  2. 11. Nanowire devices for X-ray detection

    Author : Lert Chayanun; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nanowires; Nanowire solar cells; X-ray detectors; X-ray beam induced current;

    Abstract : High spatial resolution X-ray microscopy has become a dedicated tool to study nanocrystals and nanostructure devices in recent years. In general, the spatial resolution of X-ray microscopy depends on the spot size of the X-ray beam and the pixel size of X-ray detectors. READ MORE

    Abstract : Collagen is the main organic building block of musculoskeletal tissues. Despite collagen being their smallest load bearing unit, these tissues differ significantly in mechanical function and properties. A major factor behind these differences is their hierarchical organization, from the collagen molecule up to the organ scale. READ MORE

  5. 13. Photon Counting X-ray Detector Systems

    Author : Börje Norlin; Christer Fröjdh; Hans-Erik Nilsson; Kenway Smith; Mittuniversitetet; []

    Abstract : This thesis concerns the development and characterisation of X-ray imaging systems based on single photon processing. “Colour” X-ray imaging opens up new perspectives within the fields of medical X-ray diagnosis and also in industrial X-ray quality control. READ MORE

  7. 15. Small-Animal Imaging with Liquid-Metal-Jet X-Ray Sources

    Author : Daniel Larsson; Hans Hertz; Anna Burvall; David Paterson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray; x-ray imaging; small animal; phase contrast; tomography; Fysik; Physics;

    Abstract : Small-animal x-ray imaging is an important tool for medical research. The penetration power of x-rays makes it possible to investigate the 3D structure of small animals and other thick biological samples by computed tomography (CT). READ MORE
