  1. 1. Precipitation analysis in bearing steel Hybrid 60

    Master-uppsats, KTH/Materialvetenskap

    Författare :Rebecca Rosén; [2023]
    Nyckelord :martensitic steel; secondary hardening; precipitation; PRISMA; martensitiskt stål; sekundärhärdning; utskiljning; PRISMA;

    Sammanfattning : New materials are always being developed to get the best properties possible where needed. The way to create these materials and test them is also developing. When it comes to high-strength steels, a martensitic microstructure is a common choice. LÄS MER

  3. 2. Water-based Synthesis of Superparamagnetic X-ray Fluorescent Contrast Agents

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Daniel Cortés García; [2022]
    Nyckelord :Nanoparticles; SPIONs; XFCT; co-precipitation.; Nanopartiklar; SPIONs; XFCT; samfällning;

    Sammanfattning : Nowadays, nanomedicine is one of the most important application areas fornanoparticles (NPs), where the design and synthesis of new hybrid nanostructures have attracted much interest, when combining properties and functionalities from different constituents. For example, they have been extensivelyused for dual-mode imaging. LÄS MER

  4. 3. Critical elements scavenged by secondary gypsum and HFO : Determined by sequential extraction combined with mineralogical studies

    Master-uppsats, Luleå tekniska universitet/Geovetenskap och miljöteknik

    Författare :Emma Flodin; [2022]
    Nyckelord :Geochemistry; gypsum; HFO; adsorption; scavenged; critical elements; beryllium; Yxsjöberg; mine waste; Sequential extraction; XRD; SEM-EDS;

    Sammanfattning : The demand for metals is great for the purpose of developing green technologies, and EU has listed 30 metals and minerals that are of critical importance for the maintenance and evolving of today’s society, so called critical materials. However, mining of raw materials generates mine waste which can have adverse effect on human health, ecosystems, and surrounding areas. LÄS MER

  5. 4. Distribution and mobilization of heavy metals at an acid mine drainage-affected region, South China

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Chen Luo; [2020]
    Nyckelord :acid mine drainage; arsenic; cadmium; geochemical modeling; heavy metals; lead; principal component analysis;

    Sammanfattning : Dabaoshan Mine Site (DMS) is the biggest polymetallic mine in South China. The Hengshi River receives acid mine drain (AMD) waste leaching from the tailings pond and run-off from the treatment plant which flows into the Wengjiang River, Beijiang River, before discharging into the Pearl River.

  7. 5. Geochemical Investigation of Arsenic in Drinking Water Sources in Proximity of Gold Mining Areas within the Lake Victoria Basin, in Northern Tanzania

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Enrico Lucca; [2017]
    Nyckelord :;

    Sammanfattning : Access to safe drinking water is a challenge for rural communities in many developing countries. Drinking contaminated water endangers human health and impairs social and economic development. Arsenic (As) is a metalloid widely distributed into the environment and is highly toxic in its trivalent inorganic form. LÄS MER
