  1. 21. New Manufacturing Technology for Volume Optimization of Parts : Amorphous Metal Moulding

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Andreas Jonsson; [2021]
    Nyckelord :amorphous metal; metallic glass; amorphous metal moulding; amorfa metaller; metalliskt glas; amorf metallgjutning;

    Sammanfattning : Amorphous metals have gained a lot of attention since its introduction in the 1960s, and the usage and knowledge are growing rapidly. The underlying reason for this trend is the desire to utilize these materials unique combinationof properties. LÄS MER

  3. 22. Selective recovery of lithium from thermally pretreated Li-ion batteries by the leaching process

    Master-uppsats, KTH/Kemiteknik

    Författare :Srija Balachandran; [2020]
    Nyckelord :Electric vehicles; Li-ion batteries; a combined method of recycling; pyrolysis; incineration; water leaching; Elektriska fordon; Li-ion-batterier; en kombinerad metod för återvinning; pyrolys; förbränning; vattenlakning;

    Sammanfattning : LIBs have become an ideal choice in the EVs batteries and stationary storage applications due to their invaluable advantages. The demand for LIBs is projected to increase due to the growth in the sale of EVs. LÄS MER

  4. 23. An investigation of the interactions between clay nanoplatelets in the presence of monovalent and divalent salts, as well as cationic peptides utilising atomistic molecular dynamics

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Mona Koder Hamid; [2020]
    Nyckelord :clay; molecular dynamics simulations; physical chemistry; fysikalisk kemi; theoretical chemistry; teoretisk kemi; Chemistry;

    Sammanfattning : Clays are negatively charged nanoplatelets with a layered silicate structure. It has been observed from small angle X-ray scattering measurements, and coarse-grained molecular dynamics simulations (CG-MD) that clay nanoplatelets are able to form stacks, known as tactoids, in the presence of divalent or multivalent counterions [8, 5].

  5. 24. Influences of palladium ceramics on valuable metal losses to a PbO-SiO2-Sb2O3 based silver smelting slag.

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Per Kautto; [2020]
    Nyckelord :palladium ceramics; silver smelting slag; PbO-SiO2-Sb2O3;

    Sammanfattning : Silver and palladium can be found in the so called palladium-ceramics which comes from catalyst production. These valuable metals needs to be recovered from these wastes in order to further increase both the environmental and economic sustainability of our society. LÄS MER

  7. 25. Möjligheten att minska metallhalten i lakvatten med sulfatreducerande bakterier

    Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Författare :Sofie Sunesson; [2020]
    Nyckelord :Metals; Landfill; Leachate; SRB; Precipitation; Sulfide; Applied microbiology; Teknisk mikrobiologi; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : Anaerobic treatment of landfill leachate using sulphide precipitation was tested at pilot scale for the purpose of heavy metal removal. The emission of leachate is heavily regulated by Swedish authority and the overall concentrations of heavy metals is expected to rise as landfills contain less organic matter. LÄS MER
