Hydrogen terminated silicon surfaces: Development of sensors to detect metallic contaminants and stability studies under different environments
… a silicon-based sensor to detect trace levels of metallic contaminants in hydrofluoric acid. The sensor performance with respect to two non-contaminating reference electrode systems was evaluated. In the first case, conductive diamond was used as a reference electrode. In the second case, a dual …

Phase field model for precipitates in crystals
… Oxygen precipitates are useful for gathering metallic contaminants away from the device regions and for increasing the mechanical strength of the wafer [Borghesi, 1995], but they also can destroy the electrical and mechanical characteristics of the semiconductor and microelectronic devices …

Part A: Investigation of a newly identified plant Hernandia didymantha Donn, synthesis of phenethyl cinnamide Part B: Selective removal of ascaridol from the essential oil of Chenopodium ambrosioides var ambrosioides Part C: Synthesis of canophyllol analogues
… quinoline by washing several times with hexanes. Metallic contaminants in the oil such as lead and palladium which are components of the Lindlar catalyst were effectively removed by stirring the final product with 1% silica gel followed by filtration. This method appears to be inexpensive and thus …
