1. Multiscale Modelling of Reinforced Concrete
Sammanfattning : Since concrete cracks at relatively low tensile stresses, the durability of reinforced concrete structures is highly influenced by its brittle nature. Cracks open up for ingress of harmful substances, e.g. chlorides, which in turn cause corrosion of the reinforcement. LÄS MER
2. Multiscale Modelling of Reinforced Concrete Structures
Sammanfattning : Concrete cracks at relatively low tensile stresses; cracks open up for ingress of harmful substances, negatively affecting the durability of reinforced concrete structures. Crack widths are thus limited in the design codes, and accurate predictions are needed, especially for large reinforced concrete structures such as bridges or nuclear reactor containment buildings.

3. Multiscale Modelling of a Nanoelectromechanical Shuttle
Sammanfattning : Nanoelectromechanical systems couple mechanical and electronic degrees of freedom creating a new type of electrical components. The nanoelectromechanical shuttle consists of a double junction with a movable central island. LÄS MER
4. Metal film growth on weakly-interacting substrates : Multiscale modeling
Sammanfattning : Thin films are nanoscale layers of material used to functionalize surfaces or to serve as building blocks in more complex devices. In recent years, thin metal films have become vital for modern devices within, e.g. LÄS MER
5. Multiscale modelling of total pressure effects on complete methane oxidation over Pd/Al2O3
Sammanfattning : The models used in heterogeneous catalysis are becoming more advanced and the literature shows an increased interest in incorporating the atomistic scale into microkinetics. Coupling kinetics based on first-principles calculations to macroscopic effects can pave the way towards more comprehensive modelling methods and to tailored catalyst designs. LÄS MER
