  1. 1. Corrosion Behavior of HVAF-Sprayed Bi-Layer Coatings

    Författare :Esmaeil Sadeghimeresht; Nicolaie Markocsan; Per Nylén; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal spray coating; HVAF; Corrosion protection; Galvanic corrosion; Composition; Microstructure; EIS; Polarization; OCP; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : In a variety of engineering applications, components are subjected to corrosive environment. Protective coatings are essential to improve the functional performances and/or extend the lifetime of the components. LÄS MER

  3. 2. Nanostructured Ceramics - Synthesis and Understanding

    Författare :Farnaz Ghajeri; Wei Xia; Freddy Kleitz; Uppsala universitet; []
    Nyckelord :Material Science; Nanoporouse Silica; Calcium Phosphate; Synthesis; Characterization; Adsorption; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : During the last years, nanostructured ceramics have been favored for use in the industry due to their beneficial properties. For example, calcium phosphate ceramics with their biocompatible and bioactive characteristics are beneficial in biomedicine. LÄS MER

  4. 3. Inorganic chemistry of phosphorus cycling in fresh and marine waters

    Författare :Anneli Gunnars; René Gätcher; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; strukturkemi; Structural Chemistry;

    Sammanfattning : In the present Thesis, new results are reported on critical chemical mechanisms controlling the cycling of phosphorus in aquatic environments. These findings have implications for several fields of earth system sciences, including large-scale global change, both Recent and in older geological periods. LÄS MER

  5. 4. Advanced Functional Materials for Intermediate-Temperature Ceramic Fuel Cells

    Författare :Zhan Gao; Bill Bergman; Mogens Mogensen; Ceramics; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Low to intermediate-temperature solid oxide fuel cell (SOFC, 500 oC-700 oC) based on doped ceria (DCO) electrolyte has attracted much attention during the last decade. However, DCO suffers from electronic conduction caused byreduction of Ce (IV) to Ce (III) at high temperatures and low oxygen partial pressures and has a high grain-boundary resistivity. LÄS MER

  7. 5. Determination of the overall haemostasis potential and fibrin gel permeability : method development and application in research and in clinical materials

    Författare :Aleksandra Antovic; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Global haemostatic assays; overall haemostasis potential; hypercoagulation; hypocoagulation; thrombophilia; haemophilia; fibrin gel porosity; LMMH therapy; acetylsalicylic acid therapy;

    Sammanfattning : We have previously developed a laboratory method that may screen the Overall Haemostasis Potential (OHP) in plasma based on spectophotometric measurement of an area under the fibrin aggregation curve in citrated plasma samples to which tiny amounts of exogenous thrombin and tissue-plasminogen activator (t-PA) are added. When the fibrin aggregation curve is created, the fibrinogen originally present in plasma is gradually converted to fibrin by the generated thrombin. LÄS MER
