6. Spectrally Selective Solar Absorbing Coatings Prepared by dc Magnetron Sputtering
Sammanfattning : Spectrally selective solar absorber using composite Ni-NiO as coating materials was studied. Samples were prepared by dc magnetron sputtering unit named Rulle, which is a miniature copy of an industrial roll-coater unit. LÄS MER
7. The influence of Al alloy microstructure on conversion coating formation
Sammanfattning : The formation of conversion coatings based on Ce, trivalent Cr and Ti/Zr is triggered by the local pH increase at cathodic IM sites of the aluminium alloy microstructure. The pH gradient is created over the cathodic intermetallic (IM) sites of the microstructure and its intensity is influenced by their activity which depends on their chemical composition, their size, and spatial distribution.

8. Preparation and Characterization of Sputter Deposited Spectrally Selective Solar Absorbers
Sammanfattning : The optical efficiency of a commercially available sputter deposited spectrally selective solar absorber was improved. The main purposes were to decrease the thermal emittance, increase the solar absorbtance of the absorber and to protect the substrate from degradation due to environmental influence. LÄS MER
9. Strategies for developing peptide and protein selective plastic antibodies
Sammanfattning : The objective of the thesis was to explore approaches for the development of molecularly imprinted materials with predetermined selectivity for peptide or protein targets. In particular, the work has focused on molecularly imprinted nanoparticles synthesized using solid-phase synthesis protocols. LÄS MER
10. Selective conversion of alcohols to aldehydes over metal oxide catalysts
Sammanfattning : Nowadays, transition metal oxide catalysts are employed to a large extent in many chemical processes for the selective production of chemicals and intermediates. Although metal oxides are mostly known as oxidation catalysts, they can successfully catalyze a wide range of reactions, such as dehydration. LÄS MER
