1. Application of Laser Techniques for Combustion Studies
Sammanfattning : The aim for this work has been to increase the applicability of laser spectroscopy techniques for studies of combustion processes, both what regards in-flame experiments, exhaust-gas analysis and remote sensing of the atmosphere. Raman spectroscopy has been used for analysis of exhaust gases from flames, model fires of wood and for inflame measurements. LÄS MER
2. Laser Spectroscopic Techniques for Combustion Diagnostics Directed Towards Industrial Applications
Sammanfattning : In the work presented in the thesis, different laser spectroscopic techniques were utilized for measurement of species concentrations, as well as for surface thermometry. Experiments were conducted in various combustion environments, ranging from laboratory burners to truck-sized internal combustion (IC) engines, gas turbine combustors and a full-size aircraft turbofan engine.

3. Laser Diagnostic Techniques with Ultra-High Repetition Rate for Studies in Combustion Environments
Sammanfattning : When conducting laser based diagnostics in combustion environments it is often desirable to obtain temporally resolved information. This can be due to several factors such as combustion taking place in a turbulent flow field, flame propagation from a spark plug in an initially quiescent combustible mixture, or rapid, multi-point fuel consumption in a homogeneous charge as a result of compression ignition in an engine cycle.

4. Optical Functionalization of Transparent Wood Biocomposites
Sammanfattning : Transparent wood (TW) biocomposites combines load-bearing properties with high transmittance of light. TW consists of a reinforcing wood substrate that has been infiltrated with a polymer matrix. TW can be combined with additives so that new multifunctional materials are obtained. LÄS MER
5. Ultrafast, Non-Equilibrium Electron Transfer Reactions of Molecular Complexes in Solution
Sammanfattning : Photoinduced electron transfer is a fundamentally interesting process; it occurs everywhere in the natural world. Studies on electron transfer shed light on questions about the interaction between molecules and how the dynamics of these can be utilized to steer the electron transfer processes to achieve a desired goal.
