  1. 11. Stability improvement to a ruthenium catalyst for partial oxidation of methane

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Melker Axelsson; [2023]
    Nyckelord :catalysis; reaction engineering; kinetics; partial oxidation; chemical engineering; Technology and Engineering;

    Sammanfattning : Catalytic partial oxidation of methane (CPOM) is an energy-efficient alternative to steam reforming, the currently prevailing method for energy production from natural gas. Hulteberg Chemistry & Engineering AB has developed a catalyst for the partial oxidation of methane into syngas, for use in solid oxide fuel cells. LÄS MER

  3. 12. Image analysis of Light Optical Microscopy (LOM) images of metallurgical samples

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :David Håkansson; [2023]
    Nyckelord :;

    Sammanfattning : Processing metals in different ways often requires stringent quality control to ensure the quality of the processed metal. This master's thesis aims to develop methods for evaluating the quality of metals via image analysis rather than inspecting images manually as it traditionally has been done. LÄS MER

  4. 13. Lead Concentrations in Indoor Dust : Differences Between Indoor Shooting Ranges and Assumed Non-Lead Contaminated Sites

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Lena Brolin; [2023]
    Nyckelord :Ammunition; environmentally friendly ammunition; lead; lead at indoor shooting ranges; lead exposure.;

    Sammanfattning : A projectile which missed its target and falls into the bullet trap at the end of the shooting range might not be viewed as dangerous. Yet, hazardous fumes and fine metal fragments from the bullet might contaminate the users of the shooting range. LÄS MER

  5. 14. Sustainability demands on internal and external providers of IT

    Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Emma Lenman; Ida Appelgren; [2023]
    Nyckelord :sustainable IT; sustainability; IT; green IT; data governance; energy efficient; greenhouse gas emissions;

    Sammanfattning : The use of IT in companies is constantly expanding, and therefore, so is the energy consumption and carbon footprint from IT. If companies do not take steps towards more sustainable IT usage, the footprint will continue to expand, toxic metals will be used in hardware and the usage of world resources will not become more circular.

  7. 15. Metals for energy storage : For hydrogen and power generation

    Master-uppsats, Linköpings universitet/Konstruktionsmaterial

    Författare :Oscar Torsteinsrud; Mattias Reijm; [2023]
    Nyckelord :Metals; Energy Storage; Round Trip Efficiency; Aluminum; Boron; Magnesium; Silicon; Zinc;

    Sammanfattning : With an increase in energy demand and a transition from conventional fossil-driven energy generation, the world is facing a major challenge. This transition implies more intermittent energy sources whose reliance varies widely with time. To deal with this challenge, energy storage is one part of the solution. LÄS MER
