BEIJING -- Chinese scientists have discovered a way to improve the antibacterial performance of titanium biomedical material used as dental and orthopedic implants.Titanium is one of the most widely used materials for medical implants because it has excellent biocompatibility and strength. However, titanium and titanium-based materials lack any anti-bacterial capacity, resulting in a risk of bacteria infection after implantation.Previous strategies such as anti-bacterial coatings and UV lighting were designed to kill bacteria.Researchers from Beijing Institute of Nanoenergy and Nanosystems, Chinese Academy of Sciences (CAS), Shenzhen Institutes of Advanced Technology, CAS as well as City University of Hong Kong have developed a method to improve biomedical titanium's anti-bacterial properties.Titanium gains a strong ability to kill surrounding bacteria after an external electrical current is applied. After the charging, the biocompatibility of the material remains unchanged.The research was published on the journal Nature Communications on May 24.The research provides insights into the use of electricity to improve biomaterials as a complement to other antibacterial measures.This approach is promising for clinical application, according to Feng Hongqing, one of the researchers.We can apply electricity to the titanium material before implantation into the body. The enhanced antibacterial performance will reduce postoperative infection risk, Feng said. rainbow silicone wristbandswide rubber braceletsblank-wristbandmedical id silicone wristbandssilicone wristbands
The Fengyun-2H meteorological satellite, carried by a Long March-3A rocket, is launched from the Xichang Satellite Launch Center in Southwest China's Sichuan province, June 5, 2018. [Photo/Xinhua] XICHANG - China on Tuesday launched the new Fengyun-2H meteorological satellite to improve the accuracy of weather forecasting and provide better meteorological services to countries participating in the Belt and Road Initiative. The Fengyun-2H was launched on a Long March-3A rocket at 9:07 p.m., Beijing Time, from the Xichang Satellite Launch Center in Southwest China's Sichuan province. It was the 277th mission of the Long March rocket series. A geostationary orbit satellite, Fengyun-2H is the last in the Fengyun-2 series. The Fengyun-4 series will dominate China's new generation geostationary orbit meteorological satellites, said Zhao Jian, deputy director of the Department of System Engineering of China National Space Administration (CNSA). In response to a request from the World Meteorological Organization (WMO) and the Asia-Pacific Space Cooperation Organization (APSCO), the position of Fengyun-2H will be changed from original 86.5 degrees east longitude to 79 degrees east longitude. This means the Fengyun series satellites will be able to cover all the territory of China, as well as countries along the Belt and Road, the Indian Ocean and most African countries, according to the CNSA. silicone wristbandsrubber wristbands custom cheapcustom-rubber-braceletspersonalized silicone braceletswide rubber bracelets<%2fcenter>
