  1. 1. Wide-angle scanning wide-band phased array antennas

    Författare :Anders Ellgardt; Martin Norgren; Lars Josefsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning : This thesis considers problems related to the design and the analysis of wide-angle scanning phased arrays. The goals of the thesis are the design and analysis of antenna elements suitable for wide-angle scanning array antennas, and the study of scan blindness effects and edge effects for this type of antennas.

  3. 2. Conformational Dynamics of Rhodopsins Visualized by Time-resolved Wide Angle X-ray Scattering

    Författare :Erik Malmerberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Time-resolved wide Angle X-ray Scattering; Retinylidene proteins; Rhodopsin; Bacteriorhodopsin; Proteorhodopsin;

    Sammanfattning : Rhodopsins are a family of light-sensitive proteins found in the cellular membranes of a wide range of living organisms. These membrane proteins share a common molecular architecture and are able to use light energy to perform a variety of different biological functions. 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.

  7. 5. X-ray free-electron laser based methods for structural and ultrafast dynamics studies of a photosynthetic reaction centre

    Författare :David Arnlund; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; WAXS; wide-angle x-ray scattering; XFEL; x-ray free-electron laser; reaction center; structural biology; ultrafast dynamics;

    Sammanfattning : Life on earth is fuelled by the energy of sunlight, which must first be captured and converted into a chemical energy form useful to the cell. This process is known as photosynthesis and the major pathway of this energy conversion is via photosynthetic reaction centres. LÄS MER
