11. Studies of hydrocarbon-assisted selective catalytic reduction of nitrogen oxides - DME as reductant and reaction mechanism over silver/alumina
Abstract : Increasing amounts of carbon dioxide are attaining worldwide growing attention as one probable cause for global warming. Together with the expected peak in oil production and an increasing oil demand, this results in a greater interest in more fuel effective lean burn engines (i.e. operation with excess oxygen).

12. Thin film growth and characterization of Ti-(Si,Ge)-C compounds
Abstract : This thesis describes growth by de magnetron sputtering of thin film Ti-Si-C and Ti-Ge-C materials, with an emphasis on the deposition conditions for nanocomposite and epitaxial growth at low and high temperature processing, respectively. In the Ti-Si-C materials system, I have synthesized nanocomposite thin films from a Ti3SiC2 compound target in an Ar discharge on Si(100), Al2O3(0001), and Al substrates at low substrate temperature (300 oC and below).

13. Selective Catalytic Reduction of NOx over Alumina-Supported Silver and Indium During Lean Operation
Abstract : Catalytic emission control for vehicles was first applied in the 1970’s. The first such catalysts were designed to oxidize unburned hydrocarbons (HC) and carbon monoxide (CO). READ MORE

14. Some Fundamental Aspects Concerning Secondary Steelmaking
Abstract : The present thesis deals with some aspects concerning secondary metallurgy of steel where there is little or very inconsistent information in the literature. More specifically, it is devoted to the studies on high temperature phase equilibria in the Al2O3-CaO-MgO-SiO2 system, the formation of ladle glaze and the thermodynamics of magnesium in liquid iron.

15. The Multiple Faces of Interfaces : Electron microscopy analysis of CuInSe2 thin-film solar cells
Abstract : The CIS solar cell family features both a high stability and world-class performances. They can be deposited on a wide variety of substrates and absorb the entire solar spectrum only using a thickness of a few micrometers. READ MORE
