  1. 16. Methodological advancements in microfluidic and carbonylation PET radiochemistry

    Författare :Kenneth Dahl; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Along with the progress of PET as a powerful imaging tool in medicine, there has been increasing demand for new labeling methods. The main aim of this PhD dissertation was to develop novel labeling methodologies using the positron emitter carbon-11. LÄS MER

  3. 17. 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. 18. Insights in Li-ion Battery Interfaces through Photoelectron Spectroscopy Depth Profiling

    Författare :Bertrand Philippe; Kristina Edström; Danielle Gonbeau; Hakan Rensmo; Rémi Dedryvère; Rosa Palacin; Maria Alfredsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lithium-ion batteries; negative electrodes; silicon; MnSn2; SEI; PES; XPS; synchrotron; Chemistry with specialization in Inorganic Chemistry; Kemi med inriktning mot oorganisk kemi;

    Sammanfattning : Compounds forming alloys with lithium, such as silicon or tin, are promising negative electrode materials for the next generation of Li-ion batteries due to their higher theoretical capacity compared to the current commercial electrode materials.An important issue is to better understand the phenomena occurring at the electrode/electrolyte interfaces of these new materials.

  5. 19. Vibrational Sum Frequency and Infrared Reflection/Absorption Spectroscopy Studies of the Air/Liquid and Liquid/Metal Interfaces

    Författare :Magnus Johnson; Christofer Leygraf; Andrew Gewirth; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Corrosion science; laser spectroscopy; nonlinear optics; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Atmospheric corrosion, the most common form of metal corrosion, occurs within the interfacial region between a solid, and the surrounding atmosphere. In fact three phases and two interfaces are involved: the gas, a thin liquid layer, a solid, the gas/liquid and the liquid/solid interfaces. LÄS MER

  7. 20. Resin composites : Sandwich restorations and curing techniques

    Författare :Anders Lindberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Adaption; Clinical; Degree of conversion; Depth of cure; Flowable; Resin composite; Restorations; SEM; Medicin;

    Sammanfattning : Since the mid-1990s resin composite has been used for Class II restorations in stress-bearing areas as an alternative to amalgam. Reasons for this were the patients’ fear of mercury in dental amalgam and a growing demand for aesthetic restorations. LÄS MER
