Reports on Nanowires Findings from University of Barcelona Provide New Insights

August 22, 2014



By a News Reporter-Staff News Editor at Science Letter -- Data detailed on Nanowires have been presented. According to news originating from Barcelona, Spain, by NewsRx correspondents, research stated, "Copper (II) oxide (CuO) is a metal oxide suitable for developing solid state gas sensors. Nevertheless, a detailed insight into the chemical-to-electrical transduction mechanisms between gas molecules and this metal oxide is still limited."

Our news journalists obtained a quote from the research from the University of Barcelona, "Here, individual CuO nanowires were evaluated as ammonia (NH3) and hydrogen sulphide (H2S) sensors, validating the p-type character of this semiconductor. The working principle behind their performance was qualitatively modeled and it was concluded that adsorbed oxygen at the surface plays a key role necessary to explain the experimental data."

According to the news editors, the research concluded: "Compared to their counterparts of SnO2 nanowires, an appreciable sensitivity enhancement to NH3 for concentrations below 100 ppm was demonstrated."
