  1. 1. Structural and Antibacterial Properties of Silver(I) Compounds with N-donor Ligands: A Challenge for Medical Applications

    Författare :Al-Shimaà A A Massoud; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; X-ray diffraction; silver I compounds; solution chemistry; antibacterial activity;

    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

  3. 2. Synthesis and characterisation of heterobimetallic erbium alkoxides

    Författare :Maria Wijk; Jean Galy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : This thesis describes the synthesis and characterisation of alkoxides in the Er-M systems, where M = Al, Ti and Zr. The compounds found have been characterised by IR, UV-Vis DSC and single-crystal X-ray diffraction techniques and by chemical behaviour. LÄS MER

  4. 3. Synthesis and Characterization of Nitrogen-rich Calcium α-Sialon Ceramics

    Författare :Yanbing Cai; Saeid Esmaeilzadeh; Zhijian Shen; Elis Carlström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nitrogen-rich; SiAlON; Sintering; Microstructure; Properties; Inorganic chemistry; Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

    Sammanfattning : In this thesis, a synthesis concept has been developed, which uses nitrogen-rich liquid phases for sintering of Ca-α-sialon ceramics. First, keeping the Si/Al ratios constant, the effects of N/O ratio on the properties and microstructure were investigated through a liquid phase sintering process. LÄS MER

  5. 4. Light-Metal Hydrides for Hydrogen Storage

    Författare :Martin Sahlberg; Yvonne Brandt Andersson; Björgvin Hjörvarsson; Björn Hauback; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Metal-hydrogen compounds; hydrides; hydrogen storage; X-ray diffraction; neutron diffraction; thermal desorption spectroscopy; Chemistry; Kemi; Inorganic chemistry; Oorganisk kemi; Inorganic Chemistry; oorganisk kemi;

    Sammanfattning : Demands for zero greenhouse-gas emission vehicles have sharpened with today’s increased focus on global warming. Hydrogen storage is a key technology for the implementation of hydrogen powered vehicles. LÄS MER

  7. 5. Kinetic Measurements Using Nanoplasmonic Sensing

    Författare :Markus Schwind; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sn Nanoparticles; Sensing; Localized Surface Plasmon Resonances; Particle Plasmon; Metal Oxidation; Metal Corrosion; Solid-Liquid Phase Transition; Kinetics; Al Nanoparticles;

    Sammanfattning : In this thesis the nanoplasmonic sensing technique was used to study kinetics of (i) the oxidation of Al nanoparticles in air and water and (ii) the solid-liquid phase transition in Sn nanoparticles. The nanoplasmonic sensing technique detects changes of the localized surface plasmon resonance (LSPR) in metal nanoparticles. LÄS MER
