1. Formation and Decomposition of Platinum–Thallium Bond, Kinetics and Mechanism. Structural Characterization of Some Metal Cyanides in the Solid State
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 mixandmeasurespectrophotometric technique and stoppedflow method.These reactions are interpreted as oxidative addition of the cspecies to the square planar Pt(CN)42-complex.

2. Time-Resolved X-ray Diffraction Studies of Laser-Induced Dynamics in Solids
Sammanfattning : X-ray diffraction is an invaluable tool in the field of structural dynamics. In the work described in this thesis, time-resolved X-ray diffraction experiments were carried out to investigate ultrafast lattice dynamics. LÄS MER
3. Metastable YAlN and ScAlN thin films : growth and characterization
Sammanfattning : ScxAl1-xN and YxAl1-xN thin films were deposited in a ultra high vacuum system using reactive magnetron co-sputtering from elemental Al, Sc and Y targets in Ar/N2. Their mechanical, electrical, optical, and piezoelectrical properties were investigated with the help of transmission electron microscopy, xray diffraction, ellipsometry, I-V and C-V measurements, and two different techniques for piezoelectric characterization: piezoresponse force microscopy and double beam interferometry.

4. Reconstruction of Holocene atmospheric mineral dust deposition from raised peat bogs in south–central Sweden
Sammanfattning : Atmospheric mineral dust plays a dynamic role in the climate system acting both as a forcing and a feedback mechanism. To date, the majority of paleodust studies have been conducted on marine sediments or polar ice cores, while terrestrial deposition has been less studied. LÄS MER
5. Interactions between iron oxides and the additives quartzite, calcite and olivine in magnetite-based pellets
Sammanfattning : In the present study, magnetite pellets with large amounts of the additives olivine, calcite and quartzite were isothermally reduced in a tubular furnace to study the interaction between iron oxides and the additives. A first attempt at using exaggerated amounts of additives was made in order to enable analyses of phases that do not otherwise occur in sufficient amounts for Xray diffraction and EDS-analyses.
