BEIJING - Chinese researchers have developed a new method to turn carbon dioxide, the main greenhouse gas, into clean liquid fuel such as methanol.The breakthrough might help mitigate the greenhouse effect caused by carbon emissions, and promote the development of new clean energies.A research team led by Professor Zeng Jie, at the University of Science and Technology of China, developed a new catalyzer with platinum as the raw material. The catalyzer can effectively convert carbon dioxide into methanol, which is also a basic raw material of the chemical industry.The study was published in the academic journal, Nature Nanotechnology. silicone allergy braceletwhere can you buy wristbandsneon wristbands for eventssilicone wristband braceletfundraising rubber wristbands

[Photo/Xinhua] Transportation authorities in Beijing are working on easier ways for passengers to pay for access to the city's subway system, including facial recognition technology, reports Beijing Youth Daily. The facial recognition technology, which would also strengthen security checks, is likely to be put into test runs this year, according to the report. This comes on the heels of a QR code payment system across the entire Beijing Subway system. This now allows riders to scan a QR code through an app. Scanning a QR code is said to be especially convenient at the stations near the Beijing Train Station, where the passengers sometimes have to queue for 30 minutes to buy a one-way ticket on the vending machines.
