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

   Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

   Författare :Max Felix Hantke; Filipe R. N. C. Maia; Janos Hajdu; Martin Svenda; Edgar Weckert; [2016]
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
