21. Green aromatics for a bio-based economy - Valorization of biomass derived model compounds over zeolites studied by online analysis
Sammanfattning : In the strive towards sustainable chemical production, its carbon-based products can no longer be produced from fossil resources but need to be manufactured from a renewable feedstock. Simple aromatic building blocks like benzene, toluene and xylenes (BTX) can be obtained by catalytic valorization of biomass derived platform molecules such as furans provided efficient catalysts can be formulated.

22. Asymmetric and symmetric hydration of hydrated anions in aqueous solution
Sammanfattning : The interaction between solvent and solute is a very important chemical property that has large impact on the chemical reactions taking place. In Paper I and II the structure of hydrated sulfite, selenite and selenate in aqueous solutions are determined and compared. LÄS MER
23. Porous Polymeric Monoliths by Less Common Pathways : Preparation and Characterization
Sammanfattning : This thesis focuses on my endeavors to prepare new porous polymeric monoliths that are viable to use as supports in flow-through processes. Polymer monoliths of various porous properties and different chemical properties have been prepared utilizing the thermally induced phase separation (TIPS) phenomenon and step-growth polymerization reactions.

25. Tailoring of Transition Metal Silicides as Protective Thin Films on Austenitic Stainless Steel
Sammanfattning : The objective of this study is to make use of transition metal silicides in a novel way as protective thin films on engineering metals. It can then be possible to take advantage of the potentially good corrosion resistance of metal silicides while compensating for their brittle nature by the ductile bulk material. LÄS MER
