11. Imidazole containing polymers complexed with Cu2+ and Zn2+
Sammanfattning : An enormous problem for the shipping industry is fouling of marine organisms such as algae andbarnacles on the boat hull. The negative consequences for the society are both economical as well asenvironmental. To prevent fouling in general, biocides are typically incorporated directly into the paint. LÄS MER
12. Solubility and Surface Complexation Studies of Apatites
Sammanfattning : Apatites are a diverse class of phosphate minerals that are important in a great variety of natural and industrial processes. They are, for example, used as raw material in fertiliser production and in the remediation of metal-contaminated soils. LÄS MER
13. Surface and Bulk Reactivity of Iron Oxyhydroxides : A Molecular Perspective
Sammanfattning : Iron oxyhydroxide (FeOOH) mineral plays an important role in a variety of atmospheric, terrestrial and technological settings. Molecular resolution of reactions involving these minerals is thereby required to develop a fundamental understanding of their contributions in processes taking place in the atmosphere, Earth’s upper crust as well as the hydrosphere.

14. Improving interpretation by orthogonal variation : Multivariate analysis of spectroscopic data
Sammanfattning : The desire to use the tools and concepts of chemometrics when studying problems in the life sciences, especially biology and medicine, has prompted chemometricians to shift their focus away from their field‘s traditional emphasis on model predictivity and towards the more contemporary objective of optimizing information exchange via model interpretation. The complex data structures that are captured by modern advanced analytical instruments open up new possibilities for extracting information from complex data sets. LÄS MER
15. Catalysis for Lean NOx Reduction - Aspects of Catalyst Synthesis and Surface Acidity
Sammanfattning : From both economic and environmental perspectives it is desirable to reduce the consumption of fossil fuels. One route to increase the fuel efficiency for vehicles is operation in oxygen excess. However, a major problem with this technique is the lean environment, which obstructs catalytic reduction of nitrogen oxides (NOx) to harmless nitrogen. LÄS MER
