  1. 1. Subvalent Cluster Compounds and Synthesis in Alternative Reaction Media

    Författare :Josefin Åkerstedt; Lars Kloo; Mats Johnsson; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal cluster; Zintl ion; metal-organic sandwich complex; ionic liquid; X-ray diffraction; spectroscopy; crystal structure; Inorganic Chemistry;

    Sammanfattning : With the aim of finding alternative reaction media for the synthesis of subvalent main group and transition metal cluster compounds, traditionally made through solid state reactions or in superacidic media, different alternative reaction media have been explored in this work. Room-temperature ionic liquids are amongst the more unconventional reaction media used. LÄS MER

  5. 4. Simulation of the Melting and Cooling of Palladium Clusters

    Författare :Jan Westergren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; melting; energy transfer; density of states; metal clusters; cooling; collision; phase barrier; sticking;

    Sammanfattning : The thermal behaviour of palladium clusters has been investigated using Monte Carlo simulation in various ensembles. Furthermore the energy transfer between palladium clusters and rare gas atoms has been calculated in simulated collisions aiming for a calculation of the cooling of clusters in a rare gas atmosphere.
