2. Interactions of chiral ions and molecules in gas phase : Towards an understanding of chiral recognition mechanism
Abstract : This thesis comprises the research related to interactions of enantiopure amino acids with chiral and achiral molecules in gas phase. The investigation of the mechanism responsible for chiral discrimination is of the special interest in this work. READ MORE

3. Method and technique development in peptide and protein mass Spectrometry
Abstract : Mechanistic studies and applicability of several methods and techniques for studying peptides and proteins with mass spectrometry are presented. A model for the protein molecular ion formation in explosive matrix-assisted plasma desorption mass spectrometry is proposed, involving a contribution from the chemical energy release during conversion of the explosive, an enhanced protonation through collisions with products from the explosive decay, and electron scavenging by other products.

5. Neutron Emission Spectrometry for Fusion Reactor Diagnosis : Method Development and Data Analysis
Abstract : It is possible to obtain information about various properties of the fuel ions deuterium (D) and tritium (T) in a fusion plasma by measuring the neutron emission from the plasma. Neutrons are produced in fusion reactions between the fuel ions, which means that the intensity and energy spectrum of the emitted neutrons are related to the densities and velocity distributions of these ions.
