  1. 1. Using Molecular Dynamics Simulations to Explore Critical Property Relationships in Polymer Electrolytes : Polarity, Coordination, Ionic transport, Ion-pairing, and Ion-ion Correlations

    Författare :Harish Gudla; Daniel Brandell; Chao Zhang; Andreas Heuer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Solid polymer electrolytes; molecular dynamics simulations; solvent polarity; ion-pairing; ion coordination; ion transport mechanisms; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Sammanfattning : While ion transport in solid polymer electrolytes (SPEs) has been explored for decades, there still remains controversies about its fundamental properties, often correlated with gaps between experimental and computational studies. Using molecular dynamics simulations to understand the complex transport mechanisms and also to fill these gaps is the main goal of this thesis. LÄS MER

  3. 2. Modelling the microstructural changes in steels due to fusion welding

    Författare :John Ion; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materialteknik; Engineering Materials;

    Sammanfattning : Theoretical, physically-based models of fusion welding are developed, and calibrated using experimental data from practical welds. The following heat-affected zone phenomena are investigated: grain growth, precipitate dissolution and coarsening, martensite formation and hardness. LÄS MER

  4. 3. Regenerative medicine of the airway cartilage : a morphological and immunohistochemical study with focus on cricoid cartilage defects treated with BMP-2

    Författare :Ion Tcacencu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Larynx; growth factor; wound healing; perichondrium; progenitor cells; osteogenesis; growth plate.;

    Sammanfattning : Background: Cartilage provides flexible support for upper airway. Induction of cartilage healing is required for the success of many surgical interventions in the head and neck that are used as treatments for several diseases, such as subglottic stenosis and tumors of the larynx and thyroid.
