Sammanfattning : Biomimetic chemistry is directed towards the simulation of enzymatic reactivity with synthetic analogues. In this thesis a quantum chemical method has been employed to study the mechanism of highly reactive iron-oxo complexes involved in oxygenation and chlorination of organic substrates. LÄS MER
Sammanfattning : The cytochromes P450 are a large enzyme family that is found in all living organisms and takes part in both endogenous and exogenous metabolism. They are primarily mono-oxygenases and perform a wide range of reactions. LÄS MER
Sammanfattning : This study is a contribution to the development of the theory of bank portfolio selection behaviour. A central idea in the study is that this behaviour can be explained to a large extent by liquidity considerations which banks make in view of the partly uncontrollable and partly unforeseeable fluctuations which occur in their deposits and to a certain extent, also in their loans.

4. The effect of core-valence correlation on transition metal clusters and surfaces : a theoretical study
Sammanfattning : Ten studies, using the methods of quantum chemistry to study transition metal clusters and surfaces, are presented. The effect of including correlation between the core and valence-electrons are studied, both with an approximative operator and with the core-electrons explicitly correlated. LÄS MER
5. Thermal Expansion and Local Environment Effects in Ferromagnetic Iron-Based Alloys : A Theoretical Study
Sammanfattning : The Nobel Prize for Physics 1920 was awarded to C.-E. Guillaume for his discovery of properties of nickel steels. He had previously observed that certain iron-nickel alloys exhibit the Invar effect i. LÄS MER
