand the internal structures of distant bodies.

  4. 8. Geological characterization of rock samples by LIBS and ME-XRT analytical techniques

    University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

    Author : Nsioh Elvis Nkioh; [2022]
    Keywords : geological characterization; analytical techniques; LIBS; ME-XRT; SEM; element maps; SEM-EDS; secondary electrons; rock samples; automated ore microscopy; SEM-Zeiss Merlin; element weight percentages; element oxide percentages; scanning techniques; analytical methods; laser induced breakdown spectrometry; multi energy x-ray transmission; scanning electron microscope; carbon coating; mineralogical classification; element composition; rock chemistry; rock chemical composition;

    Abstract : One of the major challenges in earth sciences and mineral exploration has been to determine with high accuracy and at a fast rate the elemental composition as well as the general chemistry of a rock sample. Many analytical techniques e.g. READ MORE

  5. 9. Optimization of hot strip drawing test methodology for hot forming of aluminium alloys

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

    Author : Rabia Arshad; [2022]
    Keywords : Hot forming of aluminium; friction; high temperature lubrication; strip draw; wear.;

    Abstract : The development of lightweight design for automotive applications has lasted for many years and is still increasing. Vehicles with light structures use less fuel, emit less CO2, and are better for the environment. READ MORE

  6. 10. Laser Scattering for Fast Characterization of Cellulose Filaments

    University essay from KTH/Fiber- och polymerteknologi

    Author : Alexandra Konstantinidou; Saga Holmström; Susanna Hellberg; [2022]
    Keywords : 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;

    Abstract : 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.
