2. 1. Biological Laboratory X-Ray Microscopy

   Author : Mikael Kördel; Hans Hertz; Ulrich Vogt; Jonas A. Sellberg; Rajmund Mokso; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-ray microscopy; laboratory x-ray microscopy; water window; biological; cell imaging; virus; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik; Optik och fotonik; Optics and Photonics;

   Abstract : Soft x-ray microscopy in the water window (? ≈ 2.3 − 4.3 nm) is a powerful technique for high-resolution biological imaging. The strong natural contrast between carbon-based structures and water allows visualization of hydrated and unstained samples, while providing enough transmission through up to ∼ 10 μm of organic matter.

4. 2. Compact Soft X-Ray Microscopy: Image Processing and Instrumentation

   Author : Heide Stollberg; Hans Hertz; Jürgen Thieme; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray microscopy; Physics; Fysik;

   Abstract : Soft x-ray microscopy is a powerful technique for natural-contrast, high-resolution imaging of organic materials. This Thesis describes new instrumentational and new image-processing methods to improve the image quality of the compact x-ray microscope at the Biomedical & X-Ray Physics division at KTH. READ MORE

5. 3. Growth and Nano-structural Studies of Metallic Multilayer for X-ray Mirrors

   Author : Naureen Ghafoor; Jens Birch; Gabriella Andesson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soft X-rays; Multilayer Mirrors; X-ray microscope; Materials science; Teknisk materialvetenskap;

   Abstract : A part of the Ph.D. project focused on growth and characterization of metal multilayers is presented in this licentiate thesis. The main interest in carrying out this research is to develop highly reflective normal-incidence condenser mirrors for soft X-ray microscopy studies in the water window (λ=2. READ MORE

6. 4. Amorphous, Nanocrystalline, Single Crystalline: Morphology of Magnetic Thin Films and Multilayers

   Author : Andreas Liebig; Björgvin Hjörvarsson; Gabriella Andersson; Frank Klose; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Multilayer; Superlattice; X-ray diffraction; X-ray reflectometry; electron diffraction; Rutherford backscattering spectrometry; Interdiffusion; thin film growth; transmission electron microscopy; Epitaxial growth; Fysik; Physics; Fysik;

   Abstract : Properties of magnetic thin film devices cannot be understood without detailed knowledge of their structure. For this purpose, a variety of thin film and multilayer systems have been studied. READ MORE

7. 5. Multiscale X-ray Characterisation of Cellulose-based Solid Dispersions

   Author : Martina Olsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PXCT; WAXS; pharmaceutical formulations; multiscale characterisation; STXM; radiation damage; SAXS; X-ray imaging; solid dispersions; cellulose;

   Abstract : Cellulose-based solid dispersions are a promising formulation strategy for providing controlled drug release and dissolution enhancement of poorly soluble drugs. These dispersions can from structures on multiple length scales which can have both positive and negative effects on the functional properties of the formulation. READ MORE
