  1. 16. Synthesis and Characterization of NCN Pincer Nickel Complexes

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Joel Klarén; [2023]
    Nyckelord :Pincer complexes; Nickel; organometallic chemistry; synthesis; NCN Pincer Nickel Complexes; organic chemistry; Chemistry;

    Sammanfattning : In this work, a series of nickel NCN complexes and ligands have been synthesized with the goal of determining whether they can perform so-called CO2-insertion reactions into Ni-C bonds. So far, only the synthesis of the Ni-Br precursor complexes to the previously mentioned Ni-C complexes have been synthesized. LÄS MER

  3. 17. Fällning av Råmaterial för Batteriåtervinning

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Aran Nur; Axel Bergvall; Gustaf Forsberg; Nemrit Kaur; [2023]
    Nyckelord :Battery recycling; Precipitation; Sustainability; Metal recovery; Simultaneous crystallization;

    Sammanfattning : This report explores simultaneous crystallization in multicomponent solutions to intensification of metal recovery in lithium-ion batteries. The main focus is to evaluate and compare the efficiency of sodium hydroxide and sodium carbonate as precipitating agents in recovering cobalt, nickel, manganese and lithium. LÄS MER

  4. 18. Water quality improvement of highway runoff by the filter material D-Rainclean : A five-month field trial

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :William Gulding; [2023]
    Nyckelord :Adsorption; D-Rainclean; metal removal; Reactive filter; stormwater treatment;

    Sammanfattning : Highway runoff and its pollutants are of growing concern. These pollutants require treatment as their concentration often are increased. A common removal method is the use of sedimentation ponds that removes particulates through gravity. LÄS MER

  5. 19. Näringsämnen och metaller i sediment och blåmusslor från Hanöbukten - En analys av marin miljöpåverkan från massabruk

    Master-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Elvira Källberg; [2023]
    Nyckelord :Föroreningar; massabruk; blåmusslor; sediment; Earth and Environmental Sciences;

    Sammanfattning : The pulp industry is important for creating sustainable paper products and for the Swedish economy. However, the industry has historically polluted marine environments through its emissions. This study aims to analyse the effects of the pulp mill Södra Cell Mörrum on the marine recipient Hanö Bay in the southern Baltic Sea. LÄS MER
