  3. 22. Long-duration energy storage : A technoeconomic comparative analysis with case studies in Mexico

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Nayeli Gallardo; [2020]
    Keywords : ;

    Abstract : While the interest in energy storage has grown in recent years, attention has been largely focused on short-duration systems with lithium-ion batteries. Long-duration (4-24 h) technologies, their business cases, and their potential to contribute to the energy transition have remained largely unexplored. READ MORE

  4. 23. Investigation of the Metal Content in Cress Seedlings fed with increased Concentration of Lead & Iron Solutions

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Nikita Burton; [2020]
    Keywords : Cress; iron; lead; metals; acidified digestion; MP-AES; ICP-MS;

    Abstract : Metals are essential nutrients for plant health, but not all metals are necessary and can sometimes be harmful towards plants depending on factors such as species, elemental composition in the soil and concentration of a metal. Iron (Fe), which is one of the most abundant metals in the earth’s crust is also one the most important nutrients for plant growth, as it is responsible for metabolism. READ MORE

  5. 24. The content, chemical state and accumulation of vanadium in a drill core of Alum shale from Kinnekulle

    University essay from Lunds universitet/Kemiska institutionen

    Author : Niklas Gunnarsson; [2019]
    Keywords : Alum Shale Formation; Alum shale; Kinnekulle; Vanadium; Inorganic chemistry; Oorganisk kemi; Chemistry;

    Abstract : Exploitation of alum shale is a controversial subject in Sweden due to the history of pollution of the environment and groundwater, from past mining industries. The extraction of vanadium from alum shale is no different. Nevertheless the metal is a valuable resource used in tools, building, industries and aerospace materials. READ MORE

  6. 25. Investigation into Melting Characteristics of Hydrogen-Reduced Iron Ore Pellets

    University essay from KTH/Materialvetenskap

    Author : Hedda Pousette; [2019]
    Keywords : Iron Ore Pellets; Sulphur; Phosphorous; Slag; Hydrogen Gas; Järnmalmspellets; Svavel; Fosfor; Slagg; Vätgas;

    Abstract : What kinetic and thermodynamic characteristics are established in a melt of hydrogen-reduced iron ore pellets? The pellets contain self-fluxing slag components which upon melting form an initial slag. Refining capabilities of this slag, such as dephosphorization power, are investigated in a lab-scale vertical furnace. READ MORE
