  1. 6. Laboratory Soft X-Ray Cryo Microscopy: Source, System and Bio Applications

    Författare :Emelie Fogelqvist; Hans Hertz; David Attwood; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray microscopy; X-ray optics; Instrumentation; Laser plasma; Cryofixation; Tomography; Tomographic reconstruction; Autophagy; Immune synapse; Physics; Fysik; Physics;

    Sammanfattning : Soft x-ray microscopes routinely perform high-resolution 3D imaging of biological cells in their near-native environment with short exposure times at synchrotron radiation facilities. Some laboratory-sized microscopes are aiming to make this imaging technique more accessible to a wider scientific community. LÄS MER

  3. 7. X-ray Fluorescence Spectrometry for Environmental Applications

    Författare :Siwen An; Göran Thungström; Börje Norlin; Richard Brenner; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Heavy metal contamination in environmental applications is particularly important because of its potential impact on associated ecosystems and human health. At present, monitoring of heavy metals is usually done by taking and preparing samples for off-line laboratory measurements. LÄS MER

  4. 8. Virtual histology by laboratory x-ray phase-contrast tomography

    Författare :Jenny Romell; Hans Hertz; Anna Burvall; Julia Herzen; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : Detailed imaging of biological samples is central to different fields of research, as well as for clinical pathology. Classical histology, using light- orelectron microscopy, can generate high-resolution images but is destructive and only gives two-dimensional information. LÄS MER

  5. 9. Preclinical X-Ray Fluorescence Imaging with Multifunctional Nanoparticles

    Författare :Giovanni Marco Saladino; Hans Hertz; Muhammet Toprak; Stefan Andersson-Engels; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : X-ray fluorescence imaging (XFI) is an emerging technique for preclinical studies, characterized by high resolution, specificity, and sensitivity. It relies on nanoparticles (NPs) as contrast agents, which must be constituted of specific elements that match the X-ray source energy for detection. LÄS MER

  7. 10. Electron-Impact Liquid-Jet Water-Window X-ray Sources

    Författare :Peter Anders Skoglund Lindberg; Hans M. Hertz; Oscar Tjernberg; KTH; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This Thesis describes the development and characterization of a soft x-ray liquidjet-anode electron-impact source. With a water-jet target the primary emission is the O Kα line at 525 eV. This is close to the lower edge of the water-window, a spectral region lacking simple laboratory sources. LÄS MER
