2. Ab initio Interlayer Potentials For Metals and Alloys
Abstract : Many modern materials and material systems are layered. The properties related to layers are connected to interactions between atomic layers. In the present thesis, we introduce the interlayer potential (ILP), a novel model potential which fully describes the interaction between layers. READ MORE

3. Significance of grain boundaries for transport phenomena in graphene and proton-conducting barium zirconate
Abstract : Grain boundaries can have a significant influence on the properties of polycrystalline materials. When determining the type and extent of this influence it is frequently useful to employ computational methods such as density functional theory and molecular dynamics, which can provide models of the grain boundary structure at the atomistic level.

4. Atomistic simulation and experimental studies of transition metal systems involving carbon and nitrogen
Abstract : The present work was initiated to investigate the stability, structural and thermodynamic properties of transition metal carbides, nitrides and carbo-nitrides by atomistic simulations and experimentations. The interatomic pair potentials of Cr-Cr, Mn-Mn, Fe-Fe, C-C, Cr-C, Mn-C, Fe-C, Cr-Fe, Cr-N and Mn-N were inverted by the lattice inversion method and ab initio cohesive energies, and then employed to investigate the properties of Cr-, Mn- and Fe-carbides by atomistic simulations in this work.

5. Atomistic modeling of interfaces in WC-Co cemented carbides
Abstract : Grain and phase boundaries are crucial in understanding the properties of real materials. In this thesis, interfaces in WC–Co cemented carbide are modeled atomistically using density functional theory (DFT) and analytic interatomic potentials. READ MORE
