1. Development and Application of Rotational Coherent Anti-Stokes Raman Spectroscopy and Laser-induced Fluorescence for Combustion Diagnostics
Sammanfattning : The thesis concerns the development and application of two laser-based methods for combustion diagnostics: dual broadband rotational coherent anti-Stokes Raman spectroscopy (CARS) and laser-induced fluorescence (LIF). In efforts to increase the usefulness of the CARS technique, the applicability of a method involving a combination of the rotational CARS technique and the closely related vibrational CARS technique was investigated.

2. Development and application of laser diagnostics - from laboratory devices towards practical combustion engines
Sammanfattning : For many decades, research work on combustion has been focused on improving combustion efficiency and reducing harmful emissions. Laser diagnostics is one of the best ways to investigate the combustion process and emission formation as it is non-intrusive and it has high spatiotemporal resolution. LÄS MER
3. Optimizing Enzyme Immobilization in Mesoporous Silica - A Spectroscopic Study of the Dynamics and Spatial Distribution of the Confined Enzymes
Sammanfattning : Enzymes as biological catalysts are immobilized in porous materials to improve the enzyme activity and simplify their purification from the reaction media in biocatalytic applications. Mesoporous silica (MPS) particles are used as a promising support material for the immobilization of enzymes. LÄS MER
4. OH and Soot Optical Diagnostics for Combustion Applications for Combustion Applications
Sammanfattning : Optical diagnostics are remote non-intrusive sensing techniques. The thesis work concerns the use of OH and soot optical diagnostics for combustion research.Internal combustion (IC) engines are widely used for the generation of power and for transportation purposes. LÄS MER
5. Stochastic Reactor Models for Engine Simulations
Sammanfattning : The aim of the thesis work is the further development of practical engine simulation tools based on Stochastic Reactor Models, SRMs. Novel and efficient implementations were made of a variety of SRMs adapted to different engine types. The models in question are the HCCI-SRM, the TwoZone SI-SRM and the DI-SRM. LÄS MER
