  1. 16. Anisotropic mechanical behaviors and microstructural evolution of thin-walled additively manufactured metals

    Author : Cheng-Han Yu; Johan Moverare; Ru Lin Peng; Joe Kelleher; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hot tensile testing; slow strain rate tensile testing; creep; anisotropy; crystallographic texture evolution; deformation twinning; Varmdragprov; Dragprov med låg töjningshastighet; kryp; anisotropi; kristallografisk textur; deformationstvillingar;

    Abstract : Additive manufacturing (AM), also known as 3D printing, is a concept and method of a manufacturing process that builds a three-dimensional object layer-by-layer. Opposite to the conventional subtractive manufacturing, it conquers various limitations on component design freedom and raises interest in various fields, including aerospace, automotive and medical applications.

  2. 17. Development of a Novel QCM Technique for Protein Adsorption Studies

    Author : Fredrik Höök; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; viscoelastic effects; myoglobin; QCM; hemoglobin; ferritin; dissipation factor; protein adsorption; conformational changes;

    Abstract : The first part of this thesis (Papers I and II) is concentrated on the development of a novel quartz crystal microbalance (QCM) technique to study protein adsorption. The second part (Papers III-V) is focused on the application of the technique on protein adsorption using well characterized surface-solution-protein systems. READ MORE

  3. 18. Clusterin and Megalin in The Spinal Cord

    Author : Grzegorz Wicher; Hakan Aldskogius; Lars Hillered; Anders Lewen; Robin Franklin; Uppsala universitet; []
    Keywords : Neurosciences; nerve degeneration; hypoglossal nerve; chaperone; apolipoprotein; development; transcription factor; astrocyte; glial differentiation; myelin; cell signalling; Neurovetenskap;

    Abstract : Nerve injury induces up-regulation of the chaperone protein clusterin in affected neurons and adjacent astrocytes but the functional significance of this response is unclear. We find that motor neuron survival is significantly greater in clusterin(+/+) compared to (-/-) mice. READ MORE

  4. 19. Deformation Behaviour, Microstructure and Texture Evolution of CP Ti Deformed at Elevated Temperatures

    Author : Zhipeng Zeng; Stefan Jonsson; Hans J. Roven; Bevis Hutchinson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Commercially pure titanium; Zener–Hollomon parameter; Dynamic recovery; Dynamic recrystallization; Recrystallized volume fraction; Grain size; Flow stress; Constitutive equation; Texture; High angle grain boundary; Low angle grain boundary; Deformation twinning; Schmid factor; Misorientation; Hot compression; Slip system; Subgrain; EBSD; Construction materials; Konstruktionsmaterial;

    Abstract : In the present work, deformation behavior, texture and microstructure evolution of commercially pure titanium (CP Ti) are investigated by electron backscattered diffraction (EBSD) after compression tests at elevated temperatures. By analysing work hardening rate vs. flow stress, the deformation behaviour can be divided into three groups, viz. READ MORE

  5. 20. Resilient and permanent deformation behavior of unbound aggregates under repeated loading

    Author : Fredrick Lekarp; KTH; []
    Keywords : ;

    Abstract : During recent decades, growing interest in the developmentof so-called analytical or mechanistic road pavement designmethods has resulted in substantial research into themechanical behavior of the materials involved. In flexiblepavements, especially when unsurfaced or thinly surfaced,overall structural performance is largely dependent on thebehavior of the unbound granular base and subbase layers. READ MORE
