  1. 26. Water and Protein Dynamics in Biological Systems Studied by Magnetic Relaxation Dispersion

    Författare :Erik Persson Sunde; Biofysikalisk kemi; []
    Nyckelord :protein dynamics; ubiquitin; BPTI; Escherichia coli; Haloarcula marismortui; nuclear magnetic resonance; protein hydration; magnetic relaxation dispersion; water dynamics; cell water;

    Sammanfattning : The results presented in this thesis demonstrate that the magnetic relaxation dispersion (MRD) technique can provide information of relevance to protein biophysics, magnetic resonance imaging and cell biology. By immobilizing proteins with covalent cross-links, intermittent protein dynamics on the previously inaccessible ns-µs time scale could be probed with MRD via the exchange of water molecules between internal cavities and the surrounding bulk solvent phase.

  2. 27. Growth of thick GaN layers on sapphire by Hydride Vapour Phase Epitaxy

    Författare :Henrik Larsson; Werner Seifert; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Gallium nitride (GaN) is a wide bandgap material that is already extensively used in industrial production of optoelectronic devices (light emitters) that operate in the blue and ultraviolet wavelength range. GaN is interesting not only because it has a wide bandgap (3. LÄS MER

  3. 28. FEM Modelling of Micro-galvanic Corrosion in Al Alloys Induced by Intermetallic Particles : Exploration of Chemical and Geometrical Effects

    Författare :Litao Yin; Jinshan Pan; Christopher Leygraf; Ying Jin; Herman Terryn; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Finite Element Method FEM ; Modelling; Micro-galvanic corrosion; Al alloy; corrosion product deposition; chemical factors; steric hindrance effect; Kemi; Chemistry;

    Sammanfattning : Localized corrosion, such as pitting, crevice corrosion or galvanic corrosion, is a long-standing phenomenon that can greatly limit the life of metallic materials. For decades experimental methods have been used to try to understand the underlying physical, chemical and electrochemical processes that control localized corrosion in order to find effective protection methods against its propagation.

  4. 29. Study of novel electronic materials by mid-infrared and terahertz optical Hall effect

    Författare :Nerijus Armakavicius; Vanya Darakchieva; Philipp Kühne; Mircea Modreanu; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Development of silicon based electronics have revolutionized our every day life during the last three decades. Nowadays Si based devices operate close to their theoretical limits that is becoming a bottleneck for further progress. LÄS MER

  5. 30. Historical patterns of globalization : the growth of outward linkages of Swedish long-standing transnational corporations, 1890s-1990s

    Författare :Richard Palmer; Lennart Schön; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; foreign employment; foreign sales; foreign subsidiaries; globalization; history; Sweden; Swedish economy; transnational corporations TNCs .; Economic History; ekonomisk historia;

    Sammanfattning : The study addresses the outward cross-border linking of the Swedish economy and its most important transnational corporations during the 20th century. It explores the aggregate level of Swedish industry, and most importantly, the firm level of a group of eight long-standing transnational corporations, which during the post-1945 period represented roughly half of Sweden’s foreign industrial activity in terms of employment, e.
