16. Influence of total pressure on complete oxidation of methane over Pd/Al2O3 catalysts
Sammanfattning : Natural gas and biogas, which have methane as their main component, are interesting choices of fuel to reduce the anthropogenic emissions of greenhouse gases. However, as methane is a greenhouse gas, uncombusted methane should be removed from the combustion gases. Emission control catalysts can preferably be used to completely oxidise methane. LÄS MER
17. Multiscale modelling of total pressure effects on complete methane oxidation over Pd/Al2O3
Sammanfattning : The models used in heterogeneous catalysis are becoming more advanced and the literature shows an increased interest in incorporating the atomistic scale into microkinetics. Coupling kinetics based on first-principles calculations to macroscopic effects can pave the way towards more comprehensive modelling methods and to tailored catalyst designs. LÄS MER
18. Partial methane oxidation: insights from first principles and micro-kinetics calculations
Sammanfattning : Partial methane oxidation is a much-desired reaction with some intriguing challenges. Not only is there a need to activate methane and oxygen, but there is also a need to control the selectivity and prevent over-oxidation to thermodynamically more stable products, like carbon dioxide and water.

19. Microkinetic Modeling of Nanoparticle Catalysis using Density Functional Theory
Sammanfattning : Heterogeneous catalysis is vitally important to modern society, and one path towardsrational catalyst design is through atomistic scale understanding. The atomistic scalecan be linked to macroscopic observables by microkinetic models based on first-principlescalculations. LÄS MER
20. High (valent) on O2 : Ribonucleotide Reductase and Methane Monooxygenase
Sammanfattning : Macromolecular X-ray crystallography (MX) is a powerful method to investigate protein structures. However, proteins with redox-active centres and radicals are very susceptible to photoreduction. LÄS MER
