On October 28, WHO statistics show that air pollution caused by nitrogen dioxide causes more than 7 million deaths each year, especially for children and the elderly. Royal Polytechnic University in Australia is developing nitrogen dioxide gas detection technology. New technology can detect nitrogen dioxide air pollution levels through smart phone sensors and promptly issue warnings to users. Kourosh Kalantar-zadeh, a professor at the Royal Melbourne Institute of Technology, is in charge of the project. Current versions of the sensor can utilize disulfide sheets to absorb diffuse nitrogen dioxide molecules in the air. By analyzing the amount of nitrogen dioxide molecules on the sheet, the sensor determines the concentration of nitrogen dioxide gas in the immediate surroundings. Disulfide flakes and natural nitrogen dioxide molecules have a natural affinity. As a result, disulfide flakes can ignore other gas molecules and make the sensor measurements more accurate. Caloundhal-Zade said: "Currently, testing tools are either too expensive or can not distinguish other gases. The public lack of effective testing tools, which is to reduce the harmful effects of nitrogen dioxide, the main obstacle. Our technology not only low cost , And the actual effect is superior to other detection techniques. " The Royal Melbourne Institute of Technology has co-developed the technology with the Chinese Academy of Sciences. University of California scientists are also developing low-cost techniques for detecting concentrations of nitrogen dioxide.
