  2. 6. Compact Soft X-Ray Microscopy : Sources, Optics and Instrumentation

    Author : Per Takman; Hans Hertz; Janos Kirz; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; soft x-ray microscopy; water window; compact; laser plasma; liquid jet; zone plate optics; Physics; Fysik;

    Abstract : This thesis describes the development of a sub-60-nm full-period resolution compact soft x-ray microscope operating in the water-window region (2.3-4.4 nm). Soft x-ray water-window microscopy is a powerful technique for high-resolution imaging of organic materials exploiting the natural contrast mechanism between carbon and oxygen, cf. READ MORE

  4. 7. Simulations of ultrafast photon-matter interactions for molecular imaging with X-ray lasers

    Author : Ibrahim Eliah Dawod; Nicusor Timneanu; Carl Caleman; Adrian P. Mancuso; Lars Schäfer; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray free-electron laser; molecular dynamics; radiation damage; plasma simulations; density functional theory¸ coherent diffractive imaging; protein structure; X-ray crystallography; single particle imaging;

    Abstract : Biological structure determination has had new avenues of investigation opened due to the introduction of X-ray free-electron lasers (XFELs). These X-ray lasers provide an extreme amount of photons on ultrafast timescales used to probe matter, and in particular biomolecules. READ MORE

  5. 8. Structural Studies of Large dsDNA Viruses using Single Particle Methods

    Author : Hemanth Kumar Narayana Reddy; Martin Svenda; Sarah Butcher; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PR772; phage; PRD1; Bacteriophage; coliphage; Melbournevirus; Cedratvirus; lurbo; Pithovirus; CryoEM; Single particle imaging; Coherent; Diffractive; Imaging; Soft X-ray; Microscopy; Microscope; GDVN; High resolution; XFEL; aerosol; Injection; electrospray; gas dynamic virtual nozzle; CDI; CXI; FEL; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Abstract : Structural studies of large biological assemblies pose a unique problem due to their size, complexity and heterogeneity. Conventional methods like x-ray crystallography, NMR, etc. are limited in their ability to address these issues. To overcome some of these limitations, single particle methods were used. READ MORE

  6. 9. 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.
