Combustion processes are the most important source of metal in the atmosphere and need to be better understood to improve flue gas treatment and health impact studies. This combustion experiment was designed to study metal partitioning and metal speciation in the gaseous and particulate phases. A light fuel oil was enriched with 15 organometallic compounds(More)
Pyrocarbon materials containing various amounts of boron have been prepared by LPCVD from BCl3–C3H8–H2 precursor mixtures. The growth rate is increased with respect to pure pyrocarbon deposition. By increasing BCl3 / (C3H8 + BCl3) ratio up to 85%, the incorporation of boron can reach 33 at.%. A small amount of boron (e.g. 8 at.%) highly enhances the(More)
The European directive 2000/53/EC limits the use of Cr(VI) in vehicle manufacturing. Although a maximum of 2 g of Cr(VI) was authorised per vehicle for corrosion prevention coatings of key components, since July 2007 its use has been prohibited except for some particular applications. Therefore, the objective of this work was to develop direct analytical(More)
Analysis of microscopic modifications and macroscopic surface properties of polystyrene thin films treated under DC pulsed discharge conditions. Author manuscript, published in "Surface and Interface Analysis 37 (2005) 544-554" 2 Abstract Using a DC pulsed plasma for the polymer surface treatment allows the attainment of macroscopic modifications of the(More)
In this article, we report how variations in the preparation method of boron-nitride-supported noble metal catalysts may influence the surface characteristics of the active phase and consequently the potential applications as catalysts for oxidation reactions. The deposition and the dispersion of the active phase are strongly influenced by the preparation(More)
The influence of the oxide support (i.e., Al2O3, Nb2O5, SiO2, and TiO2,) on the surface properties, reduction and oxidation properties, acid-base properties, and catalytic activity of supported indium oxide catalysts has been investigated by temperature-programmed reduction/oxidation, thermogravimetry coupled to differential scanning calorimetry, ammonia(More)
