  1. 1. Algorithms for Coherent Diffractive Imaging with X-ray Lasers

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Benedikt J. Daurer; Uppsala universitet.; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray lasers; coherent diffractive imaging; algorithms; lensless imaging; flash diffractive imaging; flash X-ray imaging; aerosol injection; FEL; XFEL; CXI; CDI; FXI; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Coherent diffractive imaging (CDI) has become a very popular technique over the past two decades. CDI is a "lensless" imaging method which replaces the objective lens of a conventional microscope by a computational image reconstruction procedure. READ MORE

  2. 2. Imaging Living Cells with an X-ray Laser

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Gijs van der Schot; Uppsala universitet.; [2018]

    Abstract : Imaging living cells at a resolution higher than the resolution of optical microscopy is a significant challenge. Fluorescence microscopy can achieve a degree of super-resolution via labeling cellular components with a fluorescent dye. READ MORE

  3. 3. Femtosecond Dynamics in Water and Biological Materials with an X-Ray Laser

    University dissertation from Uppsala universitet

    Author : H. Olof Jönsson; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Using high intensity ultrashort pulses from X-ray free electron lasers to investigate soft matter is a recent and successful development. The last decade has seen the development of new variant of protein crystallography with femtosecond dynamics, and single particle imaging with atomic resolution is on the horizon. READ MORE

  4. 4. Ultrafast Structural and Electron Dynamics in Soft Matter Exposed to Intense X-ray Pulses

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

  5. 5. Protein Folding and DNA Origami

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Mark Marvin Seibert; Uppsala universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; protein folding; Molecular Dynamics simulations; DNA origami; TECHNOLOGY Engineering physics Biophysics; TEKNIKVETENSKAP Teknisk fysik Biofysik; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : In this thesis, the folding process of the de novo designed polypeptide chignolin was elucidated through atomic-scale Molecular Dynamics (MD) computer simulations. In a series of long timescale and replica exchange MD simulations, chignolin’s folding and unfolding was observed numerous times and the native state was identified from the computed Gibbs free-energy landscape.
