  2. 1. Ultrafast Coherent X-ray Diffractive Nanoimaging

    Author : Filipe R. N. C. Maia; Janos Hajdu; David van der Spoel; Keith Nugent; Uppsala universitet; []
    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

  4. 2. Algorithms for Coherent Diffractive Imaging with X-ray Lasers

    Author : Benedikt J. Daurer; Filipe Maia; Tomas Ekeberg; Janos Hajdu; Richard Neutze; Uppsala universitet; []
    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

  5. 3. Coherent Diffractive Imaging with X-ray Lasers

    Author : Max Felix Hantke; Filipe R. N. C. Maia; Janos Hajdu; Martin Svenda; Edgar Weckert; Uppsala universitet; []
    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

  6. 4. Towards Fast and Robust Algorithms in Flash X-ray single-particle Imaging

    Author : Jing Liu; Stefan Engblom; Filipe Maia; Janos Hajdu; Helmut Grubmüller; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X-ray Free Electron lasers XFELs ; 3D electron density determination; Machine learning; Image processing; High-performance computing; GPUs; Uncertainty quantification; X-ray single-particle Imaging; Flash X-ray single-particle diffraction Imaging FXI ; ; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Modern X-ray Free Electron Laser (XFEL) technology provides the possibility to acquire a large number of diffraction patterns from individual biological nano-particles, including proteins, viruses, and DNA. Ideally, the collected data frames are high-quality single-particle diffraction patterns. READ MORE

  7. 5. Small Particles with Big Impact : Structural Studies of Viruses and Toxicological Studies of Nanodiamonds

    Author : Anna Munke; Marvin Seibert; Kenta Okamoto; Filipe Maia; Inger Andersson; Nicola Stonehouse; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Chaetenuissarnavirus II; cryo-EM; CtenRNAV-II; Escherichia coli; Danio rerio; flash X-ray imaging; Marnaviridae; single-particle analysis; single-particle imaging; Sogarnavirus; virus evolution; virus structure; XFEL; zebrafish embryo; Physics with specialization in Biophysics; Fysik med inriktning mot biofysik;

    Abstract : Nanoparticles (NPs) can be found everywhere and their existence has both beneficial and harmful consequences for the environment and living beings. The investigations on which this thesis is based upon have contributed to an increased understanding of some of these particles and to the development of a method that could be used to study their structure.
