  1. 1. Sand och fyra reaktiva filters avskiljningsförmåga av metaller frånvägdagvatten : Fältstudie under vintertid

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

    Författare :Anders Melander; [2023]
    Nyckelord :Stormwater treatment; Metal removal; Reactive filters; Sand filter; Road runoff; Dissolved metals; Total metals; Dagvattenbehandling; Metallavskiljning; Reaktiva filter; Sandfilter; Vägavrinning; Lösta metaller; Totala metaller;

    Sammanfattning : Dagvatten från urbana områden utgör en ökande utmaning för växande städer, eftersom det för med sig metallpartiklar och andra föroreningar från hårdgjorda ytor till närliggande vattenförekomster. Dessa föroreningar kan härstamma från källor som fordonstrafik och korrosion av metallstrukturer. LÄS MER

  3. 2. Michael additions utilizing transition-metal-catalysts, Scope and limitations

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Ruben Hansson; [2023]
    Nyckelord :Green chemistry; transition metal; rare earth metal; Michael addition; Yb; Zr; Hf; analytical chemistry; Chemistry;

    Sammanfattning : The effect that organic solvents have on the environment and the intrinsic risk that come with using them should be limited. By replacing organic solvents with less harmful solvents, such as water, and with more effective catalysts can risks intrinsic to organic solvents be minimized or eliminated. LÄS MER

  4. 3. Uptake and retainment of radionuclides in edible mushrooms – from fruiting to cooking

    Master-uppsats,

    Författare :Delshad Mansour Ayoubi; [2022-12-06]
    Nyckelord :Medical physics; Activity concentration; Transfer coefficient; Dose;

    Sammanfattning : Purpose: The purpose of this study was to study the uptake, distribution and transfer of Mn-54, Zn-65, U-238, U-235, U-234, and Po-210 in mushrooms and their respective caps and stalks, the effects of chelates and ligands, and the potential release of radionuclides during a cooking procedure. Introduction: Fungi are organisms that are composed of a fruiting body (mushroom) and tubular hyphae, that branches out into complex networks called mycelium. LÄS MER

  5. 4. Green Protein Hydrogels and Non-dry Aerogels in Water Purification

    Kandidat-uppsats, KTH/Kemi

    Författare :Emanuel Nelsson Vedung; Alexander Singh; Julia Wadefjord; [2022]
    Nyckelord :Aerogel; Hydrogel; Whey Protein Isolate; Water purification; Adsorption; Sustainability;

    Sammanfattning : Having access to clean water is not a certainty for every human being. Today, there are major problems with polluted water that not just affect us humans, but also the ecosystem around us. In recent years, research into making aerogels from protein nanofibrils (PNF) has increased. LÄS MER

  7. 5. Electrochemical Behavior of the High Entropy Oxide (Mg,Co,Ni,Zn)1-xLixO (x=0,35)

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Rasmus Sandström Kinnane; [2022]
    Nyckelord :high entropy oxides; lithium-ion battery; x-ray diffraction; scanning electron microscopy; cyclic voltammetry;

    Sammanfattning : Today's society is currently developing lithium-ion batteries to eventually replace the use of fossil fuels. High entropy oxides is a new type of material to use as an anode in the lithium-ion battery. These high entropy oxides may consist of a few different transition metals including lithium and oxygen.
