  1. 16. Environmental Applications of Aquatic Remote Sensing

    Författare :Petra Philipson née Ammenberg; Eugenio Zilioli; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; Bildanalys; Image analysis; Bildanalys; Computerized Image Analysis; datoriserad bildanalys;

    Sammanfattning : Many lakes, coastal zones and oceans are directly or indirectly influenced by human activities. Through the outlet of a vast amount of substances in the air and water, we are changing the natural conditions on local and global levels. LÄS MER

  3. 17. Production of polyhydroxyalkanoates in biological treatment of industrial wastewaters

    Författare :Simon Bengtsson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyhydroxyalkanoates; mixed cultures; glycogen accumulating organisms GAO ; feast and famine; acidogenic fermentation; activated sludge;

    Sammanfattning : In search of more environmentally friendly polymer materials, polyhydroxyalkanoates (PHAs) have been considered as promising candidates. PHAs exhibit a broad range of material properties, can be produced from renewable resources and are completely biodegradable. LÄS MER

  4. 18. The aquatic ecotoxicity of manufactured silica nanomaterials and their interactions with organic pollutants

    Författare :Frida Book; Göteborgs universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Manufactured silica nanomaterials are one of the nanomaterials consumed in the highest volumes (more than 4 000 000 tons/year/globally) and are used in a wide range of products and industries such as food, cosmetics, coatings, paints, textiles, concrete and the paper and pulp industry. They also provide promising properties that help solving societal challenges, such as water remediation, by binding contaminants. LÄS MER

  5. 19. Modified and hybrid cellulose-based materials for water purification

    Författare :Dimitrios Georgouvelas; Aji Mathew; Henrikki Liimatainen; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Cellulose; lignocellulose; membranes; water treatment; heavy metal adsorption; dye adsorption; scalability; materialkemi; Materials Chemistry;

    Sammanfattning : The need for clean water has led to the development of several different water treatment methods as well as to a large number of organic, inorganic, hybrid and/or composite materials that are used in these methods. Cellulose, being a highly abundant biopolymer with meritorious properties, such as high mechanical strength, tunable surface chemistry, high aspect ratio and surface area, to mention a few, is exploited in the current thesis for water treatment applications.
