  1. 1. Barium in the O horizon of soils near Sundsvall, northern Sweden : From local minerals or from anthropogenic emissions?

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

    Författare :Mattias Åsberg Gencturk; [2023]
    Nyckelord :Barium; soil; organic horizon;

    Sammanfattning : Concentrations of potentially toxic metals in surface soils are important to investigate before building new residential areas. Prior to development of a residential area in Sundsvall, northern Sweden, it was observed that barium (Ba) concentrations in the soil at the site exceeded the guideline value of 200 mg kg-1 outlined by the Swedish Environmental Protection Agency.

  3. 2. Aluminum levels in the O-horizon of soils near Sundsvall, Sweden : Are levels of Al elevated due to smelter emission?

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

    Författare :Mattias Sundin; [2023]
    Nyckelord :Aluminium; Smelter emissions; O-horizon; Al concentration; Scots’ pine needles;

    Sammanfattning : Aluminum (Al) is a potentially toxic element for humans, animals, and plants. Al emitted from smelter plants is one source of Al that may be responsible for increased exposure to humans and the environment. LÄS MER

  4. 3. On the stability of current collectors in high-voltage lithium-ion batteries containing LiFSI electrolytes

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Oorganisk kemi

    Författare :Kevin Carlö; [2023]
    Nyckelord :LiFSI; high-voltage; anodic dissolution; corrosion; aluminum; current collector; electrolyte; battery;

    Sammanfattning : The increasing energy demand requires a transition from fossil fuels to renewable resources. Lithium-ion batteries (LIBs) offer a promising solution as efficient energy storage devices. However, the aluminum current collector (CC) in LIBs is susceptible to anodic dissolution above 3 V vs. LÄS MER
