    Sammanfattning : Climate change is a growing threat to mankind. The message from the scientific community is clear: we need to act fast and profoundly. The political response has, however, been slow. The likelihood that we will be able to meet our political climate goals only by reducing emissions is slim. LÄS MER

  3. 2. Pulmonary imaging with quantification of T1-relaxation and oxygen enhanced MRI

    Sammanfattning : Bildtagning med magnetresonans (mangetic resonance imaging eller MRI) är en fascinerande teknik som använder magnetfält och radiovågor för att skapa detaljerade bilder av kroppens innanmäte. Tvärt om mot vad många tror så finns det ingen ”magnetröntgen” i MR-kameran, och därmed ingen skadlig joniserande strålning. LÄS MER

  4. 3. X-Ray Diagnostics in Combustion - Study of Particle Formation in Flames Using Combined Small- and Wide-Angle X-Ray Scattering

    Författare :Linda Vallenhag; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nanoparticles; soot particles; WAXS; X-ray scattering; SAXS; combustion; Fysicumarkivet A:2014:Vallenhag;

    Sammanfattning : In the thesis work, two X-ray scattering techniques, small- and wide-angle X-ray scattering (SAXS and WAXS) were combined to study particle formation in-situ and non-intrusively in ethylene laboratory flames. Combining these two techniques enabled information concerning the size and concentration as well as the subnanometer structure of the nanoparticles within the 1–100 nm range there to be obtained.
