  2. 1. On Thallium (III) and binuclear platinum-thallium complexes with N-donor ligands in solution and in solid

    Author : Guibin Ma; KTH; []
    Keywords : thallium; platinum; cyanide; n-donor ligand; metal-metal bond multinuclear NMR; raman spectroscopy;

    Abstract : This thesis describes the synthesis, structure, equilibriaand other properties of novel thallium(III) monomeric andplatinum-bonded complexes with nitrogen donor ligandsethylenediamine, diethylenetriamine, triethylenetetramine,porphyrin, 2,2'-bipyridine and 1,10-phenanthroline in solutionand in solid.The existence of three complexes withthe general formula[Tl(en)n]3+(n = 1-3) and their overall stability constantshave been established in pyridine.

  4. 2. Structural Dynamics of Glass-Forming Liquids

    Author : Dennis Engberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Neutron and light scattering experiments on glass-forming liquids, an oxide network, a polymeric system and a polymeric electrolyte, were performed. The network glass-former B2O3 was investigated from 60 - 1300 K. The experimental results were interpreted using mode coupling theory and the soft potential model. READ MORE

  5. 3. Aqueous Solutions as seen through an Electron Spectrometer : Surface Structure, Hydration Motifs and Ultrafast Charge Delocalization Dynamics

    Author : Niklas Ottosson; Svante Svensson; Olle Björneholm; Gunnar Öhrwall; Clemens Heske; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Water; Aqueous solutions; Ions; Molecular Hydration; Electron dynamics; Atmospheric Chemistry; Hydrolysis; Acid-Base Chemistry; Interatomic Coulombic Decay; ICD; Liquid Micro-Jet; X-ray Photoelectron Spectroscopy; XPS; Auger Electron Spectroscopy; AES; MAX-lab; BESSY; Physics; Fysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : In spite of their high abundance and importance, aqueous systems are enigmatic on the microscopic scale. In order to obtain information about their geometrical and electronic structure, simple aqueous solutions have been studied experimentally by photo- and Auger electron spectroscopy using the novel liquid micro-jet technique in conjunction with synchrotron radiation.

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

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

    Abstract : 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. READ MORE

  7. 5. Charge Development at Iron Oxyhydroxide Surfaces : The Interplay between Surface Structure, Particle Morphology and Counterion Identity

    Author : Philipp A. Kozin; Jean-François Boily; Michael Kersten; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Iron oxyhydroxides; adsorption; mineral-water interface; electrolyte; surface roughness; pores;

    Abstract : Iron (oxyhydr)oxide (FeOOH) minerals play important roles in various natural, technological and societal settings. The widespread abundance of these minerals has prompted numerous studies on their surface reactivity in aqueous media. Surface charge development, one that namely takes place through the adsorption of potential determining ions (p.d. READ MORE
