  1. 1. On-line Electrochemistry Electrospray Ionisation Mass Spectrometry : Method Development and Applications

    Författare :Camilla Zettersten; Leif Nyholm; Per Sjöberg; Andries P. Bruins; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi; Analytical Chemistry; analytisk kemi;

    Sammanfattning : This thesis deals with studies of on-line electrochemistry electrospray ionisation mass spectrometry (EC/ESI-MS). It is shown that the use of EC/ESI-MS demands optimal coupling characteristics. Pre-concentration and desalting, due to matrix exchange, were demonstrated for the model substance 1-hexanethiol in an EC/ESI-MS setup. LÄS MER

    Sammanfattning : Catalytic processes are present in a wide range of aspects, from fundamental biological processes to modern chemical synthesis. In practical terms, catalysis has thrived as a rapidly growing industry. LÄS MER

  4. 3. Formation and Decomposition of Platinum–Thallium Bond, Kinetics and Mechanism. Structural Characterization of Some Metal Cyanides in the Solid State

    Författare :Péter Nagy; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal–metal bond; platinum; thallium; kinetics; mechanism; stopped flow; oxidative addition; cyano complexes; edta; redox reaction; metal cyanides; X–ray diffraction; Raman; NMR; mercury; palladium; nickel; one dimensional wire;

    Sammanfattning : The kinetic and mechanistic features of a new series ofplatinum-thallium cyano compounds containing a direct andunsupported by ligands metal-metal bond have been studied insolution, using standard mix–and–measurespectrophotometric technique and stopped–flow method.These reactions are interpreted as oxidative addition of the cspecies to the square planar Pt(CN)42-complex.
