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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Max Felix Hantke; Uppsala universitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; coherent diffractive X-ray imaging; lensless imaging; coherent X-ray diffractive imaging; flash diffractive imaging; single particle imaging; aerosol injection; electrospray injection; substrate-free sample delivery; carboxysome; phase retrieval; X-ray diffraction software; X-ray free-electron laser; XFEL; FEL; CXI; CDI; CXDI; FXI;

    Abstract : The newly emerging technology of X-ray free-electron lasers (XFELs) has the potential to revolutionise molecular imaging. XFELs generate very intense X-ray pulses and predictions suggest that they may be used for structure determination to atomic resolution even for single molecules. READ MORE

  2. 2. 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

  3. 3. Flash Diffractive Imaging in Three Dimensions

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tomas Ekeberg; Uppsala universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray; diffraction; mimivirus; three dimensional; phase retrieval; EMC; manifold embedding; CXI; FEL; free-electron laser; single particle; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : During the last years we have seen the birth of free-electron lasers, a new type of light source ten billion times brighter than syncrotrons and able to produce pulses only a few femtoseconds long. One of the main motivations for building these multi-million dollar machines was the prospect of imaging biological samples such as proteins and viruses in 3D without the need for crystallization or staining.

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

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Gijs van der Schot; Uppsala universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Coherent diffractive X-ray imaging; flash X-ray imaging; lensless imaging; single particle imaging; cyanobacteria; phasing; image classification; substrate-free sample delivery; X-ray free-electron laser; XFEL; FEL; CDXI; CDI; CXI; FXI; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    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

  5. 5. Ultrafast Coherent X-ray Diffractive Nanoimaging

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Filipe R. N. C. Maia; Uppsala universitet.; [2010]
    Keywords : XFEL; Phasing; Image Reconstruction; Single Particle Imaging; Ultrafast Diffraction; X-ray diffraction; Coherent Diffractive Imaging; CXDI;

    Abstract : X-ray lasers are creating unprecedented research opportunities in physics,chemistry and biology. The peak brightness of these lasers exceeds presentsynchrotrons by 1010, the coherence degeneracy parameters exceedsynchrotrons by 109, and the time resolution is 105 times better. READ MORE
