Recent Findings in Chemical Sensors and Actuators Described by Researchers from Northwest Normal University

February 25, 2014



By a News Reporter-Staff News Editor at Journal of Technology -- Investigators publish new report on Chemical Sensors and Actuators. According to news reporting out of Lanzhou, People's Republic of China, by VerticalNews editors, research stated, "In this paper, a novel graphene-graphene oxide (GR-GO) nanocomposite which could be dispersed well in water was fabricated by mixing GR and GO together with the help of ultrasonication. The significant advantage of the method developed here is the omission of any stabilizing compound or organic solvent."

Our news journalists obtained a quote from the research from Northwest Normal University, "The prepared material was characterized by the scanning electron microscopy, transmission electron microscopy, Raman spectroscopy and electrochemical impedance spectra. The application of GR-GO nanocomposite in simultaneous determination of hydroquinone (HQ) and catechol (CC) was investigated by cyclic voltammetry and differential pulse voltammetry. The oxidation peak potential difference between HQ and catechol CC was about 102 mV, which was wide enough to clearly discriminate the dihydroxybenzene isomers."

According to the news editors, the research concluded: "In the presence of 50 mu M isomer, the oxidation peak currents of HQ and CC were linear over the range of 0.5-300 mu M with the detection limits of 0.16 mu M (S/N=3) for HQand 0.2 mu M (S/N = 3) for CC, respectively."
