1. Molecular Beam Studies of Ice Surface Properties
Sammanfattning : .... LÄS MER
2. Dynamics in Ceria and Related Materials from Molecular Dynamics and Lattice Dynamics
Sammanfattning : In discussions of heterogeneous catalysis and other surface-related phenomena, the dynamical properties of the catalytic material are often neglected, even at elevated temperatures. An example is the three-way catalyst (TWC), used for treatment of exhaust gases from combustion engines operating at several hundred degrees Celsius. LÄS MER
3. Substructure dynamics : In-situ annealing coupled with numerical modelling
Sammanfattning : The understanding of substructural behaviour during post-deformational annealing is key to interpreting rheological adjustments during tectonic change, and the processes which cause them. The focus of this study is to use coupled in-situ experimental techniques with numerical simulation to increase understanding of substructure dynamics in geological materials. LÄS MER
4. Modal Dynamics of Vertical-Cavity Surface-Emitting Lasers
Sammanfattning : In this work, a comprehensive dynamic model has been developed for simulating a novel semiconductor laser type, referred to as the Vertical-Cavity Surface-Emitting Laser (VCSEL). The high-speed behavior was simulated and compared to experiments, where excellent agreement was found. LÄS MER
5. An X-ray Based Spectroscopic Study of Structure Influencing Electrons : Fragmentation, Ultrafast Charge Dynamics and Surface Composition
Sammanfattning : The structure of biomolecules, such as proteins, is intimately connected to the function of the molecules. These structures are often studied using X-ray diffraction. However, the interaction of the X-ray photons with the molecule can excite or ionize its electrons which in turn can causes changes in the molecular structure. LÄS MER
