  1. 1. Metal Affinity Peptides in Biotechnological Applications As tools in protein purification, protein stabilisation, metal quantification and metal tolerance of bacteria and plants

    Författare :Malin Mejàre; Tillämpad biokemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cadmium; metal quantification; fusion tag; metal affinity tag; phage display; peptide library; metal tolerance; metal resistance; metal accumulation; bioremediation; transgenic plant; tobacco; potato; protein purification; immobilised metal affinity chromatography; metal affinity precipitation; metal detection; protein stabilisation; Bioteknik; Biotechnology; Biokemi; Metabolism; Biochemistry; metal ion;

    Sammanfattning : Metal affinity tags have been fused to proteins and demonstrated to function as tools in protein purification, protein stabilisation, quantitative metal analysis and metal tolerance of bacteria and plants. In biotechnological applications proteins frequently have to function in nonnatural environments with harsh conditions which impose requirements for high stability on the proteins. LÄS MER

    Författare :Torbjörn Håkansson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; EDTA; metal; soil; remediation; Sulphate reducing bactera; biogas; water;

    Sammanfattning : Contamination of soil and water by heavy metal ions (HMs) is a problem all over the world.The use of biological methods alone or in combination with other techniques for treatment of such polluted sites constitutes a major challenge. LÄS MER

  4. 3. Protein-based capacitive biosensors for the detection of heavy-metal ions

    Författare :Alessia Mortari; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; heavy metal ions; protein; electrode; Biosensor; capacitance;

    Sammanfattning : Some metal ions, such as copper and zinc, are essential nutrients and catalysts in biochemical reactions. Other metal ions, e.g. cadmium and mercury, are highly toxic elements. LÄS MER

  5. 4. Structural Lithium Ion Battery Electrolytes

    Författare :Niklas Ihrner; Mats Johansson; Daniel Brandell; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Structural batteries; Structural battery electrolyte; Lithium ion batteries; Polymerization induced phase separation; Carbon fibers; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : A major challenge in the electrification of vehicles in the transport industry is that batteries are heavy, which reduces their effectiveness in mobile applications. A solution to this is structural batteries, which are batteries that can carry mechanical load while simultaneously storing energy. LÄS MER

  7. 5. Nanopolysaccharides for adsorption of heavy metal ions from water

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

    Sammanfattning : With population expansion and industrialization, heavy metal has become one of the biggest and most toxic water pollutants, which is a serious problem for human society today. The aim of this work is to explore the potential of nanopolysaccharides including nanocellulose and nanochitin to remove metal ions from contaminated water. LÄS MER
