  4. 13. Analysis of Acrylamide and Anthocyanins in Foods : Extraction Optimization for Challenging Analytes

    Författare :Erik V. Petersson; Charlotta Turner; Johan Rosén; Rolf Danielsson; Marja-Liisa Riekkola; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Analysis; Extraction; Optimization; Acrylamide; Anthocyanins; Foods; Challenges; Analytical chemistry; Analytisk kemi; Analytical Chemistry; Analytisk kemi;

    Sammanfattning : In this thesis, the main concern has been to improve the reliability of different parts of the analytical workflow (Paper I, II, IV &V). Additionally, one of the resulting optimized methods was used in a real application (Paper III). Paper I-II concerned the extraction of acrylamide (AA) from foods. LÄS MER

  5. 14. Delubrication of Chromium Prealloyed Powder Metallurgy Steels

    Författare :Seshendra Karamchedu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alloyed sintered steels; delubrication; surface oxide; sintering atmosphere; processing atmosphere control; lubricant;

    Sammanfattning : Consolidation of steel components produced by means of powder metallurgy (PM) is achieved typically through compaction and sintering. During consolidation, final dimensions of the part are already achieved after compaction, while sintering imparts strength to the components. LÄS MER
