  1. 6. Mesoporous Building Blocks : Synthesis and Characterization of Mesoporous Silica Particles and Films

    Författare :Emma M. Björk; Magnus Odén; Fredik Söderlind; José Córdoba; Mika Lindén; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Catalyst supports, drug delivery systems, hosts for nanoparticles, and solar cells are just some examples of the wide range of exciting applications for mesoporous silica. In order to optimize the performance of a specific application, controlling the material’s morphology and pore size is crucial. LÄS MER

  3. 7. Retrogradation Properties of Starch

    Författare :José Silverio; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; surfactants; lipids; degree of polymerization DP ; isothermal microcalorimetry; differential scanning calorimetry DSC ; crystallinity; amylose; amylopectin; gelatinization; starch; retrogradation; temperature cycling; PCA; Food and drink technology; Livsmedelsteknik;

    Sammanfattning : The main purpose of this thesis was to examine various factors influencing starch retrogradation. The reassociation events of starch, which are closely linked to the staling of bakery products, were mainly studied by thermal analysis. Some aspects of starch gelatinization are also included.

  4. 8. Controlling Polylactide Degradation through Stereocomplexation and Lactic Acid Based Additives

    Författare :Sofia Regnell Andersson; Minna Hakkarainen; Ann-Christine Albertsson; Marek Kowalczuk; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polylactide; stereocomplex; plasticizer; degradation; degradation products; ESI-MS;

    Sammanfattning : The successful use of degradable materials in new applications depends on our ability to control the degradation process. A number of aspects need to be evaluated including degradation rate, the onset of degradation and the nature, formation and release of degradation products. LÄS MER

  5. 9. Atom Probe Tomography of TiSiN Thin Films

    Författare :David Engberg; Lars Hultman; Magnus Odén; Fang Liu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis concerns the wear resistant coating TiSiN and the development of the analysis technique atom probe tomography (APT) applied to this materials system. The technique delivers compositional information through time-of-flight mass spectrometry, with sub-nanometer precision in 3D for a small volume of the sample. LÄS MER
