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

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Abstract : 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. READ MORE

  3. 2. Environmental transformation and dissolution of Cobalt- and Nickel-based Nanoparticles in Presence of Eco-corona Biomolecules

    University essay from KTH/Yt- och korrosionsvetenskap

    Author : Anher Saeed; [2021]
    Keywords : Nanoparticles; Cobalt; Nickel; Eco-corona biomolecules adsorption; Metal dissolution; Nanopartiklar; Kobolt; Nickel; Biomolekyler adsorption; Metallfrisättning;

    Abstract : Den ökande trenden med att använda tillverkade nanopartiklar (NPs) i olika tillämpningar i samhället har väckt oro när det gäller deras växelverkan med naturliga ekosystem. Syftet med denna studie är att ta fram data under förhållanden som simulerar realistiska scenarios och syftar till att förstå växelverkan mellan koboltbaserade NPs (Co, Co3O4 och Co SCS) och nickelbaserade NPs (Ni, NiO och Ni SCS) med naturliga nedbrytningsprodukter (biomolekyler, ekokorona) som utsöndras från Daphnia magna.

  4. 3. Investigating Particle Cracking in Single- and Polycrystalline Nickel-Rich Cathodes using In Situ Impedance Spectroscopy

    University essay from Uppsala universitet/Strukturkemi

    Author : Mattias Sjödin; [2021]
    Keywords : Electrochemical surface area; particle cracking; NMC811; transmission-line model; equivalent-circuit fitting; commercial Li-ion batteries;

    Abstract : State-of-the-art Li-ion cathode materials are based on LiMO2 (M=Ni, Mn, Co) layered transition metal oxides (denoted NMC) with Ni-rich composition because of their high specific capacity. Yet, these materials suffer from poor capacity retention due to crack formation during de-/lithiation cycling. READ MORE

  5. 4. Heavy metal removal and water treatment using Upsalite

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Philip Erenbo; [2017]
    Keywords : Upsalite; lead; cadmium; nickel; MgO3; heavy metal; water treatment;

    Abstract : Ion exchange reactions between Upsalite, a mesoporous magnesium carbonate, and metal ions of cadmium, lead and nickel have been studied to evaluate the capacities of Upsalite as a water treatment agent. Uptake capacity and reaction kinetics have been evaluated using a batch experiment and atomic absorption spectroscopy. READ MORE

  6. 5. µHDS system for desulfurization of logistic fuels for fuel cell applications

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Johan Karstensson; Nicklas Jönsson; [2016]
    Keywords : Jet fuel; DBT; thiophene; HDS; catalysis; kemiteknik; chemical engineering; Jet A1; Technology and Engineering;

    Abstract : Logistic fuels such as diesel and petrol, in which Jet A1 is included, are sulfur-containing fuels used for transports. The main problem with logistic fuels, when used in fuel cell (FC) applications, is their relatively high concentration of sulfur compounds. READ MORE
