  5. 8. Alkali Induced Corrosion of 304L, The Influence of Potassium Salts and Water Vapour

    Author : Jesper Pettersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 304L; Alkali; Breakaway Corrosion; KCl; Oxidation; Deposit;

    Abstract : This work investigates the influence of alkali salts on the oxidation of304-type (Fe18Cr10Ni) austenitic stainless steel in laboratory and fieldexposures. Stainless steel coupons were exposed isothermally inlaboratory furnaces at 400-600 °C in 5% O2 and 5% O2 + 40% H2O.Thermobalance exposures were also performed. READ MORE

  6. 9. Modeling and Optimization of Reversed-Phase Chromatography : Effects of Modulators and Temperature

    Author : Karolina Arkell; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reversed-phase chromatography; Hydrophobic interaction chromatography; Mechanistic modeling; INSULIN; KCl; Ethanol; Temperature; Multi-objective optimization; Constraint; Solubility;

    Abstract : Many widespread diseases, such as diabetes, various types of cancer, and aggressive versions of influenza, are treated or prevented with biopharmaceuticals. Biopharmaceuticals are drugs that are based on proteins, peptides, antibodies, attenuated viruses (vaccines), and other biomolecules that are synthesized predominately in bacteria, yeast, and mammalian cells.

  7. 10. Microscopy of high temperature oxidation of iron and some stainless steels

    Author : Torbjörn Jonsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; water vapour; sulphur dioxide; FIB; X20; stainless steel; 353MA; EDX; KCl; FIB SEM; SEM; microstructure; TEM; iron; High-temperature oxidation; in-situ ESEM;

    Abstract : This thesis concerns the high temperature oxidation of iron and some stainless steels. The oxide scales, as well as the subjacent metal, were investigated using a range of electron and ion microscopy techniques, including SEM, TEM, EDX and FIB. The aim was to link the microstructural observations to the oxidation mechanisms of the materials. READ MORE
