  4. 2. Phase-Contrast and High-Resolution Optics for X-Ray Microscopy

    Author : Olof von Hofsten; Ulrich Vogt; Ian McNulty; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Microscopy; X-ray optics; X-ray microscopy; Soft X-ray physics; Optics; Optik; Physics; Fysik;

    Abstract : X-ray microscopy is a well-established technique for nanoscale imaging. Zone plates are used as microscope objectives and provide high resolution, approaching 10 nm, currently limited by fabrication issues. This Thesis presents zone plate optics that achieve either high resolution or phase contrast in x-ray microscopy. READ MORE

    Abstract : 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. READ MORE

  6. 4. Atomic Scale Degradation of Zirconium Alloys for Nuclear Applications

    Author : Gustav Sundell; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Irradiation damage; Hydrogen microanalysis; Hydrogen pick-up; Zirconium alloys; Atom probe tomography; Corrosion;

    Abstract : Due to their low thermal neutron capture cross-section, zirconium alloys are widely used in the nuclear industry as fuel cladding and for structural components. The lifetime of the fuel assemblies in the reactors is primarily dictated by the ability of the cladding to withstand oxidation and hydrogen pick-up from the coolant water and radiation damage induced by the neutron flux.

  7. 5. Manipulation of Light with Transformation Optics

    Author : Wei Yan; Min Qiu; Niels Asger Mortensen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transformation optics; Maxwell’s equations; invisibility cloaks; compensated bilayer; perfect imaging; optical illusion; nihility media; α media; Optics; Optik;

    Abstract : Transformation optics, a recently booming area, provides people a new approach to design optical devices for manipulating light. With transformation optics, a lot of novel optical devices are proposed, such as invisibility cloaks, optical wormholes, optical black holes, illusion devices. READ MORE
