Researchers at Lanzhou University Report New Data on Titanium Dioxide Nanotechnology (Highly antibacterial activity of N-doped TiO2 thin films coated on stainless steel brackets under visible light irradiation)

By a News Reporter-Staff News Editor at Science Letter -- Investigators publish new report on Nanotechnology. According to news reporting from Lanzhou, People's Republic of China, by NewsRx journalists, research stated, "In this study, the radio frequency (RF) magnetron sputtering method was used to prepare a TiO2 thin film on the surface of stainless steel brackets. Eighteen groups of samples were made according to the experimental parameters."

The news correspondents obtained a quote from the research from Lanzhou University, "The crystal structure and surface morphology were characterized by X-ray diffraction, and scanning electron microscopy, respectively. The photocatalytic properties under visible light irradiation were evaluated by measuring the degradation ratio of methylene blue. The sputtering temperature was set at 300 degrees C, and the time was set as 180 min, the ratio of Ar to N was 30:1, and annealing temperature was set at 450 degrees C. The thin films made under these parameters had the highest visible light photocatalytic activity of all the combinations of parameters tested. Antibacterial activities of the selected thin films were also tested against Lactobacillus acidophilus and Candida albicans."

According to the news reporters, the research concluded: "The results demonstrated the thin film prepared under the parameters above showed the highest antibacterial activity."
