Investigators from Wuyi University Zero in on Chemical Sensors and Actuators

May 27, 2014



By a News Reporter-Staff News Editor at Journal of Technology -- Fresh data on Chemical Sensors and Actuators are presented in a new report. According to news originating from Guangdong, People's Republic of China, by VerticalNews correspondents, research stated, "A self-heating effect has been observed in the gasochromic coloration of Pt coated WO3 (Pt-WO3) nanowire films, and its temperature rise rate is found to be strongly dependent on the initial temperature and the time of the sample exposed to air."

Our news journalists obtained a quote from the research from Wuyi University, "X-ray photoelectron spectroscopy is applied to investigate the catalyst poisoning and reactivation of Pt-WO3 nanowires in air, and the results indicate that the Pt nanoparticles can be poisoned by chemisorbed oxygen atoms in air, causing the self-heating effect to be suppressed at room temperature."

According to the news editors, the research concluded: "The mechanism response for the occurrence of the self-heating effect has also been discussed in depth."
