1. First-principles investigations of planar defects
Abstract : Two types of planar defects, phase interface and stacking fault, are addressed in this thesis. The investigation is mainly carried out for stainless steels which are fundamental materials in modern society. For the phase interface, we investigate the metallic bcc/bcc and fcc/bcc phase interfaces. READ MORE

2. First-principles investigations of planar defects
Abstract : Two types of planar defects, phase interface and stacking fault, are addressed in thisthesis. The first-principles exact-muffin orbitals method in combination with thecoherent-potential approximation is the main density functional theory (DFT) toolfor our studies. READ MORE

3. Ab Initio Investigation of Interfacial and Grain Boundary Properties of Metals and Alloys
Abstract : Phase interface (IF) and grain boundary (GB) are both common yet critical planar defects influencing the mechanical and physical properties of polycrystalline materials. Due to the complex nature of IFs and GBs in terms of structure and chemistry, determining the accurate excess energies associated with these defects is challenging for both experimental measurements and theoretical simulations.

5. Genetic organization of encapsulated and non-encapsulated Haemophilus influenzae strains. Analysis of the glpTQ and 23S rRNA operons
Abstract : Encapsulated Haemophilus influenzae type b (Hib) and non-encapsulated H. influenzae (NTHi) are important pathogens causing invasive and mucosal infections in children. A 42 kDa surface-exposed lipoprotein, protein D, has been found to be a potential virulence factor of NTHi. READ MORE
