  1. 1. Primary Study of the Phase Relationship in the MgO-"V2O3" System at 1873 K and pO2=10-11 atm

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

    Author : Line Larby; Annie Lundberg; [2018]
    Keywords : ;

    Abstract : Vanadium can be found in some iron ores as an impurity. Since vanadium is a valuable alloy element there lies an interest in development of a stable and economic way for extraction of it. For this, knowledge about the thermodynamics behind the V-O system combined with other elements, like Mg, is indispensable. READ MORE

  2. 2. Creating nanopatterned polymer films for use in light-emitting electrochemical cells

    University essay from Umeå universitet/Institutionen för fysik

    Author : Thomas Moberg; [2018]
    Keywords : Thermal nanoimprint lithography; soft stamp; intermediate polymer stamp; Light-emitting electrochemical cell; LEC; Super Yellow; polystyrene; poly ethylene oxide ; nanopattern;

    Abstract : Thermal nanoimprint lithography (T-NIL) is a cheap and fast technique to produce nanopatterns in polymeric materials. It creates these patterns by pressing a stamp down into a polymer film that has been heated above its glass transition temperature. READ MORE

  3. 3. Phase field modelling of LLZO/LCO cathode-electrolyte interfaces in solid state batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Michele Riva; [2018]
    Keywords : LLZO; LCO; phase; field; phase-field; phasefield; solid; state; solid-state; solidstate; battery; batteries; sintering; model; modelling;

    Abstract : This work describes two phase field models for the simulation of the interface evolution between a LiCoO2 cathode (LCO) and a Li7La3Zr2O12 solid electrolyte (LLZO) in a Li-metal/LLZO/LCO battery during high temperature sintering. In these conditions atomic species tend to diffuse into the opposing material, creating an intermediate layer of mixed composition which resists the movement of lithium ions. READ MORE

  4. 4. Study of leaching behavior of tin in Zinc-clinker and Mixed Oxide

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Olle Bertilsson; [2018]
    Keywords : Leaching; tin; Sn; Zn-clinker; Mixed Oxide; sulfuric acid; Zn; residue; H2SO4; Boliden;

    Abstract : Due to the increasing usage of Sn in different electronics, such as solders and in touchscreens, together with Boliden Rönnskärs increased intake of electronic waste as a secondaryraw material, a Zn-containing product called Zn-clinker has increasing amounts of Sn. TheZn-clinker is shipped to Boliden Zn-smelter in Odda, where the Zn-clinker is mixed in withcalcine (roasted concentrate) and leached in several steps. READ MORE

  5. 5. Strukturkalkens inverkan på såbäddens aggregategenskaper : en studie inriktad på strukturkalkning av lättleror

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Hjalmar Tindberg; [2018]
    Keywords : strukturkalk; kalk; lättlera; lerjord; aggregatstabilitet; marklära; limestone; structure lime; aggregate stability; loamy clay soil;

    Abstract : Kalkning är en åtgärd som bidrar till att förbättra åkerjordens beskaffenhet och höja grödors avkastningspotential. Det finns flera olika typer av kalkning. Ett exempel är traditionell kalkning som syftar till att höja pH i jorden genom tillförsel av kalkstensmjöl. READ MORE
