1. Production and transformation of organic compounds from renewable feedstock : Catalytic approaches
Abstract : This thesis is focused on the development of strategies for lignocellulosic biomass valorization. The thesis consists of two parts.The first part of the presented work is related to the catalytic fractionation of biomass (lignin-first approach) and the production of monomeric compounds from lignocellulose.

2. Exploring Novel Catalytic Chalcogenide Antioxidants
Abstract : This thesis is concerned with the synthesis and evaluation of regenerable chalcogen containing antioxidants. Variously substituted 2,3-dihydrobenzo[b]selenophene-5-ol antioxidants were evaluated in order to gain information about structure/reactivity-relationships. READ MORE

3. Catalytic Reduction of NOx on Heavy-Duty Trucks
Abstract : The objective of the work described in this thesis is to identify the principles and parts of an aftertreatment system for the catalytic NOx reduction for heavy-duty diesel vehicles, and to demonstrate such a system in full-scale. The reducing agent is diesel fuel. READ MORE

4. Catalytic Asymmetric Ketone and Alkene Reductions Using Transition Metal Complexes
Abstract : This thesis contains seven papers dealing with iridium and ruthenium based catalytic asymmetric reductions, either of ketones into chiral alcohols, or olefins into chiral alkanes. The first part of the thesis describes how we have designed and evaluated new bicyclic ligands containing either N,S or N,N chelating atoms. READ MORE

5. Structure, Morphology, and Catalytic Properties of CuOx/CeO2 Model Catalysts
Abstract : Cerium dioxide, or ceria, is a chemically stable oxygen ion conducting material with a capacity to store and release oxygen, and is therefore extensively used in combustion catalysts. The Cu-Ce-O system has been identified as one of the most active catalysts for the combustion of carbon monoxide. READ MORE
