2. 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.

3. 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

4. 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

5. Simulation of radiation damage in Fe and Fe-Cr
Abstract : Steel is an important structural material in nuclear reactors used for example in pressure vessels and fast reactor cladding. In reactor environments it has been observed that ferritic steels are more resistant to swelling than the austenitic steels typically used. READ MORE
