  4. 2. Advances in Soft Matter Nanofabrication

    Author : Mehrnaz Shaali; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photolithography; negative e-beam resist; monolayer; confocal microscopy; Teflon AF; KPFM; DNA origami; cells; lipid nanotube; AFM; double bilayer; Phospholipid; electron beam lithography;

    Abstract : The focus of this thesis is placed on the fabrication of engineered nanodevices for the manipulation of soft matter thin films. By combining top-down micro- and nanofabrication approaches with bottom-up self-assembly strategies, new research platforms were developed, tested and characterized. READ MORE

  5. 3. A Stacked Prism Lens Concept for Next-Generation Hard X-Ray Telescopes

    Author : Wujun Mi; Mats Danielsson; Peter Nillius; Ralf K. Heilmann; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; focusing X-ray telescopes; Wolter-I optics; stacked prism lens; focused UV lithography; grayscale e-beam lithography; proximity effect correction; angular resolution; effective collecting area; röntgenteleskop; Wolter-I-optik; staplade prismalinser; fokuserad UV-litografi; elektronstråle-litografi; Fysik; Physics;

    Abstract : Over the past half century, the focusing X-ray telescope has played a very prominent role in X-ray astronomy at the frontier of fundamental physics. The finer angular resolution and increased effective area have enabled more and more exciting discoveries and detailed studies of the high-energy universe, including the cosmic X-ray background (CXB) radiation, black holes in active galactic nuclei (AGN), galaxy clusters, supernova remnants, and so on.

    Author : J. Michael Larsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; array illuminators; computer generated phase holograms; computer simulations; diffractive bifocal intraocular lenses; kinoforms; design; manufacture; diffractive optical elements; evaluation; simulation;

    Abstract : This work deals with the design, simulation, manufacture, and evaluation of diffractive optical elements. Particularly, kinoforms and diffractive bifocal intraocular lenses are studied. Evaluation of kinoforms, i.e. READ MORE

  7. 5. Liquid-Jet-Target Microfocus X-Ray Sources : Electron Guns, Optics and Phase-Contrast Imaging

    Author : Tomi Tuohimaa; Hans M. Hertz; Stephen Wilkins; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; electron-impact; x-ray; brightness; liquid-jet-target; phase-contrast imaging; Engineering physics; Teknisk fysik;

    Abstract : This Thesis describes the development of an electron-impact microfocus x-ray source and its application for phase-contrast imaging. The source is based on a novel, liquid-jet target concept. Stable and continuous operation can be achieved at substantially higher electron-beam power densities than conventional solid target based systems. READ MORE
