  1. 31. Adsorption behavior of heavy metal ions from aqueous medium on nanocellulose

    Författare :Peng Liu; Lars Wågberg; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : The aim of this work was to explore the potential of nanocellulose, nanocellulose derivatives and nanochitin to remove metal ions from contaminated water. The above nano-polysaccharides were of interest in water purification technologies due to their high surface area and versatile surface chemistry. LÄS MER

  3. 32. Heavy metal tolerance, uptake, accumulation, and translocation in Salix and its application in phytoremediation

    Författare :Tommy Landberg; Maria Greger; Nicholas Dickinson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plant stress heavy metals Salix tolerance; växtfysiologi; Plant Physiology;

    Sammanfattning : In the environment, heavy metals are major stressors for plants, and since plants are immobile, they cannot avoid the stress but must adapt. Therefore, plants may develop avoidance and tolerance mechanisms to reduce susceptibility to metal toxicity. LÄS MER

  5. 34. Heavy metal-induced activation of the murine immune system and autoimmunity : a comparative study of mercury and silver

    Författare :Uno Johansson; Klas Nordlind; Östergötlands Läns Landsting; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The activation and proliferation ofT- and B-cells induced by treatment with mercuric chloride (HgC12) or silver·nitrate (AgN03) was studied in mouse strains genetically susceptible (SJL, A. SW, A.TH, BALE/C) or resistant (A.TL, BALB. LÄS MER

  7. 35. Investigation of compositionally complex refractory metal based thin films

    Författare :Barbara Osinger; Erik Lewin; Ulf Jansson; Sebastian Siol; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetron sputtering; Thin films; High entropy materials; Refractory metals; Transition metal carbides; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : The search for new and improved materials has led to the discovery and establishment of compositionally complex or high-entropy materials. The work in this thesis is focused on the investigation of new compositionally complex materials based on the refractory metals of groups 4-6. LÄS MER
