1. Iron based Li-ion insertion materials for battery applications
Sammanfattning : Li-ion batteries are currently the most efficient technology available for electrochemical energy storage. The technology has revolutionized the portable electronics market and is becoming a corner stone for large scale applications, such as electric vehicles. LÄS MER
2. Synthesis of Covalently Linked Diporphyrins: Model Compounds for Intramolecular Energy and Electron Transfer
Sammanfattning : Three series of donor-bridge-acceptor compounds have been synthesized to probe the influence of various bridge chromophores on energy and electron transfer. The donor-bridge-acceptor compounds in each series comprise two different porphyrins, acting as donor and acceptor, covalently linked by bridge chromophores. LÄS MER
3. Electrical and Frictional Performance of Tin-Coated Contacts Exposed to Wear and Fretting Corrosion
Sammanfattning : The complexity of electronic systems in vehicles is rapidly increasing, and as a consequence, the long-term reliability of automotive connectors has become an important issue. The aims of this thesis have been: 1. to characterize the friction, wear and electrical properties of tin coatings, 2. LÄS MER
4. Cutaneous microdialysis : a technique for human in vivo sampling
Sammanfattning : Microdialysis enables in vivo sampling of endogenous and exogenous substances in the interstitial fluid. A probe equipped with a tubular semi-permeable dialysis membrane is inserted into the skin, and perfused with a physiological solution. LÄS MER
5. C–H and Si–H functionalization using redox-active diazo compounds and decarboxylative coupling
Sammanfattning : The work presented in this thesis is based on two basic organic chemistry concepts: carbene catalysis and radical coupling reactions. Diazo compounds in the presence of transition-metal catalysts are known to be excellent reagents for the construction of C–X bonds (X = C, Si, N, O, etc.) under mild conditions. LÄS MER
