  2. 1. Atmospheric Corrosion of Lead. The Influence of Organic acid Vapours and Inorganic Air Pollutants. A contribution Towards Understanding the Environmental Degradation of Historic Organ Pipes

    Author : Annika Niklasson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; organ pipe; formic acid; Atmospheric corrosion; lead formate; lead acetate; NaCl; lead; acetic acid;

    Abstract : This thesis presents different perspectives on the atmospheric corrosion of lead, aiming at a better understanding of the environmental degradation of historical organ pipes. Corroded organ pipes from the field have been analyzed and the environment inside the organ wind system has been mapped. READ MORE

  4. 2. Atmospheric Corrosion of Historic Lead Organ Pipes

    Author : Annika Niklasson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atmospheric corrosion; conservation strategies; formiate; historical organs; organ pipe corrosion; lead; oak wood; formic acid; acetic acid; acetate;

    Abstract : The atmospheric corrosion of lead is investigated, with the aim to improve the understanding of the environmental degradation of historical organ pipes. Fieldwork is combined with laboratory investigations. The field studies included characterization of the organ environment and exposures of lead coupons. READ MORE

  5. 3. New Methods for the Synthesis of Vicinal Stereocenters : Palladium-Catalyzed Domino Reactions and Asymmetric Transfer Hydrogenation

    Author : Brinton Seashore-Ludlow; Somfai Peter; Kevin Booker-Milburn; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; asymmetric synthesis; domino reactions; palladium-catalyzed reactions; oxindoles; amino alcohols;

    Abstract : In this thesis the synthesis of vicinal stereocenters is investigated in two distinct contexts, namely the construction of 3,3-disubstituted oxindoles and the synthesis of b-hydroxy-a-amino acids. Both scaffolds are prevalent in a range of natural products and biologically relevant compounds and, therefore, methods for their synthesis are of great import. READ MORE

  6. 4. Structural enzymology of oxalate degradation in Oxalobacter formigenes

    Author : Catrine L Berthold; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Oxalic acid, as one of nature's most highly oxidised compounds, is toxic to most organisms. It is introduced in the human body in the diet but also as a waste product of cellular metabolism. Mammals do not posses the ability to degrade oxalate and must excrete it in the urine or through the intestine. READ MORE
