  1. 1. Effect of Mycorrhizal Inoculation on Growth and Nutrient Uptake by Leek (Allium porrum) fertilized with Inorganic N Combined with Saturated Polonite

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Emmanuel Owusu Boateng; [2023]
    Nyckelord :Phosphorus; Arbuscular Mycorrhiza fungi; Saturated polonite; Nitrogen; Allium porrum; Sustainability; circular economy;

    Sammanfattning : The continuous rise in global population continues to increase the demand for food. Meeting this rise in demand requires an increase in agricultural input, such as applying fertilizers, including phosphorus (P). LÄS MER

  3. 2. Graphene Based Aqueous Ammonium Dual-Ion Batteries

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Arvid Sandberg; [2023]
    Nyckelord :Dual ion batteries; materials science; chemistry; organic polymer;

    Sammanfattning : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. LÄS MER

  4. 3. The geochemical status of the surface water and the sediments in the estuary of the Sangis River, Kalix, Sweden

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

  7. 5. Electrosynthesis of persulfate and hydrogen gas with boron doped diamond as the anode material

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Sandra Shneker; Tsion Abebaw Kebede; Vera Lindbäck; [2022]
    Nyckelord :Boron-doped diamond; persulfate; flow cell; electrosynthesis; current efficiency;

    Sammanfattning : The efficiency of boron-doped diamond electrodes (BDD) has been investigated by electrolysis of an aqueous solution containing sodium sulfate. A Synthesis StarterKit from Condias was used, which contained the BDD anode with an active surface area of 3.14 cm2, and electrosynthesis was performed in a batch mode reactor. LÄS MER
