1. Photocatalysis beyond conventional precious metal complexes
Sammanfattning : Precious metals, e.g. Ru and Ir, are expensive, scarce and non-renewable resources. As oppose to many renewable resources, these cannot be deliberately produced wherever one wishes. LÄS MER
2. Functionalized mesoporous carbons as non-precious metal fuel cell catalysts
Sammanfattning : Fuel cells allow for clean and efficient chemical to electrical energy conversion. However, their high price significantly limits the market viability of the technology. This is to a large part due to the high cost of the precious metals used in most fuel cell catalysts. LÄS MER
3. Carbenes: The Gathering : Photophysics of Transition Metal Carbene Complexes
Sammanfattning : This thesis explores the photophysics of some transition-metal complexes (TMCs) which utilize N-heterocyclic carbenes as ligands. After a historical interlude which traces the development of the broader field of transition metal complexes and their photophysical investigations, there is an overview of theoretical concepts and the spectroscopic methods employed.

4. Colloidal synthesis of metal nanoparticles
Sammanfattning : Metal nanoparticles (NPs) are central in a wide range of industrial areas including catalytic and biomedical applications. Due to their interesting physical properties, the demand of these precious materials is steadily increasing, which has created a need for the development of effective and high-performing NPs. LÄS MER
