21. Catalytic Conversion of Undesired Organic Compounds to Syngas in Biomass Gasification and Pyrolysis Applications
Abstract : Reliable energy supply is a major concern and crucial for development of the global society. To address the dependency on fossil fuel and the negative effects of this reliance on climate, there is a need for a transition to cleaner sources. An attractive solution for replacing fossil-based products is renewable substitutes produced from biomass. READ MORE

22. Fundamental studies of catalytic systems for diesel emission control
Abstract : Due to global lean exhaust gas and new emission regulations, exhaust aftertreatment systems of diesel engines are more and more sophisticated and composed of a series of catalytic units. In the present work, two of these catalytic systems were studied with different approach. READ MORE

23. New C-C coupling Reactions Enabled by Main-group Organometallics
Abstract : The carbon-carbon bond has always been at the very core of chemical research. Strategies for the creation of C−C bonds are one of the keys to the construction game that organic chemists play with the building blocks provided by Nature, with the ultimate goal of producing useful molecular structures that will serve society as medicines, materials, imaging tools, catalysts, and ligands (to mention but a few).

24. Coordination of Phosphine-Thioether Ligands to Low-valent Metal Centers
Abstract : The reactivity of the phosphine-thioether ligands bis(2-diphenylphosphino) ethylthio)ethane (PSSP), bis(2-(diphenylphosphino) ethyl)sulfane (PSP), PPh2CH2CH2SMe (PS), PPh2(o-C6H4SMe (PortoS), and PPh(o-C6H4SMe)2 (PSS) towards low-valent carbonyl clusters has been studied. In all structurally characterized clusters, the ligand donor atoms are terminally coordinated. READ MORE

25. Varved lake sediments and diagenetic processes
Abstract : Varved (annually laminated) sediments are of great interest for inference of past environmental conditions, as they provide dated records with high time resolution. After deposition, the sediment varves are affected by diagenesis; i.e., chemical, physical and biological changes that occur within the sediment. READ MORE
