  2. 1. Time-resolved x-ray diffraction of nanostructured samples

    Author : A. I. H. Persson; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; x-ray diffraction; phonons; optoacoustic transducer; electron diffusion; nanowires; Fysicumarkivet A:2016:Persson;

    Abstract : The work presented in this thesis is based on time-resolved x-ray diffraction studies of InSb (111) samples. The experiments were carried out using a pump-probe configuration using short laser pulses as the pump and x-rays as the probe. Laser excitation leads to the formation of a strain pulse that propagates through the sample. READ MORE

  4. 2. X-ray scattering and spectroscopy of supercooled water and ice

    Author : Jonas A. Sellberg; Anders Nilsson; Lars G. M. Pettersson; Thomas Loerting; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supercooled water; ice; x-ray scattering; x-ray spectroscopy; free-electron laser; kemisk fysik; Chemical Physics;

    Abstract : This thesis presents experimental studies of water and ice at near-atmospheric pressures using intense x-rays only accessible at synchrotrons and free-electron lasers. In particular, it focuses on the deeply supercooled, metastable state and its implications on ice nucleation. READ MORE

  5. 3. Plasma and Dust around Icy Moon Enceladus and Comet 67P/Churyumov-Gerasimenko

    Author : Ilka. A. D. Engelhardt; Anders Eriksson; Ingrid Mann; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : Saturn's moon Enceladus and comet 67P/Churyumov-Gerasimenko both are examples of icy solar system objects from which gas and dust flow into space. At both bodies, the gas becomes partly ionized and the dust grains get charged. READ MORE

  6. 4. Effects of drought on boreal forest understory species

    Author : Irena A. Koelemeijer; Kristoffer Hylander; Johan Asplund; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity conservation; boreal forests; bryophytes; canopy cover; climate change; drought; extreme climatic events; forest management; forest understory; fungi; lichens; plants; rainout shelter; soil communities; soil moisture; transplant experiment; Ecology and Evolution; ekologi och evolution;

    Abstract : Extreme climatic events, such as droughts, can have large effects on biodiversity. Drought effects in forest understories are variable over small spatial scales and can be exacerbated, or buffered, by the local vegetation structure, distance to forest edges, hydrology, and soil characteristics.

  7. 5. Plasma and Dust at Saturn's Icy Moon Enceladus and Comet 67P/Churyumov-Gerasimenko

    Author : Ilka. A. D. Engelhardt; Anders I. Eriksson; Yoshifumi Futaana; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik med inriktning mot rymd- och plasmafysik; Physics with specialization in Space and Plasma Physics;

    Abstract : Saturn’s moon Enceladus and comet 67P/Churyumov-Gerasimenko both are examples of icy solar system objects from which gas and dust flow into space. At both bodies, the gas becomes partly ionized and the dust grains get charged. READ MORE
