  1. 1. Alkylglucosides - physical chemical properties

    Författare :Frederik Nilsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; penetration experiment; DSC; SAXS; NMR self-diffusion; phase separation; size micro-structure; aggregate-aggregate interaction; liquid crystalline phases; micelles; alkylglucosides; phase diagrams; fluorescence.; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. LÄS MER

  3. 2. Characterization of Micro-Structures in Materials

    Författare :Henrike Häbel; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Clustering; colloidal nanoparticle gels; image analysis; mass transport; point pattern; polymer blended films; pore shape; polymer blended films;

    Sammanfattning : On developing the next generation sustainable soft materials, it is often crucial to understand and control their properties and function. Whereas a characterization of three-dimensional data is desirable in corresponding studies, often two-dimensional data are less time consuming to obtain. LÄS MER

  4. 3. Creep Behaviour of Titanium Aluminides and its Relation to Phase Distributions and Dislocation Structures

    Författare :Dennis Lundström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gamma-TiAl; twinning; fatigue; dislocations; microstructure; thermal transport properties; creep;

    Sammanfattning : The need for more efficient gas turbines with lowered fuel consumption and thereby lowered emission has recently lead to increased interest in low-density, .gamma.-based TiAl intermetallic alloys as a replacement of e.g. LÄS MER

  5. 4. From experiments with images to 3D models

    Författare :Henrike Häbel; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colloidal particle aggregation; Anisotropy; mass transport; image analysis; Gibbs point processes; porous polymer blended films; porous polymer blended films;

    Sammanfattning : For developing the next generation sustainable materials, it is often crucial to understand and control their properties and function. This work presents cross-disciplinary research starting with experimentally fabricated porous soft biomaterials and images of their micro-structure obtained by electron or laser microscopy. LÄS MER

  7. 5. Computational Homogenization of Transient Problems - Application to Porous Media

    Författare :Fang Su; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; consolidation; Representative Volume Element RVE ; homogenization; FE2;

    Sammanfattning : This thesis is devoted to the development and analysis of a homogenization-basedcomputational strategy for simulating the transient and nonlinear coupled consolidationproblem in micro-heterogeneous porous media. A variational framework and the pertinentfinite element (FE) strategy, based on a generalized macro-homogeneity condition,are proposed for the spatial homogenization of a class of transient problems, wherebythe classical assumption of first order homogenization is adopted.
