21. Charge and proton dynamics in molecules and free clusters : from atomic to nanometer scale
Sammanfattning : The origin of properties in complex systems can often be traced to mechanisms involving charge and energy transfer in only a few embedded molecules. The detailed study of the time evolution of these mechanisms in their original environment is a challenging task. LÄS MER
22. Engineering ferroelectric domains and charge transport by proton exchange in lithium niobate
Sammanfattning : Ferroelectrics are dielectric materials possessing a switchable spontaneous polarization, which have attracted a growing interest for a broad variety of applications such as ferroelectric lithography, artificial photosynthesis, random and dynamic access memories (FeRAMs and DRAM), but also for the fabrication of devices for nonlinear optics, etc. All the aforementioned applications rely on the control of the ferroelectric domains arrangement, or the charge distribution and transport.

23. Prokaryotic respiratory supercomplexes : Studies of interactions between complexes III and IV
Sammanfattning : Respiratory processes for cellular energy conversion are carried out by the membrane-associated enzymes of the electron transfer chain (ETC). In recent years there has been emerging data showing that the members of the ETC organize into higher-level assemblies called supercomplexes (SCs) whose functional relevance is not yet fully understood.

24. Computational Analysis of Gas Flow and Heat Transport Phenomena in Ducts Relevant for Fuel Cells
Sammanfattning : The thesis concerns modeling, simulation and numerical analysis of heat and mass transport, and fluid flow in ducts of both solid oxide fuel cells (SOFCs) and proton exchange membrane fuel cells (PEMFCs). The unique fuel cell boundary conditions (thermal, mass) for the flow ducts in fuel cells are identified and applied. LÄS MER
25. Determining Ligand- and Lipid- Interactions of SLC Transporters
Sammanfattning : Solute carrier transporters (SLCs) mediate the inter- and intra- cellular trafficking of a plethora of substrates and are essential to cell homeostasis. Despite their importance to human physiology and their potential as therapeutic targets, many SLCs are considered orphans as the physiological substrate has not been experimentally determined.
