   Sammanfattning : In this thesis, new silver(I) nitrate compounds with N-donor heterocyclic ligands are described. The structures of the obtained crystalline compounds 1-19 were analysed using X-ray single-crystal diffraction. LÄS MER

7. 5. Studies of systems related to high-Tc superconductors by electron microscopy and X-ray powder diffraction

   Författare :Ingrid Bryntse; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : New cuprate systems related to high temperature superconductors have been investigated and are reviewed. The synthesized samples have been studied mainly by transmission electron microscopy, energy-dispersive spectrometry and X-ray powder diffraction, in order to determine composition and structure of the formed phases.
