1. Hydrotreatment of lignin and its bio-oils over transition metal sulfide-based supported and unsupported catalysts
Abstract : The scarcity of fossil feedstocks and the deterioration of the current global climate condition have prompted the search for reliable alternatives for fossil fuel replacement. Biomass feedstocks such as lignin can be used to produce renewable bio-oils that can fill the gap left by fossil-derived oils. READ MORE

2. Slurry Hydrotreatment of Biomass Materials over Metal Sulfide-based Supported and Unsupported Catalysts
Abstract : The scarcity of fossil feedstocks and the deterioration of the current global climate condition have prompted the search for reliable alternatives for fossil fuel replacement. Biomass feedstocks are abundant, carbon-rich, and renewable bioresources that can be used to produce renewable bio-oils that can fill the gap left by fossil-derived oils. READ MORE

3. On the Formation of Low-Friction Tribofilms in Me-DLC – Steel Sliding Contacts
Abstract : The present thesis thoroughly treats a special friction reduction phenomenon that may appear in boundary lubricated tribological contacts, of the type encountered in numerous mechanical components made of steel. The phenomenon involves the formation of a special type of tribofilm that offers very low coefficients of friction. READ MORE

4. Self-Lubricating Laser Claddings in the Context of Hot Metal Forming
Abstract : Laser cladding is a coating technique with significant advantages like the high quality of the resulting layers, their excellent metallurgical bonding to the substrate or the possibility to repair/rework high-value mechanical components. In recent years, the incorporation of solid lubricants to the base powder in order to produce self-lubricating claddings has been shown in the literature to be possible, with several of the described coatings being able to operate at high temperatures with low friction and wear.

5. Reactivity of Transition-Metal Compounds from Electronic Structure
Abstract : Transition-metal carbides (TMC's), nitrides, and sulfides belong to the class of materials known as transition-metal compounds (TMX's). Besides having intriguing properties, these materials are relevant for, e.g., growth and catalysis. READ MORE
