  1. 1. Microstructure and oxidation behavior of High Velocity Oxy-Fuel spray deposited Ti2AlC coatings

    Författare :Marie Sonestedt; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coatings; High Velocity Oxy-Fuel HVOF ; Ti2AlC; oxidation; microstructure; SEM; TEM;

    Sammanfattning : Ti2AlC is one of the ternary carbides in the MAX phase group of materials. This group of materials have a unique combination of ceramic and metallic properties, such as machinability, high thermal conductivity, low density and oxidation resistance. LÄS MER

  3. 2. Performance of MCrAlX coatings : Oxidation, Hot corrosion and Interdiffusion

    Författare :Pimin Zhang; Ru Lin Peng; Xin-Hai Li; Sten Johansson; Ping Xiao; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : MCrAlY coatings (M=Ni and/or Co) are widely used for the protection of superalloy components against oxidation and hot corrosion in the hot sections of gas turbines. The drive for coating systems to bestow adequate oxidation and corrosion resistance upon the components becomes urgent as an inevitable result of the necessary improvement in engine combustion efficiency and service lifetime.

  4. 3. Oxidation behaviour of MCrAlX coatings : effect of surface treatment and an Al-activity based life criterion

    Författare :Pimin Zhang; Ru Lin Peng; Xin-Hai Li; Sten Johansson; Fang Liu; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : MCrAlY coatings (M=Ni and/or Co) have been widely used for the protection of superalloy components against oxidation and hot corrosion in the hot sections of gas turbines. The drive to improve engine combustion efficiency while reducing emissions by increasing the operation temperature brings a big challenge for coating design. LÄS MER

  5. 4. Protein stabilization. Some methods and mechanisms

    Författare :Maria Andersson; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sorbitol; protein stability; preferential exclusion; polyol; poly-NIPAAm; polymer; poly ethyleneimine ; polyelectrolyte; oxidation; NMR spectroscopy; lysozyme; lactate dehydrogenase; fluorescence; dynamic light scattering; complex; additive; circular dichroism; stabilization; trypsin; thermo-reversible polymer.; Biotechnology; Bioteknik;

    Sammanfattning : The effect of different additives on protein stability was studied, and the basis for stabilization was investigated at molecular level. The addition of sorbitol enhanced thermal stability of hen egg white lysozyme in aqueous solution. LÄS MER

  7. 5. Experimental therapeutics against malignant mesothelioma : investigations in vitro

    Författare :Gustav Nilsonne; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Malignant mesothelioma is a tumour of the mesothelium, a specialized tissue found in the pleura, pericardium, peritoneum, and tunica vaginalis testis. The tumour has strong etiological links to asbestos, with a latency period ranging up to several decades between asbestos exposure and tumour diagnosis. LÄS MER
