    Abstract : This thesis is divided in four chapters, containing the work realised in two universities and has as the aim the synthesis of nitrogen-containing compounds. The first chapter describes the project realised at The University of Sheffield. READ MORE

  5. 3. Evolution of WC-Co cemented carbide microstructure during creep testing

    Author : Mohamed Amine Yousfi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plastic deformation; cemented carbides; linear intercept; transmission electron microscopy.; electron backscattered diffraction; Atom probe tomography;

    Abstract : The aim of this work is to understand the mechanisms behind the plastic deformation of WC-­Co based cemented carbides. The microstructures of two materials have been investigated before and after creep deformation using quantitative microscopy, atom probe tomography, and transmission electron microscopy. READ MORE

  6. 4. Microstructure Development of WC-Co Based Cemented Carbides During Creep Testing

    Author : Mohamed Amine Yousfi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plastic deformation; TEM; APT; EBSD; WC grain growth.; Cr segregation;

    Abstract : The aim of this work is to understand the mechanisms behind the plastic deformation of WC‐Co based cemented carbides. The microstructure of two series with different WC grain size was investigated before and after creep deformation using quantitative microscopy, atom probe tomography, and transmission electron microscopy.

  7. 5. Amine Transaminases in Biocatalytic Amine Synthesis

    Author : Henrik Land; Per Berglund; Helen C. Hailes; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amine Transaminase; Biocatalysis; Transamination; Reductive Amination; Enzyme; Enzyme Engineering; Equilibrium Displacement; Screening; Enzyme Stability; Bioteknologi; Biotechnology;

    Abstract : The use of enzymes, nature´s own catalysts, both isolated or as whole cells to perform chemical transformations is called biocatalysis. As a complement to classical chemical catalysis, biocatalysis can be an environmentally friendly and more economical option in the production and synthesis of chemicals. READ MORE
