1. Formation of nanoparticles by laser-activated processes
Sammanfattning : Due to the small dimensions, nanoparticles and materials consisting of nano-sized building blocks exhibit unique — mostly superior — properties, well differing from their bulk counterpart. Most of the novel properties of nanoparticles (and nanomaterials) are size-dependent, while the majority of the common gasphase methods used for generation of nanopowders result in different, usually wide, size-dispersions.

2. Development of Metal–Organic Frameworks for Catalysis : Designing Functional and Porous Crystals
Sammanfattning : Metal–organic frameworks, or MOFs, have emerged as a new class of porous materials made by linking metal and organic units. The easy preparation, structural and functional tunability, ultrahigh porosity, and enormous surface areas of MOFs have led to them becoming one of the fastest growing fields in chemistry. LÄS MER
3. Structure and chemical ordering in metallic nanoparticles from atomic scale modeling
Sammanfattning : In the last decades, a wide range of attractive properties have put metallic nanoparticles in the spotlight. These properties, often related to optical response and catalytic performance, are to a large extent dependent on structure and chemical ordering, that is, the distribution of elements in the nanoparticle.

4. Highly Efficient CIGS Based Devices for Solar Hydrogen Production and Size Dependent Properties of ZnO Quantum Dots
Sammanfattning : Materials and device concepts for renewable solar hydrogen production, and size dependent properties of ZnO quantum dots are the two main themes of this thesis.ZnO particles with diameters less than 10 nm, which are small enough for electronic quantum confinement, were synthesized by hydrolysis in alkaline zinc acetate solutions.

5. Kinetic Measurements Using Nanoplasmonic Sensing
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
