  1. 6. A Surface Phase Model of the Alveolar Lining: Ultrastructural Analysis and in vivo Applications

    Författare :Marcus Larsson; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; X-ray diffraction; cryo-TEM; dynamic swelling; ARDS; surface phase; surfactant replacement therapy; cholesterol; minimal surface; pulmonary surfactant; alveolar surface; Physiology; Fysiologi;

    Sammanfattning : In this thesis the relation between lung surfactant structure and functional properties have been studied. Experimental results show that the alveolar surface is formed by a coherent surface phase with a structure equal to tubular myelin. The properties of this phase may explain certain unresolved issues in lung physiology, e.g. LÄS MER

  3. 7. Molecular Thermodynamic Models for Nano-Micro Fluid/Solid Interfaces

    Författare :Nanhua Wu; Xiaoyan Ji; Yuanhui Ji; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Introducing materials with large interfaces to enhance process performance has become a feature of advanced chemical engineering, where the research focus has been changed from the traditional ideal isotropic fluid in the bulk phase to the highly non-ideal anisotropic confined fluid on the nano-micro interfaces, owing to the strong and asymmetric interactions between the complex fluids (supported metal nanoparticles, ionic liquids, proteins, etc.) and the sophisticated solid-surface (roughness, electrostatic effects, chemical heterogeneities, etc. LÄS MER

  4. 8. Deep generated methane in the global methane budget

    Författare :Elena Mukhina; Vladimir G. Kutcherov; Natalia Dubrovinskaya; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Energy Technology; Energiteknik;

    Sammanfattning : Methane is a significant part of the global carbon cycle. The distribution of methane above and below the Earth’s surface suggests that atmospheric methane might be related to methane originating from the deep mantle. LÄS MER

  5. 9. Modeling ionic liquids with ePC-SAFT ─ properties and gas solubilities

    Författare :Yunhao Sun; Xiaoyan Ji; Xiaodong Liang; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

    Sammanfattning : Global warming is now widely recognized as being the biggest global issue facing human beings. Mitigating CO2 emission from fossil-fueled power plants as well as from transports has become an urgent and worldwide research topic, in which CO2 separation is often needed. LÄS MER

  7. 10. Application of Rare-Earth Doped Ceria and Natural Minerals for Solid Oxide Fuel Cells

    Författare :Yanyan Liu; Andrew R. Martin; Wujun Wang; Shanwen Tao; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-temperature solid oxide fuel cells; Doped ceria; Material characterizations; Electrochemical performances; Natural minerals; Lågtemperatur fastoxidbränsleceller; Dopade ceriumoxid; Materialkarakteriseringar; Elektrokemiska prestanda; Naturliga mineraler.; Energy Technology; Energiteknik; Teknisk materialvetenskap; Materials Science and Engineering; Chemical Engineering; Kemiteknik;

    Sammanfattning : Although solid oxide fuel cell (SOFC) technology exhibits considerable advantages as compared to other energy conversion devices, e.g. high efficiency, low emission and fuel flexibility, its high operating temperature leads to rapid component degradation and has thus hampered commercialization.
