  2. 11. Chemical Pollutants Released to the Marine Environment by Degradation of Plastic Debris

    Author : Berit Gewert; Matthew MacLeod; Magnus Breitholtz; Merle Plassmann; Martin Wagner; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plastic; microplastic; degradation; leachates; weathering; photo-oxidation; marine environment; toxicity; Applied Environmental Science; tillämpad miljövetenskap;

    Abstract : Since the beginning of the mass production in the 1940s, plastic has been manufactured in quickly increasing amounts. Plastic debris accumulates in the environment and lately much attention has been drawn to the pollution in the world’s oceans. READ MORE

  4. 12. High temperature corrosion of low-alloyed and stainless steels: mechanistic study of chlorine-induced corrosion

    Author : Mercedes Andrea Olivas Ogaz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steels; low-alloyed steels; pre-oxidation; High temperature corrosion; chlorine-induced corrosion;

    Abstract : The global demand on power generation is constantly increasing and so far, also its environmental impact. The environmental impact could primarily be directed to the power generation being based on fossil fuels, giving a net increase of CO2 to the atmosphere when combusted. READ MORE

  5. 13. High Temperature Corrosion of Stainless Steels - The Effects of Chloride Salts and SO2(g)

    Author : Sofia Karlsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : AbstractThe high corrosion rate of superheaters in waste- and biomass- fired plants is often linked to the presence of alkali chlorides. One way to mitigate the corrosion is to replace the superheater material with more corrosion- resistant materials. Another way is to change the corrosive environment by introducing fuel additives.

  6. 14. Isotopes as Mechanism Spies : Nucleophilic Bimolecular Substitution and Monoamine Oxidase B Catalysed Amine Oxidation Probed with Heavy Atom Kinetic Isotope Effects

    Author : Susanna MacMillar; Olle Matsson; Anita Hussénius; Daniel M. Quinn; Uppsala universitet; []
    Keywords : Organic chemistry; nucleophilic bimolecular substitution SN2; kinetic isotope effects; precision conductometry; monoamine oxidase B MAO B; reaction mechanism; carbon 11C 14C kinetic isotope effect; ion pairing triple-ion formation; para-substituted benzyl chlorides; tetrabytylammonium cyanide; Organisk kemi;

    Abstract : This thesis concerns the study of reaction mechanisms by means of kinetic isotope effects (KIEs). Studies of the nucleophilic bimolecular substitution (SN2) reaction had the dual purpose of improving our fundamental understanding of molecular reactivity and assessing the ability of kinetic isotope effects to serve as mechanistic tools.

  7. 15. Possibilities to use industrial oxidic by-products as neutralising agent in bioleaching and the effect of chloride on biooxidation

    Author : Chandra Sekhar Gahan; S. Subramanian; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : The cost for neutralisation is the second largest cost in a bioleaching operation for which, possibilities to replace generally used lime/limestone was tested. Industrial oxidic by-products generated form Swedish industries were investigated for neutralising capacities by chemical leaching with sulphuric acid at pH 1. READ MORE
