2. Excitation and Ground-State Properties of Natural and Modified Nucleic Acid Bases
Abstract : The nucleic acid bases are the carriers of genetic information in DNA and RNA. They are also the main chromophores of nucleic acids and determine their optical properties and sensitivity to UV radiation. READ MORE

3. Optical Diagnostics of Non-thermal Plasmas and Plasma-assisted Combustion
Abstract : Non-thermal plasma is regarded as a collection of free electrons, ions and neutral particles that are not at local thermodynamic equilibrium. The high-energetic electrons formed in non-thermal plasmas are capable of generating chemically active species and modifying chemical kinetics in practical applications. READ MORE

4. Interpretation of gamma-ray burst X-ray and optical afterglow emission : From the central engine to the circumburst interaction
Abstract : Gamma-ray bursts are the largest electromagnetic explosions known to happen in the Universe and are associated with the collapse of stellar progenitors into blackholes. After an energetic prompt emission phase, lasting typically less than a minute and emitted in the gamma-rays, a long-lived afterglow phase starts. READ MORE

5. Methods, Instrumentation and Mechanisms for Optical Characterization of Tissue and Treatment of Malignant Tumours
Abstract : In this thesis, different optical methods utilising visible light for characterization of tissue have been developed and evaluated. The feasibility of many of these methods has been demonstrated in the laboratory or in animal experiments. READ MORE
