1. Coherent Diffractive Imaging with X-ray Lasers
Detta är en avhandling från Uppsala : Acta Universitatis UpsaliensisSammanfattning : 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
2. Laboratory x-ray fluorescence tomography
Detta är en avhandling från Stockholm : KTH Royal Institute of TechnologySammanfattning : X-ray fluorescence (XRF) tomography is an emerging bio-imaging modality with potential for high-resolution molecular imaging in 3D. In this technique the fluorescence signal from targeted nanoparticles (NPs) is measured, providing information about the spatial distribution and concentration of the NPs inside the object. LÄS MER
3. Imaging Living Cells with an X-ray Laser
Detta är en avhandling från Uppsala : Acta Universitatis UpsaliensisSammanfattning : 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. LÄS MER
4. Laboratory X-Ray Phase-Contrast Imaging Methods and Comparisons
Detta är en avhandling från Stockholm : KTH Royal Institute of TechnologySammanfattning : X-ray phase-contrast imaging has seen rapid development in recent decades due to its superior performance in imaging low-absorption objects, compared to traditional attenuation x-ray imaging. Having higher demand on coherence, x-ray phase-contrast imaging is performed mostly at synchrotrons. LÄS MER
5. Laboratory soft x-ray microscopy and tomography
Detta är en avhandling från Stockholm : KTH Royal Institute of TechnologySammanfattning : Soft x-ray microscopy in the water-window (λ = 2.28 nm – 4.36 nm) is based on zone-plate optics and allows high-resolution imaging of, e.g. LÄS MER
