  1. 16. 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

  3. 17. Iron Pieces from The Copper Wreck : An archaeometallurgical analysis of iron bars, billets and osmund iron found in Gdansk, Poland

    University essay from KTH/Materialvetenskap

    Author : Mikael Ghaysari; Benjamin Tiberghien; Maximilian Åkerblom Jonsson; [2022]
    Keywords : The Copper wreck; W5; Miedsiowiec; Osmund; Slag analysis; SEM; EDS; LOM; Medieval iron production; Blast furnace; Indirect reduction; Direct reduction; Kopparvraket; W5; Miedsiowiec; Osmund; Slagg; SEM; EDS; LOM; Medeltida järnproduktionen; Masugn; Indirekt reduktion; Direkt reduktion;

    Abstract : The topic of osmund iron is of great interest in both historical and metallurgical perspective. Between the 14th and the 17th century osmund iron was exported extensively from Sweden but it has been difficult to characterize and confirm what exactly osmund iron is. READ MORE

  4. 18. Performance Analysis of Environmentally Adaptable Grease in Large open gears

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

    Author : Victor Ogunmoye; [2022]
    Keywords : Grease; Large open gears; tribology; lubrication; wear; friction; Twin disc; Material surface;

    Abstract : Environmentally adaptable grease (EAG) lubricants are essential in applications with loss lubrication due to their biodegradable nature. This is because the lubricants could be expelled into the environment during usage in some applications e.g., marine and mining applications. READ MORE

  5. 19. Continuous Hydrothermal Co-liquefaction of Biomass : An experimental study on the effects of fuel mixing on the composition and yield of biocrude and hydrochar

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Simon Fridolfsson; [2022]
    Keywords : HTL; TGA; SEM EDS; Co-liquefaction effects; GROT; Kraft lignin; Microalgae;

    Abstract : An experimental study on the effect of fuel mixing on the products resulting from hydrothermal liquefaction (HTL) was conducted. The feedstocks used were kraft lignin (KL), GROT (GT) and microalgae cultivated in wastewater (MA). Three sets of mixtures were prepared, each containing two types of feedstocks with a 1:1 ratio: KLGT, MAKL, and MAGT. READ MORE

  6. 20. The Fe-oxides (mineralogical, chemical, and textural) variation in the Leveäniemi deposit using micro-analytical tools for unraveling of primary features and metamorphic recrystallisation

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

    Author : Adrian Larsson; [2022]
    Keywords : Leveäniemi; Magnetite; Hematite; Iron oxides; Iron oxide apatite;

    Abstract : The Leveäniemi iron oxide apatite (IOA) deposit, mined by LKAB, is located in Norrbotten, northern Sweden. The deposit has a partially more complex mineralogy than the neighbouring and more famous IOA deposits of Kiirunavaara and Malmberget. READ MORE
