1. Green Aromatics: Catalytic Valorisation of bio-derived 2,5-dimethylfuran over Zeolites and Zeotypes
Sammanfattning : This thesis discusses the use of biomass as a potentially green feedstock for the chemical industry in the urgent shift away from fossil resources. I elaborate on reasons why we cannot afford to burn virgin biomass for energy production, among them a variety of ecosystem services that forests and other lands provide. LÄS MER
2. Methane oxidation over palladium oxide. From electronic structure to catalytic conversion
Sammanfattning : Understanding how catalysts work down to the atomic level can provide ways to improve chemical processes on which our contemporary economy is heavily reliant. The oxidation of methane is one such example, which is important from an environmental point of view. LÄS MER
3. Synthesis and Photochemical Characterisation of Photoactive Compounds for Molecular Electronics
Sammanfattning : In this modern age of technology, communication is highly reliant on computing devices such as mobile phones and computers. The advent of artificial intelligence (AI) and internet of things (IoT) as well as the widespread use of user-generated contents (UGC) are demanding more computing power and large data storage.

4. Water film-mediated mineralogical transformations and photocatalytic reactions
Sammanfattning : Mineral particles capture water vapor in the atmosphere in the form of water films that are only few monolayers thick. Water films form nanoscale hydration environments that mediate a wide range of important reactions in nature and technology. LÄS MER
5. 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
