  2. 1. Novel in vitro systems elucidating metabolic health and disease

    Author : Joanne X. Shen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The convoluted nature of biology warrants improved models that further insights into health and disease. Bioengineered features and platforms allow the modulation and study of a range of biological phenomena. READ MORE

  4. 2. A new laser-plasma X-ray source for microscopy and lithography

    Author : Lars Rymell; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; X-ray microscopy; X-ray lithography; Atomic and molecular physics; multilayer mirror; Fysicumarkivet A:1997:Rymell; Atom- och molekylärfysik; X-ray source; Laser-produced plasma; liquid droplet; debris-free; water window;

    Abstract : A new high-brightness source for soft X-rays and EUV-radiation has been developed. This laser-plasma source utilizes a microscopic liquid droplet or jet as target. The result is a reduction of debris emission by several orders of magnitude compared to conventional laser plasmas. READ MORE

  5. 3. Laser-Matter Interactions at Extreme Irradiance: X-ray Generation and Relativistic Channelling

    Author : Anders Sjögren; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; relativistic self-focusing; particle acceleration; x-ray generation; radiography; Laserteknik; Laser technology; laser-produced plasma; light scattering; Fysicumarkivet A:2002:Sjögren;

    Abstract : This thesis summarizes experimental work in which the powerful Ti:sapphire lasers at the High Power Laser Facility at the Lund Laser Centre have been employed to investigate laser-produced X-rays and relativistic channelling. These lasers produce short pulses, of the order of 50 fs, with energies ranging from 1 mJ to 1 J. READ MORE

  6. 4. Generation and Applications of Short-Pulse X-ray Radiation

    Author : Michael Harbst; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; egenskaper termiska och mekaniska ; Kondenserade materiens egenskaper:struktur; crystallography; phase equilibria; Material science; Condensed matter:stucture; thermal and mechanical properties; time-resolved; X-ray diffraction; kristallografi; fasjämvikt; Material technology; Materiallära; materialteknik;

    Abstract : This thesis summarizes work using hard X-ray radiation on nanosecond and picosecond timescales. The focus is on the experimental part including detailed descriptions of setups for laser pumped - X-ray probe experiments. X-ray diffraction is sensitive to structural properties on the length scale of chemical bonds. READ MORE

  7. 5. 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
