1. Quantum Chemical Interpretation of Protein Crystal Structure
Sammanfattning : An initial model in the crystallographic structure determination process, usually contains many errors. To produce an accurate model, one must carry out several cycles of crystallographic refinement. LÄS MER
2. Hydrogen in oxides: a density-functional study of thermodynamic and kinetic aspects
Sammanfattning : Many solid oxides, especially those possessing a perovskite structure, exhibit significant proton conductivity when being acceptor doped and placed in hydrogen-containing atmospheres. Consequently, they have attracted attention foruse as solid membranes in electrochemical devices such as gas sensors, steam electrolyzers and fuel cells. LÄS MER
3. Studies on the crystal and molecular structure of some flavin derivatives in different states of oxidation and protonation
Sammanfattning : .... LÄS MER
4. Temporal Modulation in Fluorescence Spectroscopy and Imaging for Biological Applications
Sammanfattning : This thesis explores the benefits of intensity modulation for the purpose of extending the range of applications of fluorescence spectroscopy and imaging in cellular and molecular biology and medicine. Long-lived transient states of fluorescent molecules can, because of their long lifetimes, be used to detect subtle changes in the microenvironment of the molecule. LÄS MER
5. Computational Studies of Nitrogenase
Sammanfattning : AbstractNitrogenase is the only enzyme that can convert the inert nitrogen molecule to ammonia, so that it can be used for biomass production and in biosynthetic pathways. It contains a complicated acitve site, composed of eight metal ions, nine sulfur ions and one carbide ion (the FeMo cluster). LÄS MER
