Selective ion separation by supported liquid membranes under electrodialysis conditions

Electrodialysis (ED) is a membrane-based process in which ions are transported under the influence of an externally applied electrical potential. Ion-exchange membranes (IEMs) are key components in ED processes. There are two types of IEMs: (1) cation-exchange membranes (CEMs), which contain fixed, negatively charged groups, and (2) anion...

Static and Dynamic properties of Cubic Chiral Magnets

The research presented in this thesis focuses on chiral magnets, where skyrmion lattices are stablised by magnetic fields. Neutron scattering, magnetisation and magnetic susceptibility measurements have been performed on several typical chiral magnets such as the multiferroic insulator Cu2OSeO3 and the metallic MnSi and FeGe...

Multi-Scale Modelling of Fatigue of Wind Turbine Rotor Blade Composites

In this research, extensive fatigue tests were performed on single glass fibres and composite coupons. Comparison of the test results shows that there is a significant difference between the fibre and composite fatigue behaviour. In order to clarify this difference, a multi-scale micro-mechanical model was developed. This model predicts fatigue...

Multiscale Modeling of Fracture Processes in Cementitious Materials

Concrete is a composite construction material, which is composed primarily of coarse aggregates, sands and cement paste. The fracture processes in concrete are complicated, because of the multiscale and multiphase nature of the material. In the past decades, comprehensive effort has been put to study the cracks evolution in concrete, both...
