in the present study, electrophoretic deposition (EPD) was used to obtain dense and crack-free layers of Al2O3 on carbon substrate. Microstructural study of the obtained layers by scanning electron (SEM) and optical microscopy (OM) approved that crack-free layers can be obtained by EPD technique. According to obtained results, isopropanol is a suitable media to obtian compact layers which is at...

In this paper, we present and review recent developments in the high-density plasma chemical vapor deposition (HDP CVD) of silicon-based dielectric films, and of films of recent interest in the development of lower-dielectric-constant alternatives. Aspects relevant to the HDP CVD process and using the process to achieve interlevel insulation, gap filling, and planarization are discussed. Result...

An original dimensionless study of the pure evaporation and precipitation stages of a spray pyrolysis process has been performed. An estimation of he evaporation time is proposed and the influence of the main processing parameters has been investigated. For operating conditions corresponding o industrial requirements, the main limiting step of the evaporation stage is thermal transfer from the ...

The Adirondacks of New York State, USA is a region that is sensitive to atmospheric mercury (Hg) deposition. In this study, we estimated atmospheric Hg deposition to the Adirondacks using a new scheme that combined numerical modeling and limited experimental data. The majority of the land cover in the Adirondacks is forested with 47% of the total area deciduous, 20% coniferous and 10% mixed. We...

Increases in reactive nitrogen deposition are a growing concern in the U.S. Rocky Mountain west. The Rocky Mountain Airborne Nitrogen and Sulfur (RoMANS) study was designed to improve understanding of the species and pathways that contribute to nitrogen deposition in Rocky Mountain National Park (RMNP). During two 5-week field campaigns in spring and summer of 2006, the largest contributor to r...
