1. Supported Mono- and Bimetallic Gold Nanoparticle Catalysts for Different Organic Transformations
Sammanfattning : Supported gold nanoparticles are emerging as an important class of catalysts for various organic transformations due to their tunable properties. This thesis embraces the fundamental studies of supported gold nanoparticles for different organic reactions from the viewpoint of understanding the role of synthesis methods, nature of carriers, and addition of second metal on the properties and functions of gold catalysts.

2. Nanoparticle Plasmons in Classic and Novel Materials - Fundamentals and Hydrogen Sensing
Sammanfattning : The interaction of light with sub-wavelength noble metal nanoparticles and nanostructures has developed into one of the most vibrant themes of nanoscience during the past decade. The optical properties of metal nanoparticles are dominated by so-called nanoparticle plasmons or localized surface plasmon resonances (LSPR). LÄS MER
3. Electrical Transport in Nanoparticle Thin Films of Gold and Indium Tin Oxide
Sammanfattning : Electrical transport properties of nanoparticle gold films made by the gas evaporation method were analysed using resistivity measurements. Low temperature electrical transport measurements showed a cross-over from a temperature range dominated by inelastic scattering to a temperature range dominated by elastic scattering, presumably by grain boundaries.
