    Sammanfattning : This thesis is devoted to detailed studies of element 115 decay chains using the highly efficient multi-coincidence alpha, electron, gamma and X-ray detector setup TASISpec at the gas-filled separator TASCA at GSI, Darmstadt, Germany. In a three-week long experiment thirty new decay chains assumed to stem from element 115 isotopes were observed together with the very first detections of gamma rays and potential X-rays from these nuclei.

  5. 4. Molecular Structure and Packing of Platinum(II) Complexes with S-donor Ligands in the Solid State An X-ray Crystallographic Study

    Författare :Christian Hansson; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; low temperature; high-pressure; structural class concept; hydrogen bonding; intermolecular interactions; crystallography; platinum coordination compounds; packing; phase transitions; Inorganic chemistry; Oorganisk kemi;

    Sammanfattning : How do molecules arrange themselves in a crystal? It is today not possible to definite predict the three-dimensional packing arrangement of molecules in the crystalline solid state. The aim of the work presented in this thesis has been to gain more knowledge of what principles that govern molecular packing. LÄS MER

  7. 5. Phase-Contrast X-Ray Carbon Dioxide Angiography

    Författare :Ulf Lundström; Hans Hertz; Anna Burvall; Ulrich Vogt; Franz Pfeiffer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Phase-contrast x-ray imaging is an emerging technology, which allows for imaging of smaller features than conventional absorption-based x-ray imaging, with lower radiation dose. Instead of the attenuation that is normally used in x-ray imaging, it utilizes the phase shift introduced by an object to the transmitted x-rays. LÄS MER
