  4. 2. Dynamics in Ceria and Related Materials from Molecular Dynamics and Lattice Dynamics

    Author : Anders Gotte; Kersti Hermansson; Micael Baudin; Anatoly Belonoshko; Uppsala universitet; []
    Keywords : Inorganic chemistry; molecular dynamics; diffusion; surface dynamics; ionic surfaces; Oorganisk kemi;

    Abstract : 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. READ MORE

  5. 3. Substructure dynamics : In-situ annealing coupled with numerical modelling

    Author : Verity Borthwick; Stockholms universitet; []
    Keywords : ;

    Abstract : 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. READ MORE

  6. 4. Modal Dynamics of Vertical-Cavity Surface-Emitting Lasers

    Author : Johan Gustavsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transverse modes; noise; modeling; Semiconductor laser; dynamics; vertical-cavity surface-emitting laser;

    Abstract : 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. READ MORE

  7. 5. An X-ray Based Spectroscopic Study of Structure Influencing Electrons : Fragmentation, Ultrafast Charge Dynamics and Surface Composition

    Author : Geethanjali Gopakumar; Olle Björneholm; Carl Caleman; Isaak Unger; Ruth Signorell; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fragmentation; ICD; ETMD; Ultrafast electron dynamics; Surface propensity;

    Abstract : 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. READ MORE
