  2. 16. Lipidic-sponge phase crystallisation and time-resolved Laue diffraction studies of bacterial photosynthetic reaction centres

    Author : Annemarie Wöhri; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; lipidic-sponge phase crystallization reaction centre from Rhodobacter sphaeroides and Blastochloris viridis photosynthesis evolution time-resolved Laue diffraction;

    Abstract : Photosynthesis is the procedure of light capture and converting it into a chemical energy source for the cell. The work-horse of this process are photosynthetic reaction centres, which capture photons with the help of their antenna complexes and use these photons to drive charge separation reactions, and ultimately chemiosmotic coupling.

  4. 17. Spatial and temporal aspects of intense attosecond pulses for pump-probe experiments

    Author : Hampus Wikmark; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultrafast lasers; ultrafast optics; attosecond pulses; pump-probe experiments; XUV light; XUV focusing; wavefront sensing; XUV optics; X-ray optics; Fysicumarkivet A:2019:Wikmark; ultrasnabba lasrar; attosekundspulser; pump-prob-experiment; XUV-ljus; vågfrontmätningar; XUV-optik; Röntgen-optik;

    Abstract : Nuclear and electronic dynamics in atoms and molecules are the foundation of many physical processes and chemical reactions. Often, these dynamics take place on timescales so much shorter than those commonly encountered that they are called ultrafast. READ MORE

  5. 18. Micro-Crystallization and Time-Resolved Diffraction Studies of a Bacterial Photosynthetic Reaction Center

    Author : Petra Båth; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Photosynthesis is one of the most important set of chemical reactions in nature as they can convert sunlight into hydrocarbons and chemical energy. The proteins responsible for this are two general types of reaction centers that can be found in a wide variety of living organisms capable of photosynthesis, from bacteria to algae and plants.

  6. 19. On the Challenges for Time-of-Flight Electron Spectroscopy at Storage Rings

    Author : Christian Stråhlman; Lunds universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; time-of-flight; photoelectron spectroscopy; MAX IV; storage ring; detector gating; chopper; coincidence spectroscopy;

    Abstract : Time-of-flight (TOF) techniques for energy analysis have been common in electron spectroscopy for many decades. TOF-based electron spectrometers benefit from higher transmission and information rate compared to their main competitor: the hemispherical analyser; the drawback being their lower energy resolution.

  7. 20. Time dependent pressure phenomena in hydropower applications

    Author : Magnus Lövgren; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

    Abstract : Time resolved pressure measurements in hydropower applications are of great interest. Different parts of the machine experience highly transient flows that influence the function and efficiency of the turbine. This thesis addresses different time dependent pressure phenomena. READ MORE
