New Applied Surface Science Findings from National Research Council Outlined

January 31, 2014



By a News Reporter-Staff News Editor at Science Letter -- Current study results on Science have been published. According to news reporting out of Rome, Italy, by NewsRx editors, research stated, "In this study the proof of principle of the use of naked semiconductor directly generated on metal oxide surface as mediators in gas sensing is provided."

Our news journalists obtained a quote from the research from National Research Council, "Successive ionic layer absorption and reaction (SILAR) technique has been applied to sensitize a WO3 thin film with CdS quantum dots. Response to gases of bare WO3 is deeply modified: quantum dots dramatically increase the metal oxide conductance, otherwise rather poor, and modify the capability of detecting environmental pollutants, such as CO and NO2."

According to the news editors, the research concluded: "A modified sensing mechanism is proposed to rationalize the mediation exerted by the semiconducting active layer on the interaction between gaseous species and WO3 surface."
